ON topic - i cant believe there is no more wear in the bearing considering how hard you drive that car. its all in the tuning!

When I think dry, i am thinking solid block, with cooling channels, rather than an open deck, where coolant surrounds the cylinders.

Shariff.....how did the cylinder walls look??? Scuffing, any cross hatch left and did
you pull a top ring off a piston and see what the gap was compared to when it
was installed? Piston to wall clearances?? I know it is alot of questions, but
since your building one for me, I like to see what you ended up with after
your tough 25K.
How many dyno pulls was this engine subjected to over its lifetime?
And by the way, my car is running GREAT...THANKS!!!!!!

This engine has saw about 250 dyno pulls on the only dyno, and about 100 on the new dyno.
Glad your car is running well. We are getting caught up this week on our backlog of Forged engines, and I'll call you later, so we can get one staged and on the shelf for you. Sounds like you don't trust the "other guys" engine.

Sharif,
Can you post better pictures of the pistons.i am curious to see closups of the skirts, and the tops of the pistons near the ringlands. Also some closer and better shots of the bearings would help.The current pictures dont really show much.

the amazing thing is when you tear a motor down and inspect the valves and carbon deposit on the pistons when running water/methanol injection its entire life!!! Another reaon to add water to one's setup, the claim of "steamcleaning" you engine is true. The pistons will have some carbon deposits (as all will) but overall much less in a non-water setup...
for 25k miles those pistons look great, re-use em on your next build and put those Extreme duties to the test!

Oh and the bike was stolen to boot..
Sorry for the OT
