I can’t speak for the bike engine cars in Europe, but I’ve seen the wrath of these machines first hand here in the ‘states. At a recent SCCA event, a friend of mine entered his BEC running against the big iron from Detroit. This included camaros/firebirds, corvettes, and even a 5.0 mustang full tube chassis, flared fenders with enough rubber under it to make the Goodyear rep dizzy, and over 500 hp on tap. The other contenders included an aluminum V-8 powered MG, Hondas/Acura of all flavors, Miatas, all wheel drive mistubishi’s, even a big valve caterham.
On the first round he had them beat by 10 seconds a lap, consequent rounds had them trumped by nearly 15 seconds a lap. This was without all the wheel spin, HUGE power slides, and mayhem of the big blocks. It was simply surgical, slicing and carving like a gold medal winning ski run.
Now if you want serious performance, turbo’s/superchargers can be applied, twin engines aren’t unusual, or the new trend is mini V-8 engines using the heads and cylinders from big bore bike engines on custom blocks. How’s this sound? 2.6 liter all aluminum V-8, quad-cams & 40 valves, fuel injected, dry sumped, 13,000 rpm redline, 350 horsepower, weighing 190 pounds (including a sequential 6-speed limited slip transaxle).
That’s in stock configuration, 2.8 liter and other options are available!
