Is there an injector out there that is bigger than the SVO Green Top 42 but smaller than the Mototron 60 for use in LS2s with the 63.5 IFR Table limit in the LS2 PCM?

None that I really know of I have 39.5 ford cobra injectors in the 05 which works out to roughly 54#'s at 58 psi.

Well that's bigger than the green tops. Same connector and height? Just so happend these would be for a GTO.

Wait. How does a 39.5 work out to be a 54 when green top 42s work out to be a 48.8?

1MEANGTO

They are rated at 30 psi. How do you figure that a green top is only good for 48.8? Let me check my graph I'll get back to you.

1MEANGTO

Wow I never realized they were rated at 40 psi. I feel like a dumbass. I have always just multiplied 42 #'s 156 percent and it's always worked but I look at the gragh's and I'm kinda lost. Ok so at 3 bar (40psi) A svo 39.5 cobra injector is actually rated the same as a 42 green top if that makes any sense. So yes 48.8 would be the correct size from what Im reading. I feel really dumb right now must be time to go to bed.

Anyone else? How are you guys running 60lb injectors? I would like to know. Are there any problems with running these injectors? I am the guy Glenn is trying to tune my GTO for...

1MEANGTO

You can run 60# injectors if your using efilive. I can send you a tune that I have with 60# injectors but its from a vette but the tables are the same.

We are using HPTuners. What is EFIlive? Which injectors are you using? Size, impedance etc?

THere are plenty of people on LS2GTO.COM running them. Have you been there?

1MEANGTO

Why do you need such big injectors? Is in F/I? The vette tune that I have is on E85 and makes around 500 to the tires.
