I have the 5177 kit and have been running the 100 shot which I hear is 85rwhp but I want to step it up to a 125rwhp shot. All I have done to my 00 vette is a full exhuast (Lg longtubes, -cats, x-pipe, slp loudmouth) and zip-tie mod. I wanted to know what you guy think, will my stock y2k injectors and fuel pump hold it? and I belive I want dual .043's for 125rwhp??

Thanks.

 

anyone know??

 

Get bigger injectors, and a fuel pressure gauge. Spray it on the dyno and look at your fuel pressure. If it doesn't drop too much and you can get the AF ratio right should be no problems.

I'd at least get bigger injectors.

 

your fine man spray away, as long as you dont add a cam or other major mods

 

I made 480rwhp with the 5177 and stock 28lb'ers, however, I was going lean, not too bad, but telling me I was outa injector.

Well I'm going to take Robert56's advise that he gave me and try a 100rwhp shot and log all the reading and go from there.

 

watch your fuel pressure too.

 

my 2000 fbod was the only year with 26.6# injectors stock. Not sure what the vettes had. I wouldn't go over a 75shot dry with 26#ers
