The Racetronix kit comes with a Walbro 255 pump and a dedicated wiring harness for the pump....this ensures consistent voltage at the pump.

255 alone will support ~5-550whp
Racetronix kit will support ~6-650whp

 

Where are you getting those numbers from? Not arguing just interested to know.

 

Data collected from customers and the countless cars we have helped tune.

There are cars that have seen more and a few that will run out of pump before then.

 

I didnt realize their kit could support that much...I already have their 255 pump, maybe I'll get the kit incase I run some juice...only think I wonder is if the fuel lines can handle the volume needed?

Stock fuel lines will be fine. I'm supporting 800HP (300-shot) with -6AN lines, same diameter as the stock supply line (3/8"). Rich Krause has run his 800rwHP blower setup on stock fuel lines.

 

Thanks Fred, I was wondering how the stock lines related to -6AN line. You run dual nozzles in that or what?

I have a one-of-a-kind 300HP dry shot. Two NOS fan-jet nozzles in the outlet of a WS6 airbox, no MAF - engine runs speed-density on a MoTeC M48Pro ECU, which is capable of supplying the fuel through 78#/HR injectors running at 58psi. Extremely simple system.

 

I was thinking about going to speed density tuning and losing the MAF, but I've got a lot of reading to do in the tuning section.
