If you don't mind doing a favor...
See if you can get a dyno sheet for their Mazdaspeed FS intake cam, along with lift/ duration, and whether or not lightened retainers/ stronger springs are required to prevent valve float at high rpm.

 

you do not need valve springs or ret if you are going with the mazdaspeed cams , i have installed 3 or 4 on guys cars and not one has had any trouble as for dyno #'s i would say 7-9hp to the wheels with them

 

ya no problem, it was taking me a lil longer to get that email off because i didnt want to go on their site and figure out what i wanted to ask the question about to begin with haha...

 

Well, I take it no response from Cork Sport still. I think we should change the subject in this thread from "These guys have everything" to "These guys will sell you anything".

Got five hundred bucks laying around for a Auto EXE throttle body? How about nine hundred for a header? Oh, and by they way, they say it'll make your car faster (though nobody can prove it).

 

ya i haven't gotten a response back yet, interesting, i've never had any troubles with them before... the only difference was that i was buying parts for my probe, not a protege, but i dont see that being a factor in whether or not they give quick/informative responses...

 

i just wanted to follow this up again, i was looking on corksport again (just getting ideas) and noticed that a couple of their products DO include links to dyno plots now, just FYI...

 

oh man, my ******* started bleeding when i read $500+ for a freaking throttle body!!! dear god!!! LMAO!

 

I bought a whole intake manifold and 65mm TB for my pinto for $300+shipping!! Mazda's aren't cheap to mod (well)

 

You're right, Mazdas are not cheap to mod. But five hundred bucks for a TB is highway robbery. I've seen them on E-bay recently for less than two hundred a pop. Provided it's somebody's project, and I have no idea how good or bad the workmanship is, but if I was going to do a TB I would take the chance on the E-bay unit first before dropping half a grand on the Auto EXE unit.

What's more, from what I have seen and heard lately for other cars, changing the TB will not net you ANY gain as long as there are other restrictions in the intake. It might feel slightly faster due to the more sudden tip-in from a wider throttle opening, but actual flow won't be much better than stock unless the intake manifold and MAF are opened up.

That's why it would be nice to see hard data from Cork Sport. They claim that a larger TB will net more hp, but there aren't any numbers to support it.

 

generally, a larger throttle body does very little to up horsepower on relatively stock engines. they do, however, greatly increase throttle response. but man, they want an arm, leg and a large portion of my lower gall bladder for half the **** on that site.

 

true, but look at it from their standpoint, corksport is not some huge corporation, afaik they are a small company more than likely run out of a small shop or garage somewhere... they probably dont sell as many products as they'd like, and to be honest development and production of peices like this DOES cost them money, and then they need to make a certain amount of money off of each product, and if the product is of a higher calibur than say an ebay product, it more than likely costs more money to develop... i have never received anything from them that was even close to sub-standard, all parts have been top notch, and personally i enjoy throwing the little guy some money as opposed to another company... and its not fair to compare their prices to prices being given for completely different cars, because mazda's ARE one of the more expensive cars to modify, if for any other reason than lack of an aftermarket...

an example i'd use for this situation is PRD (probesport racing development), they sell many products that you can get off of ebay as well for cheaper, but the PRD parts are a lot higher quality and just generally nicer, so i'd rather give the money to them than some random vendor doing business over ebay with whole-sale items :shrug:...

i dunno, i can understand the complaints about lack of information (which they have started putting dyno sheets with some of their products, which i mentioned above), but i dont really see anything terribly wrong with their prices, high prices run hand-in-hand with cars that have small aftermarkets, if you wanna spend 100 bucks and get a **** load of mods go buy a honda and shop at autozone, otherwise start shellin out the cash ...

 

I don't agree that a ton of money needs to be spent on these cars. Nine hundred bucks for a header? Five hundred for a TB? But hey, if you see it like some kind of charity, then go for it. If you suggest that I spend a ton of bucks too, then convince me that Cork Sport's nine hundred dollar header is better than a Forza/OBX or a Wagner. And, try to do it without a dyno sheet.

 

no not saying that at all, but OBX is quite a big company, bringing in A LOT of money, with people on hand every day to design new products, so it costs them virtually nothing to develop parts like that, so they can sell them for cheaper, and quite possibly at better quality/more gains...

i guess my main point was that for a small business (like corksport, PRD, rr-racing...) high prices are not that uncommon... dyno sheets SHOULD be provided if they are going to claim a gain in HP, i do agree with you on that for sure, if your going to say your part does "this", then have some kind of prove that it actually does...

and the other thing is the dyno plot for the car they test it on might be different than your car (every car is different, factory freaks, lemons...), their car might have mods X,Y,Z, which enhance the header better, where your car has mods A,B,C, which may hinder the performance of the header... so for a smaller company that doesn't have a dyno on hand it is harder to keep going back and paying an arm and a leg for dyno time to test each individual part...

i dont want to turn this into a fight or anything, because i do agree with you for the most part, claims in performance need to be backed up, all im saying is cut these guys some slack, personally knowing the guy who runs PRD gave me a totally different veiw of a lot of these internet vendors, most of them are just guys that build parts in their garage, no customer service dept, no performance shop and so on, so i tend to try and not be to critical of some things when it comes to them...

 

Small companies make their living on word of mouth advertising (satisfied customers) and their reputation amongst its customer base (high % comeback customers). Larger companies make their business by giving discounts, fast shipping, and commercial advertising. Customer service at a larger company is most always less personal due to the nature of their business, selling bulk cheap and hiring as few extra hands as possible to make these prices feasible. The problem I see here is that cork sport is, yes, a smaller company and thus will have higher prices. However, they don't make up for this with their customer service. In certain circumstances, I'd rather pay the extra cash knowing that I will have a better buying experience and more customer support. Sometimes with the smaller companies you can even build a personal relationship with one representative who knows you by name and has a repor with you, but from what I gather, I'm not the only one who's had customer support issues with this company. That tells me they don't have the advantages of pricing from a larger company, and don't have the advantages of good support as a small company. So I ask, why would I ever want to shop with them when I can get equal levels of support and lower prices, or better support for the same price.

 

if you think, for any reason, that $540 for a throttle body is reasonable... or that $500 for a carbon fiber air funnel is reasonable... or $900 for a tubular header is reasonable...

well hell, apparently anything from AUTO EXE is out of this world. if i buy a throttle body, they better ship a fresh rock of crack cocaine and a tube of astro-glide as gifts!!!!

$34 for a muthafuckin' T-shirt! jesus!
