Shades of the old miataturbo.net all up in here. I approve.

Because torque gives us boners. Rotrex doesn't do that.
QFT. Maybe the banned OP will read this, maybe he won't. That was not a troll, speaking as a 6 year owner of a rotrex.

Someone who has hands on experience with this kit might show up. Or they might not.
I don't have direct experience with the Trackdog kit but I do with the Kraftwerks kit it's based on. With proper engine management and intercooling, it will be basically maintenance free. I tracked mine for ~25 track days and about as many autocrosses without issue.

You need to understand something about this website - the information density here and the general quality of posts here is high because standards are high, and weeding out occurs quickly and ruthlessly. This doesn't mean that every single new user to this forum undergoes a period of hazing. This does mean that every single new user to this forum is looked at closely, and if they are overly sensitive, or full of ****, it's not going to go well. It is true that this forum has a lot of members that like to think of themselves as hammers. If you stick yourself up like a nail, somebody's going to take a swing. If you can't take getting swung at, go somewhere else. Or, here's a thought, don't make prissy douchebag comments that single you out as a collector of participation medals, and you won't get pounded like a nail.

Just chiming in here, as I bought a TDR Rotrex C30-84 kit about a month ago. The kit is the most complete set of car parts I've ever owned. Literally stupid easy instructions in both written and PDF format. It comes with everything, new bolts, gaskets, even thread lock. So it's a very complete setup.

As for why there's not as many supercharger threads and talk here? Well it's MT.net lol.

As for the formula to make a car fast, it's become very obvious that the TSE EFR kit is the way to go. Pretty sure the S1 guys and Emilio made that blatantly clear at GTA. But not everyone has the resources to build motors, and deal with high torque/high heat applications. Hell I don't even have a tow rig setup yet. I chose the TDR Rotrex kit after driving one with a C30-74 and hearing countless testimonials (like above) of them providing bulletproof reliability season after season. I think for those that are clueless like me, a rotrex kit is a better option. Bolt it on, and go for seasons without issues. Also the one I drove felt so easy to drive, and to drive fast. Granted, it wasn't on-track but even so you felt immediately acclimated to the power; NA powerband but just more of it.

*Obviously I'm not saying there's not reliable turbo kits, but on average it seems the most Rotrex kits seems to hold up better on track than most turbo kits for long periods of time. Not to mention the motor stays together for longer due to having zero torque*

I think it's because TDR never really launched the Rotrex product. They started with a LOT of hype and dragged out the product launch date. Last time I checked it was not even on the web site a complete kit.

The Rotex itself had stronger roots with Kraftworks when Oscar Jackson designed the original kit. Internal problems ensued and they parted ways. Those that know Oscar were hopeful for a Jackson Racing (his new company) kit. He was hung ho for it but stronger business opportunities weighed down his schedule. Not sure where it stands today.

The Rotrex itself is a great product in the right application. Once understood and properly setup it delivers strong NA like power curve. It's personality is similar to a race motor with a very big cam.

The Rotrex never really took off. Several issues with belt tensioners and poor Kraftworks support played a role. Poor low end power delivery was another. The strongest appeal was track reliability.

With the latest TSE turbo offerings I can't see the Rotrex making a strong comeback, even with Bill at Trackdog addressing the various issues. I am happy with my Rotrex setup but can't help but admire the TSE turbo kit. I am working on a second Miata build with that kit in mind.

Lastly Savington is right. If you can't handle the humor this forum is not for you!

TDR kit has been on their website for a year or more.

Great points. I think you hit the nail on the head.

I think the Rotrex still has it's place. For someone like me that's working up to NASA HPDE4 and getting their SCCA Novice comp license this year, track and engine reliability is high on my priority list. For someone maybe a bit more experienced, with the resources to deal with some hassles WAY more low end torque provides, the TSE kit is probably the better option.

I'm also sure, from interacting with him on the internet and from having the extreme displeasure of touching a car that he's worked on, that he doesn't know a damn thing about cars.
This is William. I think you're a little confused. First, Gary is the owner and has the TDR Rotrex on his track car and it has been completely trouble free. Secondly, four years ago we had a problem with a customer in which we were blamed of a motor failure when there wasn't even a tear down to confirm or deny that a poor tune would have a rod exit stage left. We still think it was oil pump failure but we were never given the opportunity to investigate. I'd like to think the vast majority of our customers are very satisfied with our work. Look at our reviews on Facebook, Google and Yelp. Unfortunately, that's the nature of things. You can have a million positive experiences and one bad experience and no one forgets.

Regarding the TDR Rotrex, we have been selling them for quite some time now but it isn't just an "add to cart" item. We work with each customer on an individual basis to provide the customer with everything they need and nothing they don't. We also have several customers who track their Miatas with the TDR Rotrex. Maybe the reason people aren't hearing about it is because people aren't complaining! We are a small company of enthusiasts and don't have a have a huge advertising budget or dedicated social media person like FM or Goodwin.

Clint did a review of our product on Miata.net and regularly thrashes it at Road Atlanta.

Another review by Ken. He is more of a weekend warrior on the streets.
