Dyno Numbers
We had a dyno day at a local shop this morning. My bone stock LT1 95 A4 coupe turned 262.3 RWHP and 285.3 RT. I was quite pleased with this for stock. That equates to 327.8 HP at the flywheel and 356.6 lb/ft of torque.

To get more realistic results I would stick with 18% drivetrain loss for autos and 15% for manuals. That would put you at 309.5 FHP and 336.7 lb/tq. Not bad numbers, but certainly within factory spec.

By the way I dynoed my '94 LT1 6-speed today and with only a Corsa cat-back exhaust it made 281 RWH and 309 lb/ft TQ.

It's crazy how much wieght plays a factor. It's really obvious when you do the math, in regards to wieght/torque. My old GTO has more horses but dam this vette just "feels" so much faster. I am sure they would be close in the 1/4.

Had my 92 A4 spun saturday.
Layed down 272 HP and 303 FtLbs
Only mods: SLP Claw intake, Corsa Catback , and cat elems.
So all these numbers seem to be inline. The 94 is about 10hp higher , most likely due to the manual tranny.
I have 119000 miles on mine too
And for what its worth, the shop owner also told me that they see upwards of 20% loss in Auto equiped vettes.
