Type R 4-1 EXTRACTOR for sale

[HoNdA[DNA]]

I have a type-R 4-1 extractor for sale (very rare item)

4 into 1 design with a 2.5in collector... it is JDM 2000 spec... Equal-length 4-in-1 style not stainless steel laa (sorry) exhaust manifold... and the benefits are 4-into-1 layout that increases the power torque in the mid and high-speed ranges.


if interested do call me at 0126551601 (pyan)



SOLD

I thought 4-1 increases low-end and mid-range torque? And 4-2-1 allows more top-end power?

Are you sure bro ? coz i've been told differently.....

btw, i'm new here...... i would like to say hi to all.... HI...

 

[Riezal-R]

Well I'm not really a mechanic or engineer so I wouldn't really know too. But this is what was told to me during the time I was doing research on this.

4-1 = faster more direct air flow, lower presssure in exhaust system, faster response + pick-up

4-2-1 = slightly restricted, higher pressure in exhaust system (to provide top end power)

Don't take my word for it. I might be wrong.

 

[BlueG]

I do agree with Riezal-R. That is what also I have been told.

Same concept as Direct Piping and Standard Original Piping. If using direct piping you can gain more low and mid pick-up for your car, however the Standard Original Piping together with the centre bullet & silencer will maintain your top speed or your end pick-up or in the other words fifth gear pick-up.

4-1 extractor equivalent with Direct/ Straight Piping.
4-2-1 extractor is equivalent with Standard Piping.

Differences both of them is the air restriction ...

Correct me also if I'm wrong.

 

[ARe-BeaR]

Agreed with Riezal-R and BlueG....

 

[polar-bear]

yeah Riezal-R..
thts the concept..and the diff. between 4-2-1 & 4-1
4-1 better use for DRAG...

 

[Fred Joe]

if that's so.... i've been living with the wrong fact.....
thanks bros...

hi, other than type-R 4-1 extractor, do you have others part for integra?
especially for DB8.
Thanks.

waa... everyone so smart one laa.. then... this 4 into 1 layout is not for increasing the power torque in the mid and high-speed ranges kaa? actually.. MIKE KOJIMA and even MUGEN...also stated that this layout is for increasing the power torque in the mid and high speed and that's why it's being use for drag maa.. what's ur goal in the drag racing... surely for low-end.. mid-end.. and high-end as well laa... this kindda layout has led to numerous victories in circuit fields, including sepang, gymkhana, in the hands of top drivers lorr and one more thing.. for vtec equipped vehicle.. do u have probs in low-end or pickup? i dont think so laa...

i have severals books on this 4 into 1 header tech info aite...

like this laa.. go to kinokuniya KLCC.. at the automotive section got lots of books about this tech... if dont have money to buy it.. just ask the person in charge to open the plastic wrapper for u then.. u read it... kindda cool hobbies... so.. u'd better do more research aite...

actually u all r rite..

 

[HoNdA[DNA]]

by the way me myself a part time mechanic.. most of the time involve with HONDA machine... so.. it's up to u with ur perception or what so ever.. sorry if i'm wrong with the tech. info facts.. nobody is perfect... me my self i do some research on building and modifying B series engine.. and currently on my workshop's drag car... just need to sell this one.. coz we have new 4-1 header in coming.. that's all.. nothing's wrong with this one.. actually we clocked 12.313 seconds previously using this extractor... see yaaa.. thanx for ur support...

 

[aramis]

best bang-for-buck header in the market. I like it a lot coz Im using it. :)

sumthin i found about mugen 4-1 header fr sumwher:
"Description
The Mugen 4 into 1 header is among the finest of 4 into 1 designs for your Acura/Honda. Mugen headers are tuned to optimize specific engine power bands. With the 4 into 1 design, you will find the most horsepower and torque gains in the higher RPM range. All Mugen headers use TIG/Gas welds, which are superior in strength and finish to other products on the market. Also, instead of a cold bending process, which produces a tubing size reduction, Mugen uses a costly sand bending method for uniform tube dimensions. "

another tech.. info

The JDM ITR header works on the B16A and B18C engines; it has a slick 4-1 layout, which is good for top-end power over the stock tri-y manifolds. The JDM manifold features quality 100 percent stainless construction. Note the trick staggered collector for better ground clearance. It's hard to believe this is a stock piece. The manifold also has brackets for adding the stock heatshields if you want to go stealth.

High RPM yes. High speed... im not so sure.

And to my understanding, for drag is low-end and mid-range torque. Drag cars pickup fast, but loose top end. Reason being the drag strip is 400m and not 4km.

Also to my understanding, taking example from gear ratios, draggers use a close-ratio gearing. Short ratio will result in fast pickup. Long ratio will result in top end speed over a longer distance. Drag cars use close-ratio. This is the theory i know. So based on the gearing theory, drag cars are not designed for top-end application, instead they are designed for pick-up application.

This is all to my understanding and how I was taught. I totally agree with high RPM, but not so much on high speed. So to Honda[DNA], either I was taught wrong or you might have mistaken high RPM for high speed. I wont be suprised if I am wrong, as this is what the local VTEC developers teach me, not what I read from a book. And this VTEC mech's Civic EK won 1st place in the 12-hour MME 2004 race in Class C, so I trust his words as its proven on road and track.

And I myself have used the JDM ITR exhaust manifold on my B16B before. It gave me more top end but less low-end power. Reason is not due to the 4-1 layout, but instead the diameter and length of the manifold. Regardless of what my understanding is about 4-1 or 4-2-1, the JDM ITR and CTR exhaust manifold is a very, very good buy. Just depends for what application.

 

[BlueG]

Haiyooo... we all learning here. So far me myself still dunt know which one is the true. Got different pomen with different theory ....

 

[Riezal-R]

actually.. MIKE KOJIMA and even MUGEN...also stated that this layout is for increasing the power torque in the mid and high speed and that's why it's being use for drag maa..

I would definitely agree with this statement if it was mid-range RPM and high-end RPM. But if its high speed, then I'm a bit confused.

what's ur goal in the drag racing... surely for low-end.. mid-end.. and high-end as well laa... this kindda layout has led to numerous victories in circuit fields, including sepang, gymkhana, in the hands of top drivers lorr and one more thing.. for vtec equipped vehicle.. do u have probs in low-end or pickup? i dont think so laa..

Yes I agree with you. Low-end RPM, mid-range RPM and high-end RPM. Drag cars optimize the car for power at all ranges of RPM. But I doubt they optimize the car for top-end speed coz the track is so short.

like this laa.. go to kinokuniya KLCC.. at the automotive section got lots of books about this tech... if dont have money to buy it.. just ask the person in charge to open the plastic wrapper for u then.. u read it... kindda cool hobbies... so.. u'd better do more research aite...

A very nice idea, if I had more time on my hands. I just trust my mechs and other VTEC developers. If they cheated me, then sorry, I have cheated you too.

At the end of the day, we all learn something, hopefully :)

hehehe.. i dont mind at all.. everyone have their own theories.. so.. just wanna make sale here.. not to test our IQ on tech. infos... hehehe... the most impotant thing is final drive then.. without the best final drive.. u cant get the perfect ratios... that's all... which determine mid and top speed...

 

[Riezal-R]

For selling purposes, I must say that the CTR and ITR exhaust manifold is excellent. Good value if the price is right :)
