Awesome build and Engineering.
How will your tune account for the secondary intake ports? I assume that you will set your ECU up to trigger them, but is there something else that must be done? It will be seen by the MAP but not the TPS? RGHTBrainDesign Rotary Engine Development Projects This thread goes over it pretty well. Are you trying to apply this to your own work? I could guide you on that depending on your goals. The main downside of going DBW Single Blade TB is that you lose the functionality of the Primary/Secondary control via the Factory FC/FD throttle blade system. So my approach was to control the FD Upper Intake Manifold to do just that using the vacuum actuated flappers to control Primary/Secondary airflow. DBW doesn't really have a TPS, per say. It's Throttle Applied on the Pedal Assembly and Throttle Body Demanded Angle. That curve can be built out to do anything. I also don't have a single MAP sensor. I'm using what's called Throttle Mass Flow by grabbing data from two MAP sensors, one pre-TB, one post-TB to evaluate transient fueling airflow needs nearly instantaneously via Navier Stokes equation. My car is also comparing MAP vs. BAP (Barometric) and compensating for EMAP which directly effects o2 sensor control. Sounds complex, it's a lot of sensors, but the point is to give the computer as much data as possible and let it do the hard work. :) |
Nice. Man, I am jealous of the S2 instruments. The tach is in the proper position on those, the middle. And bigger.

Manifold Design is mocked up. Here's where she will sit. Finally seeing some progress here. Really happy with the results.
22" Total Runner Length from Exhaust Flange to T4 Gasket using the 2.157" ID Sch10 Pipe. https://cimg2.ibsrv.net/gimg/www.rx7...7068cb5c6d.jpg https://cimg2.ibsrv.net/gimg/www.rx7...87b5389076.jpg Ignore this angle. The turbo is mounted nearly parallel to the car's body. Might be able to add a bit more height to get that last bit of exhaust manifold runner length too. :) https://cimg8.ibsrv.net/gimg/www.rx7...4ed7b22647.jpg |
Hanging it from the angle iron across the fenders to position it seems like a good way to ensure hood clearance. Nice.

This week is going to be nuts. Stay tuned.

Very nice. Nice and unconvoluted. Im jealous of you LHD boys having all that room to do an equal length symetrical arrangement.
how did you come up with the headef length? |

how did you come up with the header length? Excuse the poorly written answer, I'm absolutely exhausted. New 7am-6pm job, spending time at fabrication for a couple hours a day, and prepping Full-Race and a few other companies for SEMA. Things are WILD right now. Yeah, LHD has a TON of room compared to the RHD guys. Your spark plug changes are nice though! :P |
Head pipe is sick. That giant turbo is definitely going to be a focal point of the engine bay with it sitting up so high.

Oops, I Forgot How to Upload High Quality on Rx7Club. FIXED! https://cimg0.ibsrv.net/gimg/www.rx7...8e2436fe89.jpg https://cimg4.ibsrv.net/gimg/www.rx7...9a15121eb5.jpg https://cimg5.ibsrv.net/gimg/www.rx7...a6d475ab39.jpg https://cimg7.ibsrv.net/gimg/www.rx7...4b5a29d2e8.jpg https://cimg9.ibsrv.net/gimg/www.rx7...6a8e59f2dc.jpg https://cimg0.ibsrv.net/gimg/www.rx7...05835fd757.jpg https://cimg6.ibsrv.net/gimg/www.rx7...0a167b37e1.jpg https://cimg3.ibsrv.net/gimg/www.rx7...cd6f25b4d1.jpg So, here we are... #FractalFB's Exhaust Manifold. Better start brewing up that Haterade... We're only going to make 500whp. |

Thanks for the support. :lol: :lol: :lol:
The proposed exhaust setup so far:
Should be absolutely bitchin' and relatively quiet, while NOT reducing a bunch of power. Laughing my ass off at these Dahm videos. I'll catch some of you at SEMA... #TeamNoSleep #NoSponsors #SixJobsIDontGetTired |
Amazing work! Keep on going!

So Let Me Put It This Way... https://cimg6.ibsrv.net/gimg/www.rx7...be8c98e1b5.jpg Don't. Get. In. My. Way. |
Really guys? Zero support? Zero input? I know the forums are dying, but damn, that's a shame.
The new proposed exhaust system is doing to be dual 3" oval muffler exits into a Y-Pipe single 4" oval that goes over (or under) the axle into the rear muffler which is around 5" x 10.25" x 18". Sikky Shifter came in. It's incredible. Worth every penny. Bellhousing is cleaned. Clutch Center Hub is getting dropped off tomorrow for Wire EDM to its new input shaft size.Ohh, and this gem: No sponsors, no drama, no bullshit. Just badass car design and fabrication. |
Great work as usual. Cant wait to see it running

Oh, I'm watching and reading, just don't really have anything to add over here. I'm just sitting here in awe of what this thing is going to be.
