Mugen MTC1 Wiki:

MTC1 Manual on the Mugen Web Site.

Correction for the manual




The max/min tooth count of the spur and pinion combined.

64p = 127 to 164 total teeth


48p = 95 to 120 total teeth


People who have spare spur gears left over from other cars which they wish to use but can only utilize 2 of the 4 mounting holes, here's neat trick from MKAH to drill 2 more holes precisely in the spur gear:

1.Dismantle the Spur Holder and mount XRAY Spur with two screws.

2.If you have take a 3mm Top Setting Screw

3.Get the Top Screw in the first free thread to the Spur Holder from the other side until it touches the Spur a litle bit.
Make the same with the second free Thread.


4.Dismantle Top set Srew an the two screws witch holds the Spur on the Holder.
Now you see two marks absolutely central.


5. Take an 3mm Driller an Drill the holes at the marked places

6.Mount the Spur with the two old and two new holes on the Spur.


Spur Gears known to fit the gear holder with the correct hole pattern

1. Axon
2. Panaracer


Upper front arm hinge pin set screw tip (or any of the kit set screws):

When installing the set screw run the set screw in until you can see it come into the hinge pin gap. Back the screw out and make sure there is no flashing in the way and then the screw. Now slide the pin in and you should hit the pin and come to a dead stop. It will be a solid feel and not sloppy like it will not tighten which is caused by any loose plastic.

It's going to? It sounds like you're saying all spec racing TC's need 40T. At least, Serpent doesn't offer 40T (not even sure how many teeth the pulley has TBH) conversion.

The Yokomo is fast in spec classes...

I get that but my question is do you know for sure that it is fast because of 40T conversion? If that's the case, why wouldn't the other companies offer 40T, or is there?? Has Yokomo been winning all stock races all around the world then?

I don't think mugen would of shot themselves in the back with making a car just for mod u know seeing as it doesn't have the 40t conversion you said that would of make the car fast right .

I wasn't knocking on the car, it's on my to buy list. This thing probably went into manufacturing production before yokomo made a switch back to 40t with internal gearing of 2.0 instead of the 1.7 ratio. The 1.7 ratio in stock racing we had to run slightly larger spur than usual to get the needed FDR for stock racing. There's other added benefits with using the 40T. Anyways I don't think they shot themselves in the foot, the 34t is still decent, truth be told if they decide to go with 40t it will give the car more tuning options. The earlier pictures of the mtc had yokomo belts also.

The teeth count on the front and rear pulley. Stock comes with 34T pulley which is really small and probably work best in boosted stock or modify class.

When you increase the pulley size your have more torque transfer to the wheels which makes it easier to rocket out of turns.

Yokomo has been doing very well in stock after swapping back to 40t, as a mater of fact in every class they're running the Bd8SV. Also most current platforms are running 38t and 40t, internal FDR 1.9-2.0

Im sure its not too hard for Mugen to come out with a conversion. They just need to make a 40T pulley for the front and rear spool and new belts to go with it

Their spool&diff arrangement gives very easy option to change pulley sizes. One small - identical - plastic part from and rear. No need to design (and have people buy) a whole new spool / diff casing.

But will the larger gears fit in the bulkheads?

You don't get any more torque once the pinion/spur is selected to give the same FDR. The reason larger belt gears are advantageous in spec classes is because the belts don't bend as sharply, which improves efficiency. The more the belt flexes, the more energy is lost as friction and heat.

And this is why if you have been in this hobby for a few years you learn never to buy the first run of a new kit! Wait a year and all the potential flaws will be found out before you waist your money!. Love the looks of this car though.

It was my understanding that it didnt matter much as well, but was told differently by others racers at the track. When they saw the MTC1 and looked at the size on the pulley their instant reaction was "oh this car must not have much torque"

Belts not needing to bend that extreme sorta make sense, but not sure how significant the effect would be. I guess the results from the yokomo speaks for itself :shrugs:

Looks like 1-2 teeth would be fine. Any more and shock towers would likely need to change (but then might be poking out the chassis)
