October 20, 2006: Sexy engine on the dyno.
We had an engine I've been lusting over on the dyno today at work. It's very similar to the one that's in the Seven now - except that it's 25% larger. 2020cc in size instead of my 1640cc, with the same sort of compression and head modifications. There are even a set of roller-barrel throttle bodies installed. I have high hopes for this powerplant. Given the better head that's on it, it should be good for 200 hp at the wheels.

Well, it goes very well up to 6000 rpm. At 4000, it has 150 lb-ft of torque compared to my 100 lb-ft. Boy, you'd sure feel that! Unfortunately, it falls off at 6000 and doesn't fulfill all the promise. If the power curve kept going and continued to mirror mine, it would be right around 195 or so. We think the cams aren't up to the job. We'll sort that out!
