Walbro pump
I have installed two of these kits on my cars. As you will see, Racetronix maintains that this kit (with hotwire) can support up to 600RWHP. I have one in a 500 wheel NA setup and another that is coupled with a T-rex BAP in a Procharged car that is 546 wheel and both handle those power levels just fine.
