[Straight 8 Racing]

From the non Technical Department,

We had detonation issues on our engine at the top end of the rev range on the dyno, we changed to very high octane fuel (109) which appeared to solve the problem, however it transpires that we were only masking a problem with the water pump and its ability to disperse the heat at the top end of the performance range. This issue has now been solved with the addition of a "De-Aeration tank" that helps to strip out air from the system caused during high rpm, if you are interested I will dig out the single line diogram and post it along with some pictures of the installation,

Regards
