Possibly correct, as I believe it has a higher percentage of bio. If that is the case is may be necessary to run slightly richer to get the best out of it.

As the former owner of a 182 Trophy I went through quite a lot of these considerations before defecting to a Honda Integra DC5, as for hill climbing I needed to be able to guarantee a significant increase in power. On the DC5 a decat is virtually essential to optimise a power increase. What is...

Ben R - delighted to see that you are doing this at last - hope it works out as well as it deserves to. regards George

Gear type diffs - as per Quaife can have different specs, depends mainly on the angle of helical on the small gears, which will affect the amount of locking.

The Xtrac transmission package is the FIA approved system for S2000 and includes a rear wheel disconnect as the types of centre diff are very restricted

Andy, I can't argue with your actual findings - do they suggest that the engine wants different cams/overlap - are you running the variable phasing on the inlet cam still?

Long tracts will certainlymake best torque, but at what rpm, this is normally at the expense of the top end - several years ago AMD tried an experiment on variable length inlet manifolds and found that the changeover from long to short was as low as 4,000? What do they do to the area under the...

Those inlets look very long - and will surely limit power at higher rpm (as in the case of the 182)- can understand the installation issues, perhaps the best compromise would be to go for tapered tracts, albeit even more costly.

Probably a question for Ben R - is this a case for vernier pulleys and different IP and EP?

You will find the optimum MX5 settings on Miata.net - they are known as Lany's settings and are a significant improvement on factory.

You will be stunned by this - Mk2 Cup cars: Front 18kg/mm = 1,000 lbs/in Rear 7kg/mm = 390 lbs/in Almost solid - hence need for specfic tyres with very stiff sidewalls.

Mike, what cams did you fit?

If you do not mind a much stiffer sidewall have a look at the Hankook RS2. It is a road tread and compound tyre with track type construction, a friend uses them for track days and sprints and finds them a good compromise. To get the best out of them run them at 28/26 psi

Details would be much appreciated - thanks
