Default Fuel system upgrade, Twin Pumps or Single

I have #36lb inj and stock pump. About to tune with E-85 and put a Wet kit on with a 200 shot for #'s and 150 on the street. I did some searching and found this kit and pump/gasket kit.

(Racetronix C5LS1-FPK2 (with Walbro 255) pump assembly w/ wire harness. www.texas-speed.com/

AC Delco G4 gasket kit. Includes new bolts. Do NOT re-use old gasket. www.rockauto.com


Or should I just go with a KB boost a pump ?

But will this be enough fuel for pushing 600-700 rwhp? I run around 480rwhp just N/A atm. Or will I have to run a twin setup? Thanks
-Josh

the racetronix 255lph pump, wire harness, and a boost-a-pump should work... you will probably need injectors too... I'm about to procharge mine and I will be running all of the above with 60lb mototron injectors... I'm looking for about 650rwhp and from what I have gathered this setup should hold it to 700rwhp

You're looking at the wrong part number. Check C5LS1-FPK2

Click "Fuel", then "Fuel Accessories"

Upgrading the injectors is a sound idea also neutron82. but It will be mainly street driven without using N20 would driveability be an issue with such large injectors that are way more than my NA motor need.
