Well, that explains why you can barely hear the induction noise and the supercharger wine.

It's not consistent. I'm sure it'll be more with a burble tune but don't want to damage the engine. Scared myself once with it pop since it was unexpected...

Mike,
How many Harrop kits have been sold in the US? Just wondering how special we are ;-)

2011 rod bearings?
So BMW changed the rod bearings sometime in 2011, but nobody can tell me if my car has the new or old bearings. I sent my last oil change to Blackstone, and there was 0 lead in the sample at just shy of 9,000 KM. There were traces of aluminium. Blackstone hypothesised that I am on the new bearings due to the lack of traces of lead. I just want to be sure so I can calculate the additional costs to get my bearings done prior to the supercharger.
When I contacted Harrop - they were on the fence and said that they can't be sure and it would be safer to do them to be safe before doing the supercharger? Has everyone with the Harrop setup done their bearings? What year is your car? Thanks! |

no, thats not just a smoothing issue, thats a knock issue.
smoothing 3,more boost less octane, nowhere near the same knock http://www.bigdynodatabase.com/DynoG...INTANI_COM.jpg |

How about moving this to one of the numerous bearing threads instead? Everything turns bearings and this is for the Harrop SC reviews/questions.

I suggest you look into the knock issue sooner than later. Investigate for yourself, see how many other dyno's have that rough of a curve. I would bet your about to be another victim of broken pistons/rod disguised as a "rod bearing" issue. I would stay away from any "shop" or "tuner" saying that is "normal" Dont say you havent been warned. |

Does Mike have a different tune for this or similar exhaust setups?

Yes. When you purchase the kit it asks you what type of set up you have so the correct tune ships with the kit.
