I just Got my 1986 rx-7 GXL, i dont regret buying it at all! It came with a factory replaced engine with 29,000 miles on it, a rebuilt trans, Tokico Struts,springs, CD changer and a custom TARGA TOP!
Anyways i was just wondering what different supercharger kits there are for fc's i've already seen that Camden kit and i'm not so sure on that for $3700, i've seen people use Paxton superchargers but haven't found how or where to buy materials to do that
Is it even worth supercharging, or would a turbo work better, keep in mind its an N/A car and i'm slowly learning how to work on my car, partly thanks to this Site
Check out my car and the tons of pics of it on CarDomain.com
heres' the specific link http://members.cardomain.com/redrotary7
I think i did a good job of researching and studying all i needed to know to get a good fc, not bad for my first car. . .

 

Very nice looking RX-7 bro. I myself am currently working on a super charger kit for the FC N/a's. I would tell you to visit my site for more info/questions but it is currently down for an unknown reason. hopefully after my ISP gets its act together we can give you some info on our product plan. Otherwise PM me for info.

A super would be cool just to see the low end it gives you however alot of people it looks like are going with turboed n/a's witch shouldn't have that much more lag (none) than a supercharger due to the high compression rotors.

 

We hope to undercut that trend for people looking for low to medium boost by providing a "kit" to bolt in and setup for under the cost of turboing your N/a. I'm optamistic about this product's future.

 

I'd say optamistic, that's a rather lofty goal. I want to see pics of the intake!

 

With the current construction and machinning costs I don't think its that optamistic at all. We should be able to provide a kit for WELL under camden's unit.

very cool! If that where possible I think the product would have a great future.

 

It all depends on what you want. If you want to go fast, have greater power potential, go with the turbo. But if your like me, and want the power on tap at normal around town speeds, and just want your car to be much faster off the line, go with a supercharger. they both trade off evenly. I just know that i would get tickets like crazy with a turbo car, because you have to really get on it for the turbo to work.

Yea, I planned to keep this more of a secret until I was done but apparantly my hands(ones typing this) didn't think I was in charge here.....

 

interesting targa top

 

indeed

 

nice car . love the targa top. it be nice to do one day if i knew how

 

More pics of the targa top? Looks very interesting. Never seen one on an FC before.

 

yeah i think i'm the only targa fc around it seems, and i love it, tops a little sketchy but i dont mind, its a trade off really i'll post more targa pics on my cardomian page, since its a pain to do it on here

 

i just want to kill every honda at pulls up next to me acting all bad, i HATE that, hondas i mean

 

A turbo would work better. There are really only two advantages to a belt-driven supercharger on an RX-7:
1) It's different.
2) The "feel" of the car is more positive because boost is directly related to engine rpm.

Other than that, a turbocharger setup is usually less expensive, offers a wider boost profile, will yield more power for a given boost level than roots or lysholm superchargers, is less prone to detonate than roots or lysholm superchargers, is easier to intercool than a roots supercharger, and will create boost faster than a centrifugal supercharger. A modern ball bearing and/or sequenced turbo will also create boost at about the same point as a roots or lysholm supercharger.

False supercharger "facts':
1) They create instant boost.
2) They give the engine more torque than a turbocharger would.
3) They are less expensive, less complicated, and easier to install than a turbocharger.

 

Thanks for the info, anybody know of any cheap exhaust to turbo manifolds for n/a fc3s'? or am i going to go back to my old highschool shop and make one, oh wait they dont have a mandel tubing bender, damn. . . .

 

staticguitar313 would you be willing to give away that rear smoked out cover you did for the tailights???

Very cool targa top - I've never seen one before, although I've had ideas run through my head as to how it could be done.

 

sorry i brke that plexi cover taking it off the taillights, and i dont regret it ,sure you can have it its snapped into about 5 peices , local pickup only

Listen to this man. Even though I can only enjoy my car right now below 3000rpm (bad injector clip, wrong heat range spark plugs), I've put a few miles on my supercharged RX7 and it's a whole different animal. Low end acceleration is vastly changed. I simply plant my foot in third gear and before I can really even think, the car goes from 25-40mph.

That being said, AaronCake or SonicRat's cars (NA-T conversions) are faster than my car will be. NA-Turbo conversions, however, are more work because you have to do some fabrication. Turbo cars will be faster than supercharged cars so long as they're properly managed. If someone makes a turbo kit for the NA RX7s, that would probably be easier installation-wise.

Superchargers are just about power delivery. Torque is probably the same, and my car is not hitting max boost whenever I plant my foot down.

yeah I saw a camden kit put on a gxl. The driver talked **** that he was probably getting 275-290 at the wheels. He duno'd this weekend and got 189rwhp. And the car sounds like its twisting so hard under boost that the motor mounts are going to break and the engine is going to jump out of the hood.

Sound effects = 400rwhp
Actual effect = 2500 dollars and 29hp

 

The easiest solution (with less fabrication) for an NA turbo would be to rebuild a Turbo engine and use the higher compression rotors.
