Bigger Injectors?

At how much power does someone usually need bigger injectors? I plan on doing an XE 227/233 cam and long tube headers... I was told 360rwhp is about where it will be. Would I need bigger injectors then? If not injectors... what other things do I need to compensate for the power? Other then a 12 Bolt or 9".

Re: Bigger Injectors?

24# injectors are supposed to be good up to around 400rwhp.

You doing heads too? 360rwhp seems a bit high I think if your not assuming you just have the "bolt ons". I would think you would be in the 345 area. Let us know, dont see to many dyno graphs with that cam yet.

Dave from CombinationSports said 380 was done with those mods... 360 is more then likely...

Re: Bigger Injectors?

Id go with a set of 30#'s, just to be safe.Then, you'd be ready for later mods like heads, LT's,etc...Ya have to think ahead sometimes..

Re: Bigger Injectors?

Once they hit more than 80% duty cycle at WOT you should really look in to upgrading. That seems to be about 340-370 RWHP on our cars, everybody's is a little different.
