Alan, Where did you get your gears TVE treated ? And how much was it ? Thank you

[alanoo]

It was with a batch of prototype parts from a friends work; can't help much on much on that... It's not an expensive process... but I'm not sure it can be done on a single part basis

You will max the supercharger put way before you need these

no the real restricion is the inlet manifold you can always gear the SC down to stop it going above max rpm. Where as the gas velocity will choke the inlet manifold at just over 7krpm no matter what you do else where.

Exige S is capable of 330bhp with the eaton MP62, and thats only 1.8 but then does rev to a redline of 8.5k rpm. There should be more to had from the supercharger - could be worth looking into a better inlet manifold, and then maybe look at destroking to 2.0 and running higher rpm.

its a shame the gearbox implodes above 250bhp

There's a cheap solution to that now.

Close ratio Honda Type R gearbox conversion

But as he is going low compression you need a 2.9 pulley to get the magical 300 which pretty much puts the sc on it's rev limit as I have been told by the trusty Americans! Hopefully at the starting point to get a new designed manifold made that will make the charger sit slot lower, it's exmantaas idea also to have a better charge cooler and also a much easier and direct route for the ports

Any difference in parts/material between the Z22SE and f.i. the Saab B207 or Z22YH pump gears??

the z22se oil pump is best regarded as the 'early spec' pump, the saab B207 and z22yh both use the same revised 'later spec' oil pump.

the GM Racing oil pump gears are billet, the standard are quite poor quality in comparison

Would the z22yh/b207 part be a straight swap for the z22se?

straight swap

if you try and buy a new oil pump for the z22se (from the dealers) they will supply the 'later spec' z22yh oil pump

Hmm very good value

Although a 5.0:1 final drive is

I immediately thought about you when I read the specs for it, before Christmas.

No current plans to venture near the office. Do you need something picking up? If it's not urgent, I may go up there the week after next.
