The Racetractor. The End.

[Piggy]

so got some shiny stuff, which you will know if following on instagram.

Stripped the spare GTB down this evening. Need some new vane housing bolts which are made of nothing by cheese annoying and didnt come in the rebuild kit from Turbo Rebuild company up north.

Anyway, heres the old comp wheel next to the new one

Note, the extended tips down the shaft and width at the base slightly. Its lighter, only by about 3-4grams, but every gram counts towards that 1 tonne target

After a lot of calculations with a LOT of Ruans help, and lots of googling (how ruan fits all that info in his head is mind boggling) I came to the 6+6 blade rather than 11blade. This is going to be the limit really of the GTB20. But I would love to see if she will blow 250. But a more reliable 225bhp will be pleasant. 

I'm not replacing the bearings as they are good and original, only done 40k, which no doubt the kit wont have as good bearings. But the oil seals on these are a weak point imho, so they will be replaced. 

In other news, the repalcement windows have arrived, I got a puncture (0psi) but didnt realise till I drove it as you cant tell due to no weight in rear

but she drives real nice. Fresh brakes, a bias, wider tyres, thicker rear ARB and low weight really make for a lot of fun. 

Arduino also close to being redone. Managed to get it running off the car 12v now without interference. 

Next: custom manifold, new exhaust, new FG bonnet too. Lets hope I can get it all done for FCS 

still need 16" rims for my track tyres
