Ive got a rotrex supercharged engine running dta.
compression ratio 9.3.1
boost 10.4 psi
rpm redline 7700
7 port head
jenvey throttle bodies
med rockers 1.5-1
the engine is good but never has it produced the power i wanted.
im after 140 bhp at the wheels it shows 115 at the wheels.
didn't massively bother until yesterday when my pals 8 port mini came past me down the straight without to much hassle.
now im questioning the set up.
its been on the dyno numerous times
cam
ignition
the cam is a special grind kent
inlet duration 287
lift 7.2mm
exhaust duration 223
lift 6.31 mm
does this seem right
how much advance should i use on it.
?????????????
