btw, 5 valves per cylinder was develop by toyota!. hehe ..nothing to do with the lotus... lotus use toyota engine to tune and do other stuff only.

5-valve per cylinder isn't from Toyota, it was joint develop mainly with Yamaha.

Btw, 5-valve per cylinder already in racing engine some time ago before 4AGE using it. But the pros for 5-valve cylinder doesn't give much advantage over 4-valve relative to the complexity introduced to the engine. That's why most racing engine now still settle for 4-valve cylinder.

oh, i thought the one and only way to support proton is buy their cars

Not really. You buy foreign cars which already imposed some hefty amount of taxes to the Government. And the government supported Proton do get benefits from it. But no one in public knows how much help do they received from the Government.

so dude, explain to me why i got a near flat power curve on the latest batch of Gen2????

Did you dyno it? Or just simply said it out just like the Proton brochures shown to us. Scan your dyno page and show to all of us if you dare and prove us dead wrong. Otherwise it is just another baseless assumption.

oh, i do wish to, but currently i got limited access to internet since i'm at my new home and I cannot upload the chart yet. once my internet connection is restored, I'm more than willing to post it up.

so it might be a while for me to get my streamyx....

That good. I'm eager on that chart. I found it weird since that engine were able to tune towards near flat torque curve (an advantage), I wonder why Proton not doing that as factory default, instead of the less practicle setting (or is it they already did that on newer batches?)

Without the graph, from the time being, the flat torque curve remains a myth. And I think it shouldn't be used as fact for the moment.

Regardlessly, should Proton slap on a supercharger on Gen2, I think it might reach some sweet spot and bring in some more enthusiasts, an interesting scenario (Gen2 vs GTi) in our local motorsport.

Here's the torque/power graph from Gen2. Source: http://www.geocities.com/robyndigital/charts.htm

The red line is claimed to be the stock before modding.
The green line is after modded to have better performance and wider torque curve.



From the chart, the stock Gen2 torque curve is terribly in the wrong range.

Where you tuned ur gen2? How much?

Please refer to the source. I'm not the owner of the charts and car. tongue.gif

I won't be owning any Proton unless there won't be any more comment on cheap plastic, power window, door knob and its overal quality as a comfortable reliable practical car. And I don't need any high-revving engine or racing kind of turning corner.

So the engine generate more heat and need careful cooling. Btw, how much is the total cost for all the changes, tuning and flushing?

This rule does apply to all campro engines.

You mean this only for the Hi-Line version? I mean, is the Campro engine differs with the Hi-Line and standard version?

I have to clarify that the VIM is done on "emulation"

As of your claim, I think every engine do have VIM afterall.

So Campro engine looks like a plain vanilla 16-valve DOHC but with high water temperature.

One word - dangerous.

Most likely you might spend more repair cost on new Waja than a used City iDSI.


Anyway, with Waja body and Campro characteristic, anybody try that before? How zippy it goes?

Honda City has max torque 131Nm at 2700rpm,
Campro has its torque 107Nm at 3000rpm, max torque 129Nm at 4600rpm (from chart).

About same concept as VVTi.

CPS are suppose to be like VTEC, the cam profiling as in cam lifting. VVTi are cam phasing, but still absent in current Campro. There are report saying Volvo used it (the Lotus Campro engine with Campro)? But I really have hard time googling for it. Anyone have links?

And VIM are suppose to be like TVIS of 4AGE in which Toyota later get rid of it on its latest generations.

Reality is that all the real-life Proton Campro engine (fitted in Gen2 and Waja) shows mediocre torque in the low-end which is entire against the claim in the Proton site. Until Proton does have it, it is just brochure grade information.

when you are fast=your fc also fast lah.......

You try going 20km/h. And I do 80km/h. See who have better FC. tongue.gif

any car wanna play pick up/drag also consume higher fc.

That's not the point here. The point is, given the same driving pattern, which one having lower FC.
