always bash proton. bash proton. if u have the knowledge takpalah. maen cakap tapi degree dalam arts,photographic, mass communication jer payah lah bro.

Cool!

nice

And I'm really skeptical about the Kleeman thing.

I hope you can allow me my entitlement to how I feel about this……

Lotus Tuned, to me, is a gimmick, I agree with 5elements, but I'll say one more thing, its a gimmick that works, seeing how some people are entirely sold.

And again, I'm not a car engineer or expert, if you find my description of supercharger wrong, puhleease excuse my ignorance. I merely wanted to ask if any forumers here have heard-of or even used the electrical driven supercharger/kompressor. I believe my knowledge of the "supercharger" is accurate.

I never mention anything about boost because unlike you, I'm not as learned as you.

"Btw, back to the topic also, the “”slow”" operating speed of a turbo that you mention is approximately 20,000rpm at engine idle speed, which is usually around 800-1000rpm, engine speed"

You have all your numbers. I know an F1 engine's TOP RPM is around 19,000 to 20,000 rpm. TOP RPM. An ordinary car idles around 800 to 1000 rpm, true.

I meant slow operating speed was… in order for the turbine to start spinning in a turbo unit, it needs the exhaust flow to generate enough force, right around a minimum of 3,000 rpm. Some bigger turbo boost units operate at 4,500 rpm. Most turbo units only starts boosting at a minimum 3,000 RPM. The time it takes for rpm to reach boosting level is called turbo lag, and some cars take forever to reach that level.

Hence some manafacturers prefers to use supercharger instead, which compresses intake air immediately at start-up.

I think that much I know la…

for a start, you are mistaken to think that "quality" has a bearing on car handling.

you also insinuate that a satria gti handles like any other "standard road" car.

what do you use as a benchmark when you mention 'standard road' car?

Btw, back to the topic also, the ""slow"" operating speed of a turbo that you mention is approximately 20,000rpm at engine idle speed, which is usually around 800-1000rpm, engine speed.

What you have mentioned about turbos is also a misconception.

A car running a smaller turbine, with lower boost will also have no apparent feeling of "lag". btw, most supercharged standard road cars run very low boost pressures.

Anyone hear that there are actual electrical driven compressor/super charger units? I first discovered it looking at ebay.com.my and later googled it. Sure enuf, there are such things developed especially in US. Much simpler to use and install, connects straight to the air hose and fuel distribution unit. Runs on electricity so don't need actual engine power to drive the belt that drives the charger. Assuming that you're familliar with how a superchargher/ kompressor works, it uses the engine, thru' an extra pulley that drives a belt connected to the compressor unit that compresses air and injects this compressed air through to the fuel distribution unit, forcing more air to penetrate into the combustion chamber and faster. Turbo works in simillar fashion accept Turbo doesn't need the engine's power to drive the pulley, and in turn drive the compressor…. Turbo works by running the exhaust flow thru' a 1 turbine that will do the compressing just based on basically a waste product, the exhaust flow. But what the turbo lacks is operating speed, whereby most turbo units can only start compressing at 3,000 RPM and above. Whereas a compressor/supercharger runs from the moment your car starts (because it's driven thru a belt connected thru a pulley, connected to you running engine. So the compressing starts right at the beginning.

Scientific reports show that these electric compressor works (of course also drawing electric power from your car, unlike turbo) and do have observable improvement in dyno tests and road test. The problem therefore is knowing the limit that your car can take before it burns out or meltdown (warning to you speed demons that push your car so fast and so rapidly up the RPM). Also, they found that initially the fuse kept blowing.

So, has anyone heard of this electric compressor/supercharger? Or has anyone here tried it?

BTW, CAMPRO has so far proven another gimmick, the one that Gen2 has, have absolutely no cam profile differentials in it. It's just another 1.6 DOHC, basic albeit slightly powerful engine.

Many may be impessed with "Lotus Tuned", but ask yourself, this is Proton you're talking about, with Proton's standards (and you know what I mean), you can have Ferrari, winner of the last 6 consecutive constructors championship in F1, Tuning for Proton,…. geez, on a Proton, I'm not impressed. Sure I agree that there's plenty of science behind developing road handling, you have to admit, if the package sucks to begin with, ie. chasis, material, design rigidity of car, PLUS infamous workmanship and finishing….. there's only so much Lotus can do. They came out with a good compromise design, based on all those sciences, finish product is not their responsibilty.

Sure Proton is using the slight design change planned by Lotus, by any usual Proton standards, you do the maths on defects, recall, workmanship, end product quality…. means you'll probably have to minus off some percentages here and there, what do you get….. Probably as good as any standard car la.

Let's face it, they have a HUGE quality control problem which they unofficially acknowledge thru mechanics who says."Standard la!!" whenever you have any defects or problem…. Take all those things into consideration…. Lotus Tuned- How much is that worth? Gimmick or real scientifically improved handling on you standard STOCK Proton. What are the odds?

I think it's a gimmick. And GOOD GIMMICK too, because it works to some extend, obviously many people here are thoroughly and steadfastly impressed.

Chiaou!!

hi quest, you have made very good comments. but i still do not agree that ah seng keong(no disrespect to our local mechanics, a lot of them are good friends) can do a better job with suspension tuning out there than properly qualified and experienced race engineers.

REmeber also, a race car and a road car are 2 very different things.

take a look at this years MME as a gauge. the winner in the 1.8 class is a proton putra. but it has an all australian driver lineup. although the mechanics, and the workshop are local, the people who work there have an intricate knowledge of suspension tuning as well as working closely with the drivers to setup the car.

Same goes for the R3 tuned Gen2. it might only have 150 horsepower at the crank, but it managed a 2min 39sec lap time. this is a super quick time, beating many honda vtec civics. Its the first time also that a gen2 has raced in sepang. The car isnt the lightest, or the most powerful, but suspension tuning and car balance was a priority.

the satria gti might not be the best production performance model from proton, but it was a first for them. that tag now belongs to the satria R3 in my opinion. Honestly, how many cars on the road, brand new in malaysia, can handle so well on malaysian road conditions out of the box within that budget range?

also, chassis stiffness is in the eye of the beholder. a race car? sure its stiff, the roll cage done properly sees to that. road cars are not that easy. too stiff, and ride suffers as well as crash worthiness. Modern cars are designed to be both stiff and flexible where it needs it. same goes for the suspension setup. how hard, how low.. what are the road conditions.. who are the target market..etc. its a fine balance. and the stiffest, lowest, or hardest spring and damper setup does not make a "good handling" car.

just curious, when you mention that the satria gti wasnt impressive on the handling dept. what exactly do you mean by that. what are the details of your drive.. also, what is your benchmark car when testing the satria gti.

Perodua is owned by Toyota by way of Daihatsu owing 51% (majority!) of shares in Perodua. Daihatsu, in turn, is owed by Toyota. It’s a normal corporate structure, everywhere.

By saying ‘Lotus Tuned’ is just a gimmick is same like saying proton bluff, lying to us, which, I don’t agree.

I own a gen2 hl and I’m very satisfied with the ‘stock’ handling and so do a lot of other people, even some proton basher admitted this.

Certain people might not like or feel sufficient with it and willing to spend thousands $$$$$$ to have “Ah Beng Ah Seng’ whatever, so what! it’s their money!

PERODUA is not owned by TOYOTA. Owns means you have the majority shares in the company.

I dont think you know what are you talking about and i do not think you know what i'm talking about too.

If you do not understand pls refer to what QUEST said. His explaination version is better.
