Hey Doc, You can go 200+ on less than 200 HP with a lakster. We found a dyno we could use in Denver a couple of years ago. First time the car was ever on a dyno successfully. We were trying to sort our in our minds why the car was not going faster based on a couple of data points we thought were fairly accurate.
Determined we were not getting the HP we thought we were when we went 215. Tuning was the culprit... did I mention we are still working on that turbo tuning thing...
When Marty set the gas 90 inch record at 204 we had engine dyno data with the 65 ci zx11 that was 170 HP... we had to richen up a couple of jets to compensate for our inefficient NACA duct induction scoop
That is the same motor we added a .080 spacer to reduce the compression a little and 10 lbs of N20 a minute for me to set the 228 fuel record a couple of years later. When I kinked the Carillo a couple of runs later trying to back up the 230.5 we were running a little more juice than that.
The car body is 2 feet wide X 16 inches tall, the roll bar bumps up another foot and we keep making the engine cover bigger, it is at least 20 inches wide at the bumpouts for the motor. Since it is a lakester the wheels are outside all that. Yes it is small, but I am over 6' 2 and over 210 in my old age, and I fit.
So end of story, it is possible, but we don't have 15 feet of frontal or a .2 cd... don't think you can get that smooth with the wheels hanging out there spinning.
