Default The Dyno results are in.....

1992 A4
119k on the clock.

SLP Claw Intake
Corsa Catback
Cat Elems

Run conditions 85.8 Deg 28.6 HG Humidity 19%

Max Power = 272.53 HP
Max Torque = 303.57



I was pleased. I was hoping to run between 260-280, 272 will work just fine

Now I need to dig those damn headers out of the closet and get them on.

1992 is a LT1 right. so that dyno was 272 rear wheel horses right. what dose GM say the engine is putting out, they just do engine horse power so your RWHP is the right way.

A stock '92 LT1 is rated at 300 HP and 330 lb/ft TQ from factory so these numbers are inline with the factory rating.

That was a good run! Now, I think an LT4 top end would set you up quite nicely!

Its a LT1 , factory rated at 300hp.

And yes , a LT4 package is in the works

Here is a pic of the dyno sheet. I notice that at 4200 RPM things drop a bit then pick right back up. I don't know if its anything to be worried about, just kinda caught my eye.

The dip is likely due to the torque convertor doing a "forced lock" on the dyno.. No biggy.
