Upgraded the Gearbox Options!!

Wed 14th November 2007

I spoke to Chris frm Raceline about a new engine, lightened flywheel and bellhousing again today. He then offered to do a deal on an upgraded type 9 gearbox. A friend of his has a 2.8 type 9 box with a long first but with the heavy duty bearings and modified oil channels. The alternative box is a reconditioned unit with good ratios for road use. The 1st gear is a standard unshaved helical cut gear (not OE) - these gears are slightly noisier than original equipment gears. Because of this I can have the heavy duty box with a long first gear for same price of a normal duty recon unit with a long first.

After a bit of thought I decided to go for it. The issue of a slightly noiser first gear won't matter much in a kitcar. Kit cars are noisy anyway as they are all open and there is no sound deadening to cover up road noise etc. It would be pointless really, so the slightly noisier first gear won't change anything. Besides, the heavy duty setup will be better for me as I will start off at around 175bhp then I uprate the engine and management to around 205bhp at a later date.
