This causes boost surge, especially at higher RPMs. This plays havoc with the computer, because when the belt slips boost drops and the computer tries to lean out the mixture, then when the belt re-grips, boost spikes faster than the computer can compensate. This makes a lean condition underboost which is a killer of exhaust valves. Especially when the Mini Cooper guys run the smaller pulleys to a boost. I've had to replace about 10 cylinder heads in two years on modified Mini Coopers. Now running this supercharger on a larger engine it will not create as much boost so this condition may not apply but I even have slippage problems on my other TI that runs the 15 pound pulley on a Downing Atlanta kit. Mine only fluctuates a few pounds when it does it. But with minis having a smaller pulley to start with when they slip they seem to drop about 1/2 if the boost. Hope this helps under stand my point of veiw on this setup. I also wonder what is the max boost that can be achieved by this kit and weather it can maintain that boost throughout the RPMs |
Hmm so should I hold off? Because I'm not looking for crazy power. Just 200 to the wheel and I'll be more than happy
