I'm sure some of you would be interested in the in-car video from my EG/K20A from the Super Street/Eurotuner Time Attack at Buttonwillow in mid Nov.

This was using the Honda Challenge setup but about 200 lbs lighter, open exhaust and hoosiers. I had minor problems with handling (wandering on the straights), brakes (worn out) and the engine dropping out of VTEC, but the car still was hauling ass.

The low final (5.062) makes the car sound faster than it is but this video gives an idea of the straight line speed - passing the Celica 'Extreme' supercharged 300 hp 2ZZ.

Oh - next year I'l be racing SCCA Honda Cup. I can build the engine - rods, pistons, compression, head, so are going to make a little more power ...

Standard Sony mini DVD with wide angle lens. The sound pickup cannot handle the exhaust noise level, but otherwise works well.

Low final drive makes the car seem faster than what it was. Last time the magazine had a radar gun on the straight, but I didn't see one when I was out there.

Afterware I found that the front brake hats had distorted, and I had wierd wear patterns on the wheel / hat interface. That could explain why the car would not go in a straight line. I've re-machined the hats and have some more hats being made of a different design which should help.

Since Time Attack I have isolate the VTEC oil from the cam journal oil so that VTEC has more oil pressure and also the cams get proper lubrication out of VTEC. I have put in a quicker ratio steering with electro-hydraulic power assistance (a convential rack with an electric pump to provide hydraulic pressure), which I'm still finishing off. On the engine dyno a standard DC5 p/s pump took 8.5 hp to drive at high rpm. Electric motor should be less than 1 hp.

First race is at California Speedway on Feb 5/6 - with the 'low drag' civic with no rear wing and special front spoiler to see how fast I can go on the oval.

The year the engine is still much same as last year - standard compression, head etc so I'll make more power once I get a chance to build the engine.
