Camden Dyno Poll
#27
The biggest reason I dont say a thing on the Supercharger threads is I have been beaten and reneaten so many times that is makes the main guy {Me} making the kits not care and this goes for anyone else that makes new parts or kits for a 20 + year old car..
If you want info than you will have to call me on it....
as for dyno pulles I have had my 82 up to 175RWH or so and that was just tuned enough to surrive on the dyno.. Yes I could have done better with better tuning..

Airflow is my life
Its too bad you cant get a gilmer setup for it. Anyway Im still keeping up on this thread. Nice chatting with you Dan at SS this year. It was Sterling and I who were hitting you up about the camden.

yeah as if getting ahold of anyone at atkins is even a possibility.
Ive emailed them for pullies like 3 times
Ive called there and the voicemail is full...
How the hell does a guy get ahold of some pullies!

Well, I pm'ed Dan with the option of contributing to an extensive dyno pull consisting of testing a variety of factors (various pulleys, etc) so we'll see what they wanna do to demonstrate to all of you the full potential of the camden as I feel there is still much more to be had than where I am currently at.
#37
Ahhhh, news flash.......I blew up the motor with some distributor advance experimentation. Dyno pull will happen for certain though! I did get feedback from Dan Atkins though, he already has plenty of dyno results. Bottom line: turbo=more power, camden=simple, effective, torquey, honest 30+hp gain but that's the limit. For those who want to bash the camden and atkins for not furthering development you have to realize that they only sell 10-20 units/year. This is not a big part of their business, so to make improvements by developing a twisted 3 lobe rotor for instance would not even make break even against profit for several years. Soooo, it does what it promises and for those who have them we are grateful that Atkins continues to build and offer this product.

A camden only gives a 30% gain ?
Hardly seems worth it... I mean on a stock engine you get 20% out of a RB Exhaust...
Still, I've always wanted one of these... Maybe one of these days I'll get around to it. I'm still planning to do a crazy 12a N/A build up first.

Its not a fast as hell kind of unit, it is an all around fun driving.
I'll be honest I was alittle dissapointed by the hp #'s given for a supercharged 12a but driving it is so much fun and it feels so responsive at any rpm. Makes for a great driving car.

Exactly! The point I was making is the only alternative way to get that kind of all around driveability and responsiveness is to spend bigger bucks on a 3 rotor of some sort, either 12A based (17A) like that Hurley package with the three SU carbs and side ports, or a real 20B with EFI. Boost is optional of course as the three rotors fill in the gaps in the lower RPM that a 2 rotor normally has, whether boosted or not. They're also even more responsive without a turbo corking up the exhaust.
Anyway if you want the power of a 3 rotor without the associated costs and fitment issues, a supercharger is the only way to go. If however you're looking for bragging rights for high HP numbers and less driveabilty down low, then by all means go turbo. I'm not saying they're good or bad, I'm simply saying an SC is more pleasant to drive than an NA or turbo 2 rotor because the extra power is there as soon as you flex your ankle. No waiting for the RPMs to climb before you start feeling something.

I'm curious how adaptable it would be to a GSL-SE setup, too. For 8 psi, you're looking at 1.5 atmospheres, minus the heating losses. Would you just bump up the pressure or oversize the injectors and stick with the stock ECU, or would you need S4 manifolds with secondary injectors that fire in parallel with the stockers, and you only ground the secondaries when you're on the boost?
Is there a bypass circuit in the supercharger like I'm used to seeing on Kenne Bell?

Nope, as mentioned earlier atkins does not sell enough to invest in the R&D to bring it up to date

It is possible to see more than 30% increases. My buddies 12a (now John's) ran 150 hp on a dynojet. My original 13b ran 158 rwhp on a mustang dyno. Codeblue's 13b ran 210hp on a mustang dyno. I hope to see the 200 mark now that I have things dialed in better, particularly the exhaust. My first dyno pull included an exhaust with 2 presilencers and a muffler. So in each of these cases, the camden actually gave in increase of about 50-80% over stock, or 35-50% over a streetported n/a equivalent with exhaust upgrades......a 13b fb will walk away from a stock TII in 60 feet and the TII will catch it after the 1/8 mile. Not bad for a bolt on.

I went for a ride in the supercharged 510 today and it really gets up and moves. -10 pulley, 5" SC, aluminum flywheel, 2200 pound car (2500 with us in it) and a basic street port on a set of Y plates and '74 rotor housings with '86-'88 NA rotors (9.4CR). We estimate it has 190-195 HP which is 30% over an estimated 150HP in NA mode. I think I got the math correct. It accelerates like an FD with healthy stock twins which dynoed 205HP at the wheels recently.
I'd say 190ish is probably fairly accurate, but then again he still needs to dyno the 510 so we'll see. The actual HP numbers will probably be less, but it certainly feels like a lot. John Smack knows what I'm talking about.
