They must be really raking in the cash
If they wanted to compare both set ups under the same conditions why not just set up the supercharger then switch to the turbo set up on one car?

Racing head to head makes a much better show.

Given some of their other series (eg. Miata vs S2000), it wouldn't surprise me if they upgrade the supercharger once it's flogged by the turbocharged car so that they can have a "Round 2".

3" exhaust to 2.5 muffler. NICE!

You have to understand: these guys are amusing, entertainers. They often do really silly things, because they dont know any better and because its amusing/entertaining

At the end of the video they say they think the supercharged car will have the jump and better low end. I just laugh at that because the rotrex does not have that nice low end torque, mostly because it just does not have torque.

I wonder how well they are going to tune the EBC on that haltech. If they set it up right that turbo should really embarass the supercharger all over the place.

A mp62 might have a bit better low end torque then the 2560. But that 2560 should destroy the rotrex all around.

Sometimes when you take two things that are different and you combine them....you end up with the best of both worlds.

The Rotrex is kind of like the opposite of that.

I actually enjoy watching their videos.
But if you don't constantly remind yourself that these guys are n00bs, and most the stuff they do is for amusement, you'll find yourself getting frustrated and agitated watching their shows. What's the point of watching then.

Yet another confirmation that they're clueless on how a centri sc actually works.

We're not learning anything new here, just sit back and grab some popcorn

I have a friend with a NB2 fastback with a rotrex. It is a fun car, I won't lie, but no turbo.

​​​​​​​I am watching the MCM videos just for the entertainment.

I will say though that those charge pipes looked pretty nice. One of these days I will learn how to tig weld and do up a nice set for myself.

Probably because they can't get alum cheap, and don't have the skills and/or the welder to weld it? I dunno.

It's ironic that Australia is one of the world's largest producers of aluminium yet aluminium products are more expensive here than many countries (same for several manufactured products, it's actually cheaper to import DBA rotors from the US than it is to buy them here yet they're an Australian company).

You can weld it with a DC TIG, easier to weld, probably cheaper and it is more stout/durable compared to aluminium in case they rub against something.
The difference in weight is probably less than a kilogram, so if that is your reason I think the level of fael is acceptable. If I would build the same I would also be using stainless.

I think these cars have much more mods than we can see right now, I bet they have changed the clutches as well. Of all the car / tuning shows shown on TV and YouTube I think MCM is one of the better ones.
I remember watching some UK show lately (Car SOS), where they turbocharged a MX-5 and retained the stock ECU with AFM and added a piggy-back of some sort.. That was another level of FAEL.

If you pause the sneak preview at the end you can see the dyno plots from both the turbo and the rotrex, you see the turbo destroys the rotrex everywhere at virtually the same boost level. What a surprise..
