My ZVH made 230 bhp at 11 psi orso without a fifth injector....

Could be raised to about 14 psi saifely as for the fuel so i was told by the dyno operator.

Have to mention i have forged pistons so don't know what standard can cope with but thouhgt 14 psi would be safe...

Just what You want....

For real power EFI is the way..


Ohh hehehe..Jeroentje RS beat me to it... he's talking about my engine....:P
