Looks nice, but is there any science behind it? For one thing, it does not look like the tubes are equal length. Second, your comment about other headers being configured wrong...Going back to the '60's, at least, from companies like Alfa Romeo, tri-y headers for a 4-cylinder configure cylinders 1 and 4 to one Y, and 2 and 3 to the other, based on the 1-3-4-2 firing order. At low speed, the second Y acts as the scavenge when adjacent (in the firing order) power pulses scavenge each other. At higher speeds. when the pulses are closer together, the first pair of Y's scavenge cylinders that fire 2 apart.

So, what's the science behind your set-up, which goes against a hundred years of convention?

 

bump on any numbers?

 

Nope, no numbers, but our converters showed up!! So we will be able to get some pic's now of the second half.

 

i am also curious. It actually looks like the tubes for the cylinders that would fire first are a little longer, so both pulses would get there at the same time, or very close to it. I would think thats exactly what you dont want. Im sure you know more about it than me and wouldnt go through all that trouble to make it this way for nothing when the other way would be easier, but at the same time why would everyone else be doing it wrong? was there any testing or theory behind pairing them this way? I really want to beleive this ways right because right now this is the best looking header on the market. looking forward to pics of the downpipe.

Edit: after doing some research on teh net I found one header for nissans that pairs 1 with 2 and 3 with 4, which I think, would in effect be similar to this header. they claimed it creates more top end, but to me that seems to defeat the idea of a tri y, so Im still confused.

 

I am also VERY interested about this, I am looking for a header/dp, and i would like to know the answer to this as well

 

Will this header be available w/ a de-cat downpipe as well? Im interested in the header by far, but if the downpipe it includes has a cat, then id just rather stick w/ my current setup.

 

And now the DP with cat!


Yes we can do an 'off road only" cat delete DP, no problem

 

didnt someone dyno before they put this on their car a couple of weeks ago? i thought there would have been some numbers for this thing already.

 

i havnt gotten my header yet

 

That thing looks awesome!

 

i got mine and have it installed. sounds awesome i will get a video up real soon. went to the track with it and in horrible race conditions still managed to run consitant at 11.3s 1000' i will try to get some number up from a dyno and a better day for racing.

 

Hows the butt dyno like it?

 

btw, is there a website for this header?

 

i dont suppose their have been any dyno results yet...

 

no dyno #s yet but track will do fine right? in pretty humid warm weather i went from an 11.12 @96 to a 11.03 @ 96 in the 1000'. so .09 i dont think is too bad in pretty crummy weather. you will see my slip soon on the 1/8 mile list.

 

I just checked Clear Image Automotive's website........I can't find the long tube....only the shorty header. Where can I go about possibly buying this header in the future. My friend just put an F2 long tube stepped header on his '07 Focus and its AMAZING!
