I just found out I still have the stock fuel pump. It has an LT1 with a 70mm turbo/T56. I'll have rearend out this weekend and figure now is the time to do it.
I was looking at the Aeromotive Stealth pump. What do you guy's think? Also am I going to have to run all new lines ( Stock lines are still in it) and if so, what do you guys recommend. Car is a little over 500 hp. Future plans are a 383 stroker and more boost.
Thank you in advance.

 

Stock TPI pump will power 500 HP

 

Walbro 255 would support 500hp but Im going to run a walbro 455 intank. I rather have more than i need for a pump than running a smaller pump very hard.

 

Check out this website: http://www.autoperformanceengineerin...l/fpspecs.html

According to the equation on their FAQ page the Walbro High Pressure pump at 13.5 VDC and 60 psi will support 700+ HP. That is the pump in my car at this time and what I am going to continue to use in my conversion.

 

Thanks guys. I do plan to add more power later. Have any of you used the Aeromotive 340 Stealth pump?

 

I used the 340 pump, my best advice is to RUN AWAY FROM AEROMOTIVE 340's

Twin 255's are cheap, reliable and more than enough for your build. Boost reference the second via hobbs or run it continuous. Both methods work fine
