Ohh, what's up Mike!?! Woot woot, finally showing off an old build log from (originally 7Tune, then Adaptronic).

You've seen the progress on Facebook... Plenty of goodies in the near future. I'm going to finish the power steering and front coilovers tomorrow. ARP 12pts to the rescue!






Pew Pew! Problem solved!

I'm assuming you mean the Circuit Breaker which is from BlueSea. It's only rated for 100A, so relays are needed for all the Inrush power from each system. Not pictured is a bunch of 4/5 pin 40A relays and 4 pin 70A relays.

The fuse holder is mini-ANL with dual 4ga on one side and tri 0ga on the other... Not a fan of THAT design at all.

Great start! I look forward to following this thread with interest. Your mod list is basically a wish list of everything mechanical I am doing or planning to do for my Oz-delivered series 3. One thing I definitely hadn't thought of is using the choke **** for controlling a butterfly valve in the exhaust. Very very clever, well done. I am toying with the thought of an ECU-controlled valve (aftermarket valves controlled by actuator are available here), just like the bimodal systems found on Ferraris etc. Ie mapping butterfly valve angle against rpm/throttle position

Don't throw away that factory headunit either. They are still worth something to guys like me who want to retain original interior appearance.

When I pull it out and all of the original factory electronics, pay shipping and they're yours.

That's both Clarion amplifiers, 4" front Speakers, 6.5" rear Speakers, and head unit. It should all fit in a USPS Large box for flat rate shipping, but I'm not sure if that's Aussie pricing (if they go international).

The #1 problem with an electronic cutout is the motor/wastegate actuator can't handle the rotary heat, regardless of the design. I'm stumped and need to look into aerospace products to find a solution. Let me just say that the 304SS isn't the problem, it's whatever flapper AND motor is actuating the cutout, as well as a poor efficiency from using a y-pipe. Going to 321SS or Titanium wouldn't solve this issue...we'd want a motor mounted lower than the radiating heat and shielded by a ceramic sock.

Here's another thing to consider... Any Y-pipe in the system will lose power compared to a standard 3" exhaust system since air will go into that pipe and bounce back, creating unnecessary turbulence. On a 400whp setup, I'd expect it to lose me 20whp...but it would be awesome. With it open, the pressures are equalized, but NEITHER system is optimized. Here's a great video demonstrating this:



So if you're willing to make the sacrifice in power for fun, which I am, this is probably your best bet: Doug's Headers Electronic Cutout It still needs a y-pipe and downturn (minimum), and possibly a ceramic motor shield, so that $240 isn't exactly CHEAP.

I actually managed to locate a head unit in the US already, but if that unit isn't what I expected I'll be sure to let you know. I was just letting you know that someone on here is bound to pick it up

Details on the valve I'm looking at are here: Active Exhausts (check out the Stage 2 kit and the link for more technical info). It's somewhat different to what you're using. They are not a Y-pipe, but a butterfly valve, with an externally mounted vacuum solenoid - which sits a little way from the exhaust. Heat from a rotary shouldn't trouble this when mounted before the pipe goes over the diff, as AES recommends. This system has been tested on rotaries, as AES over here basically specialise in rotary exhaust systems.

That said, I imagine the butterfly valve will still present somewhat of a restriction at wide open position so it is not perfect either.

That butterfly valve has to come off of something and out to another thing to work.

They use INOX "Steel Wool" which is just like Magnaflow's Rock Wool and is not 2000F capable, so regardless of their history, their material selection isn't up to par with the application.

The butterfly actually sits inline in the main exhaust. Flange is welded to pipe either side, then bolt the valve inline.

The solenoid can sit wherever you want off the actuator, then your electrics control the solenoid. Pretty much the same way an electronically controlled turbo wastegate works (where temps are much much higher).

Oh and the INOX steel wrapped around perforated tube wrapped again with rockwool blanket is the exact design SMB used on their mufflers and which were specifically designed in collaboration with Mazda for the Bathurst 24 hour winning RX-7 SP. It is reliable and works. SMB is what half the FD guys on here use as well.

A lot of the problem with mufflers on rotaries aren't to do with the packing material but the actual construction method. As for AES, they are used on Ric Shaw's 24 hour nurburgring RX-7. Pretty sure they know what they are doing.

Magnaflow aren't great at reducing noise (mainly due to small volume) but I had one on a daily driven 12A for 8 years and the rockwool didn't burn out. The shitty resonators gave out way before the muffler.

Not trying to persuade you against your choice at all, just defending a product that is proven.

Ric Shaw definitely knows his ****... I love watching those videos of his at Bathurst.

I went with a ceramic packing material exhaust with 304SS construction. It's just preference I guess. I don't want it to blow out or overheat.

Without a y-pipe somewhere in line, where does the exhaust go? You NEED some separate pipe, you can't just close off the exhaust. That's my point.


Talking with a buddy who will eventually be my business partner at RGHTBrainDesign, I've come up with two ideas.

1) Run a 1-2 pipe (y pipe) with 3" in, dual 3" out off of the downpipe or after a ceramic resonator (or two) with the passenger side running the other mufflers and the valve and straight pipe on the driver side. As for appearances, I'd want to match rear mufflers, which one wouldn't do much to deaden sound... It'd be beast.

2) Put the y-pipe right off of the downpipe and route it into the passenger side fender (cut a hole) for a true side-exit exhaust. Flames would be epic...

As seen here:

That looks like a crazy setup! Look forward to seeing it.

I see what you mean about my idea. Let me explain, the butterfly valve can never fully close - otherwise you'd need somewhere for the gas to go, as you point it. When the valve is partially closed, it is basically a baffle that simulates a stock narrow diameter exhaust pipe. The obvious byproduct of this is a massive restriction in the exhaust preventing the engine from breathing properly. The butterfly valve angle therefore has to be tied to exhaust flow requirements.

At idle and cruise, the valve is near closed. At WOT, the valve is fully open. Then you basically need to tune the curve for opening angles everywhere in between.

A very early version of the product is illustrated in this article (it has had over 10 years of development since then): AutoSpeed - Butterfly Effect

It's a very different idea to what you're talking about.

On a turbocharged car, I can never see that as a good thing. I want as little back pressure as possible, which is why I go from 80mm downpipe to 76mm (3") exhaust.

My three mufflers are all LONG and through-style as to not slow air down. They even have internal velocity stacks and spun louvers to keep the flow rates up. The added exhaust system won't be made at first, but I really like all this brainstorming we've done on it.

Haven't measured it to confirm anything, but well over 8 degrees.

Factory steering is too light in most places, and this should balance things out. Adding steering weight via drift knuckles as well. The tenacity of turn in is incredible. 1/8" steering wheel is a LOT of angle. The factory setup would have twice that in SLOP alone!

Rear Triangulated 4-Link Design

This is designed to react quickly for canyon carving, yet compliant enough for street use where it will be used for Gran Touring and long distance rallies.

Upper Links are Rubber units from MetalCloak.
Lower Links are Heims from QSComponents.
Coilovers are Varishock Double Adjustables, in which I'll add a ~3" spacer to the "head" of the mounting bracket by cutting and welding in tubing. This will give me roughly 21.5" OAL, which is similar to OEM height, while also not effecting the 6.15" travel of the shock. Ride height will be adjustable via lower mount. The 3" extension also makes it so I don't have to cut nearly as much off of the factory shock surround.

Roll Center Adjusted Ball Joints

Next step is to extend them out 1.5" each, as well as add underbracing and bumpstops for my knuckles.
