saw these on another forum.  i have another block chillin here.  time for some ls rods and some of these

[92CXyD]

why p07's

[ApexSilver06MR]

ultra low compression for super high boost. 

[92CXyD]

yeah but I keep find those more expensive than vitaras.

[zestyskater69]

Just curious what honda engine are the p07's out of? On the other forum did the op get any numbers with those pistons in & how's reliability so far?

Wouldn't be bad with rebushed LS rods if you can find them for cheap

[d112crzy]

You probably couldn't get more than 300 out those.

The vitaras being used in everyones builds are semi forged. That is why they can handle lots of power, not because they're low compression.

I partially disagree.  The vitaras (with stock length rods) low compression is what makes the D's significantly less likely to knock, along with the added benifit of making the combustion chamber a more efficient shape. Yes, they are stout, but thats not the main reason they work so well.

[d112crzy]

I don't think the low compression is the main reason, but it does help substantially. This is not to say that a higher compression ratio is better. I do agree that a cr of around 8:1 is optimal for the small bore, but anything lower is just kind of pointless and will just cause shitty driveability off boost.

[ApexSilver06MR]

Anyone driving a 7.5:1 d out of boost needs to grow some nuts

true. 

my single slam is at 8.6:1

Mine is at 8.0:1  ;D

[Foowee]

If you got some p07's already and can get a groove cut in the wristpin hole for spiral locks or c-clips I say rock 'em.  

It's just that vitaras are so damn cost effective.  $125 for a set w/rings ready to go onto aftermarket rods.  By the time you buy a set of po7's n get the groove cut I'm sure you'll have exceeded $125...  but if you got some free ones n access to a lathe, use em like cardinal uses boy pussy...

I was under the impression that they were just cast really well. Not "semi forged". And I was also under the impression that the Vitaras had strong ass ringlands, something stock Honda pistons do not...

[Joseph Davis]

VX pistons have about the same CR as Vitaras, but the ring land isn't as thick.  Just don't run out of octane (ping) and they should make good power.

They're "semi-forged" according to FJT.

[92CXyD]

I think they are what is called High-Density Cast where there is a vacuum on the mold when the metal poured.

[shogun]

we have done ls rods and p07, on a budget build pistons and rings were 85 dollars if i remember correctly, i just hope i can get 15 psi out of a he351cw without any issues, motor was going in today ill post videos once i get them

[Joseph Davis]

Pressure has nothing to do with the density of the solid or liquid phases.

[DmC]

It's 25% compression 25% combustion chamber shape 50% the thicker ringlands that make vitara's hold up so well. 

[Joseph Davis]

It's 65% compression and 35% the thicker ringlands that make vitara's hold up so well. 

Fixed, because the combustion chamber shape is a function of the compression.  THat, and because I am an e-bully and want to push you around.

FUCK YTOU! I cuss in front of his wife.


But never in front of sweet drity Cambodian women.  Mmmmm... Jay's sisters in law do something for me.

Not true.

It does when you are trying to get any bubbles/blows out of the casting. ;D

ok.  sorry mr. Davis.  I take that back now.  Are we still niggaz?

[turbob16hatch]

Shit i'm running vitaras and ls rods in a d16a6 7.1:1 with a delta 272, fuck low end power.

[ApexSilver06MR]

how much boost are you running there sir?

Joey.  What is this I hear about you, Goforth and Dirty Cambodians?
