Nothing wrong with your engine setup at all. If I could have found another one for a less than a crazy price, I'd still be running a Carbed oil cooled Suzuki because it ran like a beast. One major thing I always laugh at is hearing the newer motors banging off the rev limiter almost all the way around the track. I only hit mine once, on purpose, and ran just fine. I only turned my engine to 9200rpms because it didn't make any more useful power beyond that anyways so why spin it to hell and back if you don't have to. Another thing that I found helpful was my pavement experience for my driving style. Yeah, it looks wild to back it in, but I didn't have the horsepower to drive it in like that, I just drove it all the way through the corners so I didn't have to shake the tires loose.

As far as age. I feel old at 32 when I'm most the time I'm racing against drivers that aren't even old enough to drive on the road. For that, I'd like to refer to the viagra commercial where the guy gets the truck and horse trailer stuck in the mud. Instead of getting mad and banging gears, just gets the horses out and tows the whole rig out. Lets call it the age of experience to make things out of date by some folk's standard happen.
