Any fellow camden owners using an exhaust heat shield over thier header and seen results. I decreased boost and gained power due to excess heat from the smaller pulley generating too much boost. I am also thinking of a fan driven transmission oil cooler mounted prior to the oil entering the s/c for some cooling. http://www.bulkpart.com/Merchant2/me...ode=derale-fan
Any suggestions or experience?

 

I wish I could help you.

 

why would you even post... this is one of the most useless posts i've ever seen! dont even post if you dont have anything positive to contribute



on a related note.... sounds like a good idea to me... but you may need to do alot of fabing

 

How big was the pulley you were using and how big is the pulley you're using now? I'm in the process of building up a 13B with a 5" Camden on it, and I've been worried that the small pulley on the supercharger would cause excessive boost and result in detonation.

Thanks,
Rich

 

I will admit I have nother to offer here but to slap rx7male in the face because he had nother to offer either. Mr 149 posts slapping someone who know more then he does, grow up kid.

 

it lets the poster know that someone cares enough to say something. No worse feeling like 200 views and not one comment.

it is also my way of saying I would like an SC car but dont have one.

and do you see the irony in what you said?????



Thanks for the Assist.

 

im wondering if you could use methanol injection to cool the intake charge, that would fight detonation and would make more power too

 

First off, if you run the small pulley you create too much heat, some cavitation and a loss of boost. I run a #7 pulley on the most current 7" camden and get 9 lbs boost right away and climbs to 11 at over 700 rpm with power building. With a #8 (smaller pulley) I quickly get 13lbs boost but seem to plateau for power at 6500rpm while the bigger pulley keeps gaining. I tried the #10 pulley (tiny little sob) and lost both boost and power however it sounded pretty cool. I paln on trying my buddy's #6 pulley as well. If you can cool the thing down, you'll gain power with more boost, but you gotta cool it first. This winter a friend of mine is gonna fabricate water/methanol injection into the factor spacer using a NOS spraybar and NOS jets so it can be fine tuned. His estimate here is approx 30hp, maybe more if we increase boost. An oil cooler is an easy install. Gonna do a custom header heat shield this week. I did a test with an "air bake" cookie sheet over a pot of boiling water. Shocking how little heat came thru. A little bending, drill a couple holes and I'll be set for $20 bucks.

 

Thanks for the info. Can you give me an idea what size the various pulleys are in inches diameter? I'm assuming the one I have is about as small as you can get (see the picture I attached previously).

Thanks,
Rich

 

this might be able to be applied to the camden. the route i was going to take was to use a ford svt supercharger because it has an intercooler(air to water)built into the base of it. basically its just a heater core.run a closed dedicated system with another intercooler in front of the radiator,small electric waterpump,and maybe even throw in an ice can for track days or runing extreme boost.

 

I am far from being SC savy, so my questions are this, what kind of intake charge temps are you seeing with the various sized pulleys?

Could you fabricate a intercooler core to cool of the incoming charge? or maybe sweat (braze?)some brass/copper tubing around the intake runners, and run water through them to keep the runners a little cooler (similer to an air to water intercooler unit but just run the cooling tubes around the intake runners)

just some thoughts.

kenn

I have been thinking about a camden unit myself, but with a turbo II throttle body, and injectors instead....

 

get water/methanol injection to reduce your intake temps. bam. you have to tune for this tho, cant run it on top of your current tune.

 

I also have a heat shield. I also heat wrapped my header, which seemed to cool things down more than the shield. It's fairly cheap stuff and can be bought through "jegs". Mid winter or so, the following is in the works for us people with Superchargers. http://www.theblowershop.com/ look under parts-innercoolers. They make innercoolers for piston superchargers, but are too big for us rotary peoples. Someone is in the process now of making one of the following innercoolers for the Superchargers to fit our cars.

I was also going to try water injection http://www.coolingmist.com/categorie...on=set&res=800 this fall.

Gary brooks that has done my setup mentioned to me about some fans to install in the engine bay that are extreamly powerful, I believe he said the cost was like $20ea. I will let you guys know as soon as I find out what he is talking about.

 

that intercooler almost seems pointless... wouldn't it heat soak? that seems worse off than the stock TMIC on TII's if you get the water/methanol injection mix setup going, youwill be FIIINE!!! egt's will drop dramatically! you just have to make sure you tune to it. well worth it and better off than paying 2000.00 for that interheatersoaker

 

Yep, going to try the water/methanol injection next and will see what it does. Right now my car seems to be keeping cool after the Microtech was tuned. I live in weather thats been over 90 degrees outside, and seems to be doing alright, but one can't have enough cooling.

Im also up for suggestions from everyone.

 

Nitrous will cool it down.

 

NOW you're talking!

 

64mg, you are running a #10 pulley

 

Thanks for the info! I'm assuming I should get a larger pulley. I'm not looking for *****-to-the-wall power...I just want a nice kick in the butt without having to worry about intercooling or anything. If that all goes well, then I might try something a little more powerful. But for now I'm only looking for about 6 pounds of boost. Which pulley would you recommend? I have the 5" blower.

Thanks,
Rich

 

I had heard you couldn't use that header wrap stuff cause of the higher exhaust temps of a rotary, but obviously you are using it. My header is full stainless, so it will probably take it. I may pick some of it. Sorry my post uses a random bit of info from this thread.

 

not true, heat wrap eeevverrryyyything

CODEBLUE: be ready to completely re-tune your car.. running a 50/50 water meth mix will not only cool down your intake temps greatly but will be like adding fuel. so you will notice egt's drop a **** load and your air fuels will dip way down. lean things out a bit to compensate and you should be back where you are now, but even more power and reliability. hell, you could even start getting crazy with it.... oh i dunno... add more timing? more boost? yayyy for injection!

 

64mg, use a #7 pulley!

 

Thanks! I'll get one ordered right away!

Rich

 

Yes heat wrap your header. Be prepared to freak out when theres smoke everywhere from the fibers burning to mold to your header. It only lasts about 20 minutes or so. Its a cheap mod and you will notice right off with your temps. Ive heard that eventually over time if you heat wrap your header that it will wear out, but who cares over time if it cools the thing down.

Yep I figure to re-tune it after doing another all mods. Car is actually "knock on wood" running very well so far. Here's another website that was sent to me by a former Camden employee. Rich these are those fans I was telling you about. I was considering maybe getting a couple to try out. Not the prettest mod but I hear they work good.

Let me know what you guys think

 

[COLOR=Blue]I can't believe it ! A place with some fellow Camden supercharger nuts.

If ever in Las Vegas e mail me and lets hook up. Its a fun town.


There's pictures of my car at www.camdensuperchargers.com

Go to the gallery section and click on the grey FC with chrome front fenders and polished hood. Theres more pictures posted there.

I run the 7" camden supercharger (#7- 10psi)
I've had good results so far with no heat related bugs. The big hood scoop is right over the air filters. I started out using 91 octane and had no detenation. Andy at Atkins suggested that 100 octane (available here at various local stations $4.50 gal) would gain me more power. It seems like it does have more power both on the low end and top end. It seems to rev faster. Our elevation here is 2100 feet and this summer is hot!! Up to 120 deg. F I haven't had any heat related problems this whole summer.

My ignition timing is on the aggresive side since I'm using the factory direct fire ignition. But have had no Detenation problems. I'm using high compression N/A rotors with TII turbo housings.

I'll have dyno results the friday before Seven Stock from Nick of Rotary Reliability & Racing. My car will be at their booth.
Running solid 13's in 1/4. Hopefully a little better after the dyno session.


I love this set up: lots of fun. I launch at 7000rpm and its a blast!

I'm so stoked about finding other camden people.
It was challenging to get this set up dialed in. No one out there til now.

Thanks
