Because of this particular post from Chris Lyons, I may have to re-evaluate the dyno situation at higher hp levels.
6. Pistons: I like J&E and CP's there are others. I had a really bad experience with Diamond. This is one place you want to find a machinist who knows how to spec a severe duty piston for a turbo application. Remember you are building a piston for a 1000hp motor that has 2 less cylinders so that piston will see more severe pressures and heat than a V8 piston would. Use the biggest baddest pins you can find and don't worry about reciprocating weight. I believe I had 220 wall 927 pins and have ruined most all others smaller than that.
I am using STOCK JE pistons pins... How much HP are they good for 600, or 800HP? 1000HP?
Maybe I should limit the hp goals..
Here are the specs:
Coating: None
Edge Type: Sharp
Length: 2.750in
Nominal Weight: 137g
Outside Diameter: .940in
Outside Diameter Alt: 23.8760mm
Series: 51 Series
Type of Material: 5115 Low Carbon/Case-Hardened Steel
Wall Thickness: 0.160in
Wall Type: Straight
Not sure what this comment meant?
8. Heads: I like stock style and see no reason to run S2's. The S2 heads were not designed for what we are doing with these motors
