For those of you that do not know, SFPH was indeed the "Originator", "Inventor" and Manufacturer of the World's First ( DUB - Dial_Ur_Boost) Interchangeable/Modular Supercharger Pulley Unit for all Eaton Roots Style Superchargers on the planet. We first brought this product to the marketplace back in 1999 to the Pontiac Grand Prix GTP crowd, at the 1999 Grand Prix Gathering in Kansas City.

Since then, we have made Interchangeable Supercharger Pulley Units for all GM Vehicles equipped with the Eaton Model 90 Supercharger, plus the addition of the 99-04 Ford Lightning, 03-04 Harley Davidson, 03 - 04 Cobra vehicles, now for the GM Ion Redlines, Cobalt SS's.

Any Interchangeable/Modular Supercharger Pulley Unit you see on the market that does not have our TR#### part number on, is a copy of our product. Hope this helps, as read the "NOTICE" on all of our DUB Interchangeable Supercharger Pulley Unit pages and you will see this valuable information. Check it out here:

NOTICE: It has been brought to our attention, that one or more companies are copying our South Florida Pulley Headquarters' Dial_Ur_Boost - The World's First Modular Interchangeable Supercharger Pulley Unit Design. DO NOT be taken in by a company that is making a Modified Version of, or an look-a-like Imitation Copy of the ORIGINAL DUB that South Florida Pulley HQ Invented & Manufactured for these vehicles. You will probably see some Cheap Advertised Prices for these copies, but they will never be as close to the Original Quality or Workmanship as the already Proven & Tested on our Dial_Ur_Boost Supercharger Pulley Unit for the past 5 years it has been on the market.

Also remember our DUB Unit has a "Lifetime Warranty" to the Original Buyer, on the car it was originally installed on. How many companies warrant any product with a warranty like that!!!! Answer....NONE!!!!!!!

Thanks for reading about our latest information and passing it along to our consumers for an Informative Buyer's Beware posting of this latest news, that could cost you more in the long run for buying one of these Copies or Imitations!

Im not flaming, but just because someone comes out with another pulley system, doesnt neccesarily mean that they are worse. However, i will agree that some people will come designs. If the company does their research and makes their own kit, it doesnt neccesarily mean its poorer quality. It might be, but it might not.

For example, although you may be the first to put out a pulley system for the m90, ZZP and INTENSE have made their own pulley and, no offense, i would get one of theirs over a DUB system any day. Not saying yours sucks, just that i think theirs are better.

 

stuffy236, thank you for your opinion, as my posting of this information is to let others know where the Interchangable Supercharger Pulley Unit "Originated" and yes, there are several companies out here, that did in fact copy the DUB's HUB Assembly & Pulley Ring Design.

But to say the others are a better quality made, over the our Original Design, is not warranted here, as the DUB has been installed on several GM & Ford vehicles for the past 6 years, working Flawlessly!! Hope this helps.

 

This may sound silly but, I am really cinsidering a 3.25" pully . I remember going to car shows and seeing old hotrods with big ass sc's mounted on them and when stared, at idol, you could hearthe sc whining. Will using a smaller pulley give me this effect? Also my biggest concern as well is if I get a 3.25" pulley i know the computer do not need to be reset but is there any harm I could do with going with that size pulley??? Also, what about the belt, will there be any slack to the belt with going to a smaller pulley?

 

Good question on the belt. The SFPH website says you can do a 3.25 without an ECU/PCM recalibration. Any smaller and you need to change up the computer to get it to work ok.

 

For every 2 sizes smaller on these supercharger pulleys, you will have to go to a belt 1/2" shorter than factory. Considering SC Belts are Double Grooved belts, (meaning grooved on both sides) you might have to order the belt through a NAPA, Auto Zone parts store. Also it is a good idea with running a 3.25" pulley , that you regap the factory plugs to .035, verses the factory gap of .040. Hope this helps

 

Just Wandering About The Hp Gain I Know If The Sc Is Spinning More It Should Have Some Kind Of Gain. Another Question You May Not Know The Answer Or You May? Will The Cobalt Ss Run On Boush Platinium +4 Spark Plugs, I Had Them In My Z24 And They Were Great For That Added Spark.

 

generally, platinum plugs arent great for supercharger cars. even the most modded GTP guys are still running regular plugs, just a few degrees colder than stock.

 

The superchargers you are referring to whine mostly because of the toothed belt and pulleys, not the rotors or the gears. The gears do whine but not near as loud as the belt. The toothed belt is used because of slippage. An 8-71 supercharger takes a certain amount of power to drive and the toothed belt keeps the blower running with the crank, without it (on a powerful V8) the engine would overpower the belt and the crank would accelerate faster than the blower. This is especially true with blowers that are overdriven (run faster than the crank).
The whine you hear on the SS is mainly from the gears. If you could find a toothed belt and pulley system for the SS, it would really scream!!!
As far as power, you may not see more power but it would most certainly bring the HP and Torque curve down on the RPM scale. In other words, peak power would drop from say 6000 RPM to say 5000. Why, because all your doing is bringing the boost in sooner. Instead of say 12 PSI at 6K you may get it at 5K, but no more as the bypass valve will vent the excess pressure.
Anyone wish to add to this please do.

 

actually, you wouldnt drop the power band. You would just add more power down low. Since the BBV is limiting the amount of boost, you wont gain more up top, but you wont lose it either. However, you may gain a little if youre like some people and not getting 12.5 psi stock.

 

WHAT'S THE HP GAIN ON THE 3.25 PULLEY?

 

There is a company that makes a piggy back ECU and a 2.8 inch pulley kit that claims 24 hp addition.

 

i talked to them erlier they said 15-20 hp and tq gains

 

so it's going down now???? crap that's not alot for a pulley that size and a piggyback... no way i'm paying that much for maybe 20 hp... i'd rather dish out a stright $1k and get a real amount of hp when it's available

 

ma bad man thats hp an tq for 3.25 pulley

 

From what I heard every size smaller you go, you get ten ponies . I want to go to a 3.25" pully so I heard a gain of 20hp. PLus I have a CAI ( Stock intake pipe with K&N e-1009 filter popped right on the end no filter box) so I am hoping that with those two things done I can get an extra 28-30hp on top of the 217(dyno'd) stock number. Would love to get into the porting of the blower but need to find someone local,,,not easy.

 

for $139.00 for what they are asking for the DUB system is not bad for an extra 20hp. supposedly for every pound of boost added you figure is an extra 10hp. the 3.25" pulley adds 2lbs of boost

 

i got mine in today so hopefully this weekend it will b on

 

OK OK .........I want to buy a 3.25" pulley. .... What else do I have to buy so I will not hurt the car? Also is it "easy" to put a tighter belt on for the3.25" pulley or do I have to pay someone? It looks tight in there. Also is there any reason why I should not want to get a smaller pulley? engine damage whatever I'd like to know you guys rock sand I need more info before I buy.

 

alright guy my pulley is on and running good no belt change needed had to take pulley to local machine shop to have factory pulley removed u need to remove blower to do this once the adapter is on its all gravy from there so ill let u all know wut happens over tha next couple of days

 

Well to be fair, its tuff luck to you guys, people have been back-engineering the competition for years. When GM first came out with Displacment on Demand, you think it took long for Dodge to get one, see how it worked, then rename it and slap it on its own products?

You have every right to say you were there first, but without first hand experiance you can't say theres is any werse, especially if its a direct copy of yours.

 

Please everyone listen to me. The car will make more boost with a smaller pulley!! Psi-fi isn't bypassing anything on the BPV with there 16 psi kit.

ADD A SMALLER PULLEY AND YOU WILL MAKE MORE BOOST

someone sticky that please, I am unsure how this rumor got started or why it is believed so widespread.

 

ok I am locking this because it's so off topic.
