Boost level on just a pump?

[NeOzz1]

I know i can run 16 tops stock so how much can i run with a pump?

16 maybe 17. Don't take chances, it's never worth it. Get injectors.

 

[NeOzz1]

well how much can i run on injectors and pump with my stock turbo?

No more than 18-19

I don't know if I believe it but road race engineering claims that the stock injectors will handle 400 hp. I would suggest not turning up the boost past 14 pounds without a pump. I run 18 pounds on my stock injectors and ported 14b without much problem, never hit fuel cut or anything like that.

Are you asking how much boost a stock 14b turbo is capable of producing effieciently? I seen a guy on here with dyno sheets proving what he said. Which was that turning up the boost to 21 pounds on his 14b he gained like 11 hp from 18 pounds. Now I know alot of people would argue that 14bs can't produce 21 pounds of boost effeciently but he had the freaking dyno sheets to prove it what can I say.

Yeah, but therein lies the problem.

If you're spinning the 14B fast enough to create 20lbs of boost, it's very unlikely the turbo will last very long.

You'll be spinning it way faster than the fluid bearing was designed to spin. The bearing will fail, and the turbo will be toast.

Personally, I'm not quite sure that's worth 11HP.
