How Much Power Are You Making @ The Wheels?!!?
I guess I could include my old F-body #'s.. The setup was a little different than what I have now, but still a FMS408ci with a 246/250 LSA 112. It put down an incredible 564rwhp/518rwtq thru cutouts and I think 542rwhp with cutouts closed thru SLP Dual Dual's. As of now I dont think no other 408ci or below hydraulic cam'd F-body or Y-body has dyno'd higher. That setup was created over a year ago and the motor is still running strong in my C5 with several nitrous runs and has seen over 900rwtq on the spray. I keep the oil changed and I pop the valve covers every 6000 miles to make sure all is well under there. I dont have a oil burning problem and my oil pressure is always good. Hell I am waiting for FMS to advertise their FMS402's soon... I might want to get my 90lbs back.

Dynoed today, 4 pulls, 1st pull stock tune superchips program removed, mods include MTI P/P throttle body, Custom made intake, TR MAF ends, Custom Magnaflow exhaust ='s 314.9HP/326.7TQ, with Jeff Creech's help in tuning after the 4th pull I got 337.7HP/346.8TQ not bad for a basically stock ls1, No headers no internals whatsoever, Not even a full bolt-on car by any means.
Not to shabby I must say. Motor must have been built on a Wednesday
