I have a s10 with a l31 I swapped in now I have a whipple charger I want to add and just picked up a marine intake yesterday and need some help with the buld. what size injectors to run? what plugs to run? planning to water intercoller later after I get the truck running with the whipple. is water/meth injection a good thing to run till then? if so where should I put the nozzle? the unit has the 3" pulley so I be running 6lbs. should I get a 2 bar map sensor?

 

If you want to log boost, you need a 2 bar map. To build a VE for boost, you need the 2 bar MAP.

For a low boost build, something between like 45-50lb/hr injectors should be enough to cover you on regular pump gas.

 

I plan to get a smaller pulley and get 10 lbs of boost later.

 

after it gets running and I work out all the bugs I plan to find a smaller pulley and run 10 lbs of boost.

 

the whipple is in the s10 engine bay.

 

the blower was hitting the stock brake master so I changed it out for a smaller one but the stock intake tube still hit so I am fabbing up a new intake tube.
