Save for a standalone....I was running the srp pistons and eagle rods also. Boosting at 12psi w/ 12:1 fmu and airtek fuel pump w/440 cc injectors. Blew the motor again. You should really invest in a standalone. Thats wut my ass is saving up for now. Now i have to go thru yet another rebuild..

If you go to the RC website, they have the formulas to walk you through the math to determine what size injectors you will need.

The advice to get a programmable system is good at that boost level. You will not only make more power, but it will be safer. One of the problems with using larger than stock injectors and a rising-rate fmu is that if you significantly increase the injector size (which you will have to do at 12 psi) you will be so rich at idle that you will wash out the rings.
