c6 Z
prev setup:

KB intake

present setup

KB intake

when i bought my cam the vendor told me 540 to 550 on my set up and it was all bullsh** i got 520 rwhp by beating the engine on the dyno jet :eek: this is selling business :banghead:

gocha , but will ported tb and intake show hp gain in my set up for the time bieng :cheers:

you know i haven't noticed the intake lobe is small :bigshock: all take your advice and what a disappointment :banghead: and thank you very much :cheers:

yeah could you tell me about the ETP...

all ready done

now thats good guesses ill try check them and i will go 12.3 AFR with 24* timing to see what happens :shrug:

but this set up can reach up to 540~550 im shore safly :rolleyes:

the base line was 446 rwhp , the intake or TB are not ported how ever when we increase the timing we see a lot KR retard :bigshock: :banghead:
