What safest hp on pump gas for my fully built darton sleeves cp pistions Manley tuff turbo rods.fully built head dual springs has precision 6262 t4 1000th precision injectors Walbro 400 fuel pump ?

 

Sounds like the motor should be able to handle whatever the 6262 can produce.

 

Keyword pump gas.

What compression ratio is the motor?

I really think staying at or under 500whp on pump gas is a safe/smart move for most typical built setups. Unless we are talking pump E85.

 

9-5-1 and pump I would prefer. WHAT would e85 get me

 

Your fuel setup would hold you back from maxing out that turbo on e85.

No need to set a number, throw it on the dyno and see what it does.

 

Agreed with E85 and that fuel system you would get about 500 out of it.

It's a 9.5:1 motor so that's a little more forgiving on the need for good fuel.

Where are u getting it tuned? Your tuner's comfort with pump gas limits is what u need to be more worried about right now.

 

didn't even see the words pump gas LOL..If its 91 oct. I would say under 500 if you're using E85 your fuel setup is the limit..
