Thats why i thought it was the same since i read it having the same bore and stroke too.
But in any case, i think most of the mahindra turbo motors don't necessarily use turbos to develop loads of power, but rather just to clean up emissions. Why, look at the DI turbo, where i think the sole objective of using the turbo was to clean up emissions. An rise in torque of just 1.5kgm in a 2.5liter motor after using a Turbo sounds absurd. Although i beleive that as far as the Commercial usage was concerned, it might as well be for good, since the basic strength for the Di as far as load hauling is concerned lies at bucket-loads of torque available right at Idle. Even with a turbo, there would not be as huge a torque increase at Idle, but yes, surely as the Turbo boost increases, so will the torque resulting in a very steep upward graph till the maximum torque level would be reached at about 1600-2000 rpm.
Also, since most drivers in India are not Turbo educated, developing huge amounts of power relaying mostly on the turbo, like modern motors as the detroit diesel in the hyundai accent does, will kill that same strength factor of the Di that makes it so popular with the hauling crowd. Not only will Tubro-lag be the factor, but since turbo's are fragile, abuseing it a little, like we all do(not giving it enough time to run, and oil-up after starting, or before shutting down, etc). Yes, i know there are other engines in the commercial league that do very well despite relaying on the Turbos to a great extent, one of the best being my favourite, cummins, but then these motors were designed keeping the Turbo in mind, whereas the Di is basically an ages old motor that mahindra decided to keep developing, "why fix something that ain't broke", havn't we all heard this phrase way too many times. Don't get me wrong, the Di is one of my favourite motors, and if these guys still come up with a 4x4 Bolero powered by the Di, i'll be the first one to get it, but i think Mahindra did us a whole lot of injustice by ponking in the same Commercial motor in there. Atleast they should have re-enforced the motor, higher boost, more fuel, used an inter-cooler(not for more power, but the cooler air provided by it will ensure that even in extreme offroading sessions, it would not overheat as fast as the other motors), and yes, alteast should have re-designed oiling routes of the motor, especially the lower end, and placed a different oil pump with an oil-cooler so that the sump would not hang as low as it does now( doest the Di squirt oil under the pistons like most of these hardcore besigned for reliability motor do to keep things cool). I hate this lethargic attitude of mahindra of not packagsing the right stuff for the right vehicle, and especially the "Take it or leave it" policy, coz we have basically no choice regarding the 4x4 bolero. Since the buyers are few and far inbetween, and they already charge a premium for what they deleiver, they could have made a few motor choices available to the customer, who would'nt mind spending some more given the choice. The same goes for those so-called limited edition or the custom designs. What charge a lot of "cutting it up", and everything else is that same(i wonder if those models, like the stinger, even come with a 4 wheel drive)end of also means lesser stress on the motor,
As for the the new Bolero crdi, if its what we think it is, then it really is a pity, since not only did the XD3TE( the turbo version of the peugeot Xd3p in the 80's) produces 24kgm torque and 102hp, but also was more fuel effecient, and i have no reason to doubt its emissions too. If thats the truth, then mahindra is just trying to cheat customers by charging a premium for quoting their super CRDE tech, but also (this point is very important if it really is the same motor) because they did not try to extract atleast a reasonable amount of power that the common-rails are famous for. I mean common, 2.5 liter motor with a common rail can easily develop 12kgm/liter, look at the 2.2 liter for god's sake, it still produced more power, though the Variable turbine blade angles also plays an important part. Even without it, you could expect it to produce an justified 10kgm/liter.
Even if its not the same motor, still it does'nt do it any justice, since its still way too underpowered for what it could develop. What they are trying to say is, "the new motor is better, it has the common rail Tech, but we never bothered to put in the lasted turbo to complete the paskage, we did'nt have time to do that since we like to sleep when its working time, so just this much will do , and for which we will make you pay through your noses, especially your hard-earned money. Although i have to admit its still is not as powerful as the older turbo motor that its based on, or for that matter any older motor with the same displacement, it does not give you more fuel economy, and i'am not sure if it does much for emissions. Besides it good for us since what we learnt from the bombay floods is that you can make alot of money by developing motors based on computers and external sensors. But frankly, our customers, do you really bother with this CDRE tech not producing more power, since we still ain't going to change anything on the vehicle its meant for. I mean, you still would not get the nominal amounts of creature comforts like a goog set of seats, especially the rear ones, and no folding seats either, no power rear views, no rear defroster, not evne a simple defogger blower for the front windscreen, let alone the other A/C funtions, besides the other things, But not everything is the same, after a lot of research and the millions in currency involved, we managed to develop the best internal fuel lid opener, and we would do you a huge favour by installing it in the new bolero, though we will make sure you would have tp pay lots for this latest tech knob. Heights man, Wake up ,we Indian customers.
Another reason for not developing more powerif its the same based on the Indian non-turbo peugeot is that they never bothered to strengthen the original block. If thats true, then you know whom to called a crooked thief. |
