So how much HP an you make with only an intank 255 pump? Just wondering how much the stock fuel lines and rails will hold.

 

500-600hp if not more with big enough injectors and a good 255lph pump (or two pumps would be ideal tho to keep up fuel pressure). But yea stock rails and lines etc can handle quite a bit...

 

a friend of mine is making over 700 hp with a turbo. he has twin pumps, stock lines and rails, with 60lb injectors.

 

there ya go, thats just one more example of alot of guys making that kind of power...i love LS1's =)

 

Thanks guys. I guess I need to look into atwin pump setup. I'm working on a friends LT car that we are putting a YSI on. should make around 700-750rwhp. I want to sump it, run some fuel lines and make it an E-85 car. but I think he doesn't want to spend the money on it right now.

 

our twin pump setup can make 1000rwhp without issue and we have several guys running it on E-85.
