Why in the hell do you need 39lb injectors with the mods you have?

But yes they will work, after you get a tune.... but thats way to much injector without a blower. All you need is 24# injectors at the MOST.

because i have a vortech w/ intercooler sitting on my table. lol. buy my last few parts before install. Have injectors bov and maf left and im set for install. My original idea of 42# for a good price fell through couldnt get ford racing ones like i originally planned.

I dont like to run injectors over about 80% duty cycle, and IIRC 80% DC for a 39# is around that HP. You can push them farther than that though for sure.

Just like people push 19#ers to 300.. even though they are at 80% at like 260-270. Just a saftey buffer to keep the pulse widths down.

I am running 39# injectors and have no issues. I had to get adapters for them to fit to the wiring harness though.

Are they from a 03-04? I thought you only needed adapters from 05+ injectors.

yea i see your point. as long as i get to 425 i dont think it matters if i have to upgrade later...because later is going to be expensive....everything i have will be at the reliable limit at 425....lol
