13.1 @ 105 but only 14 psi!

reddevil · 09-16-2007, 04:16 AM

Was breaking the motor in untuned (runned rich across the map) and the new motor seems to be monster in the making.

13.6 @ 100 @ 11 psi
13.4 @ 102 @ 13 psi
13.1 @ 105 @ 14 psi.

Then I ate 1st gear. haha

The motor in question is
Phase 1 block 2.5 pinned cylinders
100 mm Mahle pistons
Stock STI crank and rods
820 cc injectors, modded STI sidefeeds
Twin turbo DOHC heads and intake manifold

Using a PerfectPower6 piggyback on the stock 1990 NA ECU.

isnt running rich to break a motor a bad thing to do?
any idea on CR?

Safe rich, not black smoke rich.

Compression should be 8.2-1 or somewhere close.
