Fueling & Injection - f99 racetronix fuel pump without hotwire ?

So how much hp can a racetronix f99 fuel pump support without the hotwire kit? They say 600hp+, but is that with or without the hotwire kit?

Also are there install instructions for the hotwire kit? I can't seem to find any...

I have the Racetronix 255 lph fuel pump & Hot wire kit on my 98 Camaro.
The kit is good for approx. 550-600 H.P. on a Normally aspirated engine with the Hot wire kit. Use the Hot wire kit because the the 255 walbro fuel pump that comes with the kit puts a greater demand on the stock electrical system.( Pulls more amps ). The Hot wire kit is a High Quality Harness for your fuel pump electrical Circuit. It is the correct way to do your fuel pump upgrade.
The Hot wire kit uses larger diameter wire with an inline fuse & it includes a Heavy Duty Relay. The Hotwire Harness kit is really the way to go.
You should inquire Lonnie at Lonnies Performance. He is a Sponser here on LS1 tech. He is a Racetronix / Walbro supplier & he builds custom in tank systems good for 1000 HP
