Limits of the stock fuel pump??

[2011GT1979]

Has anyone found out what the limits are? I recently ordered a D1SC kit for my car and I am starting to order gauges and injectors and so on. I have read several places where people are making good power on the same set up I am going after, but they are not talking much about the fuel limits.

I just need to know if I need to go to a dual pump set up or maybe to the GT500 pump.

Edit: Shooting for 550 - 600 RWHP on a stock bottom end.

Right about 550 to the tire. Then throw a boost a pump on ther and be good til 650-675.

Is the stock pump a twin or single setup?

You can use the stock pump to just over 600 rwhp with the right size injectors, but it's about done at that point. The stock assembly is a single pump.

Anyone test the limits with the Kenne Bell BAP yet?

He asked the limit, meaning 11.5/11.6 AFR all the way accross without it leaning out to 12.0 A/F plus from 6,200 RPM and up....

You are correct. I posted this question on another forum just for more opinions. Evolutions original post of roughly 550 safely is what many people agree with.

Thanks again guys!!
