I know about the fuel changes. And I didn't think I would be able to on that compression.
About spending the money, I will be as cost effective as I can. But in the end when you want to build your dream car for your fun, why wouldn't you if you are able to?
And as far as building against buying an already made race car takes all the fun out of it. By doing most of the build between my team and I, we'll learn so much about the car and its caveats and quirks that we can properly and more effectively eliminate problems that arise.
And since I have time to do it all, I'm in no particular rush to get there tomorrow.
