We'll check the motor, but all of that is somewhat besides the point. First, with the plumbing and inter-cooler, nothing much larger than dust could probably get through. But more importantly, we're probably done with this motor. We're planning to drop engine classes again, down to 500cc. Who knows, maybe we can get 200+ horsepower out of a half liter. Does anyone reading this have a racing 500cc motor available? We've got some leads already, but it doesn't hurt to ask. Just for comparison, 500cc is just slightly larger than a 16oz Mountain Dew.
The turbo we were using was sized for our 1500cc motor from a few years ago. It lagged a lot with the little 750cc, and that was something we'd been struggling with from the beginning. We pretty much knew we'd have to get a smaller one with a 500cc motor anyway. It would have been nice if we could have gotten one more run out of it, but the old one was probably at its last meet anyway.
