HEADER & INTAKE R&D. - Page 3 - Toyota Yaris Forums

WRLEO · 11-13-2006, 01:36 PM

I was talking about Honda's.. With some kind of VTEC.
That was a SR20 NA..

Like i said ... 4-1 heades are easy to make, alot easier than a 4-2-1.
That was my point. You dont have to agree with me..

Get me a car to run it on and i will prove it to you.. thats all. we dont need to go back and forth about these little things. Just let the dynos speak for themselves.

Like I said,a 4-1 design will be better after 4500rpm,and looks like it might be just as good in the low rpm band from that example,but remeber folks,your going to pay $350.00 for the headers from WR,plus shipping and tax,when you can pay $190.00 for the Megan headers,and low low end diffrence is not even noticable between the 2,and the Megan headers will be better at the high end,this should not be a hard choice,save some money and get the better headers,Megan headers.

Will someone in the Bay area please step up?

YamilR · 11-13-2006, 04:46 PM

I will be flying out of the country for 18 days during christmas time. I can volunteer my car but It will need to be picked up and dropped off here in Fl and off course a free header will be great. Holla

WRLEO,
I am in LV. I can be there on Sunday. Let me know if you can not find any other takers.

eTiMaGo · 11-14-2006, 02:56 AM

actually I recently read a pretty technical article (I think it was in "Turbo" magazine), about the difference between 4-1 and 4-2-1 headers, essentially a 4-1 header will give you more of a large improvement at high revs, while a 4-2-1 is a more linear improvement over the whole rev range. I'll have to read it again to get the finer points (or scan it and post here?)

*Chris07LB* · 11-14-2006, 09:14 AM

4-1 is fine with me, as 99% of my commute is steady high speed highway miles for just over an hour each way.

I just PM'd. Let's see what happens. I would love to get a header, although I've yet to get a CAI or an exhaust...

Gotta start somewhere, right?

Galavoxx · 11-14-2006, 05:14 PM

True. And if those Dyno numbers are accurate, 11 hp is a very nice start.

I hope you guys also do a stock dyno before dynoe with the header. that way we see gains by comparing both graphs.
