wow, you have a 255hp fuel pump, where can I get one of those :p

Nice, setup. when do you start making full boost?

Thanks.

Full boost is from 4500 up. It takes it a bit longer to make 23psi though so it didnt hit 23 till 5500.

The lag isnt bad, just cant punch it at 2500 and expect anything.

Wow 22psi pump?? 93 or 94 octane I'm presuming. No detonation? I'm not excessively familiar with the max psi with you pump you can do, but I thought it was more like 17psi. Thanks for any info. Nice setup man!!

Stock Internals, Stock Headgasket, Stock Cams.
93 octane pump gas from Shell.

22psi is alot, but I really think it all comes down to tuning. I dont think wouldnt want to push more then that on stock internals though. 17 is alot safer then 22 that is for sure.

Stock head gasket! at 23 psi! you're crazy. BTW the joke about the 255hp fuel pump was in reference to your sig in case you didn't know wtf I was talking about...

haha, yea i got the 255hp joke. I didnt even think about it when i put that in my sig. Maybe I should change it to 255 high pressure.

I drive it daily at 19-20psi.

Yes, it is a Walbro 255lph High-Pressure model.

They make 2 models of the 255lph. The High-pressure flows alot more at high fuel pressures. And the fuel pressure goes up with boost on a turbo car. It is also a good idea on Nitrous cars using a dry shot because those kits send nitrous to the FPR to raise the fuel pressure.

The normal model of the 255 is better for NA cars.

Interestingly, the 190lph flows more at high fuel pressures then the low pressure 255lph.
