Well finally broke down to day and put my 1997 Sonoma on the dyno. With the great Help from the guys at Delk Performance in Lebanon, TN. here is what I ended up with.
Mods first: 1997 Sonoma 4.3 "W" VIN
K & N FIPK Gen. II Intake
HPP3
2 Chamber Flowmaster
And some tranny mods that don't effect HP
And here we are.
RWHP = 170.56 @ 4200 RPM
RWTQ = 222.33 @ 3200 RPM
We also hooked it to a air/fuel mixture meter and I'm actually running a little rich. I figured I was running real lean do to the HPP3 and opening up the intake and exhaust. Oh well so much for theories.
Not as good as I would have liked but I'm happy with it. Now the question is forced induction on the 4.3 or a 5.7 vortec swap.
Well Later,
Verne
