Do i need to run a fpr on my setup, i will run crome, and 550's? i have heard the stock on is a go, but i just want to make sure...
thanks

 

Depends on your power goals.............

 

Considering you have 550s and crome, I'd say 300ish?

Stocker is fine, adjustable is nice to have though.

 

power goal is only 260 nuthin that crazy.. only reason for the 550 is that i got them at a good price

 

You'll be fine. You can get a little b&m regulator for like $20 tho. Don't see why you wouldn't do that.........GL.

 

No real need for one. I ran my stock one for a long time until I maxed out my injectors, then I bought an adjustable for a few bucks to raise fuel pressure and lower injector duty cycle until I finished my new setup with larger injectors. I had no problems whatsoever though with the stock one and with 550's and a goal of only 260 whp or so, you will be fine.

I would venture to say you could probably make it into the 340ish whp range with stock fuel pressure on 550's.

 

Not trying to thread jack considering that the question has been answered and all, but i was just wondering where you guys are getting your fuel pressure regulators from, as far as the B&M and such, everywhere i look they are kinda expensive... I look in the classifieds here and dont have much luck.

My friend owns a shop and he sold me one for $20. That must be somewhere near cost for them. You can get them on ebay for $30-$40 I think..........not sure though.

up to 350-400 ish you are fine with the stocker.

 

Im running some bigger injectors like 720cc's with the stock FPR on my B18C. I think my injectors are at 51% duty cycle and Im making over 300whp. Id say the stock is good to go
