For ever.
Tonight I had a go in this :-
430kg all up weight and 8" wide slicks. That's 418bhp/tonne to save you the arithmetic. It's a hayabusa engine, quaife LSD, dry sump, lightweight chassis blah blah blah....
Anyway, the driver is very very very good indeed - he was in amongst single seater drivers last weekend and he offered me a go tonight on track as a thank you for sourcing him some bits for his build. I have never ever in my life been in something with such fierce acceleration and frankly unbelievable cornering power. Then there's the braking.
I thought I had been in quick cars - I hadn't a clue...
