I'm having SC put in next week an wanted to have gear an stall put in before they tuned it...

Was wondering what y'all were running?
Any info would be appreciated..

What I got: Pretty much stock.. Longtubes, FAST 92 an ported TB. A4 w/ 3:15..
Having A&A SC installed.. Later on plan to do heads cam ect... Wondering if I should do gears an stall with SC install or have gears an stall done with heads cam install? Which one would be more beneficial?
An what gear an stall would be best for what I'm doing?
Thanks Kris

I don't have a SC yet but will be adding an A&A kit soon. I have an A4 with a 3.42 diff and a Yank SS3200 stall. All my research has indicated that it will be a good combo for the SC.

Hope it helps.

I have a Procharger and I am running a YANK 3200 Stall and 3.42 Gears - Just make sure you use a very good tranny cooler -

Here is the one I have on mine:

I have no issues at all, here is a chart to see the difference in ratios and RPM Vs MPH:

Hey thanks for the replys...
I understand an always heard 3.42's but my question being since I have 3.15's now an 3.15 an 3.42 being so close of a gear. Should I change from 3.15 to 3.42 now.. Then when I get heads cam ect. upgrade again from 3.42 to a lower gear again?
Or would be better to stay 3.15 an once I do heads cam upgrade to the lower gear then an only change the gear once?
An the tranny cooler is a must an will be put on..
Thanks for the reply guys..

Stay with the 3.42's with the A4, going lower on our A4's does it no good.

The 3.42's I did over my 3.15's were very noticeable and I love them, I will not ans would not go any lower!

Look at my Sig below and you'll see the stages I went through and I began with my stock 3.15's then went to the 3.42's all the way through!

I am finishing up my STAGE 7 right now

Thanks,Matt

Unless you plan to be on very sticky tires all the time and I dont mean michelins or bridgestones dont do gears. The more power you make the more you are going to spin tires. The more gear you have the more you are going to spin. Stalls really wake up autos and I would do that. Keep your 3.15's.

A4 trans here with the 3:42 gears in her. I did have the 3:15 in my car and can tall a diff to the 3:42 but also would not go lower unless you just want to burn more rubber. Also paddle the gas even more. Robert

kris6868

Very good points.. I see more clearly about why not to go too low of a gear.. Thanks alot..

Madmatt your throwing up some very nice number with a A4.. Very nice car..

I have 3:15 with a stall. I thought about going to 3:42 but all i do now is spin so I question going lower. Maybe if I dragged the car regularly and used slicks but not on the street, that is just based off my driving style though

kris6868

Yeah I'm debating to change the gear now or wait an see how it is with the 3.15. Since I getting a lifetime tune anyways.. But I tried calling the guy installing the system to get his advice but he was out driving a car. I'm not doing any racing with it. I'm just wanting to have a smile put on when I'm driving it..
But I'm am doing the stall an tranny cooler..

I'll throw another angle in.....

When you/they install the SC the whole front of the engine will be apart. That's a VERY GOOD time to install a cam. If you wait till later for the cam all the front has to come off again anyway...... heads I don't think are quite that critical (timing wise).

Honestly, you're going to have so much more power after the install I don't think you'd be able to make a good decision about the gears for 6 months to a year anyway.

Spend your money in a more logical manner first.

im running 3:42s with my A4 and sometimes i wish it was a 3:15 spins too much! and not as good on the hwy! stay 3:15 and a 2800 stall

CamminC5

I would do a cam the same time as the SC for sure. If you really want heads also do them with the SC install, but I would save my money for other parts (like trans upgrades). No point to make all that power and a driveline that won't keep up to it.

kris6868

Yeah I see yalls point.. I guess I'll do the cam as well.. Since it's going to be torn apart. What cam specs are y'all running? If y'all don't mind telling.. I want the most insane cam I can put with a SC.
Thanks for the info guys. Y'all have informed me more then I was expecting..
Thank

I vote for 4.56's.. great for the street...

My 03 A4 Coupe with only Borla catback had the base 2.73 gears. When I had the Procharger and LG LT headers installed, I also had the diff replaced with a new 3.42 from GM.

run a blower cam i like the A&A blower cam!

wish the hell I had my 3;42's back!!!!!!!!!!!!!!!!!!!!!!!!!

fsuforever

I run 3.73 gears & a pro yank extreme 3400 stall converter & its a handful on the street, I can lightem up @ 70mph on 17lbs of boost, pending on how much boost u run would be the determining factOr on which gear , if its low run more gear , if its high run less,btw do as I say not as I do,i tend to take it to tthe extreme

edram454

I swapped out my 2.73 for my 3:42 gear ratio..huge difference. no stall and with these gears you wont need them. all you will do is spin more and tear up more stuff. If I had kept my 2.73 or stepped up to 3:15 them maybe a stall would be in order. also did the cam while the car was apart for the supercharger install. had a custom blower cam installed by HorsePower Sales in Pompano. car dynoed at 525rwhp on a Mustang dyno. I have been told that if I would take it to a dynojet dyno it would dyno about 40hp more on average. car is a beast. when I smash it while doing 40 or so it downshifts into passing gear and all hell breaks loose..tires and all. really too much for street tires. If I were to go with drag radials I would probably lose my transmission and eventually my axles since they have not yet been upgraded. You dont want too much traction unless all your drivetrain has been upgraded. edramos.
