G'day, Heres one for you engine guys. What do you all do about engine knock sensors. We are running the F4 CBR motor will custom made exhaust and intake headers and are running the autronic ECU. In the past few years we have lost a few engines on the dyno, as we spend many, many, many hours on the dyno, and are very comprehensive in what we test, but knock has always been a problem for us, especially with turbos.
Also for those of you that have played with internals sensibly, have you found any real gains in higher compresssion pistons and larger/smaller cams, adjustable cams. Have any of you found noticable gains with turbo-chargers and if so what sort are you using as the Garret turbos we use , we can't get any maps for and have found lots of problems with seals.
Oh yeah as well our car last year was getting about 80hp at the rear wheels with lots of usable torque, but our engine development stoppped at the dyno, as we could not do any real testing or data logging in the car.
Thanks for your help , see you on the track
