  1. thanks for al the comments guys...much appreciate. Lots of mixed messages so still confused. Im not a mechanic so you'll have to bear with me but Charlie at Surrey RR said the measurement was taken at the crank, plus the RCF which performed the same test after me was pushing 460BHP so theres a huge difference even if the car is only a year old.
  2. they took it from the crank (which I believe is the same as the fly wheel), but as an RCF was tested also at the crank with 460 BHP i have to believe something is wrong
  3. Ive done 100k miles from new. All I know the test was done at the crank.....as a guide an RCF was also tested on the same day also at the crank and it produced 460 BHP, ok this was only 1 year old so i would expect it to be close to its original claim, but the point is its the same same test and huge difference. I actually used Surrey Rolling Roads in Farnborough (who was recommended to me by a Lexus mechanic). So have you guys had a BHP test?
  4. Hi ISF owners, I was wondering if anyone with a 7-9 year old ISF has recently had a rolling road BHP test? If yes what was your BHP? Was that taken from the crank/flywheel or the wheel/tire? Ive just had a new short block replaced along with a complete clean and rebuild (paid for by Lexus under my extended warranty 12k cost!!) after my engine was losing loads of oil but upon having a BHP test I am only getting 365 at the crank which is nearly 55 BHP down on what it should be. However Lexus are telling me that is about right for a 8 year old ISF so Im looking to see what others are getting from a 7-9 year old ISF (standard build - i.e. no enhancements)? Thanks Aaron
