Very cool setup! Have you experienced Higher water temps at idle? I would apply this to my dd so sitting at stoplights is a concern. I'm just wondering about heat soak for the radiator possibly because it's so close to the runners/collector? Can't really see how close they are from the pics.
I'd love to see some dyno numbers with built heads, a large 30r, and meth!
Thanks and good luck with progress. Hopefully this will go into production.
