I'm really not trying to talk you out of it or something, just showing you the consequences of the choice for the large engine. To me defending the "small and light" choice has become somewhat of familiar debate. I participated in a year of FSAE racing car devellopment. When the rest of the field was running 300+ kg cars, powered by 600cc 4 cyl engines (max displacement for the class) from R6's and fireblades, we started devellopment around the ultra light idea. The final iteration of the devellopment was a 120 kg car with a mere 40bhp from a single cyl engine. Despite its massive lack of horsepower it outaccelerated almost every car at the competition, reached more than 2G's at the skidpad and blitzed the roadcourse. Its just a complete different line of thought.
Another argument for the balance story: at the last autocross there was a guy with a clio that packed a Megane cup engine (220+hp), full suspension, nice tires etc etc. At the end of the day he was just two tenths of a second faster than my MX5 despite having double the amount of horsepower and the same weight. The guy also had a lot more racing experience then I had, he said he lapped the nordschleiffe in 8:30 tot 8:40 BTG Oh well, lets first see if the thing will fit in and take it from there. A wheel to steer the front of the car A pedal to steer the rear |
