The big question : what have you used to seal the side exhaust ports ? Looks like JB weld or similar .....
Also , exhaust header has no turbo flange ?

77 cylinders, 4 rotors...
Can't wait to see Team's reaction to this when he emerges again. I miss/don't miss his input. You know what I mean?

I miss MazdaManiac's input too. I'm sure there are others as well. But at some point you become such a *****, people don't care if you give good advice.

I would love to see more about this. I like to see people actually build things.

my reaction is simply to wait and see; my position has always been that the cost and effort won’t justify the input of resources and hassle required for reasons illustrated and discussed in detail in various other threads on the subject
**until someone demonstrates otherwise**.

kilawatts, with all sincerity; I’m sad for you.

just listen to the difference here on the downshifts:
It’s easy to see why though. Once you change from a non-overlap intake-exhaust cycle scenario then all the rules change too. Nobody is picking up on one of the most basic ones that’s right in front of their face. No surprise at all, really.

Car is not full tune yet , just start up ready to brake in

To be fair in this current environment 1 month is not very long. Most good dyno’s around me which are many are all tied up for the next 2-3 months.
So no surprise. Looks a bit slow Erving compared to stock but not saying that can’t be cleaned up with tuning. Cool build for sure.
