[jackylsp]

Hi all BT20V sifu,

Anyone can advice whether you have try this custom 4-2-1 in your black top ?
http://www.te20v.5u.com/photo6.html

the stock BT 4-2-1 extractor having worst torque in low and mid rpm.
refer to my dyno torque graph

i heard that this custom made extractor can help to distribute the torque more equally.
im looking for some one (northern region) who can help to custom made it.. if you have friend please let me know.

How come your Run 2 so much difference? Extrator?

 

[lkeong88]

How come your torque curve seems abit weird? I thought it should be quite flat for 20v? I dont think you can fit such extractor under your ae101? You will be hitting on bumps? I think in the north there is one called Chean Exhaust that can help you

bro jacky...

i guess u are driving ae101/111 corolla with 4age 20v..

but the picture show is tarik belakang 20V woh. i dun think can match ur car on this custom...

btw.. if ur budget allows... i advised u can go for aftermarket extractor from Japan(used item )

like HKS, FGK, RSR, or etc..4-2-1 or 4-1

i guess result, quality and finishing shud be better than the 1 in picture...

Yes. my car is AE111.
how about item below ? MANDREL BENT CHROME EXTRACTORS
(WIDE RANGE) 4AGE 20V

Well...just my 2 cents on the CO2 sensor la...errr...i think standard aftermarket headers like RS-R or Apex'i has their reason for the right calcutaion for the sensors to be install at that default place...by moving the sensor too much to the front up....don't think is a good idea...
From the link you show us....that is actually a setup for a RWD ...so i also think that the custom setup is not quite suitable for FWD 4AGE.... if u do notice...both RWD & FWD header length calculation are very different...
Correct me if i'm wrong... just my dua cent... don't shoot me... i'm using RS-R 4-2-1 cheerss...

 

[TRD.AE92]

Ermm... Any gain from the one you showed to us?
I never done this before, but normally I only change aftermarket extractor... and never go to ask customize for it.. I know it should be different, but how it different?

where did you get the cusco extractor ? it is make your torque curve better (i mean low and mid range) ? btw which type of muffler is best (Straight or S-flow) im using S-flow now, they said S-flow will worst in high rpm.

I'm not sure is it better or not, that's why i ask you to stack my graph vs yours and compare. I know you are a frequent customer there . Just ask ah Loy for my graph and say i gave consent for this green light. Nothing P&C on it :)

Cusco Extractor with kakimotor full set (Straight flow)

Let me know how is it compare to yours, eager to know too ..

Hi may i know what you "mean tarik belakang 20v" ?
below are my car setup during the dyno.
setup:
1) stock BT Engine
2) Using Ron95 petrol
3) stock plug cable
4) Open port Apexi filter
5) Sars fuel regulator
6) Custom piping 2.2" with lousy S-flow muffler
7) iridium plug
8) Idemitsu 10w/40 already run 2000 km since conversion
9) Piggyback Unichip-Q

im doubt will my torque become more flat (better in low,mid and high rpm) if i change to aftermarket 4-2-1 extractor and straight flow muffler ?

Tarik belakang means Front engine, Rear Wheel Drive . Just ask ah Loy for the gold SEG graph. If he don't know, i go there n smack his ass.

hi bro jackylsp...which part of sp u r from?

 

[AE80TypeD]

I dynoed my stock BT+stock extractor & got the same curve shape for torque. its normal bcoz of the VVT operation. however i also wondering if extractor alone can "flatten" or change the curve shape a bit. my logic says no, but im no expert.

i dont know if 4A can have flat torque curve at low to mid revs. 'tis the sad fate of all short stroke engines. 7A... now that may be a different story >:D

hi bro jackylsp...which part of sp u r from?

Hi. im stay at Laguna Merbok.
