Awesome - everything an FD should be, and no concerns about popping a seal under boost

I ammassivly impressed by the insectors spraying right into the velocity stacks. Also wondering what the three vertically mounted stacks are for.

Thanks! The three other stacks are ITB's that feed the small peripheral ports.

Wow, I just now noticed the massive amounts of grammitical errors in my pors, and I am also massivly impressed that someone was able to figure out what I ment. But yeah, I'm basically clueless when it comes to the porting aspect of rotary engines. When I'm finally able to build me a RE powered track car I'll have lots of research to do.

Awesome.

Hope you don't mind me stealing some ideas, and trying to copy this over to my 13b build (not that i think it will come close tho, since it's my first build...)
