maybe 210-220hp as an absolute max, you don't see standard cams running faster than 105mph trap generally regardless of boost or other tuning! I think ant@ backyard maxed one right out at 108mph, or there about. I told him he would never go quicker than 105mph with his standard cam, he had to prove me wrong :D Ofcourse he went much quicker when he switched the gas on.

Moving on, the piper 285 usually tops out at 112mph then, regardless of boost or other tuning. Timing can have a big effect on the 285. I don't know how much extra you could pull out of the standard cam with timing adjustments, not much I expect.

I went 108mph on a std cam and turbo.

My aim is 110+ on road tyres too.

108mph is good for a mid 12 with a good launch !
