Pulleys from srmotorsports.com

well this is a hard one because i get just as many good responses as i do negative.....i guess i will never know until i try huh?

Well pulleys dont have any bad effects on a turbo car. Supercharger is totally different. I wouldn't get them as I don't see them needed you will most likely have more power than you can use without them, if you get the set-up you want.

The balance shafts have nothing to do with either a SC or turbo, nor does it have any ill effects on the engine.
As stated by those that have it done it is more of a driveablitly mod than a Hp/tq mod.

So is there any bad things from running them...NO
Will it be worth it nope...IMO
 
in regards to the pulley/BS combo, they don't recommend them together, period. nothing to do with FI. Focus Central says the added vibration from lack of the BS would potentially bad for the udp on the car. but as i've said before, the pulley guys don't like the BS theory, and the BS guys aren't liking the pulley method...so just pick one if you wish.

But as he said, even if the pulley on a turbo duratec add (frees up as it may) 10hp or so, you won't be able to fully take advantage of it yet anyhow. though, for 129, it's an easy 10hp if it works out well. cause you know no matter what everyone would always like more HP!
 
Well i just placed my order through the company....so once i get them installed i will keep everyone posted on how they are doing and the overall price w/ install. if i can i will get it dynoed before and after but first i gotta find someone in my area.

Sounds as if they don't understand the BS. The Balance shafts have nothing to do with internal engine vibration, so I just can't see their reasoning having any truth to it.
That is like saying stiffer engine mounts and a UDP would not go together.
And there are duratecs running the BSD, UDP and stiffer engine mounts and there is still no facts/proof that it is bad.
Just alot of opinions.

But as I said I would not run a UDP on a turbo car for the fact that it is just money wasted. IMO
With all of the upgrades you state you are going to get you could easily turn up the boost a run 400whp, will you see a difference of the said 10whp from the UDP nope. But your pocket will.
 
only reason i'm doing it is to make sure it fits. there aren't many people that are willing to test stuff on their cars...i don't mind. i asked around and found 1 person that was a maybe if they could see someone else do it first...but i don't have that.

all i do is talk to companies about making stuff for the 6 (and sometimes the 3) and try to get them someone to test fit to make sure all is good. sometimes they are out of reach so i offer to be the test if they send a piece...that's all.

so far walters the only one if seen with both BS and UDP, but as i said, he now says it's a bad idea? don't know why, but as of 2 months ago thats where he stood on it. the people who make the pulley say not to as well, so i would take caution going against what the maker of the products says.

I have heard why he states he doesn't like the UDP, but it has nothing to do with it not working with the BSD. It has alot to do with the installation of the udp.
And the are many with the BSD and UDP.
There is just no rational reason for it not working with the BSD.

I understand what you are doing, but the last thing we need is rumors and opinions being spread around as fact!

I have talked to Walter many times and it is sad that he is not looking to work with the Mazda's any more. I do know he has his plate full with just the Focus stuff.
 
I have yet to find 1 person other than Walter with the combo on the duratec? though the only focus forum i follow is focaljet, so maybe they are on other forums?

As far as spreading "rumors", all i have said is what the companies tell me? i haven't said, "it'll break" "don't do it or you'll blow your engine", hell i haven't even said "don't do it". All i have said is what Walter from Marcy Motorsports, Ricardo from F2 Focus, and Dave from Focus Central have told me. these are the tuners of the engine so far, so i'm trusting their word. maybe i/they are wrong, but i'm supplying the info i'm givin.

Here's what i got from Walter on 7/2

"I'm replacing a 2.3 in a Focus froma botched UDP install late this month. The UDP can NOT be used in conjunction with a BS Delete, the crank pulley is guaranteed to fail when they are combined. I have 3 broken pulleys as proof. Bad mod, stay away.

A better design in the future may prove me wrong, but until then, you are warned.

..I'm not a "Mazda" guy. I have no first hand experience with the Mazda 6. From pictures, I know they will NOT fit the 3. Use it at your own risk. The BS Del. will not harm the engine. The pulley eventually will, you just never know when. "

So how is this, thinking they are ok together?

Here's Dave's thoughts

"I also would not suggest doing the balance shaft removal in conjunction with the pullies. The vibrations will increase and could cause the bolts on the crank pulley to work loose causing serious problems. There are no HP gains from the balance shaft removal. If anything it has a negative effect due to the greatly increased vibrations. If you want an example, imagine your Mazda6 or 3 running like a Zetec equipped Focus. Yuck!!!"

Ricardo is a bit more optimistic, talking about having his own pulley out in the near future.

take it for what it is, i'm stating what i hear, not spreading rumors

thanks for all the info guys...like i said....I will see how they come out and i will keep everyone posted on any HP gains/ problems etc... that i experience.


(uhm) BTW what is a Bal Shaft Del??????? sorry if i sound (braindead i just don't know

It is all speculation, with no merit. I find it funny how Marcy claims there are not added vibrations to the engine from the BSD, yet from what you post Focus Central claims there is.
Also funny how Walter got a 3whp and 3wtq gain from the BSD.

And yes all of the failures were from bad installs and a UDP coming loose. But was the UDP coming loose due to the BSD???? How could one state this, if anything I would say that was a bad install too.

And I had a Zetec Focus and automatic one at that with UDP and stiffer mounts and it was not that bad and the BSD on the Mazda3 is no where near that. You can't even tell it was done as far as vibration.

Ricardo being optimistic is one way of putting it, I would say he is a good tuner that likes to go against the grain....and I say that in a good way.

So once agian, I have nothing against you at all.
But it just sounds as if they are feeding you a bunch of bull. As that is definately not what they are stating on Focaljet or the other forums.

Everyone is against the UDP because of the detail it takes to install it.

And you can see by Marcy's choice to pull on the Turbo kits that he does not favor mods that bring you close to destroying an engine wherethere it be bad install or mis-use.

As I have said I have talked to Walter many times when I was trying to get him to make stuff for the Mazda3 and he has his own views on certain things.
Just ask him about removing the cats!

Anyway enjoy that boost and that BOV is making me very very anxious...thanks for the vids.

just recieved the pulleys from SRmotorsports. they look like awesome quality. so i will be havin them installed this week and i will keep ya posted on how they do
 
i put my balance shaft back in today and should get the FC crank pulley tomorrow afternoon as long as i catch the driver. how many pulleys in the SR kit? i know you have the option on a few, so wondering which ones you went with. i know it's a lot, but maybe try a before and after dyno as well to help people out?
 
They came with 3. yea as long as i can find someone to do the dyno out here.

Did they come with any alignment tools? If not I would highly recommend them. The 2 most important details that are overlooked is making sure everything is always DTC and the crank pully is properly installed and torqued.
 
no but it says something about them in the instructions...then again...wouldn't the shop that is putting them in have those anyways???
 
Not necessarily. Unless they've worked on a Mazda3 or Mazda6, they probably won't have the proper tools.
It's not a normal installation.
 
again, not on a 3, but the 2 local focus guys i talked to with it both ended up getting the 1 piece they needed from autozone. but i belive both of them had a tool already to find TDC on cyl #1 and a puller. so they just needed the screw to lock the pulley in place while they worked on the bolt.

But one of the guys said that air tools is a must for the install. which means i'll be driving to a friends house first and letting it cool off, or trying to get a compressor over here for the day. we'll see. the SR pulleys do look really nice though, gotta give em that.
