Halon, I can use my stock FPR with bigger injectors and fuel pump? I thought you had to adjust the fuel pressure so your car doesnt run to lean or to rich?


Yes you can. You don't need to even consider upgrading it until maybe you go to a 255 pump. And even then, you can still get away with the stocker.

You really won't be adjust the fuel pressure at all, you'll use DSMLink for all your fuel adjustments.

If you're lucky. When I bought my car it has a 255 and stock FPr, but it was overrunning it and pushing fuel past the diaphram. Tried two others, and had the same issue so I just bought an Aeromotive adjustable FPR.

Your stock FPR will be fine for your goals, it will have no trouble supporting a Walbro 190 or Evo fuel pump.

What pump would you rather have? Which is easier to install?


And when you guys replace your evo 560's you wanna sell a set to me?

Bert,
I made 239.1hp on pump, 294hp on E85. 880s did the job for me.

For E85 with the 880s did you do a dual pump, or single warblo pump?

And I could get 880s and using dsm link tell them to flow less so they would appear to be 660's right?

If somebody has affordable 1000+cc injectors around I'd be happy to give up my evo injectors as well. I'm no longer bound by MAF correction limits :)

I'd go with the Evo pump simply because its cheaper and its a factory OEM part so it will probably last longer than the aftermarket Walbro (this is just a guess).

I'll be listing my injectors for sale as soon as I remove them so watch the classifieds in case I forget to PM you!

Single pump would be fine, where the hell are you reading about twin pumps?

I am not trying to be mean, but if you are reading about something try to take in all of it.
