CorkSport Aluminum Crankshaft Pulley

Of course, your first tank after the install will have lower mileage due to constantly stomping on the gas pedal to experience the quicker acceleration.<LOL>

Outside of that, I wouldn't think that there would be any negative mileage affect. There might actually be a .0001% improvement if you drive as normal. (Musn't push foot downnnnnnnn.....AAAAARRRGGGHHHH)

I have an aluminum flywheel in my Integra and it was a nice/noticeable improvement. I would expect something similar here.

Because dealers are notorious about finding any excuse to void the warranty? Your transmission is bustificated? Must be that cold air intake you put on - sure signs of abuse. Your engine is all blowed up? Must be those aftermarket rims you put on the car - signs of abuse.

Work in a dealership for about 20 minutes and you'll discover that everything, including the water cooler, is a profit center. Warranty service, because of the rates the manufacturers pay, is anything but profitable for a dealership, and they are highly motivated to get everything the can not covered under the warranty and out of the consumer's pockets instead. Yes, there are laws that define that a dealer cannot blame things in this fashion, but they do anyway. They work on the theory that the average consumer is not as well versed in the laws as the people who post on messages boards as these are. And they are right to do so - the odds of success are in their favor. Don't believe what I am saying - sit in the lobby of your dealership some morning and watch the number of people happily paying $125 to have their oil changed and a "multi-point inspection" done on their cars...

EDIT - Bravo to CorkSport for coming up with a part like this, though. When my car comes out of warranty in not very long (I've put 11K miles on it in four months) I'll be buying one as well :)

Didn't notice this earlier. Aside from my military background, I've been in/around a dealership for 6 years (not saying much since some GM techs have 30+years), so yes, I've been there. Now on to your argument...

I don't know what dealership you've been in contact with, or going to, but I would strongly recommend getting the hell away from it. Don't believe what everybody says about a "stealership" yes, the parts prices and labor rates are VERY high in some cases. And $129 for an oil change? You work at Audi/BMW or something? We have a flat rate of 29.99 WITH a full circle inspection. It's there for a reason, to inform the customer whats wrong with there car, and to give somebody who is paid commission (ME) a chance to pay for my family. The economy is F'd up, and technicians should be making in the upper $45 per hour range, but sadly, we aren't. And as far as them doing everything to not cover it under warranty, that's a load of B/S at some dealerships, not saying some don't do it, but some do. My service manager tried to get tires and spark plugs covered under warranty today, WEAR N TEAR ITEMS! Man up, and pay to play.

Who's fault do you think it is that the dealerships try to find every way possible to NOT replace your blown piece of crap motor because you went out and took out every possible emission and exhaust restriction and "turned up the boost." Blame those sorry asses, not the parts manufactures, because most of the time their is a disclaimer that "this part may F your stuff up, in some way shape or form." I get really tired of hearing the excuse of people making every dealership out to be a bad one. It's OUR yes OUR fault that they are the way they are. The warranty is their to protect a factory car, and when you add anything to change a factory setting car IE intake, exhaust, ECU upgrade, stand alone etc etc (some crap like wheels/tires/suspension etc i don't see eye to eye with) YOU are taking full responsibility and SHOULD have to pay for your new part and it shouldn't be covered under warranty, PERIOD! I'm a huge believer or the law they just passed, but just to let you know, being in the car world and dealership as long as I have, i could EASILY convince a dealership/lawyer that an INTAKE or exhaust altered the car enough to where it changed fuel ratios or some air velocity BS story and we'd win, almost every time. Man up people, you put something on your car that alters performance, fuel ratios, how "quickly your car goes 0-60" and their going to fight. Especially with a factory car that is turbocharged. That s*** ain't cheap, and maybe THATS why labor rates and parts prices are as high as they are. END RANT!

^ lovemyrx7 works for a Mazda dealership. Can he give us any insight? I know when I had my Mazdaspeed3 I watched people get their warranties voided left and right for the most trivial of mods. I saw guys get voided WITH ONLY THE MAZDASPEED INTAKE. I love Mazda cars, but it seems you have to be very careful with modificiations if you want to retain your warranty. Maybe it's the economy's fault... who knows.

I also recall a local friend of mine with a Mazdaspeed had a transmission problem early on and the dealer denied him a loner car saying they discontinued that service. His GT had less than 10,000 miles on it at that point.

I still love Mazda, but their mod-unfriendly attitude scares me off from extensively modifying cars I still owe money on. Perhaps a REP can come in here and comment, but I doubt it.

Read above, not attacking anybody or on the dealerships side. I will personally mod my car to the extent that I willingly know warranty might not be there to cover my ass. And guys, the whole "oh I'll just throw the stock part back on there, they will never know!" isn't going to work after a year or two. For years dealerships have been able to track everytime your car has been started, fueled up, ran lean, ran rich, when you farted (not really) etc. But I've always said it and I always will...

HAPPY MODDING :)
 
It's probably not as severe with the other Mazda models. The cars with the 2.3 DISI turbo are the ones that seem to have the most failures from smoking turbos to motor mounts failing to straight up throwing rods and CDFP issues. The motor is already tuned to the ragged edge and people take it slightly beyond uninformed with bad results. The Mazdaspeed intake was a factory part. That was what was so shocking about the voided warranty.

I tend to agree with lovemyrx7. If you go nuts with modding your motor you shouldn't expect the dealer to cover it if it blows up. I would like to think something as trivial as a light crankshaft pulley wouldn't cause any problems, but who knows. I know some cars are very sensitive to aftermarket pulleys.
 
"when you farted " well that explains the hydrocarbon sensors in the seat upholstery.....

Lol...might want to lift your seats up, they have "methane" sensors in their :)

I couldn't agree more. Now voiding the warranty with a Mazdaspeed intake is a load of crap, I'd fight that till the bitter end. As far as a crankshaft pulley, as long as instillation is correct, and you don't get too crazy with it, I'm sure it'll be perfectly fine. I'm not on the dealers side here, and would gladly fight for anybody on this forum, to some extent :) Questions or concerns, feel free to shoot me a PM, that goes for anybody.
 
Ok all, just got mine! Arrived this morning and found a place to fit me in to install it today.

First impressions from the box, looks SO pretty. It felt a bit heavy, but compared to the stock pulley, it's REALLY quite light.

Talked over with the guy at the shop (+1 Downtown Auto in Kitchener!) he estimated an hour and a half to install, they called me after less than an hour, so install obviously pretty simple if you've got a hoist :-)

First impressions... Had a hard time noticing a huge difference when i started the engine, slightly better throttle response (though not as noticeable as with the SRI)... Pulling out of the parking lot, I didn't see a lot of difference in pulling away in 1st and normal street shift changes (revs <4000)... Then I got a bit more spirited, taking my shift point up to 5500-6000... To me this is where the money is on this pulley... I was able to chirp the tires easily on shifts for the first time. Quick-shifting became grabbier and tighter. It does seem as if there is a bit more available power in the low end, like the drivetrain losses are less. It was a subtle feeling though, not nearly as pronounced as the snappier shift changes.

It'll be interesting to see what happens when I kick the A/C in, because last year i remember losing any kind of power as soon as i turned the AC on! I wonder if the SRI and pulley combo will help that out a bit ;-)

I tried to get some pics, but the position of the pulley makes it really hard to get any good shot of it!

So far, seems good! I'll have to do a bit of driving this week to get a better feel for the changes.
 
Ok, so after a week and a half of daily driving I can feel the difference now with both the pulley and the SRI installed. Revs come up faster, shifts are sharper. There's definitely not as much power loss between shifts, and acceleration through the shifts is smoother as a result. The whole car feels more responsive, and less affected by having a passenger in the car.

+1 for both these products. They're really proving to be great value on this car.
