i calculated the gear ratios for a target of 65mph at 24000 rpm. i have run the 4 stroke a bit higher than that at 26500rpm. i also based it all around one engine when i started the build, so i more than likely will have to re-gear it for more top speed, however whats in here will be a great test for the car.

ITS ALIVE!!!!!!!!

well, it was for 20' anyways. got it running today, both engines fired real nice. i guess i forgot to loctite the screws on the left side engine mount, they fell out right away and stripped the spur gear. i did get a video, not much to see but at least it gives an idea what this beast sounds like

got some more time in with it today.

still have some kinks to work out. i noticed one carb was binding up due to the angle of the linkage so i was limited to around half throttle. the transmission also wouldnt shift, might be due to lacking full throttle, may just need some adjusting.
