Our dyno is particularly harsh, around 8-10% due to atmospheric conditions. Interestingly, a guy up here has SuperFlow engine dyno and he experiences the same. 8OOhp on his will show 900hp on the same dyno and software in Brisbane. Wheel spin at this level will account for about 30hp, this particular bike will go 330-350 on a dyno in Brisbane. Would make more hp with a bigger compessor but it's a street bike and it has enough, 8psi is good for 260hp. On my turbo funnybike I'm losining 100hp in tyre slippage, 30pi = 480hp, just have to sort some chassis kinks out. With the slick we only tie it down enough to hold it straight and allow the tyre to grow. With street tyres, we've found sticky tyres aren't any good as they ball up and cause more slippage. slightly harder tyres are a little better.
