CPS (Cam Profile Switching) vs VVTI vs DVVT

[estear]

So, in other words, the technology is more advanced in land rover...price is also higher

Yeah, I think Campro is meant to be a 'low cost' engine. That's why it's uncertain what direction the Campro CPS-T is heading. Do they need to deliver more power or torque or both? For the entire range or just for the low revs? For sure, the S4PH won't power any muscle car...

They should only focus on the low rev since most Malaysian drive below 4k rpm to save fuel. But personally, I prefer torque for the entire rpm since I like to push it all the way to the red line.

It will be a totally new ball game when they launch the turbocharged series. Sometimes, too much torque or power will make it difficuilt to drive and bottom line, handing is still critical. No matter how many horses you have, if the car isn't controllable, it means nothing la...safety comes first afterall. They might opt for low boost setting due to reliability and wear & tear rate. Would it be manual or auto transmission for the new turbo engine?

I doubt there will be any prob with the handling if the campro is boosted at a 'standard' 0.6bar.. If its coupled with lotus ride and handling, it will be great.. I wish proton comes out with +/- type g/b soon..

Btw, Curb weight for Gen 2 is heavy, 150hp with 240NM torque should be an idea set up.

maybe add a LSD or traction control(by using ABS sensor to detect spin tyre to limit/control throttle body opening when engine over power. this oso a cheap way coz campro original come with electric throttle body). use 215/45/17 ll be help to deliver power. hope new car ll come with this option.

Even at 0.6bar, you need to know how to handle it...else, just to say good luck la.. I thought standard should be 0.5 or 0.7bar?

...not sure if you really need a LSD with 150bhp on it and 215/45/17 setting helps in terms of better traction and handling but it might affect your performance though...and the tyre is not cheap if you wanna buy branded ones.

...but power to weight ratio might be an issue with 150bhp. What I know of is that a GSR in a Waja feels like nothing and it is a 1.8L turbocharged engine. But for daily driving, it's fun though.

Normally, set up from stock is idea for daily comfort drive and fuel efficiency.
So, u will not see agressive G- force

 

[hachiroku clan]

i thought the earlier post meant something like torque steer.. Hahah i doubt the campro will be able to cause torque steer.. YET.. 0.6bar is the average, some manufacturers have higher, some lower boost.. Just wondering how much hp will it have? Circa 155hp ish?

I still prefer a modified setting For stock setup, no fun la...

Let's wait and see... I believe there are many people who are curious to know the potential too with the new Turbo...

Hi Guys,
Just wanna know if anyone had any experience on the new Proton CPS engine management?....

If compared to VVTI or DVVT, would it have any advantages or disadvantages?... how about fuel comsumption and how about the performance in terms of acceleration and top speed...?

Just share your inputs...this is an open discussion..

Hi All,
Appreciated if someone can tell about the max HP to turned up by original engine.

109whp

Hi All,

So far, the max hp that I heard from a turbocharged CAMPRO is ~170bhp. Not sure whether other sifus have anything to share...

 

[raymondchtan]

Anyway, thkx for your info!

What is your interest btw?

 

[boyzone]

will go to book CPS this weekend as look for manual tranny car.
Compared between J spec and CPS, I will go for CPS as value for money.

One happy guy on earth Not going to wait for the turbocharged version? What you have in plans for your future modifications...must be fierce and powerful....roar !!

 

[sphiroth]

Intake+exhaust = +5hp
LCP+SAFC= +5hp

Still no news for Gen 2 with Turbocharge.
if yes, I guess will hit RM65K..
Now get RM2k discount for new car.
Btw, NA could be fine for me as not so complicate compared to turbocharge.
Furthermore, most of the time is for my wife daily 100km working travel.
With 90km/h driving mode, CPS is good enough already.
I will go for power to weight ratio and some basic set up after get my new car

Just change to K&N air filter would create a lovely sound during the air intake...I love the sound very much.

Not really sure whether they would choose Gen 2 for the turbocharged platform or not. Fingers crossed, we will see something soon..

For the discount, it is RM2k now? I thought previously they offer like RM5k but I also read the newspaper that mentioned some people didn't get the rebate or discount after they pay the down payment...better ask first before anything happens.

haha..remove the spare tyre first, weight will definitely reduce much
