My search didn't show me what I'm looking for.

Does anyone have dyno numbers for a bone stock 2002-2004 Corvette A4?

 

M6 I dynoed 307/317. You figure add in 10 or so hp for ls6 intake and take a little out for A4, and you should be around 300ish rwhp/tq

 

about 280 is what i saw one at mti dyno straight from bill heard chevrolet

 

280-305 is what I've seen.

 

They will make about the same as a LS1 f body hi 200's low 300's maybe a little less becasue of the IRS robs a little HP..it really bums out the vette owners..chevy underrated the f body cars 2 stoke the vette owners egos

 

Trigger Creep,
That is a sweet looking GTA there. How many miles, how long have you had it, and any mods?

 

The only mod doesn't show, the TPI airfoil. Its original, except for battery, water pump and I'm on the 2nd set of Gatorbacks at 44k miles. I bought it new in Dec 1989 in Daytona Beach, my 1st new car purchase. Its had just one repair, a power antenna relay. Thanks for the interest!

 

Good Lord that is an absolutely beautiful GTA.

I wish I kept my 86 T/A....I like the hardtop on yours.

WOW.

 

My 98 A4 vert dynoe'd 278rwhp/294rtrq, completely stock. Not very exciting :-) I would expect about 307rwhp/315rtrq since your PCM and intake are better to start with. Mine achieved those with just a Blackwing and PCM tuning...

regards,
Luis

 

My Z28 with only a lid & K&N dynoed
305/329

My m6 did 309rwhp/328rwtq with 1200 miles on the odometer.
