Multiplying that by 3.42 and 4.4 to account for gear multiplication to get torque transmitted to wheels we get about 2400Nm (ignoring transmission losses of course). That means it's making around 160Nm of torque. In first gear at 4000rpm, the engine is making 90ps of power. I can't remember what the exact gear ratios are on the i20 crdi are but i'll take the first and second to be 3.42 and 1.95 and the final drive to be 4.4 (those are from my vista, but they should be fairly accurate for the i20 as it's the rpm drop that's important and, IIRC that's pretty close between these cars) I'll give an example to explain why i think so. But i don't think that would give the best acceleration. I'll agree with you that might be the best way to enjoy a turbodiesel. I agree the best way to enjoy Diesels is to upshift early to keep it in peak torque zone. It's out of peak torque zone but is still in power zone, remember most Diesels make most power upwards of 4k RPM.
I have only two driving modes - minimum throttle mode for the best fe and high rev mode if i'm in a hurry and i spend a fair bit of time in both. Oh, are there any other specific things that i should look out for or need to be replaced more often? I don't consistently high rev the engine though. But now that my car's out of the primary warranty period, i could do that. Wanted to do so earlier but the service station had all sorts of weird issues with me getting my own oil. Call me weird but i absolutely love the roar! I'll change it to synthetic oil when i service my car next. So, if 4900rpm is going to damage my engine, 4500rpm shouldn't be much better right? Or am i missing something here?Ībout the fe - well, if i have to go fast, i should be able to pull all the 70horses that tata claims out of the engine, right?Ībout the noise - the tdi is noisy as it is but it absolutely roars when revved. Pardon my ignorance, but why is it okay to shift at peak power point as long as i'm not redlining it? AFAIK, the only thing that happens at redline is the fuel cut off. Oh, and on my vista tdi, max power is made it 4500rpm and that holds till 4600rpm after which it drops of rapidly towards the 4900rpm redline. Actually i can't even see why manufacturers are going in for these large bore, short stroke high revving engines even when they are catering to non-enthusiasts as that compromises low rpm torque when they know low and mid range rpms are where 90% of cars spend 90% of their time. Revving engine if it's going to blow up if you rev it high. I can't see why a manufacturer would want to design a high So, am i killing my engine? If yes, what would i have to get replaced/fixed/checked up? The red line is at 4800 or 4900 rpm - atleast that's as high as the engine goes in 1st and the parallax error due to the central instrument pod and the tiny tach makes an accurate reading to get.ugh.Īnd if i shift consistently like this, my city fe drops from 14.5 to 11.5! And I've gotten variations in my highway fe from 15 all the way to 21. I hold it a little higher during the 1-2 shift and the 2-3 shift as the ratio drop is so high and then the 3-4 shift at just over 4500 at 100kph. So, if i'm in a hurry, i tend to hold the gear till atleast 4500. This means that upshifting before 4500rpm has no performance benefits as the gear multiplication of torque outweighs any benefits of being near the torque peak of the rpm band (except maybe a little earlier the 4-5th shift - which, being around 140kph, is rather pointless) It makes at 135Nm at 2500rpm and 110.8Nm at 4500rpm (going by manufacturer's values).

In 2016, DES launched Redline Emissions Products to meet the growing needs of the light, medium and heavy-duty emissions industry. DES also began stocking one of the largest replacement OEM filter inventories in North America, and began distributing in both Canada and Australia. In 2014 DES began manufacturing DPF cleaning equipment under the Filtertherm brand. With over 15,000 emission control devices sold or installed by DES since 2006, they quickly became the authority on heavy duty emissions systems on the West Coast.
DES was established to help California businesses get their trucks compliant and meet or exceed the strict CARB and EPA emissions regulations for their vehicles. DES started operations in 2006 as the Emissions Division of parent company North State Truck Equipment, Inc., which has been serving the heavy duty truck market since 1978. Redline Emissions Products, is a brand created by Diesel Emissions Service (DES) to cover the DPF needs in the light, medium and heavy duty diesel market. Redline Emissions DPF Products are built to last and currently offer the longest warranty of any light duty OEM replacement.
