Default Off the rail maximum shot?

Anyone have experience spraying a decent sized shot off of the stock fuel rails on a ls1?

Only fuel upgrades are a 255 pump, hot wire kit, and 38lb injectors.

Whats the max people and pulled off the stock rails on their cars?

I have run 150 off the rail with a Nos plate kit (90mm) Car was actually very rich with the stock jetting the kit came with, I have a racetronix pump kit with the hotwire setup, 42 lb injectors

i was able to squeeze a 300 shot off the rail on my TNT F2 kit. Fuel pump (racetronix intake) started to lean it out though (was making 650+HP)

when it was pilled for a 250 hit, the pump and rails kept up safely.

Do you remember how many degrees you had to pull for that?

I have 4 pulled now for a much smaller shot than that.

rule of thumb is 2* for every 50 HP.....thats what I'd go with, then tune the timing back in from there, to be safe.
