Default What size injectors

I'm putting a d1 Procharger on my 2006 gto, kooks 3" exhaust, big cam, meth injection, already has upgraded fuel system from a STS turbo. Does anyone know what size injectors I should go with?

Hard to say without you telling us gasoline or E85 and what RWHP you are going for. I can tell you my non-referenced 103# injectors are at 55% duty cycle at 750rwhp with pump gas and meth injection. They were 95% duty cycle when I ran E85 at that level.

High test pump gas, not sure what e85 is and I'm shooting for 600 to 650 Rwhp. I currently have 60 # seimeins left over from my Turbo

I agree, your 60 pounds injectors will work just fine provided you have a good fuel pump. Bob

I ran 60's on my D1SC, I was at 114% with 14 lbs boost, base was 43 PSI
prob could have upped the base pressure, but I got 120's, prob 80's would have been fine
you may be fine with 60's, as every combo is diff
injectors are not cheap, so having to buy another set sucks, lol

Since he's not using it, he won't need to upgrade ****. On an unrelated grammar **** note, is "you" that much harder to type?

Plus he's adding meth into the mix. His 60's will be fine as the meth will also be adding octane.
