[Top Speed]

I am going to start by saying that we are completely unfinished with our header testing. We have not been able to test as many designs as we would like, mainly due to the fact that we have been extremely busy and do not have enough time to devote to it.

About weekly I see someone comment that the SVT header is the best of the best. Well sorry to say that it is not. We saw a good amount of gains on our test mule over the SVT header, which frankly is what I expected.

The only thing changed between the two runs was the header. I plan on doing even more testing in the future, but this is a good start.

We saw a 10whp gain over the stock SVT header. I feel like gains will be even more on a more powerful engine, such as a supercharged or high compression n/a build.

Nice gains! So what do the headers look like in their current state? Or is it...Top Secret???

 

[Buickboy]

was this stock header and cat VS yours or SVT header/ORP or high flow cat?

awesome gains up top [thumb]

 

[Top Speed]

Both headers were tested with no cat.

very nice!!!! svt header seams better down low, but i'd be willing to sacrifice. how much will it be????

here are some pics of our stainless steel version, the one currently on the car is the same design only it is mild steel.

We are still working on the pricing. We will probably offer several different versions.

am supercharged! I would love another 10whp out of my car!

So you are saying that if I run your header and intakemanifold short runners that I could possibly gain 20 whp with my current setup? 187 whp sounds good n/a lol

What are you particular mods so far?

 

[DEMENTED SVTF]

AEM full cai w/ itg filter. CFM 67 mm tb. CFM exhaust cam gear retarded acouple of degrees. Fswerks udp. Mild port n polish head. Jays racing 2.5 orp into stock Svt exhaust w/ lunch box delete. Fswerks tune. This is the setup the last time I dynoed. The only thing I've changed is I went with fswerks 2.5 stealth full exhaust which I feel a difference with my Svt large muff was pluggin up.

Now that's what I like to see!

id like to know if any kind of tuning was involved in the before and after dynos,[???]

 

[DEMENTED SVTF]

Bump is it available yet highly interested

The 2 graphs were stock header with orp and TS IM, and TS header with also TS IM so I would asume it was tuned both times.

 

[DEMENTED SVTF]

I don't think they tested both together. I thought it was the header change only. I could be wrong

 

[svtguy88]

I'd certainly be interested in exactly what changed from run to run on the dyno.

It seems odd to me that after years of the SVT/Cosworth designed header being the holy grail of exhaust expulsion for us Focus enthusiasts, that there are now two (potential) options that offer double-digit whp improvements...

 

[DEMENTED SVTF]

The Svt header is 4-2-1 topspeeds is 4-1. That could be the difference

no one else ever wanted to build and do testing on the zetecs. FSwerks abandon the zetec when the duratec came out.

That is a very nice header!. I'm impressed to see the merge collector, great job.[thumb]
