That Rotex looks like a hydrostatically driven turbine. Maybe it's a smaller unit that runs at much higher rpm?

I believe the answer is yes to both of points. Sort of a turbo-esque supercharger? Anyway, I don't have any feelings either way but was simply curious why this unit hasn't been considered/installed by the 80 crowd!
 
Probably because it's unproven here in the US. The story I got was the Sprintex blowers are much more efficent that the Eatons in the TRDs. Lower heat gain & less HP rob. The guy I was dealing with advertised 100degF cooler exit than the Eatons (but I haven't seen any proof mind you).

Personally, I am interested because I know TRDs have issues with OBD1 80s (some will argue this), so I thought it would be smart to at least try another.

Whoever takes the plunge and tries one, I'd love to see before and after dynos with temp/AFR readings.

I am always interested in new tech, even a lot of stuff that I am not planning on using for my own rigs. But, this looses a lot of credibility with me right off the bat when they make a claim of 100 degrees cooler. On an average 100 degree day here in Phoenix, the intake temps below my TRD S/C run between 140 and 160. So maybe I should use the Sprintex as an air conditioner??

A friend of mine has had one fitted for over 12 months now and apart from a ground wire falling off (which effected the piggy-back tune), it's going great. Pulls like a train compared to my n/a manual - he's boosted and auto.

Soon as I have some money, I'm getting it done. I'm not keen on some of the castings, look a bit daggy, but I'll polish 'em up and the mounting bracktes are works of art.
 
I'm really interested in taking the plunge as well, but I'm also considering the Rotex units...

Hey wait a min, you're in my hood and I don't even know ya? Post up in the High Desert Cruiser section of the clubhouse and introduce yourself!

Sorry for the hijack!

I'm here, but my truck's still back east. Being that I'm moving again around the end of June, I haven't decided if I'm gonna bring the truck out here in the next month or not. If I do, I'll be sure to stop by and say hi :)
 
So it looks like Sprintex gave up on the poor communication (actually complete lack of communication) from their distributor at Bullet Cars, and now actually lists a contact shop/distributor in the US: http://www.sprintex.com.au/sprintex/contact-atg/united-states/. I called, but got no answer. So I fired an email over to 'em. We'll see if I get a response from these guys.

They also finally updated the Bullet Cars website, and included info on their exhaust upgrade: http://www.bulletcars.com/parts/engine-parts/bullet-ultimate-exhaust.html#bulletult1fzfe. Not sure how this fares/compares to EMS Powered's Exhaust System: http://www.emspowered.com/storefron...20_121&zenid=ee42fb9c5a432396cf07455994cb1516.

The other real big question I have is, if the Rotrex Superchargers are all they're hyped up to be, is it worth trying to do the above application but utilizing a Rotrex unit?
 
I'd love it if someone would install a Rotrex unit in their 80. It sounds so uber cool technology. Looks like this unit would work for our 4.5L engines. Additional 118hp was gained for the FJC install it appears.

Ali, the prob is a) I doubt a company that SELLS superchargers (Sprintex) would sell me their kit without the supercharger itself, and b) I bet there would be *significant* fabrication work necessary to make the kit work with a different supercharger.

The other option would be trying to fab all the piping etc from scratch ($$$) and just buying the ECU from them.
 
I would like to see these guys make a kit for the 1FZ. They seem to be pretty popular with the Subaru crowd. Again from the land of OZ!

If the TRD supercharger doesn't require much in the way of ECU stuff, would the Rotrex require it? I'm guessing that the Rotrex puts out more than the 7psi that the TRD puts out?

Fabricating the mount for it doesn't look like too much of a big deal and the plumbing is equally straight forward. Looking at all the Turbo threads and their piping makes the piping for a SC simpler to me.

I'm like VERY (like 100%) serious about doing this, if I can get the parts I need and it'll make the power gains I want. The truck is just S L O W. And it's really gettin to me lol.

Who knows, maybe I can work something out w/ ACC to make a bolt-on kit using a Rotrex unit? ;)

The Sprintex kit doesn't require it either, but to make the SIGNIFICANT power gains they claim - double what the TRD makes compared to stock (50% vs 25% more power over stock), the ECU w/ more aggressive mapping & additional injectors is definitely a requirement I'm sure. My biggest issue is, is that an add-on chip, or a complete replacement? Cuz I don't wanna lose my ability to throw codes and reference them like the OEM ECU provides you with.

Nope. From their website: http://www.bulletcars.com/superchar...re-6-cylinder-1fzfe-supercharger-system.html: "Small boost levels of only 5 psi allow the engine to comfortably perform without stressing internal components, whilst delivering exceptional power and torque increases."

Hope so...
 
Wow, only 5psi to gain 118hp on that FJC linked above? Dang!

Wait, Sprintex is different than Rotrex or am I mistaken? Your link above is referring to the Sprintex unit doing 5psi. Do you know what does Rotrex puts out?

I know of no Rotrex 80 kits. So I have no idea what they run at or the power they make. But they're *supposed* to be much more efficient while making more power...
 
By the way A new batch of TRD supercharger kits have hit the shelf.
