Hi guys I'm trying to get some idea of ratios but I can't find a website that show RPM as well as MPH I did find one the other week but seems to have vanished when I found out my 930 box was a paperweight.
So far I've come up with this
Tyre 26
Rpm 8k
1st 2.91
2nd 1.93
3rd 1.26
4th .96
FD 4.13
1st 51mph
2nd 82mph
3rd 119 mph
4th 156 mph
Cheers andy

Oh and just to confuse the calcs, a 26inch tyre grows by 1 1/2 inches at 150mph in tests by Mickey thompson

Especially as that tyre calculates to 24.68 inches tall, put a 26inch tyre on there and that is stupid tall for a drag car  |

Can you not get new ratios for the 930 box, or are the prices ridiculous?

Sounds like a simple case of needing more Horse Power
Wish you were on this side of the pond and I'd be glad to take it off your hands
