To TC or SC is better?
-
Dear All,
Can find out from ppl who did the a/b mentioned care to offer some advice?
I'm thinkin of TC or SC my IS200 with an ECU Upgarde(Piggyback).
Any idea the Cost and HP/NM gains? Which are the difference btween them?
Tks

hey bro .. i think there is no point TC the car and placing a Turbo in it because it is Auto and it dun usually works well with Auto trans .. my advice is to SC it .. and go thru the relevant authorities with the SC-ing ..
-
TC on auto not recommended? Hmm..... But i believe TC is cheaper & more horses gain? Quite a no of TC cars on Auto?
Tks. -
i think i saw an article on a mag (either hotstuff or wheels) featuring a IS200 with turbo and is approve by LTA ... maybe you care to check it out ...Originally posted by eric3417:TC on auto not recommended? Hmm..... But i believe TC is cheaper & more horses gain? Quite a no of TC cars on Auto?
Tks.
will check out which issue then let you know

SC shud be better... turbo very ma fan... SC cheaper sum more.
-
for me lah...horsepower wise, TC better...but got pros and cons for both...actually TC very hard maintainence. Nothing wrong with auto having a turbo. SC to me in the long run its cheaper, and ur petrol u can save more with sc...but not as much horsepower than a TC...the top end is better...
TC u can get the adrenaline.....hahaha...but maintainence quite high... -
does sc hav the pssst sound???
or only tc have???

Can if u can prove to LTA tat the improvement to the car is within the limits of the car chassis and will not be harmful towards the other cars users if it is put on road....Originally posted by nick34:i think i saw an article on a mag (either hotstuff or wheels) featuring a IS200 with turbo and is approve by LTA ... maybe you care to check it out ...

Orh, means TC time won't break into pieces?Originally posted by Praetorian111:Can if u can prove to LTA tat the improvement to the car is within the limits of the car chassis and will not be harmful towards the other cars users if it is put on road....

Pros and Cons of supercharging
Before turbocharging arrived in the 60s, supercharging used to dominate the forced induction world. Supercharging, also called mechanical charging, appeared in around early 20s in Grand Prix racing cars in order to increase power. Since the compressor is driven directly by the engine crankshaft, it has the advantage of instant response (no lag). But the charger itself is rather heavy and energy inefficient, thus cannot produce as much power as turbocharger. Especially at high rev, it generates a lot of friction thus energy loss and prevent the engine from revving high.
And from my fave source of info..
A typical supercharger transforms the engine very much - very torquey at low and mid range rpm, but red line and peak power appear much earlier. That means the engine becomes lazy to rev (and to thrill you), but at any time you have a lot of torque to access, without needing to change gears frequently. For these reasons, supercharging is quite well suited to nowadays heavy sedans, espeically those mated with automatic transmission. On the other hand, sports cars rarely use it.
The noise, friction and vibration generated by supercharger are the main reasons prevent it from using in highly refined luxurious cars. Although Mercedes-Benz has introduced a couple of supercharged four into the C-class, they are regarded as too unrefined compare with the V6 serving other versions.
The introduction of light-pressure turbochargers also threathen the survival of supercharger. Volkswagen group, for example, dropped its long-standing G-supercharger and chose light-pressure turbo. Now supercharger is completely disappeared in budget cars, leaving just a few GT or sports sedans which pursue high torque without much additional to employ it. General Motors is perhaps the only real supporter to supercharger. It offers a 3.8-litre supercharged V6 for most of its budget mid to full-size sedans.

From what I heard, Mercs are now switching to turbochargers (the new A200 will use it and their new SL65 flagship is also turbocharged). The SL65 is faster than the SC SL55 -
Tks Bro. Ur explanation is indeed detail.
Dun think i will sacrifise My ride for the Noise & Vibrations. (SC)
Like that like drive lorry ah....
Any good mods to increase HP & Torque for my Ride?
ECU Upgrade good enuff? Advises anyone?
Coz my ride could make do with say extra 20hp/50nm Torque.
Tks -
the psst sound only applied to turbochargers (TC)...the psst is caused by the Blowoff valve.not the turbo itself...to prevent the turbo ballbearing to run backwards.Originally posted by D16Z6:does sc hav the pssst sound???

seems like u already intend to TC ur lexus b4 u post tis thread...Originally posted by eric3417:Tks Bro. Ur explanation is indeed detail.

Every chasis shape is calculate to within g-force and watever... and of course the engine and various major components is being calculated to determine whether after turbo charging, it will cause any instability to occur...Originally posted by Subbx:Orh, means TC time won't break into pieces?

Any ah beng ah seng can do the work of putting a turbo into his car... but of course, the aftermath is tat the ah beng got an engine blown or gear box blown.... Oh Oh I talk too much shld let 'professional' to do the talking... (mhhhh nv see him ard this days) -
that's why the younger generation choose not to declare...Originally posted by nick34:and insurance will kill you
cos only the 'young at heart' can afford the insurance. i think it will be base on the same charges as with the ones of the same C.C which is turbo charged.... Mhhh this one have to confirm with an insurance company... -
the insurance charges will increase when you add a turbo to your non turbo carOriginally posted by Praetorian111:that's why the younger generation choose not to declare...

To be honest, you are better off changing car than trying to manouvre yrself through all the redtape.
In your class of cars, the other strong contenders would be
a. Volvo S40 T5
b. Legacy GT
c. C200 Kompressor
d. A4 1.8T (or wait for the 2.0FSI Turbo)
All of these would have lots more torque delivery at lower rpms than your current ride. -
Personally test drove the Legacy GT. Love every second of it!
Maybe for another 6mths or a Yr then change to Legacy.
But is the Legacy very Thirty? -
thats definitely...but might not be as expensive as hisOriginally posted by nick34:the insurance charges will increase when you add a turbo to your non turbo car

Generally, most cars with forced induction will be less fuel economical than an NA one, but a lot also depends on yr driving patterns.Originally posted by eric3417:Personally test drove the Legacy GT. Love every second of it!

If you are less heavy footed, the cars will not consume as much petrol.
The problem is when you first move to a TC car, the addiction to the power delivery can be err devastating to your consumption.
