...it's  an old system it has 7 pots for the rev range and a pot 
to set up the on time at WOT and a master mix pot,  so if the 4 
injectors can't supply enough I'll add a 5th injector.

Still building that ;-).......map sensor input controlling the duty 
cycle of the injector.....

RX7 700cfm (I think) intercooler

nope, it's good 'cause I'm hoping that you guys & gals will pick up 
any stupid ideas I have ;-)

Great book got it a couple of months ago from amonzon.com great 
service as well.

Wanting to run 10 - 20 psi on pump gas not proper fuel.... the gas in 
the new unleaded is shit if it was in the states it would be banned, 
47% airomatics  =-( full of benzine now ......I'd rather have the 
lead .....is it true that in America all fuel pumps must have 
extractors on the nozzel to suck the fumes away??
 
Cheers
