I recently had my Corvette dyno-tuned for performance and I thought I'd share a few videos from the experience. For those who have never seen a C5 on the dyno, the operator brought my vehicle to 150 mph and then released the accelerator and let it coast to a stop. It was quite an adventure to watch, (and to hear! Those Corsa’s are LOUD!)

Anyway, here are three pulls on the dyno while tuning my ’04 Coupe with a Blackwing intake, Corsa Pace Car (Sport) exhaust, and NGK TR55 spark plugs:

UPDATE 01/24/13: BTW, I have an A4 with 3.15:1 Performance Axle.

What were the results?

Dyno pulls are always cool to watch.

I went from 308 rwhp @ 5350 rpm to 324 rwhp @ 5350 rpm.
Torque numbers were from 318 rw lb-ft @ 4600 rpm to 346 rw lb-ft @ 4050 rpm.

Nice

Was the 308 completely stock from an earlier dyno test, and the increase to 324 due to the Blackwing, Corsa, and plugs?

Just curious since my FRC has a Blackwing and Borla and I was thinking it might be similar.

Thanks

Was the 308 to 324 just from the intake, exhaust, and spark plugs? Or were those the final numbers after tuning?

I brought the car in with the intake and exhaust mounted (and no preliminary numbers, unfortunately.) They did a baseline pull (video #1) then installed the plugs and did an intermediate pull (video #2, no data available) and did the final pull after the tune (video #3.)

If that's all the mods you have on the car, that's a nice increase. Mine has the same mods but it is an A4 so I would expect mine to have lower numbers.

s'noJob

Don't expect that because mine's an automatic trans as well.

I do, however, have the 3.15:1 performance axle, if that makes a difference.

So the plugs and tune made the 16 rwhp change.

Very nice gains and worthwhile getting the tune after minor mods.

Thanks.

I have the same mods on my C5 as you with the A4 and 3:15 rear. Just wondering what a set of long tube headers w/o cats would add to those dyno numbers ? Anyone know ? Thanks

Cutlassmaster

My 99 A4 with 3.15's has these mods:
XSPower headers with cats and full 3" cat-back XS system
Vararam
Fast 90 with LS2 TB
Crane 1.8 roller rockers
Catch can
Lew tune
Making 371HP and 383TQ. First dyno I had vararam and Diablo tune and was at 308HP and 335TQ. I am happy with everything currently.

These dyno videos are so kool.
They make me want to dyno mine. I did a mail order tune to go with my mods. No regrets but one day in the future I would like to put mine on a machine, if for no other reason but to film it. :-)

s'noJob

I don't plan on getting headers any time soon, but I hear they can add a significant amount of rwhp.
