hi you all
just one thing getting back to the wheel sizes i have been racing in speedway
and have measered the differance between sizes13,16 with the 16 on i would get more top speed by about 10kmh and lose a bit of lower speed all what we come up with is the rpm would rev out more by 600-1000rpm with the 16 on the oval track is about 450meters we were going around in 21second.
my little race car was a datsun 120y coupe with a14 twin 40mmwebbers import gsx rally head 30/70 cam flatout second gear would get 110-115km really floging it.
