Back ground of the car:
I have a 99 Cobra with an 03 Cobra shortblock, Ported/Polish 99 C-heads, SHM Blower cams, comp cams valve springs, Stage 4 steggy, 2.93 upper, 6lb metco lower, SCT BA2400, 60lb injectors, 03 tank and pumps, KB 40 amp Bap, JLT high boost CAI, Billetflow TB and plenum, BBK LT's, catted H-pipe, LFP Dual pass HE, LFP IC resovior, Evenflow Head cooling mod, Canton 10qt oil pan, ARP head studs, V-spec T56, solid rear, 4.30's ect....
Problem:
I took my car to RET for Greg to dynotune it, first off let me say that Greg and his staff are awsome and that there customer is excellent!!!! He is very knowledgable and helpful but I ran into a problem and need extra help/suggestions. With the above mods on 91 octane, 19 degrees of timing and 11.7 A/F across the board I made on 368rwhp/380ish tq. I was expecting low 500's:shrug: My MAF counts are in the 900's and my pumps were pegging, so we know it's getting the fuel/air to make the power, but we can't figure out why it's not making the power. We also verified that it was making boost which it is, in fact it's making 18psi at WOT and dropping slighty to 15-16 after 6k. I need help!! I did a compression test and here are the results, this was done with the motor cold:
Front of engine
145 150
140 140
140 140
140 135
Please provide any ideas, I hope Greg will post up my dyno sheet and numbers.
