1/4mile in 13.2sec @ 111 terminal on 15psi

yes looks good untill i saw the 5th gear ratio, i'll be sticking with my 4th for now, NO point in having a 1.1 5th gear for the road IMO!

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?

kads are 2.5 firsts IIRC

why not, well for a road car IMO it would be helpful to have a lower then 1.1 ratio for a 5th gear, other wise why don't i just fit a 2.7 diff to my 4 gears and save £1500, as i'll gain not revs and economy from it!

I like the look of the KAD box very much. Trapaezoid dogs have a longer life than involute dogs and engage better than "bean" dogs. It's a beautiful piece of engineering. The snag is close ratios. I accidentally bought a challenge gearkit and it has the problem inherant to powerful engines, whether they be FI or big capacity. You need a good spread of gears.

I'm sure that people will disagree, but overdriven 5th's are prone to huge bearing loads, especially if helical. I like the idea of a straight through 5th and a lower first, running a longer legged FD.

The KAD 2.4 first is lower than my ST 2.54 first which limits my final drive choice. Either that or it's a clutch plate a week. (when it's working! )

The KAD box is a beautiful design and if there were a set of spread ratios, it would make so much sense, I can't understand it, coming from people who build serious engines. You just don't need those ratios, unless you are doing rolling starts or racing short stroke screamers in the 60's.

Someone will do it at some point, as there is clearly a demand for a quick changing 5 speed box which allows a better spread of gears/speed.

It will happen in due course.

Bugger off, I'm getting there.

do you mean higher stu?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

I always get it the wrong way around. Longer legged!

Higher!
