Anyone know if it's difficult to get an SR8 onto Trackdays requiring sub 100db?
I assume it would be tested as a car engine and not a bike engine?

Castle Combe measure car engines at 4500 (I think) and bike engines at 75% of max rpm. Goodwood everything at 75% but their meter reads 2db higher than CC .

I hadn't considered a knighthood was required at Goodwood, but it's probably a good idea. I always thought i'd be more welcome if i had turned up with a moustache and a real C Type. I think the staff there have begun to believe their own proposition, ie regard yourself as privileged to be here. However, that's another story, and in any event they run 105db days as well as 98db days so drive by permitting, (the one just after Fordwater seems particularly sensitive) I hope it would be possible to get an SR8 on, sub 105 at 7000 rpm. This would work at the MSV circuits too, just leaving CC to try and get to sub 100 db at 4500. I guess they could be convinced there were no motorbikes with 2700cc V8 engines. The question I am asking then is, is it possible to get an SR8 to 100 at 4500 and 105 at 7000?
The Radical TD silencer bought for my SR3 was not good enough, and I eventually had a system made by Neil Handley after some attempts of my own (sorry to hear he's gone bust and sorry to hear about your loss Sigmamark7)that got it down to 98, so is it reasonable to assume the Radical TD silencers (I think it uses two) will not work either?
