Pulleys from srmotorsports.com
- Thread starter BC3I
- Start date
been talked about before. SR is kinda weird with their products. check out the dyno's....who's starting with 118hp? ....and same dyno for the 6??
Walter from MarcyMotorsport as well as Ricardo from FR Focus, said to stay away from pulley on this engine until it can be looked at more. doesn't look promising in the long run.

I'm sure they have said that because of the detail needed to do the install.
With the right tools it is not hard to do and will produce good gains. So far there have yet to be anything to suggest them to be harmful in the long run, besides opinions. But that is the main reason they are not interested in them.
Not everyone follows directions to the "T".

$400+ is a little expensive for trial and error, especially when just about every other underdrive kit is half or quarter that price.

Did you bother researching anything before voicing your "serious doubts"? Or are you just up to your old "because I said so" tricks?

I know that earlier Mazdas, while they'll benefit from gains, the downfall is that the UDP underdrives the oilpump and it would eventually fail....i'd say that's a big side effect.
I have no idea how the 2.3L is setup, so it may not have that effect at all. But thought i'd mention it.

400$$ is for all the pulles not just the UDP though... but the UDP is the one that can cause the most problems and would be the hardest to do... i believe there are 3 total.. udp, ac, and water...?? i could be wrong though...
i see on GW's links that those kits include all pulleys as well for 100-150$$ less then the sr kit... so there you have it... over priced...

if you really want a UDP you can just get the FC one for half the price. Walter had UDP's on all his cars except the 2.3's as he feels (he's installed plenty, he's not lazy). he hadn't looked at the 6, but says a for sure no on the 3.
yes the install is the "hard" part, being it's precise. can it be done with the right tools and skilled machanic, for sure...but some pros feel the after effects are far from worth the benefits.

Walter says no, no because the Focus pulley and the Mazda3 pulley are very different. Focus only uses one drive belt, the Mazda3 has the drive belt and the A/C belt.
So the FC one will not work unless you are going to remove the AC compressor or belt.
Anyone that has ever installed cam gears or cams on the Zetec Focus will know how to install UDP's on the Mazda3 or Focus 2.3L it is easy and basicly the same. You use the same tools.
But there are still no facts to back up the claims that the after effects are far from worth the benefits. Only opinions.
Talked with UR about a year ago and they wouldn't touch it unless we had 50 lined up. gonna be a while for that.
Az, Walter has a 3 as well. that's why he started on the mazda stuff. he won't put the pulleys on ANY of his 2.3 duratecs....focus or mazda. the install is the most critical part, but even though it can be done, he believes the pulley is a bad idea for the longevity of the duratec. i really trust his background as he's had a couple things start with him and are now being produced by cosworth....who has every power adder for the duratec you can imagine now....but no pulley set?
What i'm saying is i don't recommend anyone trying to grab these as people in the industry avidly stay away from them on this engine. if a company comes along, as i said, running these things hard for a while without ill effect, cool. but let a reputable company do it, don't be the guinea pig since SR put it on theirs (who's only put down 118hp stock?) and say they got great benefits.
If you look at the older threads, i emailed SR as well as left a phone message that i would drive my lazy ass up to norcal to have them install these things for me, and i could to a write up on the install for those interested.....yeah, the don't return emails or phone messages anymore now for me.

Walter has a 3? Hmmm I have talked to him many many times and offered him to use my car. He even offered me stuff if I could find a Mazda3 that was closer to him.
And he was even using my friends car in SD to make the intake.
I have heard him state that he doesn't like the pulley, but there is just no evidence that it will do any damage in the long run.
But I agree with what you are saying about SR. But I just haven't seen anything that states the UDP's are bad, especially when there are a few with many miles on them.
depends on the product and the engine. Focus Central says their pulleys are fine with FI, but not in combination with the BS delete. Marcy has initial #'s from his all motor setup with his BS delete as well as the pulley from FC from last year, but don't know how long that held together. the problem with the 3 is it uses multiple belts, so the FC pulley is of no use at this point anyhow. there are quite a few zetecs running the FC pulleys on their blown focus', but again, it's a different engine.
