As Green mentioned, I have been playing with an intake or two. As he also mentioned, mine isn't as glamourous looking as Hogan's, but getting better with each effort.
If I was to do it again, I WOULDN'T. Way to much stress, work involved.
But with that said, I did, and will be pulling my own ty apart in a week or two, to install heads, and hopefully my custom intake.
I like the ramjet idea, for fact 90% of work is already done. That mod could be done in quantity if it proves to work well.
