Default 454 LSX With PRC LS7 CNC Heads!!
Just finally got time to post the LSX chassis dyno results!

98 Trans Am

TSP 454 LSX
PRC LS7 Heads
11.25:1 Compression
LS7R Camshaft
1 7/8" Headers
True Duals
85mm maf!
Stock LS7 Intake!!
PTM 90mm Throttle Body
12 Bolt Gear 3.73
Stock Pulley & Stock Water Pump!

Maybe we'll throw a ported intake & 100mm maf & shoot for the 630rwhp range!!

Very nice M6 or A4? I would have thought you would go for 11.5 or so compression though. What is the spike in the torque curve?

That is extremely nice considering there is some power left on the table. The stock pulley, waterpump, unported intake, relatively* small maf, and throttle body could all be swapped out for some mega power. I'd like to see this thing with a 100mm lid, 100mm maf, 100mm tb, ported intake, underdrive pulley, and EWP. I bet it would make 630-645rwhp.
