Hi guy's! We here at South Florida Pulley HQ want to introduce ourselves to you. We are the very first company to come out with smaller Supercharger Pulleys for all of the Eaton Superchargers in this country and abroad. We have been successfully making supercharger pulleys for the past 7 years , as well as running our Online Store.

We are also the very First Supercharger Pulley company to not only "Invent, but Manufacture" the World's First Interchangeable/Modular Supercharger Pulley Unit 6 years ago for all GM/Ford applications. It is Called the Dial_Ur_Boost Interchangeable Supercharger Pulley Unit!

http://www.southfloridapulleyhq.com/images/products/dub_assembled.jpg

The new Chevy Cobalt SS as well as the new Saturn Ion Redline can use our DUB (Dial_Ur_Boost) Interchangeable Supercharger Pulley Units, to give you the added boost and horsepower, the average performance enthusiast is looking for in the increased "Boost" area.

Of course when running higher levels of boost, certain things need to be taken into careful consideration and that is running a good Octane Fuel, such as Sunoco/Amoco/Mobil 93 octane.

We recommend starting off with our DUB 3.25" Pulley Unit, which will net you an additional 2 lbs. boost over the factory and regapping your Sparkplugs down .005.

Also, any pulley size smaller than our 3.25" , we highly suggest changing to One range colder sparkplug and regapping those new sparkplugs down at least .005 , to help lower the cylinder temperatures, associated with running higher boost levels over 2 more lbs. at wide open throttle.

Also with running a pulley smaller than a 3.25", we recommend PCM reprogramming, as well as using One range colder sparkplugs. Hope this helps, as we are in the midst of updating our website for the Saturn Ion Redline/Chevy Cobalt SS sections for our DUB Pulley Units.

You can check out these DUB Pulley Units at this link provided.

Not at all trying to be a dick, but upon what are you basing your claims that a 3.25" pulley will generate 2lbs more boost?

I had been under the impression that the stock pulley was 84mm/3.3" (not 3.8" like the L67/L32). A 3.25" pulley is less than 2% smaller - doesn't seem like this would make much of a difference at all, let alone 2lbs.

Or does our motor use a 3.4+" stock pulley?

Or does our motor use a 3.4+" stock pulley?

Dan, your supercharger is using a stock 3.5" pulley, as by going to our 3.25" , you will be producing 2 lbs. more boost, which is fully dependant upon the Altitude Factors in your area, it could be 1/2 lb. difference either way + or -.Hope this helps.

Ah, so it's 3.5" stock? Interesting .. thx.

Not to bad of a price concidering you will get 2 lbs of boost more. Thanks for the info.

If I bought one of these pulleys smaller than 3.25 what kind of computer tunning would be involved? Also what kind of boost/ HP gains could be expected with going smaller. What would be the max PSI the motor could handle before major mods had to be done? Thanks in advance. :) Just on a curious sidenote-----would this help give the car more "WHINE" when in the throttle, because now you can barely hear it.

Ronnie, with any Supercharged Engine, when producing more than factory recommended boost levels, you must first check your Air/Fuel Ratio Numbers, to see if they are within specifications (meaning between 11.8 to 12.0) for Optimal Performance at wide open throttle.

Several things needed to be addressed with increasing these boost levels, such as replacing the Factory Intake System with a more efficient Cold Air system, as the supercharger is demanding more air flow to maximize the power gains you are looking for.

Also, it is always best to remove the sparkplugs and regap them and close the gap by minimum of .005 to help reduce cylinder tempatures for Optimal Performance, when increasing the boost 2 lbs. over stock 3.5" pulley, with the addition of our 3.25" DUB Pulley Unit.

Any supercharger pulley producing more than 2 lbs. boost will need a sparkplug change, to One range Colder and gap them .005 close gap , over factory, to optimal performance , plus the need to Reprogram the PCM for optimal performance (meaning Air/Fuel Ratio-Timing etc.

Also , with running higher boost levels over stock configuration, you should pay particular attention to the restrictive OEM Cat Back Exhaust system on your car and go with a less restrictive exhaust, as the supercharger is making more power and needs a more efficient exhaust for these back pressures to escape through.

Hope this helps, as always remember this! The more boost the engine is producing , the more efficent Air Intake System is needed, plus an Upgraded Cat Back Exhaust for this conbination to work properly.

Yeah but what about the lil "vaccum tube thing" that the RL owners say they can unplug and get 2 more psi. If you dont unplug that even with a new pulley wouldnt it still limit you to stock psi??!?!

we are still awaiting that answer

The particular part about reprogram the PCM is what i am interested about. I.E. What if I bought the smallest pulley you had for my car. What would have to be done to the PCM program (something like a Hypertech, or does it need to be professionally done on a dyno). Will my cars stock componets (pistons, rods, blower, etc..) be able to handle this much more PSI. You forgot to answer my question about whether or not one of your pulleys will make my blower "WHINE" more. I am new to aspirated engines, all i have delt with are LT1 and LS1. I have a 2001 Camaro SS (417rwhp 404rwtq) Me and my fiance just bought a Cobalt SS and we both have the mod bug!!! Thanks for all of your help and being patient with me! :confused:

Thanks for all of your help and being patient with me! :confused:Ronnie, regardless to how small a pulley you use, you will experience more whine coming out of the supercharger, especially if you have a good cold air system installed on the vehicle.

The PCM Tuning is very important on any vehicle, regardless to what make and model it is, as when you make more than 2 to 3 lbs. over the stock configuration, you will have to have a professional tune, to give you Optimal fuel management and timing properties. Hope this helps, as there is no Magic in installing any supercharger puley, without first finding out what your Air/Fuel Ratio's are and having a proper tune.

Most Handheld Programmers do not have the capabilites of adjusting fuel or timing, when you are running more than 2 to 3 lbs. boost. That being said then, we highly recommend a good safe dyno tune, when running over 3 lbs. boost added to the equation.

But what about the boost bypass valve (thingy). It limits the boost to 12lbs regardless of the size of the pulley. Going to a smaller pulley will only get you to the 12lbs sooner, not give you any more. Unless you are offering some sort of computer upgrade, your smaller pulley WILL NOT give us more boost. It will merely get us to max boost sooner. And plugging the bypass hose IS NOT the answer, as that is merely the easy way out and could possibly damage the engine. I would like to hear your solution to this.

XeroState, I certainly do not know what you mean in stating your car will not produce more boost with a smaller supercharger pulley, as that statment is not true. We have at present 5 Ion's in Texas running these pulleys and certainly producing 14 lbs. boost at wide open throttle.

It would be good for you to tell us where you got this information? Hope this helps, as a good Tuner can eliminate any higher boost problems that could occur on any supercharged engine! It would be interesting for those who have tried to build more boost, with installing a smaller supercharger pulley, to come forth and explain to us that they have tried it and failed!!

Yeah but people w/ STOCK pulleys on Redline's are pluggin that bypass valve and pushin 14PSI WITHOUT a pulley change! Check the Redlineforums! Id rather pay oh ummm FREE!
Thats what we were askin about.

Exactly. Now this isn't the safest way to gain boost, but it works. And for you SFPH, if you really knew our engines, you would know about the boost bypass valve. Now how does your pulley give us more boost, when the valve DOESN'T allow for any more than 12 as it bleeds out any extra (as our STOCK SC produces 14.5psi above 4500rpms...redline owners have seen this). Please, I'd like to hear your solution...and it better not be "plug it" as that gives us the 2 lbs that your smaller pulley gives us.

Word! As of yet, Im unimpressed, interested, but unimpressed none the less.

As am I. This seems to be a sort of "quick fix" that doesn't solve anything we can't do for free. And the fact that here on this forum, and on the redline forum, they ignore the question of the boost bypass valve makes me wonder if it works at all. They clam they have 4 redlines in texas with them, but who is to say that they haven't plugged the bypass and gained nothing from the pulley. Guess only time will tell.

Hummm..... something i a little fishy if they do not know anything about bypass valve. I need to know more now.... i mean we all need to know are you really sure on this?

Here (http://www.redlineforums.com/forums/showthread.php?t=1115) is the link to one of our (redline owners...yes I am a redline owner) discussion about it. There are many there, I am really to lazy to find them all, just search for "Boost Bypass".

Thanks for the link. And here is some said that was very interesting to me.
[UncleSmitty]
I did dyno the car with and without the bypass mod. Without, I got 216.8HP & 211.4HP. Immediately after the 2nd run I did the mod and got 212.3HP.

True, while others were gaining 2.5lbs, so I guess its sort of a hit or miss situation. Or their boost gauges are off by a bit and dynos off too.

Yeah and also he said IMMEDIATELY. Dont folks normally let them cool for a while?! Probably had the engine runnin hot as shit on that third pull!

No kidding. Blowing hot air into the engine will kill power..considering dyno's don't have blowing air on them (other than fans, which don't work like real air). I'd still like to hear from SFPH tho about this, as they seem to be ignoring the question on the redline forum, which is why I posted it here too.

Yeah and also he said IMMEDIATELY. Dont folks normally let them cool for a while?! Probably had the engine runnin hot as shit on that third pull!

Yeah that is true. Well he should just try it again but he should alow cool down time.

I just hope this isnt somebody's idea of a "get rich quick" deal. I'll probably be passin this one up. Not enough REAL info.

<===600!

Yeah me to.
Post wore!!!! LOL J/K :p :D

If I were to upgrade my SC, I'd go with Psi-Fi's "piggyback" system. It re-tunes the computer, has new injectors so more fuels goes into the system so it doesn't run EXTREMELY lean with the extra boost, and a new pulley. And it has been testing for about 2 months now I believe. Tonight they are having a public showing of it and demonstration (I live like 5 hrs away by plane tho :( ). I would trust that set-up much more than a simple pulley swap as it seems to me they have done no research into the engine and the problems that may occur by using a smaller pulley (if they can get anything to happen in the first place).

I didnt know Psi Fi had anything released yet?! Thats awesome! What about their twin charging system? Is it near completion? Also, I wonder if anyone will come out with an aftermarket S/C thats more efficient than the current stock ones??

I believe someone on the RedlineForums.com website posted that they gained 3mph in the 1/4 with no other changes besides the pulley. 3mph is nothing to sneeze at, thats a decent gain for this price (3mph equates to roughly 30hp at the wheels)

I tend to believe track results over everything else. Granted, one test is not the end all, be all of tests... but I think it shows that the product deserves some more testing from other individuals before going overboard condeming it.

Also, most Lightning guys get HUGE gains from simply a pulley change. I dont think the S/C on the Cobalt/Redline is huffing past its efficiency post at stock boost levels, so this pulley _seems_ to be a decent modification.

It's not released, its merely on public demonstration. They say soon tho (I believe).

What is Psi-Fi's website? I'll probably be goin with them and definitely with Modern Performance!

I have no idea what their website is. www.psi-fi.com maybe? I just read the www.redlineforums.com forums. Granted the info may be a little out to lunch at times, but occasionally you get some decent info.

Here's the website for PSI-FI.

http://www.psifimotorsports.com/

Preciate it!

Hmmm...still no response from SFPH on this (after a full bussiness day).

Oh well... MODERN PERFORMANCE IS HERE!!!!!! WOOHOO!!!!
And they WILL achieve some REAL horsepower!!!

Agreed. Lets hope they will share a little more info with their possible customers.

XeroState, normally on any Forced Air Induction engine , you must first take the necessary precautionary measures against excess heat intrusion into the engine , by making a few changes. One of them is changing the factory restrictive air intake system, to a less restrictive system, to let the added air flow into the engine.

Secondly, you should either (dependant upon size of smaller SC pulley) change the stock sparkplugs over to one range colder and close the gap, to lower cylinder temperatures. Thridly, is is like I mentioned in the Redline Forum, you must check your Air/Fuel Ratio numbers to make sure they are well inline of not being pon the Lean side ( 11.5 to 12.0 )

If after making these changes, then no increase in boost pressure is present, then a Boost Bypass is needed to allow the boost to increase (but at a safe level). Anything over a 2 lb. increase in boost, should have a Safe Computer Tune, to make sure the vehicle is not leaning out, that could cause, not only excessive knock retard, but also severe detonation and grenading of the engine.

However, a couple of people out in Texas have already done these modifications to attain 2 to 3 more lbs. of boost and are not having any problems so far. Also, we do not have any Dyno Results to report , but there are a couple of companies who have already purchased our pulleys that are having Dyno Tune Sessions in the next couple of weeks.

As soon as these results are in, we will post them accordingly. Hope this helps, as we are certainly not selling "Snake Oil" to the Supercharged Engine owners, just to make a "Quick Buck". Instead, we are offering a quick solution to making the needed horsepower levels, each Enthusiast desires to have.

For the past 7 years SFPH has been coming out with newer products for all Foreign & Domestic Supercharged Engine Owners and we have not failed in our quest, for them to achieve the horsepower produced by our smaller supercharger pulleys, with the proper tuning etc. to make this happen.

You might be limited in running higher levels of boost at this time with the ECU limited it, but shortly there will be several companies offering a solution, as to how to overcome these barriers and give everyone the performance they want.

$140 is cheap for maybe 10%+ more horsepower! Someone should try this out!!
Thats cheaper then most air intakes!

If this is true (which we all assume is), then please tell me how you are gaining the extra boost in the cars in Texas? I am not saying that your pulley will not produce more boost, I am just questioning whether this boost will arrive in the engine or not. If they have merely plugged the boost bypass, please just tell us this.

You seem to be dancing around the question (I am not trying to be an ass, but merely voicing my opinion) of how you can claim this-

WITHOUT a dyno sheet or tuning the ECU to allow more boost. If these "couple of people" are seeing the gain in boost, maybe their boost gauge is reading it before it reaches the bypass which bleeds off excess amounts of boost. Please do not claim that your pulley will give us extra boost without proof, merely state that you have a smaller pulley which MAY or may not give boost without other modifications and they are currently testing this pulley and will have a dyno sheet soon. Customer relations (not that yours is bad, just your saying the wrong things) is very important, especially when most of us can't talk to you guys face to face.

XeroState, let me state this to you today and maybe like the rest of the 2.0 liter SC Engine owners. We do offer different supercharger pulley sizes to meet any Enthusiast performance need. This being fully dependant upon correct tuning etc. At best, we will post the results of the smaller supercharger pulley owners as soon as we have received them and then post the results, plus the modifications performed to attain the boost levels they will report back to us on.

At this time, we do not have these results, but will have them very soon. Again, I will state we do have different sized supercharger pulley units, for those people who are testing the smaller pulleys and to hopefully make a difference in performance, as well as their quest to attain maximum horsepower at "Safe Boost Levels", without these engines "Grenading" and having the proper Tuning Modifications performed on them. Hope this helps, as we are patiently awaiting these results and will post them accordingly.

87camaroPA , information we recieve on dyno results etc. will be made available to all of our customers. Hope this helps.


Yes it helps but i will need some long term test results to really get me hooked but i will be watching for them along with the dyno results. Thanks.

I cant believe you guys are questioning one of the top companies in aftermarket Eaton pullies. Way to be :rolleyes:
Thanks SFPH for serving us GTP guys so well. Maybe some of these guys will wake up and accept a good aftermarket product into their arena in a time when they are lacking in that department.
And on another note, do these cars even have a way to alter fuel delivery and ignition timing that the average consumer can easily use?

MY GTP 8 U, thanks for your honest opinion on posting to this forum. I guess these guy's do not really know who I am, muchless what I am all about. I have 17 years of Forced Air Induction Experience under my belt, plus have owned Turbo Regal Grand Nationals running into the 11's .

I was also the very first Supercharger Pulley Company on the Planet to Not only "Invent", but to also Manufacture the World's First Interchangeable / Modular Supercharger Pulley Unit , plus I am the Only Person responsible for all of the Smaller Supercharger Pulley for all Eaton Model 45, 62 , 90 112 Superchargers in this country. If any question this, call Jerry Magnusen / Owner of Magnusen Products, Inc.

My products are and have been so good, allot of companies have Stolen my Designs and made a Imitation or Look-alike Copy of my products and of course , sell them at "Cheap Prices" You can all buy the Best, the First Time Around, or spend your money with a company that Specializes in selling Keyfobs and Floormats, but our company Specializes only in Strictly Performance.

For those who do not know who SEMA is, I have been an active member of the SEMA Organization for the past 6 years out of 7 being in business. Please feel free to browse the following links on my Newly Innovated Products, that SEMA has approved and have uploaded onto their website for me. Hope this helps, as currently we have 4 new Supercharger Pulley Products that are going to be uploaded onto SEMA's website over the next couple of months.
