Anyone tried a procharger on there RX-7??

Check this out at procharger.com. A belt driven turbo charger, you can even get one with a intercooler. But can you put one on a rotary, if you can, I want one for my na!!! For around 2,000 dollars, you can get a procharger with a intercooler. Does anyone think it's worth the money??

Its a supercharger

I'm not that familiar with ATI, but I'd be wary of anyone that makes this claim:

"Intercooled ProCharger systems also feature none of the maintenance of other supercharger systems, as air-to-air intercoolers are 100% reliable, and mean that you don't have to worry about ignition retard, auxiliary fuel or water injection systems which can fail."

That is total b.s. If you add boost to an NA car, especially the amount they're talking about, you will have to add more fuel.

My friend was gonna get this for his 95 SS Camaro, and i asked him what kinda fuel upgrades he was gonna get. He said it would produce a 65% gain, bringing him to 515 rwhp, i laughed.

He said he didnt need any fuel mods, and i said i would laugh when his engine went bye bye

sure he doesnt have apex seals, but he's got 100 other parts that can break from detonation

If he's really a friend, give him another warning. If he's going to get a 65% increase in hp, he will only get it once. Then he'll burn all his pistons from the detonation, and possibly break a connecting rod.

If he's not really a friend, sit back and watch the fireworks.

It might be worth the money... but most of that is BS. You WILL need to do fuel mods. You MAY need to retard timing. If it's belt driven, it isn't a turbocharger, it's a supercharger.

Well I actually been thinking about duel belt driven pro chargers into stock weber 38mm carb with intake 2 ports(street port). I was thinking one pro charger to each port..? And maybe I might blow up this stock motor but imma try not too

The important thing to know about rotaries is that carbs are **** for supercharging. Not only are they impossible to tune efficiently across the rpm and boost ranges, but they have a Venturi (restriction) that decreases pressure (boost). To quote directly from Corky Bell's "Supercharged!" book, "No one can go fast on a fuel system that is not calibrated correctly, and no fuel system in existence can be calibrated as accurately as modern electronic fuel injection. For this reason, EFI is the only fuel delivery system discussed in this book."

The important thing to know about centrifugal superchargers is that they produce boost at the square of rpm, which means that they don't make max boost until engine redline. It's like having permanent lag. The good thing is that the lag is linear and completely predictable. Since there is little to no boost at lower rpms, the car is easily driven on the road or autocross track. The downside is that a comparable turbocharger will offer better performance in every other respect.

The main reason you don't see blowers on imports is because a supercharger takes power to make power. Most import or tuners have small motors which n/a have low power, which is why turbos are so perfect for them. Prochargers sound awesome though, please keep us up to date if you decide to build a Procharged rotary.

I will I planned on putting a t4 turbo plus both prochargers

Please state what you are trying to accomplish. That is not an efficient twincharger combo, so I am pretty sure that I can help you choose better components.

Well my goal is to have unbelievable high end torque and quick ness to it so t4 turbo for first 4 thousand rpm and at 4 rpms the pro chargers will kick in ! I want to be able to drift or drag race depending on how the body's set up that day

That's backwards, the supercharger kicks in first, the turbos, later.

If you want a Swiss Army knife of race cars, the closer to stock, the better off you are.

That is waaaaayyyy overkill and extremely complex and its gunna be a nightmare to get running. You will not be able to effectively run a turbo and 2 prochargers, not bashing but it doesnt make alot of sense either. If you honestly want to do a procharger and turbo setup run a small charger and maybe a gt35r or gt45r ball bearing turbo to help spool it. But if you want the best top end just run a bridge and a huge bb turbo. If your up for that venture by all means hit it full force but it will be highly involved and lots of money will go knto tuning and the fuel is going to have to be huge also. Good luck man.

Yeah, I think what's going to happen with that setup is that you will have the lag of the turbo at the low end, and the drag of the superchargers at the high end. It will be heavy, complex, and a pain in the rear to sequence.

A better solution is to use a twin-screw supercharger. You will only need one, and it will give your engine low-end boost with basically no lag, high-end boost with minimal heat rise, and very linear power that will make the car easy to drive (no downshifting for power like with a centrifugal supercharger, and no sudden turbo boost that shoots your car into a telephone pole). It will still have mechanical drag eating away at the engine output just like any other supercharger, but at least it is only one supercharger rather than two. The only real downside is that it doesn't work well with an air-air intercooler, but an air-liquid intercooler and/or water injection will work fine.

I am not aware of anybody on this forum documenting a twin-screw supercharger project that was successful, so your car would be very unique. It is not an easy project, but it would be easier than the one that you originally proposed, lol. I recommend getting a copy of Corky Bell's "Supercharged!" book in order to see what is involved with installing a custom supercharger, and below is a list of some of the twin-screw supercharger vendors that I can think of off the top of my head. While the book will help you with choosing a supercharger to match your engine, I still highly recommend that you talk to the vendor before ordering one.

That would be the case for Roots type superchargers, but not for centrifugal superchargers.
