Hi Scott ,

I use the same wiseco pistons , except mine are not oversize . i was thinking that route before i decided on the 300 . For interest , where does the ring locator sit on those pistons ? Over a port ?

Have tried the iridium spark plugs ?

Can you test on a dyno if ram air is adding to your hp ? or do you only feel it at 200km/h ?

Always keen to learn , Neal
