Announcing My Supercharger Project, It needs a name!!
Had a custom duelie built for my SP 12A once by a V8 shop. Cut my RB header & welded 2 Dynomax muffers on & 2 glass packs to the tail. When I got on it, it was EAR-SPLITTING. Tried a few other combos. Had to wear ear plugs to drive to work till the RB system came in.
yeah i really need some helop decidin on the muffler, Everyone says the racing beat one is too restrictive. I want something that looks nice, but doesnt sound all raspy! no fart cannons!

Go ahead with Project torque. Mine is Project GSL-SC M90 thinking of using a M series 'M' with a 90 after that..

Well are you in for a big surprize Matt. Today after putting in my new tranny I went to Atkins and put on the new and improved blower. My pulley was not changed and my boost is now at 10lbs. I am impressed big time. I thought my car was a tourqey thing before the change but now....OMG you are going to **** when you see my car next.
I must say that Atkins "Camden" has out done themselves on this one.
Im dynoing it as soon as my tranny is more broke in.

If the atkins new version of the camden chargers are doing that much better, then im just STOKED. Apparently the smallest pulley they make will now allow for 17PSI!!! Will that even work on pump gas? Guess we'll find out...
Im really excited about this project, mainly because I beleive that people gave up on the Atkins charger too soon (or so it seems). Ide love to see it at its full potental.
well i just have a question (im not trying to diss the idea of a supercharger cause i know how wicked they can be) im just wondering why would you put a supercharger rather than a turbocharger... I have read on the Camden sight that you feel the instant boost of the supercharger in the low end but turbochargers have lag and are for top end... But correct me if im wrong but rotary's are ment for top end... they love rpms so why get something that boosts the low end instead of the top end? Wouldnt boosting the top end have more potential (im new to this stuff im not trying to hate im just trying to learn =) since you guys have probley researched the crap out of this i would like to hear your opinions thanks)
haha, tear his head off why don't ya! but seriously its been debated a ton, so i wouldn't take it the wrong way.
And about that 17psi pulley...holy crap thats some good boost! BUT...that air charge would be on fire, just asking for detonation, you would HAVE to have some sort of intercooling, or maybe water injection, but i would love to see some numbers on that.

First and formost we will be adding a 7" CAMDEN supercharger along with:
What are you turbo guys running for mufflers? Ive heard the racing beat one is too restrictive. Any suggestions you guys have or ideas u have for the project? I havent gone into the extras that are gonna go with this such as gauges and all that, but it will be there!
Stay tuned, because I will have a comlete set of videos and pictures, and time slips and dyno runs come summer to show it all off! Im aiming for 12s here, but well see!
This thing is gonna be a torque beast!

- A S5 TII block, large streetported 3 window main bearings, oil pump mods, 3MM Atkins Seals
- S4 water pump and housing
- FD alternator
- ROTARYSHACK weber 48MM DCO carb
- Centerfoce Dual Friction clutch
- S4 TII transmission
- Custom Drivshaft
- 4.44 ring gear
- Torsen Differential
- possibly lightened steel flywheel
- 10 and 6 PSI pulley set
- Racing beat Street port exhaust system with custom muffler

Welcome to the world of 14's...not 12's my friend. Go turbo if you want 12's.
A supercharger provises a lot more torque with a broad powerband based on my reading while the turbo can provide more horsepower, but peaky and at a higher rpm. It seems the s/c would be more streetable and provide the engine with a longer life span. The best analogy I can make (being an old fart), what sounds like more fun, a camaro with a 375hp 302 (yep, gm made a 302 in the lat 60's for the transam racing series for all you younger folk) or a camaro with a big block 396 pushing the same 375 hp. Both may run neck & neck at the strip, but you'd have to pound on the 302 and hit 8000+ to compete while the 396 could be shifted at 6500 and win. Not only that, but pop the hood and nothing touches the look of a big block. What would people think of the sight of a superchager on the side of a tinly little rotary with a big weber side draft on top. Think many could even figure what it is?

I have run both superchargers and turbochargers on a V6 Ford back to back allowing only for the tune difference. Both at 10 psi. Both intercooled. The sc made a ton more torque and ran to 248 rwhp @ 4300 rpm the turbo made 259 rwhp at 6250 rpm.
While the turbo made 11 more horsepower it was in a range that was unuseable for the vehicle setup.
The turbo setup went on a buddies car and BOTH cars ran 13.40s but his was lighter car with a better setup rear suspension.
It is all in the final use of the engine.
I agree with the above pro-SC statements with one exception. The front stationary bearing tends to wear a little faster than stock. This happens when the FC fan tends to cause the waterpump pulley to slip and the alt is therefore lifted higher (to overtension the belt) to compensate. The solution is to switch to an electric fan. The Black Magic dual fan unit from Summit is probably a good one. Of course if your clutch fan isn't giving you problems, keep it because it sucks in a good way.
Back to the topic. Yes, supercharging a rotary is great because it gives the rotary a boost where it actually needs it; at low RPM. I've very interested to see the new SC on the CodeBlue car.
