Hasnt been decided yet. It would be nice to have PPRE tune it when they are in the states for next Formula Drift season. Or possibly Nelson Siverio here. Need someone who understands how to tune in 4D with alpha-n and boost compensation, so that we can use TPS for load sensing in cruising, and refer to the MAP sensor for load sensing under boost only. That way the pport can be tuned more precisely, as standard map based tuning will have very low vaccuum signal.
Either way, sounds awesome.

To increase system cooling, you would aim to increase system flow, or at least reduce decreasing the flow. Plumbing in parallel would also be tricky, since one heat exchanger would be smaller than the other... Trying to match heat rejection across the two would be an effort. Ideally, you would have 2 equal cores, or just one larger one.
It is a common misconception that you need to slow coolant down in order to increase cooling, and "give the coolant time to absorb the heat energy". Cooling capacity increases as flow increases on a closed system.
But... Cross thag bridge when it comes to it.

I would rethink this option (if it comes down to being required). Plumbing in series increases pressure drop across the heat exchangers, which reduces total system flow. So while you would have more heat exchanger, you would also have less flow, which could prove to be an issue with rotor cooling as the coolig moves towards the rear rotors. Decrease flow enough, and the coolant could very well be boiling by the time it reaches the rear plate.

Thank you for your input and concern. Very good pts. The engine is utilizing an ewp150 electric pump. If flow is decreased enough to offset the additional cooler, a secondary inline pump may be considered between the two cores or on the return. There are small inline pumps from companies such a mezziere that move quite a bit at low amps as auxillary pumps
Theres also a good bit of room forward into bumper where a new radiator all together could be fitted. Core support could be removed etc replaced lots of options just want to get running.
Anyhow thanks

Who knows who cares
Maybe it is maybe it isnt lets fire up the storage unit built 26b racecar and see
at this pt, brapping is goal #1. If it gets hot we can build a radiator the size of texas and a water pump from a nuclear submarine.
Considering the ewp max inlet and outlets are 16an, and PPRE suggested 16an, id say its sufficent

awesome job
keep it up and long live the rotary engine. i have been planing on starting the 4 rotor conversion so hopefully someday i will get it going. Certainly your progress is getting me excited to start mine.

love that hat lol 
" at this pt, brapping is goal #1."
I couldn't agree with you more. Run the car first then work out small kinks.
I'm guilty of it myself. I overengineer and overthink everything. It's hard to move forward at times. I've had my engine sitting in my living room. I mounted a/c compressor to cool fuel before going into the rail. AC compressor will be engaged only when TCS is on OR when accelerator pedal is not applied. After playing with it for weeks, I just need to get it back on the car to run it then work out the details later lol.

I don't see the line size being an issue.

Thank you guys for the consistent following and commentary.
Many times, the internet is disappointing in that text-language can take on so many different inflections/tones in one verbage and I can only hope that you guys can feel that its all excitement here!
I appreciate everyone's words and suggestions/feedback. This has been alot of hours and work and at this point it scares me to even consider driving this thing! But, I tell ya what, its become a roller-coaster of emotions that ultimately always end up with love for the rotary.
Glad that there's people to relate the obsession with; the normal world thinks of us rotards as a bunch of hermits; we can't exactly explain why we obsess over the triangle machinery, why we put ourselves through the ambiguous world of witchcraft engines, but we know in the end its rewarding to hear them run!

hey thats a great idea for N/A!
Thanks for offer
Yea been reading up on this. A great guy Zebbi from NZ in here was telling me about how he tunes GTR's with ITB's on TPS as reference for all RPM points in vaccuum for fueling, using MAP sensor only for boost compensation and MAP sensor for Timing. Same should be applied for a low vaccuum engine, super large throttle body, etc

but i guess a GTR with ITBs has the same problems a turbo PP does.
luck with your stuff, i work at a dynoshop and do tuning, have you decided on ecu yet?

Haltech 2500 installed and harness / ignition etc all finished and ready to go
Where are you located?

Here are a couple of pics of most of the kit together
Here I included some of the pics of the kit so far hopefully it should be completed soon. Seriously thinking of start to order the 4 rotor kit and get my people working on it. Working with some of my contacts to start offering rotor lighting, and all cnc machine things that can be done to rotors and also perhaps start working on billet side plates including 20b center plate.
