ok.. granted this is through a stall and a 12 bolt and cats.... but i really would expect MUCH more out of a 418 and ported L92's.. what am i missing here????
with that kinda CFM on the heads and 10 more cubes than my 408 i would expect nowhere under 540-550 RWHP even through that stall and rear?

i agree completely
the only thing not making sense is the heavily ported cathedral port heads pushing less CFM are putting down WAYYYY more power than these monster rectangle ported new stuff with huge flow numbers... granted this dyno graph has AWESOME power under the curve and solid torque... i just dont understand why the peaks wouldnt be a little higher? not talkin **** in any way shape or form btw TSP so dont get mad at me

this is nearly a 550+ rwhp car through a 6 speed. i think this is an absoulty beautiful thing. i still dont see many cathedral port cars making that kind of power per dollar. so what king of price tag does this combo carry?

520rwhp in a a4 through cats seems pretty damn good to me. At 11:1 the car drives awesome & works really well with a tiny 2800 stall!
