Just my 2 cents worth
Personally I had the rev limiter at 7000rpm so I could have a bit more top speed not to make more power. If you look at the g-tech graphs, on my setup max hp is made ~5300-5400rpm so no more power is made above that. Actually when I look at the logs, my fastest 1/4mile times are made when shifting long before the stock rev limiter (shifting ~6000 - 6100rpm).

You are right, one of the suspected reason is detonation. If it was detonation there should be signs on the pistons and I'll check them when I have time to take apart the whole engine. Good point on oil surge, that slipped my mind....but if oil surge is the problem, wouldn't we be seeing the same issue with the other boosted engines ? As to the harmonic damper, this time I'm going to keep it on the engine. If it's not a problem, can you post a picture of you trigger wheel setup, in my opinion quite a few people will be interested in it. Thanks.
