Jackson Racing Rotrex race kit proto
#23
I have no interest in expanding my mechanical abilities, its my driving abilities Im looking to improve.
Are you interested in a kit 2k? I seem to recall reading that you got burned years ago with the KW kits and their 'pending' CARB EO.
Im not looking to be a master mechanic, nor ultimate power, I just want this thing installed for some spirited driving and to be problem free. We'll see how it goes.

If you have a basic automotive tool set and can follow instructions, you can install this kit. As always, we recommend letting a pro do it. Preferably one that knows Miatas.

Sure. If someone gave me one I'd run it and give honest feedback. But that's not going to happen.
Yes, its in my other thread. I don't need to crap up this one with more of that nonsense.
Jackson Racing certainly seems to have their **** together this time around. The ones I saw running at MRLS over the weekend seemed to have no issues. The mounts look far more polished than what KW was selling. The Jacksons as an independent entity seem like pretty solid people, not sure why they got caught up with Group A the first time around.
Regardless, when should full production kits be on the market?

Having seen the car fairly intimately, and checking out a few others with the carb-legal kit, yeah - it's something anyone can do with real effort. It's just the right level that you'd learn a lot but be able to pull it off. Probably 40% the work of an FM-II, 30% of their old kits. :-)
There was an overwhelming sense of reliability in it. Not sure how much of that came from the fact all the people I saw running them knew how to build solid running cars in the first place, but it sure LOOKS like 5 bolts to glory when it's done. Very clean looking, VERY linear power.

I installed mine while doing my first ever timing belt. Both were my first automotive procedures substantially more difficult than an oil change. With a modest collection of hand tools and an ability to read and follow directions anyone can install a rotrex.
I mean, it's not a lego kit, but you can see everything that needs to be done when you open the hood of a rotrex car. It's all right there.

My goal is to make 200lbs at 3500 and maybe hit 250 peak. I think it'll make 320whp on top.

A 250tq peak would be nice to have. I don't know what's holding me back from that. The ebay tri Y header or the skunk2 intake. My bet is on the header.

Any updates on your own implementation of the JR Rotrex kit? In terms of midrange boost/torque, and how you see it as long term solution for track-Miata under constant 30 minute full load?
Wonder if the blow-off valve is working as you wish, and if you see any opportunity to make use (recirculate?) of the bypassed pressure, or maybe see opportunity to slow down Rotrex at Redline to maintain boost and maintain compressor speed (without expensive gearbox)?
How you see this option compared to K24? You seemed poised to go that direction originally upon announcement of the idea/kit, but since the successful racers seem to have lost interest in engine swap. Is it the newly developed head porting that gave Miata new lease of life? or?

The JR Rotrex works perfectly on track. I assume your question pertains to a decision you are trying to make between a K, turbo or Rotrex for track use. The Rotrex solution is the least expensive and easiest to implement.
Our BOV set up works as intended and previously described. I know of no other method for limiting peak output that is as efficient. A simple restrictor is easier to do but provides less precision and is limited in how much boost can be capped. IOW, you can't choke 100whp worth of flow with a restrictor without unpleasant repercussions in charge heat, drag on the blower, etc. The CARB kits will be spun well below blower redline and use a restrictor. The 300whp implementation in Deviate can run max blower CFM and bleed boost down to 220whp on pump gas without any problems.
The OGK (no windshield) will get a K20 with a C30-94 for about 400whp. For no other reason than we want to try it.
