Plan was to be there. Think I've got the oil staying in the engine and not covering me now - issues with dry sump suction line fittings.
On the dyno today but it went bang while I was warming it up. Broken cambelt, no compression in two cylinders and about 10 mm valve clearances. Looks like valves/head/pistons are going to need some TLC.....
Found the pivot pin for the cambelt tensioner had come out of the aluminium housing then tried to go around the bottom pulley - hence the broken belt.

That's a bugger about the cambelt. Have you considered Honda power!

Good luck at the sprints.. I am working again, as usual.

Only 3 bent valves - sorted. No belt yet though.

Cheeky bastard.
OK, OK, I have a running 23 and goes pretty well. I haven't got the cage Homologated yet and I have a front hub problem which I'm reluctant to test at 200kmh. I'm having a break after 5 years on the 23 and plying with something else - but it isn't forgotten Neil.

Chuckle... at least your new car can get to 200! :-)

Maybe without the windscreen and if the front straight was 300 metres longer....

Yea, I recall around 190-ish, but staring at the speedo with the buffeting and a flat left hander at the end, well, it's hard to know for sure. And assuming the prick who set the speedo up did it correctly :?
I reckon the 23, having a cleaner shape and a bit more torque should push 200, however I'm still on road tyres, so would start the straight a bit slower. It's all theoretical currently thou isn't it....

Well I have a pretty sophisticated datalogging system in there now and it shows my max speed on the straight is about 180 before braking if the windscreen is off and there's no headwind. The speedo is spot on, at least with the current wheels and tyres!

It is slow on the straight though - even roadgoing BZR Truenos go past me near the end of the straight - of course long straights are boring and I kill them everywhere else. I still have no desire to add more power to it - it's astonishingly well balanced... Best money I ever spent on a car!
