What was Mazda's "factory team?"

I don't recall exactly what cars they had, but there was a huge Mazda truck with a huge tent and they had two Mazda 2's and two MX5's, IIRC. Maybe William or Emilio know what numbers and classes they were in. I think that one of the 2's and maybe one of the MX5's were in our class, but even if they weren't, unless they were in ES or running the 6 hour, we finished ahead of them. Though regardless of where the "Mazda" team ended up, it shows what great cars they make that more than half the podium spots were filled with Mazda's, and six of those spots were for ES and ESR for which no Mazda really stood a chance.

No interest in NC market. I leave that to Goodwin and refer folks to him several times a week. Ironically, we offered Brian a spot on the driving team but his planned vacation interfered with T25 scheduling. He was pretty bummed he couldn't make it. For those that don't know, Mr. Goodwin is a very quick and experienced club racer.

Seats are filling fast so if we still have a spot for him, he's on.

The awesome tracks are plenty close - you're the one who is far away. :giggle:

Sounds like confirmation of a 2012 race

Agreed. Only three hours away, on a plane, because they are in Texas.

When did Big Willow and Infineon move to Texas? :giggle:

Four letters.... C O T A




Assuming they cease with the drama and finish construction...

Agreed. For a centrifugal compressor, it would take something like a variable drive ratio, or perhaps active control via a throttle by wire system with torque output feedback. Either way, not simple, not easy, not practical for a DIY installation.

So now that you're not hooked up with someone dealing Rotrex anymore, you're going to push turbo's? Am I the only one that see's the irony in this?

I wouldn't call it irony exactly but it is a little odd. I think that it has less to do with the product and more to do with Kraftwerks. I am interested to see what happens to the rotrex system in the coming years. I know that the Jacksons are still working with them, so I would expect things to happen at some point.

As for the rotrex units, I have never heard anything bad about them from anyone at 949, but for the specific classing for T25, the rotrex just doesn't make sense. If you could maintain max revs all the time it would work, but at the 25 you want to be able to short shift and/or just leave it in a given gear without losing too much speed. A rotrex just doesn't have enough down low to justify it when there are other systems that could do the same job a little better. The only way I could see a rotrex working is if you were going for modest power goals and running a bigger blower and capped max power at something like 200hp over the whole rev range.

I would assume that had Kraftwerks not imploded on itself, 949 would still be using and pushing them. Emilio isn't in the habit of selling products that he doesn't like.

that's uncalled for. I was the one who ran rotrex for 2 years. I loved it, still do. but you have to look at NASA rule. it is LB/hp. it is based on hp, not tq. so you can have unlimited torque, but are capped on hp. heck, I would run a diesel if it make financial and business sense.

your statement is also untrue. Jackson Racing (both SR. and JR. were on the team) is still working with rotrex.

if NASA rewrite the rule tomorrow that is based on LB/tq. then choice would be different again.

Yep and then everyone would be trying to build F1 motors or adapt motorcycle engines :giggle:

Yeah I know. I'm going to do my best to get down to thunderhill and laguna next year. If the budget calls for it I may try to get down to so cal for one of the supermiata events.

How does your choice in modifications change what I said?

I understand clearly why the choice was made, I just find it to be contradictory after reading previous posts downplaying turbo's because he sold rotrex kits.

Can you find one post of mine where I clearly stated turbos are not suitable for track use?
You can call me many names but hypocrite isn't one of them. I am still a proponent of the Rotrex because everything else being equal... they are still easier to make bombproof for racing, make more peak power for a given pressure ratio/ CFM, create less thermal load on the oil and coolant per hp and deliver superior BSFC. The downside of a Rotrex based system, as everyone knows, is their linear boost rise and correspondingly inferior torque under the curve. This torque curve deficit can be worked around to the point that the differences are small, as we were able to accomplish on William's 230whp, 10psi time attack set up a few years ago. Maybe someone can post that dyno.

As a few people have clearly reminded those reading this thread, NASA PT favors maximum area under the curve. That's how Crusher was built and how we will build next years car. Vendor affiliations are secondary to the goal of winning. Rotrex's still kick ass, just might not be the right tool for the job in this case. The door hasn't closed yet though. We may run a car with F/I next year, if so, it would likely be a Borg EFR, but it could also be a Rotrex C15-60.

Well said Emilio. Whatever way you go Im sure its going to be badass and done right.

C15-60? I thought the concept was to run a huge rotrex, restricted down to desired HP level, and have the power hit early, then flatten out. What am I missing?

A C15-60 on race gas with a purpose built BP engine would need to be significantly restricted to meet our targets. But we're way ahead of ourselves in this discussion. Not real likely to run one, just not discounting it completely yet.

When you want to take the training wheels off and go to a big boy tracks let me know.

I look forward to see how next years car progresses. I foresee interesting developments coming in 2012.

I never called you a hypocrite and downplaying turbo's because you sell rotrex kits is very different than saying that turbo's are not suitable for the track. If I am going to spend time searching for these posts, let's at least get on the same page.

Let me guess, you guys will use a TrackSpeed turbo kit on the next car. ;)
