Hi All,

What kind of power will Gray injectors max out at?
Running on a T34.63
Also what is the max amount of boost grays and the turbo above could handle and what kind of boost is producing what power?

Say two bar of boost as this is what most with these injectors are running.

Interested to know the next step in power and what it can achieve

Thanks

Mark

 

Grey injectors are flat out at 450bhp.
The t34.63 will do just over 400bhp but not for long.

When talking boost you need to know what it holds at 6500/7000rpm.

You can run the big boost in the mid range, something like 2.2 bar is what we use. And by 6500 drop to 1.8/9bar and will give a gen 400bhp. With a ported head and inlet cam.

The .48 is a better exhaust housing IMO for the road. Alot more punchy and only a 20bhp and a few hundred rpm sacrafise up the top.

 

What would it be at around 2 bar? Would that be safer for the turbo? Would you recommend a dump valve for that?
