I was just told by local shops herein Phx and alsoJDM that the gt500 fuel pumps are good for Boost applications Ithink there rated for 700HP FI and 800N/A. The down side of using a BAP is kinda like overclocking your computer. It can lead to early fuel pump failure and BAP failure is possible but not common. That's why I sprung for the JDM GT500 setup. An $800 insurance policy for an engine is well worth it IMO.

 

I have the Kenne Bell BAP and have no problems. My air/fuel ratio stays right in there. I know because I have the AEM gauge.

 

Personally if it was me I would go with the GT500 fuel pump system. I was considering the boost-a-pump, but in the long run the GT500 system better, also if you have a stick you should consider replacing the clutch .

 

Thanks for all the info. The gt500 feul pump equals no worries whereas with the BaP I'd have to really monitor A/F ratio. Whats the hp upper limit for the KB BaP? 450rwhp is my goal.
