/) ^3^(\ <- SO AWESOME!!
So, I'm wondering why so many K-series 4-2-1 headers have a 1-3, 2-4 (or 1-2, 3-4) pairing? And why not 1-4, 2-3?
that is some beautiful fabrication work......
i'm a newb here so its my job to ask questions. here goes
both the burns and and dtr headers are 4-2-1. is it accepted that this works better than 4-1 on the k-series? the burns header pairs cylinders 1-4 and 2-3. meanwhile the dtr pairs 1-2 and 3-4. what's up with that? thanks
i think that cylinder 1 and 4 work in tandem, that is to say the fire at the same time thus have gases being expelled at the same time, i think then this would reduce the individual pulses to only 2 at a time rather than 4 individual pulses, i think this would create more power. How? I dont know how to explain it i just feel that this would be the case, Ekasey: Correct me if im wrong on this
They do not fire at the same time they have 360 deg. of separation between then.
Zig, just e-mail me below if you would like to discuss this matter further.
Jim we have built 4:1's and Tri-y's for the K Series engines we do it per application every header is different. To tell you the truth I'm not the hugest fan of the Tri-Y but it works well when it's done correctly!
The Tri-Y header design teams up cylinders on opposite sides of the firing order as much as possible. This way, exhaust pulses fill pipes that have been empty the longest, resulting in a more-balanced flow of exhaust from the engine while encouraging maximum scavenging. There's power in this, since hot gases are not fighting each other to get out of the engine.
All portions of Burns' headers are hand fabricated and hand welded. It's this level of craftsmanship that has taken Burns to the top of the header game for professional racers of all disciplines. Few manufacturers have product at the top of all motorsports disciplines the way Burns does, as you'll find his products exhausting tractor pullers, inport drag cars, and road racers in addition to the aforementioned Winston Cup and NHRA/IHRA drag cars. They're not cheap, but they are the best.
While having a pair of headers completely custom-designed and hand-crafted for your specific application may be overkill for a street machine, Burns sells plenty of parts that are streetworthy and can add power across the rpm scale. His merged collectors can make your existing headers more effective, and incorporating one of Burns' X-pipes behind the collectors and ahead of the mufflers will reduce noise while adding even more power.
I believe his site is down. I checked the URL for the product I had inquired about in the past (from which I had his email addy from) and I also checked the main page. Both URLs are timing out as if the page is no longer available.Do u have a link? sorry to be a pain in the ass lol
Yes, he dyno'd it. It was built for an Elise, and I believe it was his personal car that was in the American Touge video. I am sure he has changed the design a few times in the 5-6 years since he posted that picture.stefan's headers are top notched
but look at the joe mcarthy one, did they dyno the header?

Joe McCarthy is his user name here, but he has not logged in since November.
