Drag video

I was at the dragstrip and did two runs. First was 12.0 @ 117 mph, second was 11.8 @ 118 mph. With a little practice the car should be able to do an 11.5 or 11.6 @ 120 mph. Car weight was 2100 lbs, track was at 1300 feet, temperature about 70F. For comparison I did 14.27 @ 101.67 mph with the stock engine, but that was at 30 feet elevation.
R888 tires, coldish day, no burn out = wheelspin launching at 1800 rpm. I also had trouble with 5th gear - leather balls work better than alumimum I guess. The launch limiter sound is from the Civic next to me.

The highlight is the footrest returning to its normal position, and me wondering what the noise was.

There are several varieties of the K24, but the type found in the Acura TSX is the only worthwhile version. We bought one brand new (from a TSX in a train wreck), used it for R&D (which involved disassembling it twice without running it), then it went in the landspeed car (where it went 167 mph), then into my vehicle. Onto the K24 engine I bolted a Moss Motors supercharger kit, which uses a Eaton M62 supercharger with no intercooler. I was fairly careful about some of the minor details, like making a new thermostat bypass output and belt tensioner. This setup gave 151 hp more than the 2ZZ engine. A K20A would make a little less peak power but have probably much the same average power due to the increased rev range. An intercooler would make a huge difference to either setup.
The reason I used a K24 was because a) we had one sitting around and b) one engine mount is different from the K20 to K24 and the next engine I build will use a K24 block, with a shorter stroke so it will rev.
