Hello all.

I have a A4 C5, and decided to put in a TC and some 3.42's. After doing some research, I went with a 3500. After 2 weeks, I find it way too loose. I like the fact that I can spin the tires anywhere up to 30mph, but part throttle response was not to my liking.

I would like to spin the tries from a stop without power braking, and from a slow roll. But, I would like much better throttle response. I am thinking of going to the 2800-3000 range with a higher STR. I never go to the track, and want to keep street tires on it.

So, I have to find a happy medium between 3500 and 1600. Any advise would be appreciated.


Thanks,

AZC5

What converter did you get? And what was the STR. Going smaller will really cut into your SE. You wont find a huge difference in a 3000stall when it comes to slipping. You will get used to the sluggish feeling.Any converter is worth having but its a Huge mod so go big or stay at home. Get i shift kit if you dont already and give your 3500 alittle longer.

With a 3500 stall, your response should be great. What you discribe is torque converter slipage That is from like normal take offs and just driving around , like normally. If you have 342s and a 3500stall and your part throttle response is not good you may have another problem. Out the hole that thing should rip. Did you adjust your computer for the gear change and the shift points for the converter.My Advice on better throttle response would be to step on the pedal harder , or go back to stock.

I say go back to stock it sounds like youd be happier

Sounds like 4.10s would suit your purposes. They should create even more tire spin and tighten up the converter. Either that, or a 3000 stall with a 3.0 STR. I don't know if Yank makes those for the C5s, though.

I also have a C5, I had an ST3500 with 3.73 gears this combo was very responsive and there was not a whole lot of looseness. It sounds like you might have the Yank SY3500, this converter has a low STR (1.65) unlike the ST3500 that I had. This would account for the converter feeling a bit loose, either swap that converter for a 3500 with a high STR (2.5 or more) or go to 3.73 gears, this will tighten things up.

AZC5

Yes it is a sy3500 with the lower str. I am thinking of Yanks 3000 C5 2.0str. Or Maybe the Pro Torque 2800 stall. I would go with a PI, but I hear that their stalls are all 400rpm off.

I think I need to be at 2800 with a 2.0 or higher str.

Thanks,

I have the TCI SF3000/2.2 and I like it well enough,
despite some early problems. I think it's probably
smoother than the 3500/2.5, but you probably ought
to learn to "love the one you're with" or at least give
it a couple of months. Your driving habits will adjust
and you may find you like it too much to go back.

That converter is good for street racing. It hooks alittle better but feels alittle loose

I think 3.73's would help you out a lot, I was originally going to go with the SY3500 with 3.42's, but finally decided on going with 3.73's after hearing stories about how it may feel too loose for my liking. Very happy with my current setup. Good Luck

I think installing 4.10 coupled to a 3500 stall (must have at least a 2.7 STR) would be disasterous (sp), not only for hookup but for the stock rearend as well.

I enjoy that loose feeling you describe and don't let that "poor part throttle response" fool you! If you did go to the track with your stock converter hitting each gear hard and pulling all the time, then with your 3500 you'd see that the 3500 get's you to the end of the track quicker. All that banging into gears and pulling is with less torque than the 3500 applies - just more constant. It's an illusion, I felt the same until I got used to my first real stall converter. Just hit the gas and get the rpms up in the sweet spot - you'll have response
On the other hand, if you truely don't care about improved e.t. and just are concerned about the "feeling" - you might want to do what you said first - get a 2800 with 2.5 str or go back to stock.
My opinion..

nevermind, forgot your had a C5

How bout a ST3500? It should be considerbly tighter than the SY3500

quickWS6

He said he liked tire spin and didn't visit the track often. This is a C5 with IRS, not an F-body with a 10-bolt.

Also, this will limit his converter choice. I have not seen SS series converters for C5s.

why do you want to spin the tires? the sy helps you get a maximum launch w/o wheel spin.

Wheel spin = HP going up in smoke.

The SY3500 is actually a very nice converter for the street. There are a few things to do to eat up some of that looseness though. The 3.42s were definitely not the right choice for this converter. The 3.73s work quite nicely when combined with a tranny shift kit.

Remember, loosness is simply a question of foot control and working with your brain to ignore sound of the RPMs rolling up in your ears. You're body will get back in sync soon. It took me about 5 days to get comfortable with this combo but driving it daily on the street becomes just as easy as when you first drove off of the lot.

This little combo cuts 1.6s on motor and 1.48s on a 100 shot. So it's all about foot control.

Just this weekend I put an FLP level 5 and PI Vigilante 3000 in my C5. I seriously was not happy with the revving and not going anywhere thing. From what I hear, the 400rpm difference makes it like a 3400 stall. It revs like a tow truck in traffic. The soccer moms think we're racing and their minivan is winning. Fortunately I had already toned the exhaust down a bit by going from GHLs to Z06 Ti, since heads/cam are loud. I called Mitch at FLP, and he said to give it a couple hundred miles and to program the shift to 0sec above 250ft/lb torque.

The C5 is procharged, and has a 8.7CR forged motor with stage 2 heads and cam, so before the TC it was already softer than stock in traffic.

Having said all that, the weather cleared and I finally had a few chances to nail the throttle. The car scares me again. I'm running 295s, and have to run something with meat. On dry freeway I broke loose several times at 70mph and once at 80mph today. Now that'll get your attention. Once it bites though, meaning in the right gear with the right throttle, the thing flat hauls.

Um, for fun maybe? He doesn't go to the track. There aren't too many things that I enjoy more then seeing smoke come off the back tires from a 30 punch.

Even on the street, when I nail it I want to hook. I enjoy the g's of acceleration, not burning up my tires.

Thanks to the movies and TV, I know some enjoy the smoke, but some don't realize that wheelspin costs them performance.
