MCNSPORT: Need for Speed D-Mac 86

[MCNSPORT.com]

Some of you have seen this already but its time to do an official build thread with extra pictures

Here is the press release from Speedhunters
http://speedhunters.com/archive/2010/08/...ac-86.aspx

Originally this was to be our Prototype ae86 but then Need for Speed came on board and we decided to build something extra special




We started off with the battered re86....






And we began to remove bits we deemed unnecessary





Until we ended up with as much or a little ae86 as possible



We started by welding up all the holes that would leave tyre smoke or rain water into the cockpit




Then we fabricated the rear strut bar that will be integrated into the rollcage and also the rear chassis bar




We then started to position the centre hoop so we could fab the platforms for it to sit on





We moved to the front then as we had no where to mount our tension rods and anti roll bar so we fabbed a new front chassis section from scratch



We cant wait to show you more, stay tuned to http://www.speedhunters.com for the latest build updates

It's update time !!! The Need for Speed D-Mac '86 is coming along very nicely at MCNSPORT HQ. Let's take a look at some of the interesting details of the build so far......


I wanted a way to be able to add caster to the front suspension without pulling the wheel forward so we got these tops made up and welded in place ... simple but effective!


The scuttle or wiper panel has been removed and the roll cage has been extended to the strut tops and reinforced further with swagged plates. I love swagged plates like these, they look so cool :-)


The passenger side also gets this treatment. Here you can also see the air intake for the heater has been sealed up along with the bulkhead for the AC pipes. No AC in this hachi!


We have started to fab the chassis mount for the track control arms. These should be fully finished in the next update.


The rear end has seen most of our attention. We have decided to go with a rear four link. Three forward facing links and a panhard bar for various reasons. One of them being the position of the fuel cell behind the passenger seat (car is RHD). You can see one of the mounting brackets for the cell in the picture above. Placing the cell behind the passenger seat gives us the best possible weight distribution. Oh and this is only a mock up like arm, the final one will be much nicer.


Here is a good shot of the rear section of the roll cage. You can see the tabs welded at various intervals on the main hoop section. This will be paneled off to prevent Falken tire smoke, water, dirt and flames from entering the cockpit. You can also see how the third link has been integrated into the roll cage and has four different mounting positions for different suspension setups.


More rear end detail; The original Panhard Rod mount has been removed from the chassis and 2 more have been fabbed, one on each side. They are much shorter than the original cos this car will be much lower than Toyota intended or at least the axle is. As with any live axle vehicle, the bigger the wheels you use the closer the axle gets to the floor. The chassis panhard mount remains slotted until the vehicle is dropped onto the floor and the final suspension geometry is done. At that point a tab with 3 to 4 holes in it will be welded over the slot in the correct position. Also we can see the axle has been triangulated for strength, we'll take a closer look at that two pictures below.


This is the rear most structural part of our AE86 chassis. if we bend this we are after hitting hard! The bolt flange you see welded on is just for mounting on our rotisserie but the same flange will be used to mount the removal bumper bars front and rear.


Here we can see the axle triangulation. I don't think this much torque has been put through an AE86 before especially with only 3 forward axle links. So to prevent the axle twisting we strengthened it at its weakest point.


Time to drool! Here are the Work Meister S1's in 17x10 with negative 39 offset. The most gangster wheels ever to be fitted to a hachi ! Big thank you to Work Wheels for their support and enthusiasm for this project


Here is where the wheels would be if they were fitted to a standard car. Out of focus you can see the swagged plate continues from the engine bay up the "A" pillar.


The powerplant is finally at MCNSPORT HQ. A Hayward Rotary built Bridgeported 13B.


Here you can see our amazing MCN / AVO AE86 Rear Coilovers. The best AE86 shock absorbers on the market shall be used to transmit 500BHP to the pavement.


The majority of the roof skin has been removed and will be replaced with our FRP roof skin. The section behind the centre hoop will have a drop vent to provide air for the rear mounted radiator.


Our WRC inspired roll cage is now fully finished


This swagged plate is just awaiting welding in to complete the strengthening of the floor mounted axle link points


The new disposable rear is ready ahead of time. It's a complete clam shell style mould of a JDM spec ae86 rear with tail lights and all in place. This will make wall rubbing inexpensive and quiet spectacular but best of all panels can be replaced easily between runs.


A nice stack of Work Wheels ready for Falken Tires and some serious abuse

Just a quick update for all you Speedhunters ! We are in a bit of a transition period here, most parts have been mocked up and are away being machined (or moulded in the case of the FRP) so let's give you a small run through what we've done before we do a much larger update in a week or two ...

As you can see from the above picture, that is a very odd place to have the steering rack in an AE86 but that's where it now calls home, right in front of the 13B motor.

Also we have cut the bulkhead or firewall on the drivers side (RHD) and that is mocked up nicely but without having our transmission back from being machined we cannot install the motor and finish the passenger side so that is cut roughly for now.


I really love this aerial shot from upstairs at MCNSPORT, you can really see how short this thing is from wheel to wheel. Oh and also our custom roof has arrived !


Here is how we attach the 13B to the hachiroku. With the motor mounted back and our front steer system it should give us the best possible weight distribution. Also notice how one tube is straight and one is at an angle. All will become clear once we update you guys ...


Speaking of weight distribution, here is the intake that feeds our rear mounted radiator.


Here is the front of our roof. These intakes will also supply air to the radiator and some much needed air to myself while driving / holding on. This thing reminds me so much of an old Group B rally car, I love it!


Okay, here is the mock up of our front suspension system including the new steering bracket. Yes, the steering is now worked off the front coilover.


Like so. The slotted hole be changed once we map out everything at ride height.


Here are the coolant pipes protruding through the bulkhead ...


And here they are running through the cockpit on the passenger side. Passenger might get a little warm in this car ...


A big, big thank you must go out to Carbonetic who supplied us with a Carbon Twin Plate Clutch. These are just a beautiful piece of kit.


Sytec have this sweet bracket for the Bosch 044 pump. All Sytec products are available at MCNSPORT


And finally another shot from above as the fabrication process gets closer to being complete.

There is a lot of crazy things being done to this car and that's what we wanted, to build something away from the norm like those glory days of Group B rallying. It looks like Europe is the only place we could build such a project now with the new tire to weight rules being imposed by Formula D
