Those look really good. I have been waiting for something like this.


what is the length of runners 1 and 4? they are shorter.
I was just thinking about the un-equal length stacks just the other night and trying it out on a honda application. You would get good response and a slightly improved midrange with the two longer stacks for every other cycle in the firing of the engine. They have been doing that with V8's and other race motors forever.


What applications will be made other than B vtec??? I would love to see those on an H22 also.
