High comp

[andrew24]

I have a 06 with exhaust intake and cam how high in comp can I go with pump gas I live in miami fl

[S.A.J]

12:5:1 run that on 93 octane and your good,or 13:5:1 with 50/50 mix of race gas and 93

[andrew24]

What 12:5:1 brand do u recomend and would it be a big diffrence

[Ty's400]

You will experience a more significant difference with a 13.5:1 or higher piston on your application. The 06+ 450's already have 12:1 compression. My preference would be a CP piston.

[andrew24]

I don't have higher than 93 octane here it's hard to get

[S.A.J]

my preferance would also be cp and if you go higher than 13:5:1 id go drg also cp dont make shelf pistons higher than 13:5:1 and drg i believe gets his custom built by cp...and about the diference part on the 06 its like Ty's400 said they already have close to what your wanting to get so idk how big of a diferance you'd feel but everybit counts right? but if you live in miami surely you could get race gas somwhere...look at race shops call around im sure if you live in miami or close to you shld be able to get a hold of some unless things are much dif. there

What's the highest comp on 93

[nracer300]

if u have an aftermarket cam then u can still run pumped gas with a 13.5 to 1 piston

[BlaineKaiser450]

i have a 12.5:1 CP on my 04 and i run it on Shell 91 and it runs great
