. We will have some dyno charts posted on Tuesday at 5 PM. We want to double check our data to make sure it is accurate.


Now..is that 5 PM East or Pacific time

 

::redicting header thread to go 10 pages::::

 

http://www.automotiveperformanceengi...om/header.html

there's the link in case anyone needs it. Im going to assume 5:00 PM Michigan time since that is where the dyno took place. I more hour to wait

 

I along with everyone else am waiting with anticipation...

However, here is one thing that I haven't seen brought up yet: What are people going to say about the "fact" that each engine response differently to mods. Now I know that if header A puts down 50 more HP then header B then it might seem clear that Header A is better. But what about those 5HP differences that in can easily be a result of subtle tuning. This effect has been clearly demonstrated with CAMs.

Let the games begin...

I say 12 until it gets locked because of massive flaming

 

no more header posts will be allowed here. If anyone tries to start a thread dealing w/ headers it will be prompty locked/deleted - muwhahahahahahaha....

yoshi - who thinks he'll get hurt pretty bad if he did lock it

 

That's a good point but with the resources that were available, I think what they did was the best solution.

 

SOME PLOTS ARE POSTED NOW!!!!!!!

 

The baseline on that car seems high, was that with the SMS exhaust, or just the Icebox? (and SPOON oil cap)

edit: I see the answer now opps

Dammit, that site is banned from my work! WTF

 

looks like JD DC made 7 peak hp, and 6 peak tq, over stock, Seemed as if it dominated most of the powerband, oh well 1 down 8 to go,

Mike who has the jdm DC 4-1 but was going to upgrade depending on test results, maybe he wont have to

 

Hmm...intresting. Cant wait to see how the JDM ITR header does in comparrison to the DC JDM!

 

Thats because its a **** site. Lots of nekkid acuras spreading their bits.

We can all see the JDM DC header lost NO power, and we've all seen many posts saying "You will lose bottom end!" This test is cool, becuase it will finally put an end to all the myths out there.

 

Rea lquick...was this done o na DynoJet or Mustang dyno? I thought I read in a post that it was a Mustang dyno...but the numbers look like Dynojet ones.

If it was Dynojet..I have the Winpep software...anyone wanna send me some files

 

It was done on a Mustang Dyno.

 

wow, really good stuff so far.

 

Hmm..intresting. I though Mustang dynos usually give 10-15 less HP then Dynojet. But 174 Hp stock sounds lie ka Dynojet number to me...no?

 

Good stuff

 

I would have expected more HP from the exhaust/test pipe......
Also, why is the ITR making so much HP stock? or does it have any other mods? ice box maybe? adv timing?

NOOO...The ITR JDM link doesnt work!

Fix it please!

 

Looks like they're starting from the bottom of the hp figures and working their way up. Who'll be last?

 

I think it had IceBox and PS belt removed.

 

Hmm...the JDM ITR header looks like teh DC JDM header...dont you guys think?

Id love to see an overlay.

 

Yeah, the DC JDM and the JDM header have similar plots ... perhaps the DC has a bit more torque.

 

I think it's important to focus here on the ratio/relationship of stock hp VS brand (X) header hp; as opposed to the actual HP figures themselves (ex. 174hp stock)
This will give you a better idea of the actual results of the headers, and less headaches.
