Prob not, but I will ask.

cc306 with valve job and mild head work. New 357 bottom end and looking for the 375+ hp range.

If not how big do I need?

 

I would think around a 36# SVO should be ok. Maybe up to a 42#

 

I got 36# for my CC306 and stock heads. 30# would do fine, 36# leaves growing room for nitrous, bigger cam, better heads etc.

 

If you mean 375 flywheel HP you would be OK (~90% duty cycle)... but I suspect you mean 375 rwHP, putting you at about 435 flywheel HP. The injectors would be required to exceed 100% duty cycle. All these are approximate numbers, based on assumptions regarding the quality of the tune, BSFC, etc.

I'd recommend at least a 32#/HR injector. But if you plan any future increases, something larger than that would make sense.

 

Thanks. Ya I mean 375rwhp. I had dibs on a set and was waiting for a paypal address and the guy decides to sell them to someone else....

If it comes down to it, are the summit FMS injectors the ones that I run at 31.6lb in the computer?

Yeah, the 30lbs SVO's have red tops and actually flow more than 30lbs in our cars because of increased fuel pressure. I'm not sure of the injector constant value, but I think you are very close with your guess. A search would tell you for sure, I remember seeing it on here a few times.

 

Look at racetronix...They have a good selection of injectors and had 32#s on sale for a while...
