Can I ask what sort of intake you have fitted as well or is it a panel filter type?

With regards to the gearbox that is a good idea actually, although I can't say I have ever felt it was over-geared - I guess it must be.
I thought it had an LSD..unless it was the GTNs?

The air filter mod replaces the entire plastic air box with a large ITG cone/barrel filter where the air box was. Whilst you have this off I would also recommend bracing/replacing the long length or rubber intake tube with aluminium as at high load the intake vacuum can collapse this.

You can easily see how the high torque to weight of the Aero is hindered by the manual gearbox (auto’s being programmed to overcome the mechanical shortcomings) by the superlative ease with with you can melt the rear tyres in both first and second - also by the rpm drop between gears. A closer stacked ratio set starting near where second is would help with traction to some extent and also drivability further up.

As for the type of lsd - the quaife unit has more reliable characteristics - especially when hot.


Thanks cerealsurfer, I presume nobody sells a kit for the Aero so its a homemade job?

What are Aero's like for heatsoak? I have seen a lot of performance tuning companies themselves turning away from cone filters and going to modified boxes with a cone filter inside (or a panel filter) for this very reason. Albeit usually on more convential cars.

Interesting on the diff, I have never tried to launch in second gear, might be worth a try..

Re. intake mod - for most cars the the cone filter is in the engine bay so it’s not so handy. Though tbh - the Aero are intake is very convoluted and not ideal. The intake below the radiator is ducted over the N.S wheel arch terminating in a aluminium housing effectively formed by the inner wing just ahead of the bulkhead and the chassis. Within this a large plastic box sits which houses a panel filter. This box is connected to an approximately 3 in or so pipe which turns 90 Deg and then extends back to the upper front of the engine bay where upon it does a U turn and enters the inlet manifold air box. On the race cars this near 6ft of hose was removed and air ducted directly from the upper currently blanked off faux grill. Reducing 6ft to about 6in. Over the full length of the basic install there is plenty of heat soak - especially as the NS bank exhaust and cat is not that far away.
