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.

 

?????????????
