digital camera battery died, but i got a couple shots...


12.5CR CP's .. on my street engine maximum we can get here is 91, the dyno will tell how much i can squeeze on it.. a full day on the dynojet will be needed to squeeze the hp

i'm charging up the batteries for the serious hardware

Holy chit, 12.5 CR on 91 pisstane gas? No need to retard timing? Good luck man, I'm hoping to run 12.5 when I start building up my K24 TSX and be able to use 93 octane daily. Also, did you have to resleeve the block to run the 12.5 CR pistons?

Nice to see you around...

So you still running the stock pistons, rods, and crank with these bad boys?

if he's not increasing the bore he should be okay.

Are these the shelf SC7147x? If so, once you get around to claying for piston-valve clearance - let us know how much you get with the Crower cams you're running at full 50 degrees VTC (if you decide to run a K20A(2) sprocket).

Our most aggressive cam requires a 0.065" deeper intake valve relief. The shelf part comes with 0.200" intake vr. Our customs have a 0.265".
