That's an interesting manifold, I've never seen one done like that before. I don't remember, does the RX-8 exhaust come out of the irons too instead of the housings? Is that why there are 3 ports on there?

Yeah I'm curious too haha. Unfortunately I won't be able to provide any dyno results since I don't dare get on another one HAHA. All I'll be able to do is give a report on what the butt dyno tells me, how fast it spools and all that. Also, I'll be at a disadvantage due to the 6000' altitude as well, but I do plan on taking this to DGRR this year (assuming I can get it all done in time), so that should give me a better idea of what it will do near sea level. Otherwise I guess I'll run the current turbo out there. Either way, I'm sure I'll be reporting whether I'm happy or not haha. MAYBE I'll get on the dyno just to do a couple pulls, but no tuning, that's when tragedy strikes. I've been fairly lucky enough with just dyno pulls though.

Hey Eric.... basically as far as the exhaust goes, the theory states as for turbo engines that the longer the runners, the more top end power you'll get for a variety of reasons. However, you're after response anyway.

As Peter pointed out, take a look at the Twins Turbo manifold. Beautifully constructed, out side the box thinking, not all that impressive numbers.

As for your tuning experiences.... get a better dyno guy!

What's breaking and what boost, timing, AFR's etc etc etc...
