Have now completed three sets of 10 powerseat runs where I snap on the throttle in 6th gear at 3000rpm and hold it until 6000rpm. Really enjoyed driving the car so far, however I'm still getting used to the clutch when pulling off from standstill.
Found a few things that I need to look at:
When the engine is hot, the starter struggles to turn over the engine. When I let it cool it cranks fine. The issue is due to the high compression pistons now sealing a lot better. Have done some research and it seems to be a common problem. Fixes are either a different set of starter gears with different ratios, billet strengthened starter casings / gears and finally a choice of a more powerful starter motor or a 24v starter system.
The brakes are getting a lot better and are quite progressive, need to check the balance adjuster settings.
I still think that there is an issue with the charging system. I found that when I went out the battery voltage was at 14.9v and when I came home later it was down to 12.5v, however did start the car a couple of times while the engine was warm. May be that the starter motor using a lot of current and draining the battery.
The electrical system may also be loaded quite heavily, I have two fuel pumps, ecu, dash, can module, electric water pump, radiator fan etc etc. I will look at this and calculate if the standard 400watt stator is up to the job.
The induction noise from the foam filter is really fantastic and adds to the experience, only problem is it's too loud for track day use. Will look at getting a pipercross ducted airbox like the one fitted to Leon's car. This should quieten things down to a more acceptable level.
