installed HIGH compression pistons OMG

[melfice_mx]

nothing wrong with rocks.. i live in Tj.. i use them.. and my Talon runs mid 11's

That's good. You'll know just how to go about replacing them. Real soon.

But, it will be a fun week.

Hey that hunk of junk is my old motor.

I'm anticipating the dyno.

This whole thread is absolutely pointless because nobody knows how high the compression is. It could be 9:1 or it could be 12:1. Without knowing the actual compression ratio then there is nothing left to discuss. Even if it was 12:1 thats nothing new, people have been running high compression turbo engines for years. Why dont you pull the head off and take some measurements and calcualte the compression ratio then come back and tell us what it is. Maybe then we can have a discussion on "high compression" turbo engines. If they are n/t pistons dont even bother coming back to post because we already know what the result is going to be.

I know you can heat treat steel because the crystal structure changes from BCC to FCC upon heating and under proper cooling conditions you can make it harder or softer. But aluminium doesn't change crystal structure the way steel does, the only way to make aluminium harder and stronger is by alloying it or cold working it. So I'm guessing this shop is full of shit, much the way most shops who claim to do cryo-treating are.

man u try to act like you know what you are talking about, but if you knew anything aluminum can be heated and the bearing caps are heat treated in the head and they use heat treated aluminum for a lot of motocycle and bicycle frames and such.

I wonder if his profile is updated. With all his mods he's only runing 14's for the quarter mile.

This is nonsense...Where do you buy your pot?
Aluminum is heat treatable. T-6 The most common treatment to the most commonly used alloy 6061 means "solution heat treated and artificially aged."
BCC, FCC.. Is that like martensite, cementite, perlite or what phase are you trying to describe?

thanks for the negative points ass wipes

Hey i was just readin some old threads i was in and where the hell are the dyno numbers guess his engine blew up and didnt want to tell anyone?????

I take the whole thread with a grain of salt if he thinks a couple points in compression makes the same difference as 10+ pounds of boost.
