@ ripper

1.Does the pressure drop after the new intercooler cause a drop in performance? Theoretically should right?
Yes it does - by 2 psi
2.when the boost is upped using the electronic wastegate, shouldnt that compensate for the pressure drop?
It attempts to, but has been erratic so far
3. even at stock boost levels, with the new intercooler and boost controller, the engine is going to be fed a larger mass of air than stock right? what happens to the pressure inside the cylinders then? where do we draw the line?
If you keep the boost stock, the pressure inside will be same. The Petes box itself causes the ECU to bump up the boost by 2 PSI. With the boost controller, it increase further more
4. Fuelling- when the boost is upped, the stock ECU tries to compensate by feeding more fuel to bring the AFR closer to normal, isnt that how the fuelling is maintained? or are you guys using the pete's box to dump more fuel?or a combination of the two? anyone planning to use the RD diesel ECU?

Exactly.We need the Pete's to add more fuel than the ECU. The RD ECU does not have maps for Elantra . Yet once it does,then maybe

5.Are you guys monitoring exhaust gas temperatures? how are you doing it?

We have plans to , once we get the equipment

6.The Apexi AVCR boost controller that I think u guys are using, has rpm dependent boost control and gear dependent boost control right? best results would be if that capability is utilised to match fuelling at particular rpm and gear to the boost, is that how you are doing it? if so, how are you getting the info about fuel injected? does the obd scanner give that kind of info?

Same concept, simpler implementation for now, the controller only kicks in above a certain speed and rpm
I know turbodiesels give a lot more freedom with regards to the AFR compared to a petrol, therefore trial and error will work as long as we're cautious, but, would really like to know how the boost controller settings are being fine tuned.

Sorry for all the silly/nosy questions, just trying to plan out mods and I'm pretty ignorant/bookish when it comes to this stuff.

I think the Magnum shares the same block as the elantra and the gearbox and head are different. I am eagerly awaiting for some tests on the elantra with a piggyback for better control on fueling. Lets see how that goes. Right now, those elantras are keeping up with
RS' and I dont see a reason why the owners should be complaining.

The racedynamics piggyback?
Are these cars also running pyrometers to monitor EGTs?
Just the piggy back, or intercooler upgrade+boost controller also?
Are the exhausts stock?

Ya the RD Ecu's. Lets see, Satya willing that is. Where is he when you need him? Exhausts are lacking cat cons.

Quick, before the green brigade gets here, tell me- how easy /difficult was it to get them off? and did it throw a Check engine light? If yes, how did you get rid of that pesky problem?

Super easy. It was a 15 mins job . And no, it didn't throw up the CEL.

Its a never ending list. Cmiuc is planning to upgrade his turbo very soon . For now aftermarket cross drilled, slotted rotors going in on the car.

You guys got me drooling Rahul
BTW,why the changed rotors?Is the power increase so significant?I felt the Elantra already has a superlative braking system,having experienced it many times myself.
Also,more details on the turbo upgrade are in order

The rotors are getting over heated very soon under heavy braking. Thus braking efficiency decreases. So upgrading to better rotors that improve cooling efficiency thus improving braking.

Hmm..Very interesting.What brand are you guys using for the brake upgrade?
And do keep posting on the turbo upgrade regularly mate.A lot of us non-bangy Elantra guys are getting seriously excited here

any of you guys in banglore?? will be in banglore from 29th march to april 10th for a training program.

if possible lets meet up

and ok lets see now. bigger turbo is the way to go. best thing for a diesel engine is a VGT but elantra is a EDC15 unit. whereas the sonata and verna crdi is a EDC16 unit!
so the VGT thing is a no no.
the basic thing with VGT is it eliminates the use of a wastegate! meaning the ECU controls the turbo vanes directly. so using a waste gate controller(a.k.a boost controller - a basic wastegate signal emulator which gives a custom signal to wastegate hence causing boost increase!)
there is a basic thing with bigger turbos. Turbo LAG will be an issue. the best way to eliminate it is to use a two- stage turbo.

and the best thing with the Elantra is has a TCS sytem hence transferring the power onto the road is not much of a problem!

the best thing to do would be to get a smaller turbo and try to implement a two stage turbo which will mean no turbo lag at all. ( this will be complicated but not impossible!!)
otherwise bigger turbo all the way.

even a race-chip tuning box based out of stutgart Germany will give the elantra some 32kgm torque and 144ps power isnt that enough??

cheers

Which box are you referring to Sameel?I found several such boxes on the net,the P-tronic claims 151 bhp with almost 30 kgm of torque.Even our good 'ol Pete's gives us 130 bhp with almost 31 kgm torque with an additional 10 bhp or so with the extra settings.
