If anyones interested ,the formula for injectors is like this.
say it is a Xlb injector times that by 2.04 then times it by the number of pots for rear wheel hp.
So a 24lb x2.04 = roughly 48 x 6 pots = 288rwhp or about 212rwkw
A set of 29lb 2= roughly 58 x6 pots = 348rwhp or about 250rwkw
Or you can divide the cc by 5 and times it by the number of cylinders again
So at 440cc divided by 5 = 88x 6 = 528 hp or about 400kw .
So a 36lb injector flowing at 370cc you can work it out for yourself.

Cheers Badcooky, I found some similar formulas myself. Quite helpful.

The only other thing Joe is that most tuners rather than extract the last few hp out of a set of maxed injectors wil go a size or 2 up to cover the boom tinkle grind variables dude.
