I want to know this: i have stock 550cc injectors,do you think if i add 2 extra 550cc's it would be safe to have my car running at 18 psi of boost with race gas.

My t2 mods are
3inch custom exhaust,hks ssqbov,tilton clutch, cold intake , walbro ,safc, blitz dual sbc,a/f gauge, hks boost gauge,egt gauge,spearco fmic,gtx ported turbo,thanks

 

why not replace the secondary 550's with 720's or 850's? much cheaper than adding more injectors + fuel rail + controller etc.

 

If they put 720s for secondaries how are they controlled. The stock ECU is going to think they are 550s and if they are replaced with 720s then the car will run really rich.

Am I missing something?

 

very true, I take the fuel controller for granted....<sigh>

 

First of all thanks for the replys ,I live in central america and i dont have acces to bigger injectors,also i wasnt planing on using a fuel controler,this is the way i was gonna do it,i was gonna do a custom flange to fit the extra injectors and hook them up with the signal that goes to the secondaries,so when i'm going wot i would had enough gas,
and also controling them with the safc.
This is an experiment dunno if its gonna work what do you think
