as some of you will know ,ive been trying to improve on my f7p conversion rwd 5, but i just cant seem to get over the 300bhp mark,maybe im being greedy or to optomistic with what ive got, but it is really bugging me, i have so far played around withe the standard cams (and piper 270 inlet cam), bigger throttle body and recently fitted a bigger pwr chargecooler,
but i just cant seem to make the numbers, what are other members making and running and what inlet/ exhaust manifolds /turbos/and cams are being used to make higher numbers,
my engine so far consits of -
f7p flowed head megane inlets and williams exhaust valves
pwr 6x8 cooler
76mm diameter boost pipes
80mm throttle body
3" exhaust sytem (1m long in total including silencer)
log manifold
gt3071r with .63 exhaust housing
standard f7p cams with no overlap
intend to fit a pressure gauge to the log manifold next week, to measure pressure outputs,or am i wasting my time and efforts, with the fault being somewhere else i.e turbo, dont want to splash out on a set of turbo high lift cams when i probabley could'nt use the extra lift/flow anyway
could it be my log manifold holding me back or turbo spec
would a fabricated equal length manifold be my answer
any thoughts or ideas would be a great help,
