.....On gravana web site, Rk Sport fuel pressure riser. Just wondering if anyone knows about this product and how it exactly works and if it's safe.

 

yes it is safe i would wait for stage kits first (new injectors) then buy this may pull a extra 10 hp off of stage 2

 

Basically all it does I believe is raise the fuel pressure, allowing more fuel to get to the engine, in turn this will make more power, you could do it now, however the best gains will be noticed after the stage kits.....

 

Well I already have headers, cold air intake, full magnaflow exhaust, and Psi-fi (now revitup boost kit) boost kit/2.8 pulley,power pack. I have'nt dynoed yet but I'm probably pushin 265-270whp. I think I'll go ahead and try it.

 

Without bigger injectors, you're not making more than 250whp !

 

ive seen dyno sheets of a turbo 2.2 ecotec that used the same injectors as u guys that made 243.2 WHP with a 11.2 a/f ratio so i dunno bout that.

 

on the returnless fuel system the 2.0ss/sc uses , its a useless part

 

yeah. I figured that it was useless after looking on my car
