well, this should put an end, or atleast it somewhat lessen the threads asking what the difference between x and y headers are.
I cant believe this hasnt been posted yet, its a fucking old experiment.
http://www.honda-tech.com/zerothread?id=922589&page=1
the setup:
H22(not sure if it was jdm or not, it was in a lude.)
AEM CAI
VAFC 1
Dinan ECU chip (from 94 )
No a/c
COMPLETELY stock block and head
All headers were run open
test subjectsL
and these were the results:
1. SMSP 177.6 hp (w/ test pipe and exhaust, completely untuned)
2.Mugen 174.8 hp
3.SMSP 174.4 hp ( just primaries and secondaries, no collector)
4.SMSP 174.3 hp ( as described earlier, sniffer in collector)
5. DC 170.8 hp
6. Weapon r 168.1 hp
7. Stock ( JDM ) 166.4 hp
is a DC header really worth 4hp? weapon r, which I would say is as good as those no name ebay headers didnt do that much worse compared to the DC, especially when its cost is a small fraction of the price for a DC!!
ALL of the tests would have put out a bit more power if they were tuned and if they had a complete exhaust.
now you guys have proven tests, you decide if its worth your money to get a X or Y header.
personally, I would only get a custom smsp.
