Turbocharge Supercharge (TSI)

[Vega]

You forgotten the VW Scirocco.

Now the "IN" thing is Scirocco, no longer Golf. Haaaaa...

Yap. i am waiting for my Roc this coming Oct.

[Wt_know]

haha ... this one no need to say la. what about V6

but, IL-6 or V6 will be much more expensive already so you pay what you get

 

If 2.5L NA is IL-6, i will definitely take it.

the TSI is a crap engine. When the supercharger shuts off and the turbo kicks in there is a slight 'jerk to the drivetrain. If you're in the middle of a somewhat fast corner; hit a bump and this 'jerk' happens you can say hello to the tree.

 

If the engine is purely supercharged or turbocharged there is no such event. It rises smoothly, though it may not be linearly. More importantly there is no sudden 'jerk' that is both uncomfortable and potentially dangerous.

 

There is a reason why GTI is the top of the range. It is better engineered, not a piece of fancy idea with the low-end high-end power theories cobbled together

thanks for your input.

 

between TC & SC, i personally feel SC is more suitable for street driving

Perhaps some get the TSI because it's only 1.4L and roadtax will be lesser.

Best of all, with such a small engine, you can have a decent pick up, so why not?

 

Ultimately, I still believe that TSI is a good technology.

Best to back my theory is that, the new VW Scirocco is still using it.

See this link: http://www.sgcarmart.com/new_cars/newcars_...p?CarCode=10725

 

VW comes DSG gearbox technology which is the shortest time to change to next gear till date.

Even Ferrari cannot compete. Even Audi cars are using it.

 

So, TSI from VW, should be a good design as a whole.

rally aside, is turbocharged and supercharged car "suitable" for street-driving ?

i always assume a car maker will either choose turbocharged (use exhaust to force air) or supercharged (use a charger to force air)

i have never thought of both force induction techniques are installed in a car. it must be damn complex to manage 2 boost and timing.

 

I suggest you do abit of reading up in VW's website on their SC + TC combo.

Very informative, very effective application of technology in a small block.

Add the fact that this is a mass-produced car, not a purpose-built track/rally car, it start to look really impressive.

IMHO, i feel that in consideration for cost as well as FC, perhaps small displacement engines coupled with turbo at low boost will be beneficial. Small turbos that spool at low revs with minimal lag is very much preferred by me as opposed to having a supercharger because the engine complexity is greater with a supercharger.

 

Nowadays NA cars are able to achieve relatively high torque figures at low revs but having a turbocharger will allow for more stallions are low revs and hopefully ease pressure on the gas pedal particularly in the 50km/h to 70km/h range. Good for city driving.

 

Maybe SC+TC hasn't become cheap enough for mass market yet.

V6 is no no to me as it is more complicated than IL-6. Everything has to be duplicated on both banks & counterbalancing shaft is needed to mitigate end to end vibration. In the end, IL-6 can produce more juice than V6 as it lost less pwr along the way.

In term of cost & FC, TDI is the best. It is torquey enuf for city drive & low FC. However, our road tax system resulted in astronomical cost for TDI.

TSI got me v excited when i first heard of it, and even more excited whn i knew abt DSG. Very impressed with VW that till now, it remained my no.1 car choice, esp for my next car.

 

Tho its gd, i feel tat complications may arise and whn it does, repair bills will hit the roof. Thus, the 1.4t 122hp is gd for me, thn i go aftermarket tuned it to TSI spec. Abit more turbo lag thn the TSI but cheaper, more fun to drive(lighter weight) and lesser insurance too.

I went for a test drive when vw launch the 122bhp..Very impressive i would say for a 1.4..The DSG is ..BUT after i test drove the 160 twin charger..haha i have been thinking day and nite...

I now waiting for the Polo to reach our shores with the 1.2t (heard news that they may only bring the 1.4NA w 7sp DSG ) end of this year.

 

If AD dont bring in the 1.2t, i will go take a look at PI le. Perhaps they may even bring in the 1.2t w 6sp manual. Hahaz! Price, lets say 58k. Oh my, i Cant WAIT!!!

[Peaceracer]

AHHHHH.....

I doubt the 1.2T can be that price. The 1.4 will already be around 60K at least, so the 1.2 might be mid-60s at the very least. Anyway I have read that production of the 1.2T starts later, which is why it will not be offered here at first. Maybe it will come later.

Be careful, the new 7-speed DSG is designed for torque output up to 250Nm. Better not exceed that, or you may be risking higher wear and tear.

Yaya, Agreed. Thats y i hope that it comes with the 6sp Manual to bring the price down to abt 58k.

 

Oic, okok. Thn i shall be patient....

I am not sure, but i suspect that it could be a marketing technique. Cos Audi's Q5 with a 350Nm 2.0 engine uses a 7sp DSG and also the S4 3.0 SC with 440 Nm using the 7sp DSG. I think they should be using the same gearbox as VW's right? I have a feeling they place that 250Nm limit as the GTI with its 6sp DSG would be threatened is the Golf GT was allowed to be tuned to 200hp, 300Nm which APR is able to.

 

Dont knw wat u guys think...

No, the 7-speed DSG used by Audi in the Q5 / S4 / etc is a completely different unit designed for longitudinal applications. The VW 7-speed DSG is a lightweight new design for transverse engined cars.
