just curious - has anyone here broken the 200 whp mark with the dc type r 4:1 2.5" header?

 

I dont have an answer but i have a better question!

Has anyone broken the 200whp mark with a non-jdm/typer DC 4-1 header?

 

Yes to the first question. Alot of people.

 

Guess that answers my question too

 

i have the dynamic autopsorts/peak performance header..
its a ss 4-1 design...2.5 inch collector..
hit 206.2 whp

Aries tested it back when he was at dynamics...pulled better number than the dc jdm header..
but not by too much i think

 

lawnmower makes 201 whp with 81mm bore and 87.2mm stroke (stock gs-r bore & stroke) and no ITB's with a DC 4:1 JDM header. ceramic coated too (i think the ID is actually a bit smaller because of the coating) this is also on pump gas.

with my tuning

not to mention it was 90 degrees in the shop

 

I'll be shooting for at least 200 whp and I have jdm style dc 4-1 header. I would rather have something else but my funds are depleted. I'll be going to the dyno probably within the next 2 weeks, so I'll have a chart posted soon.
