I think Moss is going to continue to sell the M45 kit.
That is the direction Oscar Jackson and son are going. The M45 is still being produced by Eaton and sold by Moss. The Rotrex will start out at around $3500 for a 5 psi kit according to a phone call I made to JR hq's.
From what I have heard... Several years ago, Oscar Jackson sold all existing Jackson Racing intellectual property to Moss, and licensed use of the name to them. He stayed on board with them for a good while running things, and then left completely around 3 years ago to retire in Colorado. Since then, his son (Oscar Jr) graduated from college and decided he wanted a tuning company. He talked dad into starting over and they have developed several new products in conjunction with SUMMIT INDUSTRIES. I believe Summit is a part owner/major investor. It appears that while Oscar licensed use of the name to Moss, it wasn't exclusive rights. I don't think Moss realized this. They had no idea he was starting back up under the same name until he had hijacked jacksonracing.com out from under them. Moss has designed several new kits on their own since since Oscar left, and will continue to.
The Rotrex blower is kinda cool looking!
It is a centrifugal supercharger, which many consider inappropriate for a small engine. They typically build boost in a linear fashion, adding little boost (and therefor little torque) at low RPMs. Information on the Rotrex site (as well as a dyno I saw of a Honda with a Rotrex) imply that the Rotrex deals with this much better than other centrifugal superchargers. We won't really no for sure until we have a dyno from a Miata running a Rotrex so we can compare the graph to that of other FI Miata kits.Quote:

Active Autowerks in Miami (one of the biggest FI kit manufacturers for BMWs) has been making a kit for the E36 6-cyl cars. I don't think anybody was really impressed with the performance or the ability to run more boost in the future.

People weren't happy with the centrifugal options like the vortech and rotrex so AA developed a twinscrew kit.
What's with the Borg-styled header?
::Paul::
It uses slip joints that allow for thermal expansion and the springs hold them together.Quote:

Although depending on the price and performance I might be willing to sport one on the RSX. I think the one in the pic is the Fit/Jazz model.
It's even made out of titanium.

Don't you guys remember the rotrex from 2 years ago? It was hyped up for the 350Z. I thought it was sweet when it came out then. It doesn't appear that HKS thought the same, according to their website.
Here is a review with dyno #'s and pics from turbo magazine's website.

The yellow bolts are pretty...
I thought it sounded familiar.Quote:

The only advantage is space.
In this application, what are the advantages of ether?Quote:

Eh, guess it depends on the setup and application. I know of a few C4 vettes that have centrifugal superchargers making a pretty reliable 600 rwhp with no major problems. Of course with a v8, it doesn't need much to make a lot of extra power, but still. May not be the best but not necessarily the worst.Quote:

It's not neccessarily about peak HP/TQ numbers but the area under the dyno curve. A centrifugal supercharger will never give you the low end torque that our small disp. engines need. That's why the roots and twinscrew superchargers are more desireable.Quote:

Depending on the application, I don't think one option is completely inferior to another. Yeah for small motors it isn't the best choice, but works great on other cars. You have to go through hell to get turbos or a roots/screw supercharger under the hood of a C4 vette. I just threw in my ::2Cents:: about the apparently much loathed centrifugal supercharger so whoever asked about it will not think they are as good as a Vtec sticker on a Honduh.Quote:

lol, sort of...I was the camera guy for a handfull of the vids from the old Racing Freaks site. This one guy had a nice 600 something hp Supra with not too crazy body kit and uber-expensive cool wheels but he couldn't drive the damn thing with the crazy ass power curve it had. He'd have to do 70mph rolls in order to try and beat cars with 100 hp less. An opponent would put several cars on him then he'd hit boost and gain back half, then shift and loose several cars...hit boost and gain a few more back then shift....:punchout: I think his best 1/4 mile time was a 13 something at 140mph! Great mph but hell you can make a 200 hp Mustang (the old 5.0) run 12's or lower with just slicks and/or gears.:rolleyes:Quote:

sounds like that supra guy needed to do some tuning (or it was his first time driving a stick). i would think that he was in the minority in the high performance supra crowd. Meaning you aren't going to find very many supras like that. Most of those guys are pretty smart cookies and are going to do their homework on what it's going to take to make a certain turbo setup work well for them.
also. i realize that supra's have a bit of a rep but think about what your comparing. supra's came with a 3liter with little less than 300 hp or so. and a vette (depending on what year) came with an almost 6 liter 400 hp or more motor. so if you now have an almost double horsepower supra it's gonna take a little work to get the tuning sorted out. i guess what i'm getting at is "give 'em a break man"
You've heard the old joke haven't you?
What do 400, 600, and 800hp Supras all have in common?
They're all 12 second cars! ::Banana::
92-96 Vettes only had 300 hp and 340 tq. The 96 LT4 performance option had 330 hp. The C5 Vette in 97 had 345 and didn't get to 385 til the Z06. So not quite the advantage you think. The 06+ Vettes come base model with 400 now, though and is underated according to a few friends.Quote:

I was going to add that joke into my post before... but it's dependent on the driver too. There's quite a few 9 and 10 sec Supra's out there ;) There's actually a new MKIV club in DFW that showed up for HIN, I spoke with a couple of them when I was assigned to position cars for the show. Some of them were pretty impressive in the mods dept., one guy rolled in running on C16 ::Banana::Quote:
