Id recommend this to anyone with a common rail diesel engines. Apparently this made a wonder of a difference to the drab Skoda Tdi.

Sorry! OT
"Boost Controller"! well do plan one for your Swift? i would really want to see a VDi (infact the 1.3 Multijet)unleashing all its hidden potential and MCL i would really want your pov on the thread i started called TURBO Confusion. Here is the link>>

Keshav, its funny you are saying it sounds too good to be true (coming from someone who always wanted to get more out of an engine and still does). But, people I & you know have done it already. Like you mentioned at 1bar, clutch didn't hold up. But I didn't suggest people to go upto 1bar (and even if they did, I mentioned the cltuch issue in my 1st post on this topic as well).

However at 10psi, there was no issue with the fuel pump. A similar project was done on a Skoda Tdi and it came out with flying colours.

Yes, ripper. Any electronic boost controller will do the work (preferebly a Greddy Profec Bspec II or a blitz). But remember its best done by the professionals.

At 10psi (3psi above OE) I don't think the clutch will last. Maybe not as long as when running on 7psi. Either ways in 35,000 kms on a NA car I have changed 3 clutches. Its more to do with the driving style too. It won't harm if you can find a aftermarket clutch for the engine. Or I wonder if the Sonata's clutch will be a bolt on? I think it should and certainly can hold more torque/power.

Contrary to what most people say, running rich is much safer on the engine than compared to running lean.

installing a new turbo kind of defeats the purpose of using a boost controller doesnt it?

wont a standalone ECU help with new fuelling maps? is that kind of service available? how much would it cost?

Installing a new bigger turbo would mean getting the ECU re-flashed as well. Alternative choice is to go to Hyundai, pick up the turbo off the Sonata Embara and its ECU and fit it on the Elantra. Engine is the same on both cars.

I don't think there are any aftermarket diesel ECU's sold in India. I did hear that RDK was planning something on these lines. Don't know if the plans have materilaized.

In the process of getting one for the swift. Before recommending things to others, I prefer testing them myself on my own car. WIll keep you posted on the details. Just waiting for the car to clock 6k kms.

Besides, I hope people do realize that these are just a few ideas for those who want to go a bit quicker but don't know how to. In the end it all depends on the way one drives or ones willingness to mod.

PS: Sorry for the late reply. Don't have net connectivity. Rarely get online.

thanks for the reply rahul, but i have a few more questions.
with the boost going up, and the engine recieving more oxygen, running lean is a distinct possibility with this mod is'nt it?

also, if the boost is upped, does that mean turbo lag gets worse?

I ask because, the higher the boost , the longer the spool up time right?

or will the turbo kick in at the stock rpm, but give its highest boost later in the rev range than stock?

Are you sure that Embera and Elantra have the same engine, because Sonata is VGT and Elantra is not.
That's true that both of them has 2L engine.

[ballkey]

Gangsta, VGT is Variable Geometry Turbo; which means teh sonata has the same engine( 2 litre) with a bigger, better turbo.
So McL says take the VGT and ECU and put it into the Elantra.

VGT (Variable Geometry Turbo) is a variation of the Turbo than the engine. So, both the engines could be same but I wouldn't know. You could check the Engine codes with Hyundai for both cars & confirm.

[Gangsta]

isnt Sonata Embera VGT is a DOHC Block? Elantra CRDi have a SOHC Block.

[mclaren1885]

Some of us spoke to the Hyundai guys. They said Elantra clutch will be able to hold upto 10-12 psi. Apparently, the car runs with 12psi in some countries and none of the parts have been changed for India alone except turning the boost levels down is the info given by them. This has been confirmed by none other than brraj and his friend satya who called up the Hyundai people. Still too good to be true?

1) Would not like to see any one blowing up their engine on heresay
2) Would do it 1 psi up at a time and do at least 5k km to see if it remains stable before saying it is great
3) Any engine can stand abuse for a short duration but the quality of build will define how it performs on the long run
4) Ancillaries around the engine will also bear the brunt, hence will have to be more careful
5) Which is why I said going up 20 -25 percent on boost would be a safe bet

1) Yes it still is
2) Not too sure if the metallurgy is the same in India as worldwide
3) The Hyundai people can also be a service manager who might not even know enough to quantify that claim

PS: How many of the people who own these cars would even know if a problem occurs on the car till it is too late.

I am not here to dissuade anyone or stop anyone from trying it out all I am saying is there are limits to which stock engines can take abuse so be careful. There is no harm in saying that.

As for me yes I have always gone all the way out on my car but might never do it on another's car ever again as one never knows what might be the outcome. Like they say it is better to be safe than sorry.

[v1p3r]

Quick tech question: how is a diesel pump going to compensate for the 50% extra flow? Do diesels have O2 sensors that detect whether a car is running rich or lean, and compensate accordingly? Or do they run MAF/MAP sensors that have a 50% scaleability built into them?

I can't seem to find any Hyundai Elantra running 50% more power than the Indian version. Google has failed me.

[ram_hyundai]

Oh my,lot of options are jotting up for the elantra.So will this mean a demand for used elantra.Anyways looking forward for a VGT elantra.

AFAIK, the engines on the Elantra are an import and are not made in India unlike those on the Verna. I may be wrong. Maybe Tadu and others will be able to confirm. And I am sure the manufacturers would leave room for that extra bit. According to your theory, running a turbo on a esteem (or any car for that matter) at 7psi on stock internals must be sacrileage as well isn't it? The engines are made in India, and converting a NA car into forced induction is a different ball game alltogether when compared to slightly increasing boost on an already TCed car. Yet most people I see run on stock clutch, internals, fuel pump etc. Do people do this based on hearsay? Or is it just experimenting ones own acquired knowledge and assumptions to see what transpires from it? Or is there a rule book that says one can do all of this on a NA stock engine from the manufacturers themselves?

Bottom line is, I really would not suggest anyone to turn up the boost levels to insane amounts. To neglect people from making this mistake, I am sure a boost controller can be set with a max allowable psi limit as well.

Also I was told that the engines on the Elantra and the Sonata Embara are the same except for the ECU, bigger turbo amongst other things. If that is the case, I am sure it should be able to handle more boost. A stock elantra puts out 112.2 PS and 25 kgm of torque while a Sonata Embara puts out 142 PS & 33 kgm of torque. So almost a 30bhp increase on the same engine should quantify for about 2-3 psi increase (which too would translate in the region of about 20-30bhp?) on the Elantra engine as well IMO.

I came to this conclusion based on these possible facts and not just by mere heresay. I hope you got the answer you were looking for Akshay. Google does not always provide direct results . You need to look it down carefully.

[kpzen]

A stock Elantra CRDi is fast and with petes it becomes insane. Not many cars pull like the Elantra does relentlessly from 0-180kmph.
Top speed of around 210kmph and it redlines in 5th gear and still u guys want some booster etc to experiment with one of best diesel engine ever sold in our country..

Do u guys get airport runways to test your cars or what??

Well if you have worked with the Verna's, Elantra's or for that matter any Engine then great, I haven't (worked on the diesel's of the hyundai range) and I don't have the guts to make recommendations on hearsay. As far as the 7psi theory goes you cant do it even on a stock ecu, you need at least a piggyback as the stock ecu throws a check engine light at 4psi max on most engines.

As far as I know I can give an opinion but cant push it down one's throat so please leave me out and carry on your discussion. Thank you.
