Has anyone done a dyno on them yet? (Other then Nexus)
Days away from buying headers

 

im trying to set somethign up with them, so i may be doing a dyno on my G.

 

my opinion:

By the topspeeds or go all out and get the crawfords. The alphawerks will flow nearly the same as the topspeeds which are half the cash.

 

Hello,

To go this route is not necessarily a fully informed decision. Factors such as the following all go into making a decision on a set of header, not just price:

1. Design for installation and fitment
Does any R+D go into the product to better the designs already on the market? Small changes in millimeters make all the difference in the world on a naturally aspirated engine. The original Alphawerks header is a JDM header and would not work on the USDM model. We have redesigned with the permission and supervision of Alphawerks the header to allow installation without the "removal" or "lifting" of the engine. This is essential in that it may make a difference of over $100 in installation. Also if your fitment is off because of poor quality control you will not know this until you actually install the part. At this point you will have to pay double for install. So in the end it will cost you more if there is poor quality control and poor installation design.

2. Customer Support
Does the company provide installation instructions and full customer support answering any questions and concerns you may have whether on the phone, email, or on an internet forum such as I do here at my350z.com. How stable is the company? Are they "fly-by-night"? Do some research on the company. Look at the website, look for advertisements in major magazines. When you call the company are you welcomed by a corporate phone system and a professional sales associate, or does someone just pick up the phone in a hurry.

3. Warranty and Policies
Are the companies policies and warranties properly outlined for all potential consumers to see, such as in digital format on their corporate website.

4. Availability
Are the parts available for immediate delivery. The depth of stock is a good indicator of the legitimacy of the company. Always be sure that if you lose a part the company you buy from will be able to provide you a new one. If not, you may have to wait months for a missing piece or part.

Just FYI...hope you take it for what it is worth. These are the same questions that I asked myself when I first took my job with Nexus Industry, the exclusive NA distributor of Alphawerks, almost 2 years ago, and I believe I made the correct decision.

Very good points

 

so are there any group buys out there for a set of these headers or is there a way to set that up?

 

Good points and valid points, but in the end, the all mighty $ comes into play. I think your headers look beautiful just like my topspeed headers. My point was not to pay extra for the same flow.


In terms of the points you listed in regards to my purchase:
1.) The design is very similar to your headers and fitment was good - I did the install myself, no issues

2.) Customer support has been good. Jason at Topspeed has been great and I would trust doing business with him any time.

3.) Warranty and policy - The headers fit and this is basically the only concern. The weld and construction were beautiful and I have no doubt that these will hold up just as well as any other header on the market

4.) Availability - no issues here -

 

how do these headers make anymore power?


than these headers (DC headers):


or these headers (nismo):


or these (topspeed with jethot coating)


The nismos flow slightly different than the others, but the alphwerks, DCs, and topspeeds look IDENTICAL.....only difference I can see is price.

 

arent the alphawerks equal length.... that makes a big difference

 

If they are, then so are the DC and topspeed headers

 

Thats kind of funny, but yeah the DC and Alpha do look almost identical.

 

no, the DC and topspeeds are not equal length and they admit to that. im not making it up.

but yeah, they do look almost identical in the pictures. But i had the topspeeds and i have the alphawerks now as well. and trust, they do not look the same when you hold em.

 

Hello,

I have posted in several threads here some of the R+D pics that we had here in the development of the headers. To review the process:

1. Alphawerks sent us there JDM 350Z header.
2. We redesigned the header to fit b/c the JDM header hits the knuckle on the USDM models.
3. Once we have proper fitment, we run flow and power testing.
4. We redesign to allow installation without the removal of the engine.
5. Test once more to ensure this final design to allow for ease of install did not take away from the power.
6. Send to production.

In fact that image of the 350Z headers on our site is of the JDM header that will not fit USDM models. Since it is the JDM version that cannot fit the USDM models, it therefore cannot be the same design as the DC, or the Topspeed because they fit. The funny thing is that we ourselves have to scratch numbers into the headers because the changes that are made are in the matter of 5mm here and 2mm there which to the naked eye are very hard to decipher and even we can confuse them sometimes.

Victor,

I think people are concerned because "5mm here or 2mm there" would not make them different enough than the DC headers to be equal length. I'm certain that you guys did a great deal of R&D, but how are these headers equal length when they look so SIMILAR to the DC and Topspeed versions? I think that's what the previous people were getting at. Thanks.

Dan

 

Dan,

Thank you for the reply. What I want to have everyone here understand is the same thing that I have expressed over and over again on hundreds of posts: our headers are designed off the JDM Alphawerks headers so any similarity to other brands is due to the size restrictions of the engine bay. Alphawerks allowed us to redesign their header for the USDM market and on these particular headers we have a licensing agreement to be the exclusive NA distributors because we changed the design.

So are these headers equal length?

 

equal length..i had a set of the DC and Topspeed and they do look different from the Alphawerks

 

how are they different?

 

I'm assuming you have a good amount of information and data to prove this point and not by looking at what you have and a picture of what you don't have.

I can look at the headers and know they aren't going to flow significantly different. You mean to tell me there is that much difference in the headers that one makes 2X the HP of the other? Come on your full of it. I think the burden of proof falls you my friend.

Based on your reply I suppose you can provide data that proves otherwise? If not, then I question why you even responed to this thread.
