Ported and Polished Six Port 13B with Seven Inch Supercharger
Horsepower: 276 HP

Enough ponies to get you into the low 13s at least. Probably even faster.

If you are making power lower in the Rev range, there shouldnt be any reason to rev to 8k.
What is it with you kids and 8000 RPMs?

thanks jarrett, i am looking into getting a n/a and supercharging it i just wanted to have an idea if the 1/4 times were decent. i still have a lot of research to do about it because i still dont know what port will go best with it or what sc i would want to buy, i do know i dont want to buy one that will only boost a low number, i want at least 10 pounds when im done

Sorry I cant provide the 1/4 mile times, but at 275 hps, that car should be a rocket....
For what its worth, if you are going to push 10 PSI, you are probably going to need a 4-port. They have lower compression. But thats just going on what I know. No factual basis whatsoever...

You could build a 6-port to handle the high hp and torque, but J-Rat is correct in the statement that a 4-port with lower compression will handle the high boost better for a longer period of time.
High boost w/ high compression will cause things to constantly blow apart over and over unless you have it built right the first time. 3mm 1 piece Apex seals, ported, etc. etc.
Look into an Atkins Rotary rebuild. They offer all sorts of high-performance turbo engines, which will take to a supercharger very well. At the very least, their website will give you some ideas on what you are going to want to use.
Good luck and I hope your wallet is deep

Worst thing I ever saw was a porsche speedster replica on a vw chassis...rotary engine in back with a supercharger...thing was slower than modified vws off the street. UGH. You would think that the lightweight kit car with that combo would do pretty good.

Well, its not that, Im not one of those people that wants to rev to 10K just because. On a v-8 or similar where power peaks at 6500rpm, a S/C is fine. But on a rotary or other high-revving engine, the power continues to build until 7-8k. Why would I want to limit my potential with a S/C that runs out of steam at 6k? I personally dont care that much about rpm, but I want to be able to use all the available power and rpms that I have available.

If full power is being developed at 6 K, I will take it. I would much rather make full hps lower in the band, then have to rev the livin **** out of my Motor.
I cant comment on the performance of the Camden charger. I dont have any dyno charts. And the site doesnt specify where the max power was made. But since the guy that owns Atkins, also owns Camden, I would be willing to bet that the charger is designed to handle the higher revs of the rotary.
FWIW, I would rather go turbo...

I saw a custom job today at a local meet - 87 FC (NA model) w/ a bridge port and supercharger pushing out 20 PSI (absolutely crazy car). Fully adjustable suspension etc...looses traction in fourth when floored at regular highway speeds!! The car needs paint pretty badly but it's scary fast!!

A super charger can be modified to start producing boost whenever you want to...... It all has to do with gearing. Just put one HUGE pulley on the thing at it wont spin very fast until you hit 6k rpms if you dont want it to.
