Which Gears

Heres a analogy that I really like when you go outside jogging you start to breathe in and out faster and harder. Well the same thing goes for a performance engine. The engine is breathing in and out harder and faster, at a higher rpm. If a high performance engine makes power at a higher rpm, then a higher stall speed torque converter is what you need to put more power to the ground quicker.

Personally I liked my 4.10's in conjunction with my PI 3000 stall. Couldnt catch traction worth a d*** but enjoyed it.

ok, that made sense. thanks!

When I was learning about this stuff that was the only way I could describe it. Now I can go into depth on these things. Man I need another Camaro. I'm selling my converter if your interested. Do you already have gears or not yet?

I've got 3:73 going in there and 3000 stall as well. expecting my car out of the shop next week, I got new ls2 402 stroker motor, AFR225 heads, G5X3 cam, built up A4 tranny, dumped 12k on it...

3.73 should be a good gear ratio for a stroker. Should be nice and balanced goodluck with it. 12k whew

ls2 is a bad boy...and fully built....are you going to throw some funny gas at it.....your setup is what i dream of.....but at 12k is alot of money

well 12k plus 5k spent on pulley, full exhaust, lid+filter, new springs, shocks and subframe connectors. but yeah the ls2 402 is forged, so full bolts on with it = 500rwhp.
with that said I can throw a s/c on it or better yet a twin turbo to go 800rwhp. but I need a 12 bolt first

... ok this is off topic

**stunna-shades** · 02-20-2007, 09:23 PM

i voted for 373's but if you are a six speed and have a 12 bolt or 9 in id say 410's all the way

**import slayer** · 02-22-2007, 02:15 PM

I have an A4 as well and I used to have 3.73's but when I upgraded to a 9 inch I got 4.11 gears and I love them way more than the 3.73. On the highway it is not that much diffrent than 3.73 as far as rpms goes either.

**stunna-shades** · 02-22-2007, 07:42 PM

a giant cam will love love love.(3 loves) 410's also....they go together like peas and carrots..

**guitarjay76** · 03-01-2007, 01:30 PM

Im Sayin You Should Hit Over 170 With The .273s. I've Had Mine Pegged With The Same Gears, K&n, Velocity Stack, Maf&housing, Hypertech 3 And Flowmaster 3" Cat-back Several Times On The Street-- With More To Offer. P.s (shhhhh- I Hear The Boys In Blue Have No Sense Of Humor!!!!)

Hey do you still have converter?

**30th290** · 03-15-2007, 05:41 PM

if you put a 4.10 in a a4 wouldent you have to use od in the quarter

**98 formula ws6** · 03-15-2007, 06:30 PM

So basically you wen through the traps in 2nd gear then?? Sounds about right for a 2.73 auto.

4.10's should help a lot

**Ridinfilthy** · 04-08-2007, 08:11 PM

i would like to know if i put 4.10 in my f-body with 26 in tire and 3400 converter will i hit od or be in fourth at 6k any info would be appreciated!!!

**Hawk241** · 04-26-2007, 08:39 AM

Hey, A4 guys, what are you guys running rpm wise at 60 mph with 3.73's? I have 3.23's now and a set of 3.42's in a box, I know that if I install those, I am at 2,000 rpm at 60.

3:73, A4 built stage 4, 3000 stall running 2600-2700 rpm at 60. I'll double check but I am pretty sure that's where it is, also LS1Edit tuned so shift points are moved a bit.

**Hawk241** · 04-26-2007, 09:06 AM

Woa, thats a jump from where I am at, almost another 1,000 rpms than 3.23's. I know its all about performance etc., but I plan to do a trip or two, like the camaro firebird challange etc., in New Hampshire, I dont want to fill up every two hundred miles..how much top end did you lose?

I checked on this and it is actually 2300 at 60 mi/hr, in some setup less. I got a 402 ls2... on an ls1 I think it would be 2200-2150 at 60mi/hr with 3:73 gears.
