416ex piston

[400EX QUADER]

What should I get that will produce the most power and be reliable? JE 10:8:1, Wiseco 11:1 or JE 12:5:1? Also would I have to run full racegas on the 12:5:1 or 1/2?

Anybody?:confused:

with pump gas the JE 10.8:1 with race gas the JE 12.5

[400EX QUADER]

What? You can't use pump gas on the 10:8:1 you have to use half. Do I have to run full racegas on the JE 12:5:1 or 1/2 racegas 1/2 pump? Which would have the most power and be most reliable? Name the power from best to worst.

you can run 93 octane pump gas up to 11:1 compression

My friend had a 416ex with the je 10:8:1 and he had to run 1/2 racegas. Also which piston would u recommend?
Thanx,cory

i heard up to 11:1 was safe on pump,that is why i went iwth the 10.8 piston,if you have access to race gas then the 12.5 but if not then the 10.8 i would stay away from weisco considering i have heard many a bad things about them

I ran my 11:1 on 93 and it ran fine?..

[400EX QUADER]

It probably just depends on the quad.

we run a 10.8:1 416 and a 11:1 426 both on 93 octane. we have tried race gas and noticed no difference drag racing. the dyno might show slight gains here and there, i don't know. they really didn't seem to run cooler either but i guess that is hard to judge.
