How much power/TRQ is the STOCK FUEL SYSTEM good for
I know it depends on the tune whether or not you are running rich or lean and a variety of other factors,
But with a stock fuel system, Stock fuel pumps, Clean Filter and Stock Injectors, how much power can you get out of the engine?
Without Nitrous or course!

I need to know also
I'm trying to decide on the 50 #'s or leave the 42#'s and if i do this injector swap ,will the stock pumps be sucked dry and need changing as well?
OR just leave the stock system alone and pray nothing bad happens
I'm scared..... Magnum,stock block,16#'s, Full bassani w/cats
Help

Rob,
When running a wet nitrous system, you are only verifying that the stock lines and pump are big enough... The injectors dont get taxed with a Wet-System...
I made 466 / 605 SAE with no problems on a completly stock fuel system (No Boost-a-pump and no nitrous)
I think right around there is the cutoff point.. As soon as I got into the 495-500rwhp area I could never get enough fuel to it with the stock system...
Upgraded my pumps/injectors/lines/filter/rails/regulator and havent had a problem since.

Just as Dale said........stock pumps/injectors are fine for the 450/460 rwhp.
After that your just playing Russian Roulette. I have since upgraded to the 55lb injectors and the BIG MOUTH 255 gph pumps.
What Rob doesn't realize is he is dumping fuel around the injectors with his wet kit. And he is correct...he is dumping fuel

I think 500/600 is still plenty do-able with the stock fuel system
Nitrous or no Nitrous, HP IS HP and mine seems to dump plenty of fuel at those numbers

But you going way past 460/570 like 500/600 thats quite a difference for injector sizes
All I want and need for now is just 450-460hp and 550-570tq with the stock fuel system
Currently have 404/505 w/ eaton 2.80 upper and 4# lower
With Magnum 2.70 and 4# lower and 100 mm idler pulleys ready for self install im just trying to get into the 11's with a daily driver on 93 octane and a safe A/F ratio
I dont care if its an 11.999999999
It will be done before Oct 2 for the Ford VS GM smackdown!!!!

I would suggest 100% race gas when you dyno. If you lean out you will have safety cushion.
Be careful... Be smart.

i am running a 6lber with my magnum and the same other mods you have talked about. sept 18th sal is comingto norcal to dyno tune some trucks, mine included. i have contacted psp on this exact topic and he said i could go either way. he also said that he had tested a ported apten with a 8lber and it was starting to run short.
lets keep this topic on the boards
