I was looking back at pictures that Mingster posted of the Spoon header he purchased... and it got me wonder about the two designs. It's obvious from the pictures that the design is different... the spoon has a much shorter '2' section then the DC headers. Can someone comment on what this would de interms of power out put?

Mingster posted the dyno of the spoon and I really low all the power across the entire power band. I hope DC didn't tune the header stictly for peak power....

Header design is tricky and fine tuning seems to be done with a lot of trial and error. It is hard to miss when you are just replacing a cast iron manifold, but the S2000 comes with a pretty good (although very heavy) factory tuned header so gains will be limited.

Both the Spoon and the Mugen designs offer power in different places compared to each other and stock. Take a look at the Mugen header/exhaust dynos to see what extensive testing got them.. a small gain through the band but not more than 10-12hp and that much only in a 500 rpm band.

I don

 

shingles you have the picture titles backwards. The top one is the spoon and the lower one is the DC header.

 

Chris is right about not being able to look at a header and see its gains. I now have the Mugen header and I think it's going to be hard to beat. Having seen the R&D that goes into their end products in person, you realize just how extensive their testing protocol is. The additional torque of the Mugen header is awesome...

I don't know about Spoon or DC's R&D, but as I said, it's going to be tough to beat what Mugen does. Remember these guys build Formula-1 engines...

Moreover, the Mugen engineers said at our conference with them, as Chris said as well, that the Honda manifold is VERY well made, except that it is a heavy piece. That's its main drawback...

I'll be waiting to see dyno's of these headers, should be interesting...

Here is a link to the Mugen h/e dyno sheet on King's site...

eze: thanks, I changed it.

I'll be going back to my dyno two more times. I will be dyno'ing the K&N filter to get another baseline with the intake and exhaust. Then I'll put on the headers and go back for another dyno session.

this may not apply to all, but the Spoon header on my car did make 12.x HPs more at the top end (and a few HPs more all through the curve) compared to my stock header numbers, and it made a difference against Prolene's Mugen header setup at a couple of points on the dyno chart. Now Mugen's setup may be optimized for mid range gains, but I can attest to Spoon's circuit racing heritage that top end gains is what Spoon aims for and got. I'm guessing that we'll see similar gain profile (compared with Mugen) on the DC headers in the mid range, but probably not the same numbers, but I'm really excited to find out.

 

I've heard from second hand that DC Sports makes the Mugen ITR header....it there any truth to that? If so, does DC also make the Mugen header for the S2K?

 

Why does the Spoon header on Pg. 93 in HyperRev look different than Mingster's pic of the Spoon header? In HyperRev, it looks like the 2 section is very long and the 1 section is shorter?
