What's everyone's thoughts on the limits of the stock fuel pump? I'm just curious, cuz this thing seems to take a lot!!! I haven't gotten a chance to throw my racetronix pump in yet, and the stocker is handling my motor (374 cubes w/ big fms hydraulic roller n20 cam and stg 2.5 tea heads) plus tnt 100 shot with no problems whatsoever! I have no inline pump, no nothing, I just can't believe it's handling it!!! I put the car on a dyno last week, and laid down 560 rwhp on the 100 shot thru a turbo 400 and 12-bolt!!! And that dyno is known for being low (we'll find out saturday, hittin up a diff dyno to get some a/f readings)!!
I just wanted to see if anyone else is having luck like this with the stocker, hehe!

I was wondering the same thing. I have a stock motor with a 150 dry on it and was considering going to a 200 wet. I upgraded the pump to a Racetronix 255 and now going down the track my FPSS shuts down at about 100-110 MPH. I need to put a gauge on it to see what the pressures at. The stock never shut off on me.
