I have an Aerorace, but with 210Hp Zetec (head porting, Jenvey ITB, Catcams camshaft, KMS Ecu management, 4-1 exhaust, raceline oil sump) for now set at 7200 max rpm . Previous owner claimed 235hp on the second engine but it was with more bore cylinders and special burton power larger pistons, rods , more extreme camshafts.
This engine is waiting to rebuild, so I can not confirm this power.
But - 0-100 time in my case is closer to 6sec. Looking at graph from racechrono it is obvious that main problem is time consuming gear change. It might be the case of my gearbox - MT75. In original Aerorace it is Type 9 gearbox as I saw on manual for this model.
As for the brakes - no need for haevier vented discs. I ve made so far approx only 300km of track use. But no issues with overheated brakes. Mainly because of lightweight, propably also because of much braking force on the rear so not only front brakes ale working hard.
yes, a lot of fun
