Thread: spun bearings

Tweet

Still say it detonated. No bearing or oil pressure will live with detonation. If it had adequate clearances and oil pressure, it wouldn't spin a bearing without detonation. There are cars running with twin turbo making 1000+ hp that are living fine without spinning bearings. Now if the engine isn't built right, that would be another story. I don't think that is the problem though beings the car runs 9's on 10lbs boost. If the waste gate stuck, there's no telling what the boost got to, but you could believe it needed more than 118 octane to run it. Do the piston tops or plugs show any signs of detonation? They may not show much since he let off so quick on the line but the whole engine would be toast if it had happened further down the track with the rpm up.

Sounds like it could be det......if it over boosted................
