Air Intakes, Electric Supercharge

Ok, I've got a FABSPEED intake kit, an EVO intake kit, and the original intake hardware. I'm going to order an electric supercharger fan and try to make something work from these parts. Has anyone tried this before? I've seen the echargers on older 911's but never a 996 variant. My car is fast, but it can be faster! They say 7-10% gain is the normal. That would put me in the upper 300's if it works....................... What are your thoughts? Has anyone experimented with NOS? What are some other tricks? My car is already very light at about 2820 lbs.

What mods are you installing to get you to the upeer 300's? An electric fan won't do it.

why do you have 2 intake kits?

Dallas, Have you weighed you car at 2820 or are you estimating. I suppose it is possible. My race car is at 2875 with a roll cage but I can't imagine getting a street car that light. As for the air fan, I think I would get a money back guarantee if I were you. Is there a web site? NOS is always interesting but I've never thought it made much sense in a 911. The car is meant to turn fast, stop fast and be very durable on the track. NOS seems better suited for cars that you want to make go very fast in a straight line. Might be fun though. Jim

2912 minus mufflers, minus spare, minus cats. I know a fan won't do it, I'm not a dumbass. The car has been setup with many modifications and is presently around 340 hp. This fan kit promises 4%-6% guarantee with estimates of 7-8%. If you go with two fans, it's more than 10%. I know this sounds like a dumb idea but hey, why not try it................ If it does not work, I can take it off. Also, the intakes are not all on my car at one time, I've tried several different intakes and have extra parts. I'm planning on using these parts to adapt the fan to my car. If it makes 20 hp, I'm happy. My car is already much faster than most 911's in the area. I swallowed up a new cab just a few days ago. This car is so much quicker than my C4 could ever hope to be. I've thought about supercharging but I've not made a decision yet. I have superchargers on my boat and when I'm in the throttle, I always expect something to break. I really don't want that feeling when I'm driving my car, or do I????????

LOL!!!! Bluntly put, the amount of air that an electric fan of the size small enough to fit into the intake can not move the volume of air the needed pressure to give you their claimed power increase.....period. Sounds like a product you would find in the magazines back in the early 70's. Not only can't the fan blades move at the necessary RPM (that would be 10's of thousands of RPM's) but just the mass of the fan blades and housing will reduce the CFM of air into the intake. If you want real HP gains, go with a SC. My guess is that you will actually reduce power of the engine. Any presuure the electric fan may accidently create in the intake chamber will be thrown back at the fan causing it to slow down. No increase in pressure will ever make ot to the cylinders. JMO.

http://www.electricsupercharger.com/ Above, is a link to the website. The fan operates at over 25k rpm. Boost is 1 psi. I'm skeptical as well (ex-engineer) but the cost is minimal and I've seen other examples do well. How many miles are on your SC car? Have you had any issues? Will Porsche work on your car?

I have 45,000 miles on my March 1998 built 996 C2. More than 13,000 miles since the SC installed. No issues and I keep increasing the boost every few months. Now about 6.5 psi and loving it. I NEVER allow Porsche to touch my car. If I can't figure out the problem myself, it cannot be fixed. I guess if I need a repair that dictated Porsche tools, etc, I would have no alternative but to go to them, but that would be my last resort. I use no oil between oil changes, engine runs at factory spec temperature.

I hate to break it to you dallas but your car likely weighs well over 3000 lbs. To be under 2900 you must remove the stereo, carpeting, rear seats, replace the front seats with racing seats, replace windscreen with lexan, add mag racing wheels and light weight r compound tires, remove door panels, remove driver's window, etc., etc. Sorry, Jim

That's not true JimB!!! With his DUAL ELCTRIC BLOWERS Installed, he can remove both front wheels and simply pull a continuous wheely around town with the tremendous power his setup will give him.

Don't apologize. I'm guessing and taking the numbers from here http://www.flat-6.net/forum/showcar....ar_model_id=27 I assume these numbers are correct, but maybe it's a misprint. Anyways, I've removed more than 100 lbs from the car without a doubt, that's where my reasoning came from, 2919-mods =about 2820. I do know this, C2's are much lighter than C4's and TT's. The same page lists c4's at 3263 lbs. This is a very noticable difference between the two cars. I prefer the lightness and 2wd vs my previous c4. The c4 was great but my grandmother could have driven it fast.

Are these those "Supercharge any car for $69.95" ? The ones that "create a venturi affect in your intake tubing? Improve gas milage by up to 30% ? If so I really have to find that dyno sheet I have from a friend of mine who tried one of these things out. The car was a '96 Acura Integra, in some spots of the run it lost as much as 4 hp with only gaining a total of 1 hp in the car's vtec rpm range. How can this product still exist

HBacura, no this is an electric fan spinning 25k rpm's. There is a link above. 1999Porsche911, calm down and go pet yourself.

Dallas, I've been trying to tell you that you are full of $#@#$ nicely. 911 has been a little more direct. So here's how it is. Your car doesn't weigh 2820 lbs. I'd bet money that it's over 3100. If your mods consist of removing the cats and mufflers and adding an air intake, you have somewhere between 290 and 310 hp, not 340. Don't believe me? Put it on a dyno. Here is some unsolicited advice. Buy a Rennlist membership and dig in. There is a lot to be learned about your car. The most important thing to learn is that 99% of companies selling upgrades lie. Hell, Joe at FB will tell you that they lie just to compete with the other liars. I'm done, Jim

IF you want a true weight....go to one of those truck gas stations or the like. They have scales that you can just rollup on and get a printout fro about $5. I did this when I had to weigh my Uhaul before and after during a military move. Just make sure you gas tank is near empty and you are NOT in the car at the same time. VOILA! NOw you have a baseline to start from.

Yes, I do see now. I replied before scrolling down to see the link. Hmm never heard of it before. My question is to create power (horsepower) you need air and fuel. So that piece is supposed to create more air flow, but what is going to create more fuel? Then again, I guess it being such low boost you really don't need a fuel additive. don't know.

I wonder what kind of amps this fan draws? I bet that 2 of them exceeds the 1680 amp rating of the 996's alternator. A starter in good condition will draw maybe 250 amps for a few seconds til the car starts. Running 2 of these so called "e-rams", it would be like starting your car using as many as 8 starters. Hate to see what happens to the battery when they are drawing that much current for 15 - 20 seconds. But there must be people out there that are suckered into buying them as the company is still in business.

Here's their guarentee. It's cost yo more to get the dynos and install and uninstall the fan. LOL! Performance Guarantee: After purchasing and (properly) installing the e-RAM on your engine, you do not feel that the performance increase is what we have claimed (4%-6% HP increase), you just need to do the following within 30 days of receiving your e-RAM to get a full refund*.. Take your car to a dyno test in your area. Make dyno runs with and without the e-RAM activated, and take a picture of how it was installed. Mail the e-RAM back to us with the picture, a copy of your receipt, and a clear copy of your dyno comparison results (signed as witnessed by the technician running the dyno). If the dyno shows the e-RAM does not increase horsepower in your engine by an average of at least 4% of its previous horsepower throughout the 3000 to 6000 rpm range, and we conclude from the picture that you have installed the unit correctly, we will give you a full refund* and even pay for 1/2 your dyno fee! (up to a maximum of $50 reimbursement) *Full refund does not include shipping charges *Please see "compatibility information" section below We challenge any other manufacturer of aftermarket bolt-on horsepower devices to make the same commitment! We know it works!

1999porsche911, the information you seek is in that website. I have no idea if it will really work. I've heard of them for a couple of years now and have seen a few of their fan units on cars. If I experiment with the electric fan, it will only be one unit. If I can pick up another 20 hp, that would be great, if not, oh well. For those interested, my ECU has been modified along with a few other tidbits. JIMB, stop being arrogant. I provided a link where I retrieved the manufacturer data. Go see for yourself. I then said perhaps it's wrong, I don't know. Now you come after me with something to prove acting like a jerk. I don't need your approval for anything so go abuse someone else. It's really sad that I come here asking a question and get tackled not once, not twice, but three times by the self proclaimed experts. I had no idea that my questions would bring forward this kind of immaturity. WOW, you have really impressed me. Thanks.

OK I do not claim to know half of what most guys do, however with that being said i have talked to a few Porsche Performance shops , and everyone agrees to make more POWER it takes more MONEY..........I wish i could get 40-80 HP for a mear $ 100.00. Truth be told I have looked into Flashing the ECU , cost is around $1500.00 and i could gain 15-20 HP...keyword there being could.Our cars are tuned very well from the factory so, i would suggest talking to people who really know the car. The only suggestion i have is put the car on a diet....Less weight = FREE HP...good luck

Ever notice how these confrontational threads always get started on a friday? TGIF I wish you could get something for nothing, you can't. "If it's good it aint cheap and if it's cheap it ain't good!" That's what a famous racing engine buider used to tell my brother and I when we'd come up with some new 'trick' back in our class racing days. It's so true. The fact is these cars are very highly tuned and it's hard, not impossible, to get more than about 5-15 hp out of all the mods you listed ,combined. Remember with these hp claims it's not cumulative, they have to work in concert. Why do you think race teams spend so much time on the dyno (not BS chassis dynos either) with each new modification AND sytem wide re-adjustments? Really, if it was that easy, everyone would be doing it. The easiest way to go fast is lose wt, both car and driver. It used to amuse me seeing these tricked out, aluminum/magnesium everything cars with some 300# guy driving it, then wonder why they never win. On that note, have a nice weekend, take it easy on Dallas, he's just the messenger, we've all fallen for various bogus claims in the past and learned from it, it's called experience.

I've seen tests of these electric chargers -- they draw more power than they create... Cheap HP gains are few & far between these days, and virtually nonexistent on a n/a Porsche.

Put an AC inverter onto your batter connections and duct tape a serious leaf blower to your air intake.Try it and see what happpens. I would be very surprised if some increase in intake air density was not observed.

Dallas, When you are on this board, just keep in mind that this tends to be a pretty conservative, traditional crowd. There is nothing wrong with this, but it helps to know your audience. I have been flamed in the past for asking straight-line acceleration (1/4 mile) times, so go figure. Give it time, and continued depreciation of 996 values, and you will see the topics of conversation change over the next few years. My prior "fun" car was a 1994 Mazda Rx7 TT that I had owned from new; you'd be amazed how much the forum topics of conversation, and the audience, changed over the 9 years when prices dropped from $40k down to $10-15k. Change happens... some accept it, some get grumpy and call people young punks or not worthy of owning such a car... oh well... I too am skeptical of the "superfan," but would be interested in understanding the current mods you are running to make your car faster... the mod bug is starting to bite at me these days...

Webtool, thanks! You are funny. C4s Surgeon, spoken like an adult, thank you. JIMB, your period will pass, take a pill. 1999porsche911, I'm not defending this company, I only asked if anyone had experience with the product. I see your point on the guarantee but honestly, I can afford to lose $300. It's just not that big of a deal. Don't worry, I'm not claiming my car is faster than yours so we can still be friends. Here's the skinny on my car. EVO claims and displays the dyno sheet on their website, intake and ECU +25 hp No Cats, +8 hp No Exhaust, cup style, +12 hp Total 340 hp-345 hp estimate *.05 = +17 hp ERAM kit (if it works?) This is where my logic came from whether is correct or not. As for the weight, I provided the link where I pulled the manufacturer data from. http://www.flat-6.net/forum/showcar....ar_model_id=27 Weight pulled from car: no mufflers = -60 lbs no cats = 20 lbs no spare = 35 lbs The car is factory GT3 aero with HR lowered springs, RS style lightweight wheels.

Remeber you can't always add each mods HP increase together. You lost alot of bottom end torque with that exhaust. You COULD use some boost and get it back. Good luck.

itradem, thanks. My car is defined above. I sold my C4 and purchased this car not long ago. I ordered many of the parts prior to delivery of the car. The car used to belong to a San Antonio Spur. Anyways, as each part was added, nothing seemed that great unitl I changed the ECU program. Once that happened, everything woke up! The car will shoot to redline almost immediate. Throttle response is incredible by comparison. Regardless of what some believe, this car is much faster than other 911's I've encountered. I can reel 911's in very easily, much like Mustang GT's from before the modifications. In short, all of the parts seemed to work best once the computer was adjusted. It's an amazing ride and I'd highly recommend it.

Dallas, You are right and I am wrong. I misunderstood your logic. Your car most certainly weighs 2820 lbs and has at least 340 hp. Further, I am an arrogant jerk with PMS. Not only that but I'm not very bright. It took me hundreds of hours of dismantling to get my car to 2870 lbs and $20K to stuff a 3.6L X51 into my 99 C2 just to get to 305 RWHP. I can accept all this but, intradem, I can't accept being accused of being part of a "conservative, traditional crowd." Now those are fightin words. Look, I'm way too old to care about your petty little comments and frankly I really don't care what you do with your car. It's your money. Have a good weekend. Jim

interesting on the weight thing..... my 99 c2s manual states 2909 lbs (min weight)

Guys, guys, this ain't worth it. Peace. I think we've all made our points. FWIW I don't think p-cars will ever depreciate/deteriorate down to the ricer level. Just for the record, I'm a 'radical coservative' according to my patients. Jim, you have a wealth of knowledge that you bring to the table, I can tell from your posts. I also come from a serious racing background and can smell BS a mile away! Have a nice weekend all!

Good, I'm glad you've gotten the facts straight! Lighten up, ok. I don't claim to know everything or anything for that matter. I pointed you to the link with the weight information. Did you read it, or does this fall under the "I'm not very bright" comment? I even went further to say perhaps the information is wrong, I didn't write it so get over it. Your response has humored me so "thank you". If you want to be the "JERK with PMS", then fine. If you'd like to joke back and forth, be civil, and have fun, then great. You can choose your path. After all, you claim to be "too old".

Dallas, I don't recall claiming to be an expert. What I did say was that your method for calculating weight was flawed. You can't take the weight in the specs and subtract the weight of the parts you take out of your car. It's just not that easy. Porsche publishes a minimum weight for a model. In the case of a 99 it was 2909. That does not mean that that was the starting weight for your car. It is the weight of the lightest possible 996. Small wheels, small tires, minimal stereo, manual seats, no sunroof, etc. Even at that, it is hard to imagine how they got a 996 to that weight. Some car makers weigh their cars without any fluids which would explain it but I'm pretty sure Porsche leaves them in. So, when you add leather, a stereo, 18 inch wheels, larger tires, sunroof, areo kit or whatever, that weight goes up. I know this not because I'm an expert but because I took a very basic 996 and built it into a club racer. We are allowed to run at the factory published weight of 2910 (PCA rounded up). It has proven to be very, very difficult to get the car below 2900. As I mentioned earlier, I did many things that you would never do to a street car like removing the driver's side window and all of the air bags. Now that was a pretty civil response for someone that has just been called a dumb-*** wouldn't you say? And BTW, I'm not that old.

JimB, Sorry, my comment wasn't meant to be aimed at you... more of a generalization... Cheers!

This is like a thread from the Bimmerforums.com. (One of the reasons I sold the M3). A complete waste of time and energy. And all I did was read it. Ack!! C.

I have a 2000 coupe and did a corner balance recently. My car weight 3,300 lbs!!!! Options on car: Factory aero kit (don't know if this option add or reduce weight) PSM Hi Fi Sound (stupid option, sound worst than a Honda) Sport Seats (now with EVO on driver side) US M030 Fab Speed Exhaust Jim is right. There is no way any 996 weight less than 3,100 lbs. Kam

The concept is about electric powered supercharging. Whether a compressor is powered directly from the engine (supercharging), the exhaust (turbocharging), or from an externally powered compressor, the intake air density is increased and more power can be achieved depending on the compressor size and various other related modifications. The web site seems careful to make relatively modest claims (very small compressor), and most of the technical data and methods seemed OK from a quick glance. They do seem to have had some installation concerns with the MAF on Audi and BMW engines, suggesting specific compressor location. The arrangement only powers the compressor at full throttle, so you may lose some power and mileage under normal operating load, as intake air may spin the turbine wheels. The effeciency of making electricity, and then using this in an electic motor will likely be less than the direct drive of a supercharger, or the power extraction of an exhaust turbine. As the battery appears to be drawn down temporarily, it has a mild hybrid characteristic. I doubt you would do much harm tinkering, but the big dogs have bigger compressors. Big electric motors are heavy. I read that a dragster supercharger (45psi boost) uses some 900HP on a 7200 HP engine.

Kids, what have we learned here today???? Your C2 doesn't weigh under 2900 Your engine doesn't produce 340hp, Mods are not cumlative Little intake fans don't do squat ...class dismissed!

Thanks Chris79SC, I am surprised this post lasted so long. Why don't we just wait till Dallasboat buys it and tries it, he said he didn't mind. Basta

rrys, thanks for the input and seemingly the only respectful answer to my question about the fan. It's amazing to me that most of these responses have been to criticise or insult me. For those of you, that think you're so smart, it's great to be around you all. What a pleasure.

In 2000 there was well known PPBB poster who bought this supercharger intake and made some acceleration tests on his 2.7L Boxster. He came to the conclusions that in fact there was a little gain in accelaration, he couldn�t felt it on a seat on the pants point of view, but after measuring the accelaration times vs mile he observed that with the electric fan on he could go from point A to point B some tens faster. I believe in the end he stated that he would take out the sc intake, due to possible problems on the MAF because those engine were known to be sensible to intake mods. I wouldn�t use such kind of intake, or any other for that matter, these engines are fine tuned from factory. J.Seven

Actually I find the fan sort of interesting. I've taken issue with dallas' weight & HP claims but not the fan. I'm a bit skeptical but would love to see someone try it. I'm more curious about it's ability to pull cooler air from a source further from the heat of the engine. As sensitive as the MAF is in these cars I suspect it will be a problem but we won't know until someone tries it. As for this thread, I always try to avoid these pissy conversations. I'm not sure how I got drawn into this one. Generally the regulars on this board are very helpful but also are quick to point out BS. I think that is very helpful. Obviously dallas has responded with language and attitude more like you would find on the import boards than what is normal here. We/I should have just ignored it and let this thread die quickly. Dallas, this is the last time I will address you. We have a different culture here than you are probably used to in the other boards. Join in and you can learn from these guys and we just might learn a thing or two from you. Act like you have been and you will just be ignored and will eventually be thrown out. We've all seen it happen. Best of luck. You've got a great looking car no matter what it weighs. Jim

JIMB, you are obsessed. You came here yelling at me about a weight claim when I was asking about electric fans. Read your posts (you might want to delete them). You now try to act calm and reasonable but it's all in the threads. I never asked for you to disprove my weight, i then apologized and told you where my source for the numbers came from. We then had another person comment the numbers are in the users manual and back up my original thoughts, go figure. As if that's not enough you continue to follow and harass me. Now you claim you don't know how you got dragged into this? Are you on drugs? FYI, I don't belong to other forums so I'm not sure what you are talking about. I could care less about your culture, you come across like a complete blow hard. Again, I'd suggest reviewing your comments towards me and then stepping back for a while. Three times now you claim to be done with this trhead, perhaps now you will really go away.. That, or just lighten up. I appreciate your comments on how cars can weigh more and it makes sense, thank you. However, my inquiry was about the fan and that's what I'd like to focus on. Not how much my car might actually weigh or the fact that I'm a dope for even suggesting I might try this fan. I don't mind kidding back and forth but some of you take this far too seriously. It is a car, you are on the Internet, take it all wth a grain of salt.

Back to the fan, sorry. OK, I'm going to order this "super fan" and see what happens. I'll have to construct an air intake from my before mentioned parts and perhaps some new ones. Honestly, I half expect this thing to cause problems with my MAF but hopefully not. Again, if it really brings 1 psi of boost and adds HP, great. They show a 996 with a twin blower setup but it looks really ugly. I don't want the current draw of the double unit so I'll stick with the single fan. I'll post my experience as it happens. For those that are skeptical, i am too. However, don't sweat it, it costs you nothing and you'll have the advantage to say "I told you so". JIMB, don't worry. I'm not going to turn your playground into a rice burner page. Now, where's that folgers coffee can, I can make a really mean sounding exhaust with one of those.

Kool Dallas, keep us posted on how it goes. Looking forward to your feedback.

dallas, I caution you due to how fragile the MAF sensor is. Do some research before you start. Let us know what you find. C.
