We have made 20 passes on our LSX block with the 106mm turbo pushing 2000hp. We have since then upgraded to the 114mm turbo in hopes of making over 2500hp but found out at the same boost levels we ran with the 106 to the 114 we ran out of fuel system and hurt a head gasket. We decided to pull the motor and check everything over after these 30 passes to see how this new LSX block was holding up. Well here are some pics of the bearings and block. Even making over 2000hp for right at 30 passes the bearings and block still look new. Just thought some of you would like to see this info.

GM Iron + Crazy Boost = Insane HP AND reliability. Thank you for showing everyone this is possible.

Cool Have you noticed any cooling issues witht he paint flaking off in the water jackets? Or is it even an issue in your guys car?

Steven,
Can you post a picture of the block in the main saddle are of #3 and 4 main? Is the crank turning color on the thrust surface thats burnt on the mains?

i think that color change is really not a color change at all...its just the material the bearings are made of that look like copper color.

No the crank didnt show any wear. The back of the thrust bearing did due to the converter balooning a touch. I will give it a little more clearance this next go around. But for making the power that we are making this thing looks great. LME is bumping the hone through it and we are slapping this thing back together with some fuel system upgrades and we are getting back at it. We are going to do some racing on radials in the near future

Those are o-rings for the copper (just an assumption, that's what the SSO car I worked on used. They might use cometic gaskets or something I don't even know about, hah) head gaskets they use for that engine.

That looks like it's in real nice shape, glad to see that these engines can hold up so well under severe duty.

awesome!

what oil have you been using & what viscosity??

I am getting the same thrust look and the polish on 4 also, not just on the LSX block. I would be interested in pictures of the surface the #3 and #4 main cap sit on as well as the mating surface of the cap if you can get them. If your thrust surface was to tight it would most likely burn both sides, I think its the building of boost that causes it. I am seeing it on engines with 500 less HP, but more runs.

I know im not the most advanced engine guy here but I would eb more inclined to think is from the natural tendancies of driveline resistance to force the crank forward after appliing that much power to the ground I know inertia forces thing rearward in the car but naturally with a link such as a torque converter the "joint" will spread therefore forcing the crank forward in the bearings wearing one side "rear" of the thrust bearing. too complicated??? i think i got it explained how i wanted *shrugs*

Those rings in the block are receiver grooves. More than likely they are running copper head gaskets with that setup, but who knows. The Ohio boys swear by GM GMLS stuff.
