We mat Brent L. through a BMW 2002. He raced one in SCCA ITB (Improved Touring B Class) and won all the time. After 13 years of running the same car, he decided to build a very competitive car for SCCA F production. We built the chassis last summer with big fender flares, wide tyres and a modern suspension set up. The car still had the old ITB motor in it and even with that power plant he was still able to tear one of the control arms out of the frame because the grip. We are not allowed to change control arms in this class but we can reinforce them, which we did. Now this season it's time for the motor. The rules in the new class gives us a lot more room to improve on the engine. We are limited by compression, bore and cam lift. We stayed well within all the rules but came up with some tricks. The pistons are 10.1 compressions ratio, they have groves cut into them to keep the air turning inside the combustions chamber. They are also coated in a heat and friction coating to make more power. The crankshaft was balanced and knifed edged for lighter weight and less drag in the oil pan. The intake valves are coated in Teflon to improve flow. The cylinder head is coated in a heat rejection coating to prevent head soak. Custom made camshaft will keep us within the rules but it's not "off the shelf" parts. We put it on the dyno before and made 112 horsepower and about the same in torque. We will see what the new engine will bring. Stayed tuned for updates.
Major update. We just raced the 2002 and it did great!! It was keeping up with 5.0 litre Mustangs and set a faster lap time then the Mustangs. WOW out of 2.0 litres. The power come on much stronger and pulls all the way to 7,500 RPM. We found the exhaust was too small and we are currently building a larger bore exhaust. As you can see from the pictures, we have two air filters and they create a ram effect into the carb. This is what we do, turn vintage cars into competitive race cars.
DYNO RUN!!!
