But overall he said that the with the overall package, the MPV definitely can sell. No name yet as this will be officially announced together with the winner of MPV naming contest

mpv bergerak selaju lebih 140km/ dlm full loaded (penuh air dlm kotak plastik) utk menyamai perkiraan ‘human simulation weight’.. masa test kat highway

enjin mpv baru menggunakan Campro CPS 1.6 + light turbo, chasis dia menggunakan Galvanized metal, super high strength high tensile steel iaitu lebih ringan dan kukuh/tahan lasak berbanding high tensile steel yg digunakan pada BMW 3 series dan saga baru

betul ke??

u r a really fast in admitting and correcting ur mistakes man..so nice of you..hard to find people like you in this blog man..keep up your good work..

try suggesting proton to build ceramic coated engines where the inside of the cylinder and piston is coated with a special ceramic which can retain heat and work in higher temperature..and help to produce more complete combustion..better FC and HP..and will help attract more customer to choose proton since using cutting age technology

so then 1.6 campro is really tuned or tailored for the mpv purpose, and i remeber you said before in last topic,

Cheers!

Cheers!

thanks for the info..i didnt know campro one was a ceramic based extractor…

thanks once again..

the choice they might choose is high flow cat,

i have my neo discarded the cat, the feel is quite a surge along with rpm, but not significantly torquey but the improvement is there,

about advance intake, i saw some of the dyno chart is quite realistic, interm of earlier gain though not tremendously, i do agree remap does to done, inrelation this new setting, interm of ignition, and power optimization,

like the case of increasing the compression ratio, definitely it need to be careful with ignition to be tad delay a little,

anyway the cat has it lifespan/will kaput probally at 1/3 of the life of the car, and, very expensive to replace,

but it robs accleration which i hate,

sifu, any info of campro 1.8 cps?

i wonder.. is that the same engine will powering this mpv as BONUS and SUPRISE thingy from proton? Because from the video.. i really doubt that was 1.6 engine power kind of movement for big body as that.

Paul Tan says: That was a case of reporter sesat. The moment the story came out I checked with Proton and they said they also don’t know why the reporter typo 1.6 become 1.8.

Cheers!

If ppl rly care abt mother nature, prius n biofuel/biodiesel shud b banned. Nothing but hypocritical products that kill mother nature 10X greenhouse gas amount they save.

If u still feel guilty, automotive_critics, I suggest u plant more trees or veges in ur backyard. At least, u’ll get free n fresh vege like that while reducing co2 amount in this world ahahahah. Even if u dun have space, use hydrophonic method or whatever…..used to be popular back in late 90s n early 2000s’, where u put seed in a small plastic cup with cotton nden in a water container blah, something like that la lol!!

and ah beng shop wont even know whats that..

Sifu the proton guy also told dy..haha..he knows campro way much better than me..so u should listen to him

anyway to answer ur question..extractor is the first part of the exhaust system…where u can see infront of you engine..usually the original extractor a mass production model which is made of simple bends and curves to simplify production..and this simple bends and curve will restrict the flow of exhaust gas and creat certain amount of back pressure..

but with better extractor design the exhaust gases cause flow out to the next unit more freely and this will reduce unwanted back pressure usually due to carbon deposit and all after few years of usage..so u will not loose original engine hp when u change but by changing extractor u might save fuel..and ur engine will feel more free

but there is sensor on the extractor and usually it works well on production extractor and also the connections..when u change usually like aluminium or anything else..it works in higher temperature and this sensor usually can give inaccurate reading..and mite kacau the fuel amount injected and etc..that the general problem if ppl change extractor..

ah beng shop sumtimes dunno how to weld..so if you rev a high temperature might even bocor..so dont waste much money on extactor cause its not a complicated device and dont contribute much unless a race engine..

unless u can get R3 products or expensive exhaust extractor then ok..if you thinking of cost..dont bother changing extractor..

piping and all ok la..but like Sifu said..dun eva change the muffler..the will sound like shit and will spoil the flow and back pressure of the entire exhaust system…

my advise is..always find the simple and cheapest way to modify you car..

Sifu will tell you how many hours spent on R&D of an engine..so everything they have on an engine serves a purpose..and ask advise from people who knows the engine well enough..but not from perodua engineers la..hehe..they might know how to fix..but wont know how it works…proton engineers know how to do both…

===================
Si-fu, thanks for your advice..really appreciate it.

low cam is an advance cam, and high cam remain, (although VIM is there)

sifu ,just my guess,

1) Change the extractor to a metal one(aluminium aloy or stainless steel).
2) Throw the catalytic converter, u can get arnd 4-5 hp extra. (u might hurt mother nature by doing this)
3) Change ur exhaust piping to a stainless steel wan.
4) Remain the OEM muffler (dont ever change this, very important to maintain the back pressure of the engine)
5) Change ur air filter to a better flow wan, like K&N but use the OEM(i.e the same shape with the original wan) type, not the open pod type. Too much air flow means, then u will need to configure the ECU.

Awak’s method also can, but u will definetely need to reconfigure the ECU mapping after playing with the valve timing. Many related systems will be affected by this and might create ‘knocking’ if never configure the ECU properly.

Hope this helps!

Cheers!

How about the name of this new baby..

so remember what i m suggesting to you is da cheapest way and awak suggested da best way..
