My German Beauty - Pearl Black Polo TDI

[Sandykudva]

@ R-Owl: I think in the diesels it is not the horses which make the difference but it is the Torque that makes the biggest difference now i am driving the Polo every day to work and i just love the way the car pulls after 2300 rpm the 180 Nm torque is really felt there. Only wished if it was available anywhere between 1750-2000 rpm. I have driven the Multijets in a swift and a Dzire the torque starts pouring in at 2000 rpm but the range is very short the car gets exhausted around 3800 rpm after that it just feels like you are straining on the engine but in the Polo the mid range is very punch the power is delivered very nicely up to 4200-4300 rpm and even after that you can rev it freely till 5000 rpm which the car is happy to do and does not feel that strained compared to what the multijets and the other Crdi's i have driven feel. The multijets of the swift and the Tdi of the polo give the same feel on the Turbo spool but in this competition i feel I 20 is the winner but again it has bigger Numbers. I have one friend who has worked on the 1.9 Tdi Octavia and is pretty happy with it. Will have a word with him ans see if any thing is available for the Polo. I Have just purchased the car and its in pure stock form its the highline version so it has everything but will do it up step by step with time and the Remap is last on the list.
So by the time i want to remap it the Remap should be cracked and mostly u and vipin will have done it so can have personal experiences for that. If not there is always the GT available.

Are you rev'ing the car at 4200-4300 rpm ? . I touch max till 3.5 k , how do you feel the engine sound at 4000 rpm range?

 

[shij2013]

Yes, the turbo lag reduces to an extent after the remap. IMO power increase in a turbo diesel engine is more compared a NA petrol one, after the remap. I could be wrong though. After remap, Vento TDI (1.6. Stock power is around 105 hp) puts out close to 140 hp where as the Polo 1.6 (stock is 105 hp) produces around 117 hp. A turbo petrol is different scene all together. Pete's has tuned a Skoda Octavia VRS which produces 370 horses!



True. TBs are cheaper. But in Polos case, I don't think they are that effective as it's only 3 cylinder. Friend had a Spider TB in his Polo and he wasn't happy with the output.

BTW, your custom exhaust is giving any additional power ?

@ shij2013 : Yes have revved her couple of times till the redline or 5000 RPM . To be frank the Sound is harsh but it somewhat the car does not feel strained the same with a multijets and crdi's that i have driven sound harsh but also strained, Infact the polo freely touches the red line whereas the multijets and crdi's dont ( Again this is on my observation and driving). I also have an innova and it hates to be revved forget redlining it. About noise the diesels do make noise for some it is harsh for some it is noise but i love the noise of the diesel with slight noise of the turbo spool. About The exhaust which R-Owl has done is just an end can so it sounds really awesome for an diesel but i doubt any improvement in power. If you really want some improvement you will have to go for the FFE system.

Noise is something which I don't like in polo, but only when it revs harder (mainly when you take reverse or over a slop or a Hill station drive). Hill station drives are irritating for me even with just two people in it
But on highway cruise polo is absolutely a gem

Def, it's the torque. But no matter what one does, diesel cars won't free rev all the way till redline delivering power. The turbo cuts off at around 4k rpm I guess. Even I've taken the car all the way up to the redline couple of times. IMO it's not worth redlining. Planning to go for BMC replacement filters if they're available. Do you think it'll make any difference?

That's a sexy looking polo and a nice Thread up there

Keep making it more sexier

By the way any mods on the engine ? and any ICE setup's ?

Thanks mate. No engine mods. Waiting for the remap. As for the ICE setup, stock HU with JL Audio speakers.

BTW, your custom exhaust is giving any additional power ?

I guess not.

 

[R-Owl]

BTW has anyone tried the top yet? I could only take it up to 155 km/h. Won't go after that. But people have claimed that their Polo TDIs have touched 180!

 

[type-r]

i have personally seen a video of my friend driving his polo 1.2 tdi at 160+!

What change this air filter brings up ?
I am curious to know, changing to high performance air filter adds more power and will it give that bassy exhaust sound ?

 

[Sandykudva]

@ R-Owl:- I agree with you the turbo cuts in around 4200 RPM and yes diesels aint meant for redlining all i was saying is that compared to other diesels that i have driven on long term the Polo somewhat doesnt feel strained.About the Performance filters i am not sure but on what i have read and the very little knowledge i have about it is that the filters wont make that much of a difference as the power generation of diesel is majorly due to the diesel flow and very little part played by the air where as in a petrol it is completely dependent on the the air pressures and the petrol flow hence they make a huge difference on the petrol cars.
About topping the car yes have had the opportunity and as the company has claimed 165 . I have managed a speed with full pedal down the rpm meter at around 4300 and the speedometer needle very close to 170 km/hr. You do anything after this the car aint going above that. i had a pretty empty stretch after that but still it remained constant near 170 but yes rock steady. One thing is there, i have driven cars prior upto this speed and even above but this one takes a lot of time to reach that.
But really i do not like to speed the car it is very dangerous on our roads here in india and the road conditions also not good as one small pointed stone can be fatal and the most important the average of the car. Its a safe bet to cruise around 90-100. Once in a while is ok.

 

[R-Owl]

Don't know why mine doesn't go beyond 155. I'll try it again when I get a chance to.

And another issue, has anyone experienced serious knocking while engine braking in the 2nd gear or de-clutching? Sometimes, I hear 'thud' sounds while doing so.

 

[VipinLJ]

I've touched 160 kmph on the speedo a couple of times on my Velankanni trip. It took a while to reach there and I'm sure it could go more but the roads had unpredictable dips in it so didn't have the guts to do it again.

Vipin

My car too crossed 160kmph. It was somewhere between 160-165kmph. There was a slight slope, so the car marched ahead easily till 160kmph. Could have gone more, but had to slow down since the roads weren't well known.

@ R-Owl & VipinLJ : I had a word with my friend who owns a Skoda Octavia TDi Remapped. I even got an opportunity to drive his car and its mind blowing. The specs after the remap are 110bhp and 260 or 270 Nm torque. As i have earlier owned an Octavia i am completely aware of the difference in the power output. Now i did not have the opportunity to drive the car long but just about 3-4 kms so cant give complete analysis of the remap. but according to him he did it 1 and half years back with no issues till now and no smoking problems also. The average however has dropped slightly due to the driving manner change because of available torque. Of course on highways it returns the same to him around 23-24 km/ltr.
Now i had an word with the guy who remapped his ride and according to him are the following points.

1. The car can be remapped but no one has ever tried it yet from him so he is not sure about the long term results.
2. Power and Torque both can be increased upto an extent.
3. Performance will increase of the car which will improve the acceleration and the top speed.
4. Average of the car is completely dependent on the nature of driving so it may be more for some and less for others.
5. Now the most important thing which i asked him was can i reduce the lag of the car. He said that the turbo will activate at the same RPM that it is doing at present i.e for a Polo is around 2300 RPM this is because of the turbo setup and nothing can be done unless you change the turbo. But yes the time taken to reach 2300 RPM can be reduced a little bit with the remaps.But again upto a certain extent.
6. The biggest problem with the remaps is that due to the increase in power and torque it is very addictive for people to drive it in a enthusiastic manner which does reduce the life of the Turbo.
7. He also told me that most of the people doing the remaps are people who love to drive enthusiastically and who often will not keep cars for more than 2 years so there is no complete analysis or reports are available on the performance on long terms.
8. Also another big problem with remap is that in case the car goes for a remap to the company for some issue in which it has to be scanned. The company can map your car back to stock. So all that you spent might just go to waste.
9. Final note of advise as he is a close pal of mine said do not go to tune your cars specially if they are your everyday rides as the real problems are only known by people doing them. also he told me a biggest no to the TB as they will cause smoking after a desired period.

Now i have a very small amount of knowledge in this field but this is the outcome of the discussion with him. Do not know how much of it is valid and how much is just theories.
