Supercharged rotary for road course?

I do quiet a few open track days on my FC, about 1-2 times a month. I recenlty picked up a camden super charger for cheap, and I'm debating put it on in risk of blowing the charger at the track. So I'm wonder if anyone out here runs one, or knows someone who runs one and has had good success with it on a road course.
I only plan on running 5psi, and have the fuel to support it. I don't expect to make crazy power, just wanted a bit more power coming out of the corners, and in the straits.
But my main concern is just the charger seizing up on me on the track, and as this is my daily driver I don't want to trash anything.
The charger is 7" camden charger.

So is charger good for constant revs, 5-8k for 30-40 min sessions?

And I ask, please don't turn this into a turbo is better the SC debate.. Almost every thread I found on my search ended in this.

Just looking for people who have ran a simlar setup, or know of poeple who have ran a simlar setup with success of failure.

Thanks for your time.

Alright, I got the SC installed and running. Going to get my injectors and fuel pump this weekend so I can tune it.

I will update on my experience with the charger at buttonwillow. I will be there for both days of mazdafest, May 20-21st.

Your welcome to check out the car there.

Here is the thread in the 2nd gen section about my install.

Let me know if you guys have any suggestions.

Thanks.

I'd be a little concerned about the heat load. Superchargers are notorious for a hot intake charge. I'd really advise stepping down with the pulley, just to keep the rpms on the supercharger a little lower. I might also be tempted to shift a little early, just use the torque.

Yea, I'm only using a 6psi pully. Going to tune it this weekend and see where the powerband sits.

Also will be tunning alittle rich so that it can help cool off the hot compressed air.

Hey Alvaro,

You may want to consider water injection. I have seen a couple of setups that utilize a half inch plate between the supercharger and the intake to mount a water injection nozzle.


It is not a quick and easy solution but it will definetly help out in the long run.

I was thinking of water or methonal injection.. but I plan on selling the car after mazdafest and buy an FD.. So don't want to put to much more money into it. Just want to break even and call it a day.
