This is what the primary lengths should work out to per ID:

1.625 = 37" primary length (4,500rpm@500*F - 6,000rpm@1,000*F)
1.750 = 31" primary length (5,250rpm@500*F - 7,000rpm@1,000*F)
1.875 = 27.5" primary length (6,000rpm@500*F - 7,000rpm@1,000*F)

Those lengths are based on exhaust temp and wavelength (quarter wave).

Basically, the lower the EGT the shorter the primary length needed and smaller the ID. The higher the EGT the larger the primary diameter needed and longer length ... to keep the same velocity in the primary, in our case ~ 1,037FPS.

So is this dead already?
Who do we contact for pricing / what is pricing?
When will they be available?
Should we expect to see a dyno on something in the near future?
What material is the header made from?
etc ...

Like I'd mentioned, I'm in the market for something new right now.

I might have to inquire based on how my tax returns look. I have nowhere near enough motor to need something like this but Ive been stockpiling parts for a 2.3 build down the line.

In my Opinion it would be better to test this on a stock motor as this would be the only performance modification above stock. A gain is a Gain weather it is on a stock motor or on a fully prepped NA motor. If you could see a gain over a svt header in stock form then you would most likely see a large gain in a fully built setup also .

No offense dude but you have a piss poor attitude! No I dont have a full built na monster! Yes I am completely stock! I have the right to post here just as much as you do ! the way I describes would give me the results I'D want to know about. Im not knocking anyone down in any way. It looks like a quality product but id like to see the results for a situation similar to mine. Bullshit post like the one u just posted are what clutters up the forum because it is an absolutely useless remark. If you dont like what I have to say then dont read what I post ,its as simple as that.


TopSpeed, When you start production of the header will there be a ceramic coating option?

*edit*

Why would you want to see it on a stock engine though? It's not what it's meant for. A stock engine would most likely see better results from the SVT or JBA header. It's like asking to see how a (insert huge turbo here) would work on a stock engine- it's not what it was meant for and would most likely show poor results when compared to the properly sized part for the application.

I know the OP says it for a Full Built NA but shouldn't their still be a gain on a stock motor also? The reason I asked what I did is the fact that I would prefer to buy a header only once . I dont want to have to purchase a svt header and get to a point where i will have to buy a different header to see more gains. Id rather do it right the first time if that makes sense

there are many parts that work good on some combos and not at all on others this header wont lose power on a stock zetec but something with a 1.75 primary is meant for high rpm high power...

the svt header on a stock motor would likely make more power all around except for the last 1000 rpm... the best upgrade to go with this piece would be raising the rev limiter with a tune. A very nice and solid piece built by top speed but it is one of those very niche markets where guys are only doing it for the last 1-5 hp they can find once everything else has been done....

a very high boost centrifugal SC will ebnefit from this time and time again
