A4 vs. M6 trap speeds What would be the difference in trap speeds between a 3.42 A4 LS1 to a well-driven 3.42 M6 LS1 with equal mods? I'm just wondering exactly how much of the M6's advantage in trap speeds comes from their gears.
i would guess 1.5-2 mph.
a stick car doesn't have the advantage because of the gear difference, it has the advantage because an automatic eats more hp. stick cars have a mechanical connection, whereas the autos rely on fluid being pumped to actuate the ****. and pumping that fluid is what eats hp.

I relaize that, thats why I wanted to know how much of the difference should be accounted to the transmission and how much to the gears.
gears won't show a great deal of variance until you start talking cars that trap over 110 mph. there is a gray area between stock and 110 that gears really don't do much except lower your 60.

mine gained a little too. 104 to 110 mph. The stall is good for more than 330 ft. shift extension is everything.
But to add something to this threads question.
I ran my auto with stock 3:23 gears for 5 years,and resently switched to 3:42 gears and found nothing at all for a gain.
Hope that sheds some light for ya. Too small a change to really matter.

Verdad Gallardo with the addition of a stall and NOTHING else you gained 6 mph?
going from 104 to 110 is like gaining 20 rwhp.
i haven't noticed any gain from 50-110. ..but i was using my gf's 6 spd car as a reference. maybe the track will tell otherwise.

Yup, but a stall changes all of that.

Actually gaining 6 mph is like gaining 55 to 60 hp

I gained a full second and gained 6 mph, how is that less efficient? Maybe when you talk about regular street driving, there I'd agree. It's less efficient in saving gas but saving gas is the least concern in a horsepower junkie's mind.
I dynoed 313rwhp and 331rwtq, I don't think that I lost much HP with this stall and those numbers are locked numbers.
The only tuning I had done was to the transmission: shift points, torque management.
Oh and my raceweight was/is 3505 with me in it 1/2 tank of gas. The only thing I removed was the spare and jack.

In the same weekend drove it to work Friday and in town Friday night, then raced all day saturday,took my son to a Pistons game in Detroit Sunday and found no E/T or mph inmprovment at the track,but the gas mileage is a nice little bonus though.
I need to get my car tuned,only has a Predator tune. Not a downloaded 1 either.
