what size injectors?

Ok i know you take the flywheel hp and multiply by..07. Im figuring that the car should had around 500fwhp after a dyno tune. I plan on running a 150 shot at the strip so should this be taken into consideration before i purchase the injectors?

Zex wet kit. Was gonna go with a 150 shot for strip use. The motor when finished should be in the 450-500 fwhp range i just don't wanna sell myself short. 42 lb veno

Re: what size injectors?

A wet kit doesn't use the injectors to add fuel for the nitrous. You size the injectors for the normally aspirated HP. Are you indicating 42# Venom injectors with "42 lb veno"? That would be a mistake. Stick with the proven brands, not the "ricer" brands.

42 #/HR injectors will be fine. Just get good ones.

Re: what size injectors?

I've heard alot of complaints on here about the accel injectors. I found a set of bosch 36# on ebay for 260.00. I'm gonna purchase those because i thought you added the hp u gain from the nitrous also. I should be around or a little under 500 hp.

Although they wouldn't leave much room for hp gains so maybe ill death a little more extensively for bosch 42# injectors

Re: what size injectors?

There's no reason to not get the 42#'s. leave plenty of overhead.
