Is there any truth in the new polini big evo engine hitting 100mph ? cratch: It does look pretty quick in the videos but theres not been any solid proof of it going 100mph. Would have to be pretty damn fast though;; it's on the market for around 3 grand ! :mod:
Probably dyno figures. There's a guide I wrote on speed vs wind resistance in the guides section. I wouldn't say it was impossible though. In a sprint frame with enough distance. It's a lot cheaper than 3 grand for a 94cc kit. It's about £700 for the kit crank and an exhaust.
