I am interested to know if anyone has tried Hilborn style injection or direct port injection, such as right into the rotor housing. Anyone tried a third spark plug. Dry sump. Anyone made there own ignitions, intakes or exhausts. Anything that could fit in this topic.

Hey what can I say, I got a small machine shop and I like to play. Got to see if I can build a handgrinade. There are not many sites that talk about hardcore racing modification how toos, I think they are afraid to give any great secrets away or losing money. This is a site that deals with aircraft rotary stuff, but there is some interesting stuff that could be used on cars. http://home.earthlink.net/~rotaryeng/ACRE.html and some other usful stuff http://www.diy-efi.org/diy_efi/ http://www.dynopower.freeserve.co.uk/nitrous_oxide/

I realize most of the people on this site probable drag race their street car, I just care to build something I can take to the track buzz the **** out of it and have a little fun! So I am game to try all kinds of things.

DO IT! we need more hardcore freaks with the need for speed and power.. the guys in australia and japan tweak the **** out of their engines.. here we're all worried about reliability and $$ if you have the $$ and resources we would love to see what you can do.. sorry i can't help you much more than giving you my full support.. i don't have much knowledge about wtf you're talking about but keep us updated

Well now that is a very cool idea. And of course it would work, because the mixture wouldn't combust as completely with the trailing ignition off, thereby lowering the temperatures.

that is a very interesting site......i like the ideas.....especially the relay on the trailing plugs....
