At what HP does the stock fuel pump run out of juice? Same thing with the fpr, at what point (probably not a specific HP) do you need an adjustable fpr?

I've been researching a lot and I want to know every detail before I buy any parts.

 

Does anyone have a dyno comparison of running a quality high flow cat vs running a test pipe? I'm mostly interested in a supercharged application, but would be interested to see it on any FI car.

Further, is it a problem to run a 70mm HFC on a stock header & exhaust, in expectation that those parts will eventually be upgraded? Or should I stick with a 63mm?

 

1500 ish? Maybe check the evolution forums, they sell more of those then we do. May even sell it faster there.

Stock pump won't support much. Pumps aren't crazy expensive no need to not upgrade it.

 

Hey guys,

The piping kit that I have for my turbo has a flange for the FV model, however on the Greddy website it says that the BOV is intended to be used in the "100-420HP" range. I'm pretty sure that by the time I'm done with this build and get a tune on the car, I'll be sitting around ~475WHP, so I'm not sure if that 420HP limitation will be a problem...

Let me know what you guys think. I'm not sure if there's any other companies that make BOVs (or adapters) that can work with the FV flange, or if the FV will be fine as is.

 

That's kind of what I was thinking too, but I've seen multiple guys complaining about losing fuel pressure over 6k rpms (or around there) and if I can eliminate one more potential problem that would be awesome.

I assumed I'd have to upgrade to hit my 350whp goal anyway, I was just curious.

I hit right around 345whp with the 06+ returnless setup so you'd probably be ok with the better return/fpr system, but like has been mentioned here before, swapping a pump is a lot cheaper and less frustrating than replacing it later and going back to the tuner. I know I regret not just swapping it out in the beginning.

 

You will need a pump for 350hp.

 

Trackforged turbo screens are back in stock so I can finally put one on my car. I think my turbo will thank me lol

 

 

Im going e85 soon. What is the proper fueling I will need for it? I currently have stock lines, rail, and fpr with id1000cc injectors and aeromotive 340 pump with stock wiring.

Im looking into id2000cc injectors, Possiably the aem 320 e85 pump, aem fpr, and the haltech flex fuel sensor. Im looking at making 600-700whp. I have a built motor.
