Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

When I was driving a Ford Focus one of the first things to do was to stick a underdrive pulley on it. Course with most 2.0 l and smaller engines that aren't charged this a common mod. Have to say it did help with throttle lag especially when the A/C was on. Is this something folks do regularly do on N/A 3.6 engines? See that they are available but I see more folks doing LWFW (yep..had that on the Focus too. That went on before the blower did.) than pulleys. Course, given that I haven't had a ticket yet in the 911 why am I looking to make it quicker?

POST 2Original post

Ford....focus...why did you give it up for a Porsche??? Sounds like it was hot...

POST 3Original post

Try these guys for a custom crank pulley; they will make whatever you want cheap: http://www.aspracing.com/index.html I got a pulley custom made for $200 for my Vortech SC from them, so should be roughly the same.

POST 4 / ORIGINAL POSTEROriginal post

You are a riot....not. It was hot. I have all confidence that a blown ZX3 could smoke most 996 C2/4 in a 1/4. I crossed it and dragged it here in NC. Took the blower off and drove it as my daily for a while. Kept it as a 4th car until my wife decided that 2 cars per person was too many. So I actually traded it in when I bought my 996. 155 whp in a econobox is dangerous on the street. Broke the heart of many a Mustang driver in a red light challenge. Growing up here in the south I gravitated more towards drag racing. Didn't really get into road cars until a friend gave me a spot on his rally team as a backup driver. So in answer to your question, I gave it up because at 40 I can afford to buy what I want. Of course, I could buy what I wanted when I bought the Focus too. I wanted a street racer so I bought one.

POST 5 / ORIGINAL POSTEROriginal post

Back to our regular scheduled post... I know they are available. Just wonder if anyone has put one on a 996 3.6? And if so, have they seen any noticeable improvement? "Leave it alone" my wife says from the other room. "Why didn't you just keep the Focus too if you wanted something to blow up?"

Underdrive pulley will barely make your car faster - maybe 3HP - if that. Most people that get one are track junkies, and it is used to keep the power steering pump from overworking and boiling the fluid. The only real benefit is for the track. IIRC, requires power tools to install as you have to cut off part of the engine block for it to fit. Oh, and you will have low AC charging voltage if you get one. In any event, Mantis, Tarett, and Raby both make them. The Tarett one comes with the tensioning tool. Raby will hook you up with anything you need as well - give him a call for the real guru answers. -td

I am fairly sure Marlon's comments were not intended to make you upset, and I am also fairly certain that your comment was over the line. I would suggest easing up a bit there - not every reply is going to answer every question, and a little poking here and there is for the most part meant as good humor only...

POST 11Original post

Quotes source post: 6689554

That's one of the more satisfying feelings when you have a car that everyone underestimates. I had an old VW GTi like that. It didn't look like much but I had the engine built up to deliver performance. The Porsche is expected to be fast so no one is surprised when it performs well. But a "lowly" economy car can surprise quite a few when set up the right way.

POST 12 / ORIGINAL POSTEROriginal post

After the first comment where I obviously didn't find his comments funny he shot back another lame comment. Maybe he didn't mean to annoy me, but he did and I expressed such. He chose to poke the bear again. As far as my comment being over the line. I assure you it was a kind version of what I normal reserve for folks who seem more than willing to chime in with useless, punk comments but no helpful information. I understand and appreciate your peacemaking. But if he takes offense, let him be a man and say so.

POST 13 / ORIGINAL POSTEROriginal post

Quotes source post: 6690617

Actually I have seen quite a few folks act surprised that a 911 can get off the line. My son hangs out with a bunch of drag strip kids back home and the other week I shot down a few of them at the track with my 996. But it did make me want my old Torino drag car back.

POST 14Original post

Tommy, Just don't snap an axle trying to get a good launch. Did that one last winter trying to better a mid 12. Went home on a flatbed. argh.

POST 15 / ORIGINAL POSTEROriginal post

Paul You a C2 or C4? I babied it a bit. I was actually trying to get the wheels to spin more but I guess the newness of my Sumitomo's made that a challenge. Plus they had just scrubbed down the track the day before. (Dude flipped and rolled a Z28 body full on dragster about 4 runs later. 5th time the car had been launched. $100k down the drain. My son called me the next day and said a buddy of his had picked up the chute and they were going to try hook it up to a pickup truck. My son already has a broken foot so hopefully he won't be on the bloody thing.) I think getting the HP in the 400 range would be key. Then a pair of 18x11 rears. Run some big ole fat 335/30ZR18 rubber in the back and I am guessing 12's will come easy.

That is a personal attack. Those dont fly too well around here.

POST 18Original post

Tommy, I have a 1999 C2, LSD with a 3.6 motor. I don't usually do the drag thing just went out to keep some folks company and ended up taking three passes. Had 315 Hoosiers on the back. They bite... too much in my case on my last run. What was your speed at the end of the quarter? I think mine was 115 or so.

996s were fast for their era. Now coming up on 10 years old, lots of cars have way more horsepower and faster 0-60 and trap speeds. The 996 is still a great car for road or the track, but to keep ahead of the "economy car" curve you still need to drop money into it. The days of 300 HP being a lot have started to slip away. -td

TD.. The 996 is going the replace the E36 a great handling momentum car

POST 22Original post

Tommy - this is a fun place with mostly hard-working and hard-playing adults, best if one works on witty and cerebral comebacks, not 'cheesey-easy' ones. How do you think that makes folks in Wisconsin feel man!? BTW: Is a cheesehead better than being a 'cornhead'???

Quotes source post: 6691060

HAHA!!!! That is a good time ya got there, very close to what I've gotten in the '87. Man, I need a smaller turbo for more boost low down.

POST 26Original post

Cory, Your 1/4 mile speed is sky high, so you must really be having traction problems. I think you make it all back in the last have. What is your 1/8 speed? I was at 92. With grippy tires and a good launch I think you would kill it !

POST 27Original post

Cory I never asked were you running slicks? Hows the rebuild coming?

POST 28Original post

Quotes source posts: 6691691, 6691725

No traction problems, just almost no boost in first and second with a 7:1 or lower compression engine doesnt make for much of any torque. 3rd, well thats a whole different story! I think I did 92 also, that is about when I hit the top of 2nd or bottom of 3rd. The problem resides in my full T-60 compressor/0.85 A/R turbo. It is way too big for my tiny 3.3L motor! I would like to run a smaller A/R but keep the T-60 compressor wheel for those huge peaky hp numbers but hopefully gain some boost lower than 5500RPM in 1st.. No slicks, not needed as I said to Paul. I should get the low-end built in July but the top end, I wont have the money yet, too much going on.....

POST 29Original post

Quotes source post: 6691094

That's true but with any Porsche you have the reputation of being a fast car. My 944 only had 208 horsepower but due to the name on the back everyone believed it was a supercar. Only those who really know the brand knew otherwise. As for the days of a 300 HP car slipping away - well that probably was the case but I think the environmental movement will probably put a cap on the majority of high horsepower cars so 300 horses will still be enough to be competitive on the streets.
