996 turbo kit or supercharger kit

With 315 hp being non competitive on the street at this point I've been taking a serious look into this: http://www.tpcracing.com/products/TP...CT-Conversion/ a) has anyone had experiences with after-market turbo on a 996 and if so, good/bad? b) what's the difference between a supercharger kit and a turbo kit? c) would either kit in b) above be too stressful for my engine causing it to prematurely fail or can the engine handle the extra boost? 520 hp ...

Sorry but non competitive on the street? You dont need to be competitive on the street... Apologies for the flame, but not knowing the answer to question b suggests 315HP is more than enough for you for now.

A modified car is never as reliable as stock. There is always a trade off, The boost levels are relatively low so lag shouldn't be too bad but there is always some lag. Looks like full boost dosen't hit until about 4,000 rpm. Finding someone that can do repairs on a modified car is iffy sometimes also. At $10,000 for the kit I would sell current car put that $10,000 plus the cost of install on top of it and buy a car that was a turbo from the factory.

This had been discussed many, MANY, MANY times already. Do a search. If you don't want to read all the crap. The short answer is sell your car, buy a 996 Turbo. Want more, and all the reasons, do a search.

Do you honestly think that some guys in a garage know better than 10 years of research from a team of PhD's with a budget consisting of millions of dollars from Porsche? If so, go buy their turbo/supercharger... The ONLY thing I would mess with, is perhaps mufflers...just for the sound and no other reason.

+1. Not sure what you mean by street competition... Started on the wrong foot. If you want to have fun, may I suggest participating in DE events (PCA, BMW, etc.). With a few minor modifications, you will see that your car can actually be very competitive and keep up with much higher HP cars. Straight line power is not the only factor. Cornering and handling is more important. In any case, the biggest mod is behind the wheel... Once you are sure you have reached its limit, you may choose revisit the Supercharging vs. Turbo issues (which is still an interesting topic). FM

A) Unfortunently you won't find much of that going on here. I'am still new to the Porsche forums but there's no where near as many people doing serious hp mods as people would do in the for example bmw forums B) If your asking this question forget about any aftermarket turbo Porsche. You'll reget it big time. Get yourself a little car like a Jetta vr6 and turbo that. Build a kit yourself and familiarize yourself with turbo cars. You'll gain more then 300whp and youll kill your bank account far less. Right now your not ready.. Sorry. Then again if you really got that cash then go for it.. Make sure you put up a build thread to motivate others. C) Making more power in anything, any way, any how will cause more stress. It's just the way it is. Boosting a car that came na from 300 to 500hp is a lot and you WILL break things because you WILL want to push it and DON'T kid yourself and say your going to baby it everywhere

sell your car and buy a turbo, will cost the same and it will be RELIABLE !

I agree with the others for big power buy a turbo to start. I did mods and enjoy the car more, its quicker and handles way better and is 10x more fun to drive. If you want to win on the streets you should get a new Mustang, S/C it and have a 10 sec car. Porsches are not about winning on the street, the track though is where they shine, brightly.

The turbo kit is not too much for your engine to handle. We recommend running the car at 4 to 6 psi with the boost controller. We have several cars with this system and they all run great and very strong.

Just to clarify on the difference between turbo charger and super charger: I wasn't asking from a technical perspective but moreso from a "in what situations/driving conditions/scenarios is a super charger the better tool and when is a turbo the better tool?" perspective. The track is great but 95% of the time, the challenges occur either at a stoplight or on the highway, not the track and the "course" isn't going to have many turns but a straight shot for the most part

There are as many answers to this question as their are turbo/supercharger options. Generally speaking, a supercharger is going to give you "instant" power, more low end torque and a smoother power curve whereas a turbo will offer more horsepower higher in the power band and will have a more aggressive curve. With that said, you can make a turbo or supercharger behave in either manner based on the size of the turbine/compressor/pulley/etc. you choose.

Show you are a real man by declining those challenges. You have nothing to prove and are only endangering yourself, others, and your car.

Quotes source post: 9473225

I've had both (and nitrous too) on many, many cars that I've owned and raced (drag and road course). For the street (and occasional track), I always preferred the instant power of a positive displacement supercharger. The Turbo is more efficient and will always give you more HP and higher trap/top end speed but, it really depends on your goal. Mike

+1 These two quotes kinda sum it up to me. I spent quite a bit of $ on my motor modding it up short of boosting it and it never made me feel it was worth it for the return feeling in the seat for power. As far as making it more exciting to drive with the money I spent.. oh ya. My Porsche came alive for putting a smile on my face, every corner put a grin on my face. the get up and go isn't horrible but compared to all the American cars I've had over the years supercharged, turboed, nitrous etc. ... ya its going to leave you wanting more. It comes done to what you want. Its your car, make it what you want. that's what I'm doing with mine.. and I'm really changing mine up, more then any other I've seen on this forum lol mod on brother

So.. for $10K, sell your 996 and buy a 996 turbo. But.. what if you find a NIB turbo kit for $5K. Is the smart money still on buying the factory-turboed 911? I kinda like the idea of a "sleeper" 911.. and with RWD, not AWD.

A 5K kit is NOT going to make more power ,, just wont. Sleeper 911? Now there's two words I would not have put together.. The reason they put AWD on the turbos was to keep them from looping I prefer the launch that sticks to smoking the tires off.. Especially since tires that can handle the side load our cars produce can approach 2K a set.. YMMV

No one ever thinks these things out thoroughly, improved braking comes first.

turbocharging an m96 will definitely improve its "breaking" potential

Here's a link to the kit, which is $10K and claims 420ish horsepower to the wheels, which is obviously a huge jump over the 275ish that the NA 996s put down. https://www.tpcracing.com/product/tp...-4s-turbo-kit/ Sure, spending $10K plus several grand for install on a 996 probably isn't a sound financial decision, but what if one were to come across a kit that someone had bought but never used, and it was available for half of that $10K? I like the idea of 420rwhp in a RWD platform--AWD is all well and good for some people, but I prefer managing wheelspin with my right foot, not letting the front tires do the work. AWD "keeps Turbos from looping"??! LOL, good one! There are family sedans that are quicker than 996s nowadays. So yeah, a Carrera that makes more power than a Turbo would definitely be a sleeper. If you start with a confirmed-healthy M96, I feel like it would have at least somewhat of a chance of making 400+hp without grenading itself. And.. if it does go boom, then have the rebuild done to be able to handle the boost.

Wow! Maybe it's because of my age, but I really don't care about beating family sedans. Sure, there are quicker cars now that can beat a 20 year old sports car. I read on Petrolicious about one new car that can do 0-60 in 1.9 seconds. That is amazing...but who really cares? That is beyond human skill to drive. And so, there will always be people poorer than me and richer than me. I don't care. I am totally comfortable with my life and my 996. And spending $10K to add 120 HP? Engine was not designed for that and will not last long. I'm out for longevity so I can continue to enjoy my 996 as long as possible. Here's my 2 cents...

Just seems like $10k is a lot of money to spend on a risk. Motor swap is more appealing to me. with my motor swap if the motor blows I can pick up another motor from a junk yard for $300, rebuild it for $2k and i'm done. if you boost the 3.4.. rebuild is insane cost and if you add making it stronger to handle the boost that just blew your motor.. makes my exhaust clench just thinking bout it lol. Just seems like a money pit to boost that motor...swap it if you want the hp

Portland international,, come out of turn 12 in a turbo and punch it,, you'll hit the left hand rail,, then the right hand guard rail after the right hand turn backwards.. The AWD cars don't do that.. High HP, Rear wheel drive and a slight camber change.. Excitement exceeds acceptable limits. Sometimes guys get lucky and they manage to keep it spinning and it slides outward.. You do realize the rebuild cost on these is basically 15 to 20K??? It can be done cheaper.. if your good and can DIY and do the research.. What family sedans do 170+ Stock ?? and sub 5 seconds 0-60,, That cost less than about $80K I'm trying to think of one.. I'm not really in the modern car loop these days.. Note I'm just chatting here,, its all a philosophical debate.. If ya like the idea go for it and please post up the videos, it oughta be impressive..

Chrysler 300SRT is one that comes to mind...Had an 06 and I really miss that car! But as other have said the m96 is not the platform that can handle forced induction in stock form. LNE can tell you all about it.

Quotes source post: 16468185

You know what else doesn't do that? Cars driven by people whose brains understand how traction and the throttle need to be modulated. LOL The turbo kit listed above claims it only puts 4.5 psi into the motor. That seems pretty mild. So far I haven't come across any threads about anyone doing forced induction on an M96, much less blowing up one of them. In the ~$50K range, here are a few: Kia Stinger GT. Audi S4. Audi RS3. Charger SRT8. Not that a family sedan is the benchmark against which the 911 should be compared, just saying that the bar is continuously being raised as far as straight-line performance goes. Anyway, this isn't something serious at this point. I just came across someone selling a never-installed turbo kit for a good bit less than retail, and figured it might be fun to do. (Haven't gotten a reply from the supposed seller, though.) Although, first thing's first.. I need to get anything else that's amiss sorted out before considering jumping into the deep end of the pool.

I would stop and think long and hard before taking an engine with the M96’s reputation and taking it from a normally aspirated configuration and adding an aftermarket blower or turbo……………. There are many reasons Porsche developed and entirely different engine to run with a turbo………..all of which you are likely to discover if you go this route

I ran VF Engineering's supercharger kit for 5 years (2013-2018) and approx. 3000 miles. DIY Install Boost was capped at 5.5 psi. No problems until my AOS failed and car ran lean. After that I heard a knock and decided to do a DIY elective rebuild from 3.4 to 3.8L. I was expecting to see bore scoring, but after tearing everything down, the only culprit I could attribute it to was worn rod bearings. I'm not an expert, and I haven't posted photos online of the disassembly yet, but maybe there was more to it. For anyone that wants to add a SC to their setup, DM me, as mine is up for sale. (I need to pay for those LN Nickies, Carillo Rods, JE Pistons, IMS Solution, Hoffman Heads!)

Hey!! Scott here from Fabspeed, I've dealt with many of these packages in the past. It really boils down to how far you want to go and at what sacrifice. I have heard a lot of horror stories on converting an NA vehicle to forced induction. In my opinion (biased of course) add some bolt on upgrades like exhaust, intake, and tuning. While yes, you will not add 100+ WHP but you will save substantial $$ and have a new found love for your car. We have some killer options for your car, from air intake systems, to completely bolt on exhaust upgrades. Take a look at a few of the options and feel free to PM me for forum pricing!

So you claim 77 hp gain with all the mods installed? Seems very optimistic to be honest. I'd say that up to 30 with all listed mods would fair.

TPC did the install on my 2000 millenium edition 996 almost 12 years ago and 20.000 km with no problem. I don't track my car so i don't know full potential on race track but its blast to drive on street . I think it's worth every penny i spend on turbo.

I forget to tell you Guys TPC did the dayno it was 420 hp at the wheel,

Quotes source post: 16473666

Was this in reference to my post? If so, nope. That is referred to as "stacking" horsepower. I would have to agree with you, these bolt on's would add around 30-33 whp! You Tube

Apparently forced induction on NA 996s is less uncommon than I thought. There's a FB group about it: https://www.facebook.com/groups/supe...ef=group_cover The supercharger kit is $9K and should be good for low 400s at the wheels on a 3.6. https://vfengineering.com/products/s...11-carrera-996 I am thinking very strongly about doing that kit once I've got the car paid off.

Quotes source post: 16352990

This is a REALLY old topic, but I have a 997.1 with the VF supercharger, and it rips. It's currently undergoing some drivability issues, but unrelated to the supercharger. Also you know you still pull at lights if the time is right, 8 years later or not.

I made 385 at the wheels on a dynojet dyno with a 3.8, so I think VFs' numbers are probably a little high even though they're using engine dyno numbers. Mine might benefit from some tweaking of the tune, but I don't think there's 50 more horse in there, at least not at 6lb. Additionally I have the full Fabspeed exhaust with 200 cell cats and headers. No other power adders or mods to the engine.
