Hey guys, I am the first one to have the alphawerks headers on my 350z. They need a 350z to test the headers to make sure it will fit right and to see how much power they would make. So I was the guinea pig. Well every thing worked out great. They did a before and after dyno and let me tell you big difference. Fitment was no problem, but install takes like 4-6 hrs. To see the dyno go to www.nexusindustry.com and you will see my car. They also made a video clip of the car on the dyno. The car was stock before I did the dyno, and now I have the alphawerks stainless steel headers, and I want to get there test pipes. The bottom line was that it made more power than the dc sports and stillen. I was in shock!!!!!! Super street even did a write up on these headers. Its a bang for the buck.

I paid $515 for my last stainless steel header (just one thankfully) on my Spec V, so I guess $1100 is good for two headers...makes you wonder about saving up and getting FI

I am finding it impossible to believe that you gained 21 hp and 15 lb feet with no otehr mods except the header unless they played with the dyno values between runs. I just don't see those gains coming forth on an otherwise stock NA V6 motor.

looks like nice welds on them though

222hp stock. I wonder if they played with the dyno values???

sounds like they had the test pipes and headers when they did the dyno

even with test pipes I still dont believe a 21 hp gain.

Let me put it this way, you can never trust a dyno unless you do a before and after run at nearly the same time under the EXACT same conditions; temp, humid, etc. It has been proven that you can make 10-15hp just by making the air cooler or simply turning the fan speed higher. You simply need to buy an item by the craftsmanship and concept that they produce. If a set of headers is SS, had good welds, is equal length, and has good bends; then you really cant differ much in hp from one good set of headers to another.

ummm, yeah, what says it's not HIS company? And the company car? There is no way that ANY set of headers is going to make that much of a difference alone on an other stock N/A Z... NO WAY!

I think they messed with that first number because as stated before, that 222 hp sounds a little low (if it's a 6mt Z)

Remember how they once said that honda's couldn't run 9 sec. all motor, etc. etc. But all I know is that I was there and saw it with my own two eyes and I saw the welds and everything first hand. The problem is that I am not a car expert and no one here knows what goes into R&D of a product. But these guys put the product there and backed it up. I am going to contact nexus and see if they can come onto the forum and answer any questions for all of us like I said b/c I don't know the first thing about R&D, but these guys were cool with me and answered all my questions so I will see if they are willing to come onto the forum...

Hi,

I'm curious as to what type of dyno it was?

Thanks,

pretty amazing too that the poster posted on another board (I believe the same day as this thread was starter) and asked "has anyone seen these headers, I just read about them in Superstreet".

Why would you need to read about them in Superstreet if you had them?

Gary - I say it's a WTB Dyno - Wishful Thinking Brand

There on eBay right now for $700. I don't know...I must say I was a littled tempted. Apparrently they will go up to 1100 when the shipment comes in. They are SS, equal length, JDM etc. If they are as good or better than Stillen or Crawford then 700 may not be a bad deal. That's a big IF though.

I need to go to that dyno

PhoenixINX

... I could say I do, as does the entire Crawford team.

The blood, sweat, and countless hours Doug dedicated into trying to make a set of headers, which in time would be recognized as the most premiere available makes ANYONE a believer.

Then to be one of the first to pilot Dougs car with the prototype set installed... Yeah, I know what REAL R&D is all about.

Some people make them to fit, and to sell.

Others make them to fit, and to perform.

Enjoy what it's all about...

What is "JDM" about them other than the magazine makign reference to the term? Furthermore, how does that make them any better?

Stick with the headers that have been proven to perform guys

Phoenix - the Crawfords do look sweet and might be my choice for the heads we end up doing (looks like I need to find another set of heads so maybe Doug et. al can help out there!). Only thing that concerns be somewhat is the lack of a plate across the runner section where it mounts to the head. I know every other header out there uses a continuous flange, though I am not 100% sure which method is better

I just meant that they are imported from Japan(says on their website). Doesn't necessarily make them better but they could be as good or better.

We wont know until someone tries them. Of course, by then the price will prob be jacked up to normal and they wont be such a good deal anymore.

They do look and sound good from the picture and description.
