newbie question. How far has anyone gone with the stock fuel system 08 gsr? Whats the highest hp you can acheive before changing pump or injectors-stock turbo also.Thanks in advance.

 

This is as far as my stock fuel system would take me, afterward I added a few ported parts and needed to upgrade the fuel pump.

 

so its safe to say then-the evo x is good for about 350 whp before you need to upgrade fuel,cams, turbo and stuff like that....450-500 on a stock fuel system and stock turbo isnt happening?:

 

Anyone have stats as to how much hp the stock injectors are good for?Turbo?Fuel pump?

 

Stock turbo/stock injectors/Walbro 255HP:

 

So thats where they max out then-around 360hp?Thanks

 

Yup.

 

wow good to know I'm also a newb in this area

 

Yes good to know when you meet someone claiming to be at 450-500 whp and you ask-you upgraded the fuel system yes?No. Bigger turbo? No. Makes you wonder why people make unrealistic claims with nothing to back it up.

 

does anyone know what kind of airflow rate ie g/s are we looking at when hitting a dyno 360bhp?..
