[quote=NickCW]Thanks cerealsurfer, that sort of output is about what I was looking for. Good to know of a tuner who has previous experience.
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.
Thanks for the info cerealsurfer, it definitely sounds like there is room for a lot of improvement so perhaps some trial and error on my part is required!
When you say the blanked off grille do you mean the upper section above the numberplate (the famous Morgan grille?).
I was thinking of adding the GTN vents to the front for aesthetic purposes, but if I can route one of those as an air intake that would be of great benefit it seems, of course if there is a way to stop/limit water ingress if it rains..
THe heat soak is horrible. Inlet air temperatures are in the 90C range after a run.
The GT Cup cars ran a cone filter in the front of the front wing, behind one of the "brake duct" holes, it worked well until it rained and the car stopped running. The Mass airflow sensor is rather averse to water.....
There's not enough space to mimic the GT3 cars setup on the production plenum and radiator
With regards to the V10, it doesn't fit without substantial body modifications
Find a crashed X5 4.6 and swap the engine for easy power. The Cup car in 24hr trim was 380 bhp with nothing more than a proper ecu and map, the VANOs locked in "power" mode and and a dry sump

Thanks Simon, again some very interesting stuff - I recall seeing the V10 when I purchased my Aero sat in the RT workshop. If I recall it was a standard 500bhp or thereabouts...

Nick -
If you look at Simon's (Simonrjw) Aero (that he bought from Viper),he has the air vent grilles in the front
'bumper',a la GTN.
I'm not sure if they are connected to any tubing - but I've always thought they looked good
I had planned to do something similar (and use the nacelles for DRL's) but I chickened out cutting the holes....
