The Trans Am guy can drive and all his shifts were dead on as were mine...

The only info I got from him on the cam is that it is a blower cam...Not sure of the specs beyond that...

50whp difference gets brought back to 1 CL due to 4.10 gears...

Well first off are you auto or m6? Second what are your rpms at say 80mph? There's a way to tell, hopefully your speedos correct...

Nice runs, very close. I don't think gears can make up for a 50whp difference though, something seems off.

Tough to compare A4 to M6...

The Trans Am owner is a capable driver...He didn't miss a shift or blip the rev limiter...

We went from a 35mph roll which is ideal for my 2nd gear...3 honks...I was the one honking so I may have gotten a slight jump because of that, but nothing to get excited about.

I wasn't powershifting and I don't believe he was either, but even my granny shift is pretty damn fast.

I'm M6...

I believe my RPM at 80mph are around 2000 or so when in 6th gear...I haven't looked to confirm, but I've got a long drive tonight so if I get an opening I'll check...

I have a Superchips tuner which has been set to 4.10 gears which means my speedometer should be correct...

This race was 35mph to the top of my 4th gear...If I hit 5th, the Trans Am would still be in 4th and would start to walk away from there...So this wasn't a topend run...This was a quick 35mph to maybe 118mph...

That's not a huge surprise, from 35mph you've got a pretty big advantage on him whether he's in 1st or 2nd(he's either got to lug 2nd or spin through 1st). Looked like he was pulling away pretty hard at the end. Good race either way.

Somewhere around 1800 I think...Again, I haven't really paid attention to that, but I'll try and take a look tonight and I'll confirm what it's at later on this evening....


The car already had the gears installed when I bought it...

I average 21 mpg per tank full which includes mixed driving between freeway and around town......and I have a heavy foot

I took a 4.5 hour trip from western Washington over to eastern Washington last year....I averaged 29 mpg for the trip with the A/C cranked the whole way.

Thanks...

He started in 2nd I believe...

The race was on my terms...He has more whp/wtq by a good amount obviously...35mph roll in 2nd is right in the middle of my powerband...We stopped at the top of my 4th because if I hit 5th he really would have walked away...

I should also mention that my 345whp/360wtq is somewhat of an estimate...

I dyno'd 334whp/350wtq on a dynojet earlier this year...

I added my MTi Lid as I climbed on the dyno and I really don't think it had any affect on my dyno run...

Since then I have also cut out all the extra baffling and crap for the free ram air mod which I felt a big difference on the topend of my powerband...

A Hypertech 160 t-stat was recently added and the fan temps were lowered to match...



Based off those things I have guesstimated that I'm now at 345whp/360wtq...

Kind of a ricer thing to do, but I don't feel like dropping $$$ for another dyno pull until I get a cam and LT's...

i don't think they make a HUGE difference...

i raced a guy with 3.73s and the same boltons as me.

both autos

both 3600 stalls i believe

he only got me by a car or less, if i remember right and i got 2.73s

eh idk if i believe gears give you as much as you think, but i guess this is just my experience

Hmm I have 4.11's in mine and at 80 i'm at 2200-2300 roughly, you may have different gears in yours.
