Your looking at the turbos up top. The Manifold is at the bottom

Oh ok, so there's an exhaust outlet that isn't shown in your photos. That makes a lot of sense now.
Pretty serious stuff! Incredibly complex. It's kinda funny. "Let's build an engine whose main characteristics are small size and simplicity, and add a heavy, large, elaborate turbocharging setup to it." Seems to work well anyhow, especially this BNR setup. |
It's overly engineered along with twice as many solenoids, vacuum lines, etc.

I suspect the long-term answer is going to be a motor/generator attached to the CHRA like they're doing in F1 right now (MGU-H). Use battery power to spin the turbo up, then take power off the turbine shaft to recharge the battery once it's making boost instead of using a wastegate. --Ian |
You suppose that will be implemented in the new RX-9 with there 400+hp goal?
|
Still need an intercooler, tune, and maybe a mid-pipe. I'm pumped with the numbers...
|
Why post a dyno video with no numbers?
|
Enter suspense:
311hp no torque numbers. Dyno was held for a meet and didn't have the equipment for a rotary. I am going to upgrade the fuel pump to a Supra tt running constant 12v to it. Then get a medium stock location intercooler. |
no torque numbers. dyno doesn't read that low of a tq figure
:giggle: jk jk 311hp or whp? if whp that's a good number for that car for sure |

What Irperformance indicated why my motor blew:
It was a complete rebuild with new housings and rotors from mazda individually. I have the receipt from the previous owner and the shop the built it in Sarasota. Irperformance discovered that the Endplay was too loose because the rear spacer was grinder/sanded down and reused. The Irons had too much heat and failed The catalytic converter melted The crank angle sensor was over sighted and the bracket was broken so it wasn't reading the trigger wheel accurately. Ultimately the apex seal chipped from detonation. If Irperformance wants to comment, please feel free to clarify even further. pictures: https://flic.kr/p/Tf6Bxwhttps://flic.kr/p/Tf6Bxw by https://www.flickr.com/photos/geraldmugar/, on Flickr https://flic.kr/p/TQaaBrhttps://flic.kr/p/TQaaBr by https://www.flickr.com/photos/geraldmugar/, on Flickr https://flic.kr/p/SAmKaXhttps://flic.kr/p/SAmKaX by https://www.flickr.com/photos/geraldmugar/, on Flickr https://flic.kr/p/TQaaJkhttps://flic.kr/p/TQaaJk by https://www.flickr.com/photos/geraldmugar/, on Flickr https://flic.kr/p/TCH1RKhttps://flic.kr/p/TCH1RK by https://www.flickr.com/photos/geraldmugar/, on Flickr https://flic.kr/p/TLxb7Ahttps://flic.kr/p/TLxb7A by https://www.flickr.com/photos/geraldmugar/, on Flickr |
And someone cut my oil pan baffle. I have no clue why they would do this

The Oil Mixing Pump was heavily scored. Its being replaced with a new one.
https://flic.kr/p/TCH2X2https://flic.kr/p/TCH2X2 by https://www.flickr.com/photos/geraldmugar/, on Flickr The BNRs have minor chipping on the front turbine. They were built to withstand a apex seal shooting through them.

Wow, that's some serious carnage.
Good ness I love your car. |
Damage notwithstanding, that engine is remarkably clean for a rotary. IDK about RX-7 circles, but I do know in RX-8 circles, it is recommended to inspect the cat frequently for any signs of clogging. It is also recommended to replace the ignition coils, wires, and plugs every 20K miles--more often if you frequently take advantage of the high redline. Generally speaking, a weak ignition system results in a clogged cat, which then kills the seals.
I LOVE your car, but reading this thread reminded me of why I can only own one rotary at a time. |
Oh my god your car is gorgeous.

Had a blast with the car at Deals Gap Rotary Rally. We had to replace the oil restrictors though because there is a lot of blow by in both the hot and cold side of the intercooler piping collecting around the silicone couplers. I'm monitoring the car to see if the new custom oil restrictor bolts that Irp made will help out. Fingers crossed.
