Fast 65# ls3 injectors

[DSX]

LS9 injectors move 52.5 lb/hr at 58psi. The problem with a return system is you lose effective fuel pressure under boost. 10psi boost will drop that flow rate to about 47.7 lb/hr because effective flow will go to 48psi. ZR1s make the most of these injectors because they ramp fuel pressure to 88psi which Camaros can't do because of the 58psi mechanical regulator in the system.

If you are running an efficient setup that can make a lot of power with low boost, you can get a lot out of these injectors. If you are just cramming tons of boost through with poor efficiency, the injectors will give up.

well lets put it this way. the car has a cam, long tubes with stock exhaust and cats. tvs2300 and lingenfelter's twin pump fuel system and its not enough. Logs don't lie...most times lol. So i'm pretty sure the car is over 600whp...some how. Doesn't make sense to me but it is what it is. And i'm not pushing alot of boost either. 3.80 pulley on the maggie and stock crank pulley.

cam just seems to be very efficient with where the car is at so far.

A blower cam will really make or break a supercharged setup. It's amazing how big of a difference a cam can make.

to be honest this cam seems better than the one i have in my car.

The injector setting you use in the tune can change what the computer claims the injectors are running at. You can change the injector information to get different scanning results. Doesn't mean your injectors aren't right and you are fighting another problem. A BAP setup right can give great results but don't get greddy with voltage, you'll loose more than you gain....
