I spoke with Andy Mears in Lovett Texas. He's running a 13B full bridgeport and a 9" camden.

The biggest problem that i have found with my camden is actually in my motor, I am very hesitant to use a bridgeport. I have a big streetport and the overlap that i have is already causing me problems, now it might also be the fact that i am running a -10 pulley on a 7-inch but I have too much boost at low rpm. The overlap is actually increasing my exhaust backpressure. My next step is a monster exhaust port with a smaller intake port and back off the boost a little bit. You have to make absolutely certain that you have no exhaust restrictions or your numbers will suffer. Pose this question to Dave Atkins and he will verify this through his own R&D on the blowers

Dan has done little R&D. I have run a 6,7,8 and 10 pulley as I own the 7&8 and I have a buddy here with the 6&10. The 10 is totally useless, it builds an immediate 15+ lbs of boos but quickly falls off up top likley due to heat and cavitation. That #10 pulley heats up the charger like a blow torch and kills all efficiency. When that thing gets hot you lose everything! The #7 pulley is ideal, Andy had tried a few different combinations on Code Blues car and found the 7 to be the most effective. The smaller pulley increases immediate boost while losing efficiency at higher rpm and quickly building heat. The bigger #6 pulley brought less boost down low however I lost no boost at all up top and had a dramatic reduction in heat. Check out the following link, you will find it very informative. http://www.holley.com/data/TechService/Technical/Supercharger%20Tech%20Info.pdf#search='weiandblowe r I will be going half bridge on my secondaries and streetport on my primaries with a large exhaust port running the #7 pulley and a 850 double pumper.

And then Code Blue said screw it and put in a turbo 13b....supercharger was to much trouble, and not efficent.

Very true, with unlimited funds and the necessary skill a turbo will deliver much more power. The s/c has delivered as promissed, is very simple and very reliable and drives much like n/a only with more power. You have no need for a standalone with the s/c, and pulley and carb swaps are simple. A turbo with a good standalone and supporting mods will provide more power with the aid of good tuning skills. There is no debate, each has it's own application. For me, I have the s/c and will make the best of it. To advise another or start over again, I usually suggest a TII swap.

Lets not turn this into a s/c flaming thread, there are many of us with the s/c who like it and colaberate on getting the most out of it.

My biggest mistake was getting the 7" instead of the 9". Andy Mears reportedly runs 10's with his bridged 13b and 9" producing 20lbs boost in I believe a lightened Rx3 with a tubular chassis.

Yes i know...not trying to start anything....just fillling in the gaps.

Code Blue, not super charged anymore
Builder was Atkins
Tuner was atkins i believe?
Was the second motor with super charger?
Finally went to Turbo also built and tuned by atkins i think?
Hasnt had any trouble yet.

its been awhile sence i have talked to Code blue i should call her up.






i myself am looking to start a 12a S/c 1/2 Bp maybe for porting...any suggestions?

That's the problem with "I read" and "I think", people saying this usually don't know! There are a couple however who have had both the s/c and turbo and can speak from experience. Code Blue used to praise the s/c, this was a big basis for my decision. It promisses 35% and delivers! Most critics have never even driven a s/c rotary before, thus some hesitation for us to post becasue some idiot always has to chime in on a constructive thread with unwanted criticism.

No - that makes you the typical poster here who wants to be able to freely spout your opinion but limit anyone elses ability to disagree with it. That violates the basic principle of a forum board being a "free exchange of information". Post your questions nd information, then trust yourself and everyone else to use whatever brainpower they have to evaluate the presented information and decide which parts to have faith in. Quit whining anytime someone posts something that you don't like.

Atkins = bad customer service. Firsthand experience. Some of their products are undoubtedly fine, but in the cases where they are not their willingness to stand behind them are suspect. Having to tolerate "Mama Atkins" people skills to resolve issues or get any information was enough to drive me away, and keep me away.

Say something bad about Atkins and get banned from the forum, because the operator of this particular forum is in a money based, lawsuit fearing, censorship position. SO - you need to use your brain and take personal responsibility for the good or bad that may come from YOUR decisions if they are based on information that you get from OPINIONS posted here.

Whoa Whoa Whoa

Yea

I and for all y'all that are doing the Atkins Bashing there are many many more of us out here who have had great customer service from them and do deal directly with them and have been very very happy, also if you weren't at the track with Code blue and know the full story butt out. That thread was closed along time ago because of miss information and LIES. If you have factual information and can post dyno sheets with and 1/4 mile times then do so. Bottom line is this and code blue knows it. My S/c 13b 6-port running a camden s/c 5 inch with a holley 390 in a 74 Rx4 with a 4 speed ribcase 3.6 rear gears no LSD unit, street tires and more weight still ran faster.

You want to know why I am pissed, simple, this was a thread about people with superchargers that was talking about how they are tuning them and what engine combinations that they are using with them, it had nothing to do with CODE BLUE BEING PISSED AT ATKINS.

What I want to know is if CB had a problem with the S/C what was it and did they fix the problem or just bitch about..... I know that answer I was there you weren't.

This is not a thread of turbo owners bashing s/c owners, this is not a thread of customers bashing businesses take that crap to the good guy bad guy area and make sure you invite the person you are SLANDERING.

Now for the last item I see HP numbers, lets see the Torque numbers and oh BTW make sure you post the whole sheet so that we can compare the graphs at the different RPMs.

SGT Dave yea that is posted for those in the Northwest that know me.

I agree, this was a thread for s/c owners to compare successes and questions. Not an invitation to bash the s/c or atkins. My beef was to keep things positive and informational!
