Yea i was wondering if all u guys run the 300TT fuel pump?...and how much boost can the stock fuel pump handle til it starts to drop off? cause right now i run 15psi once in awhile with the stock pump still and wondering if i should upgrade asap.

More than 10 psi on a t25 is running the 370cc injectors and the stock ser pump at it's limits.
This is what I have heard.
Good luck!

I ran 14 psi on t3t04e with the stock pump and 370cc , and Sleeper still runs the stock pump with an inline unit on their Black car that puts down 426hp at 26 pounds of boost.

I would't be guessing at what psi the stock fuel pump tops out, because this depends on the type of turbo that you're runnig and the set up that you have on your car. Just to be on the safe side, if you plan on going pass 12psi get a 3000zxtt remanufacturated pump(140.00)or a walbro pump they run for about the same price.

Went a-boostin in my and Ben Moses's car last night. My car with 9.5:1 compression would produce audible detonation at 11psi. Ben's car with 8.3:1 compression wouldn't start to detonate till around 18psi! We were both shocked to see the thing jump to nearly 20psi before we heard any detonation. He has the stock fuel pump, 370cc injectors, and stock DE MAF, as do I. Weird huh?
