Calling out to DTUK CRD-T users.

Cannot la WZ, onli can afford one box at a time. Unless someone sponsor his DTUK for dyno comparison...


Aku ade bmw lori ko ade?

Please be the first PPK + DTUK combo user lah.

Hello,

I bought DTUK CRD-T a few days ago, installed it in my E90 320d Manual PPK and now I'm in the testing period......I will do a rolling road dyno in a few days and see the actual results....

Hello guys! I bought my DTUK few months back. But only recently (before CNY) I decided to install it on my F30 320d +PPK.
I'd like to go do a Dyno to see how it really performs. Any dyno place anyone could recommend?

As for how the PPK + DTUK feels...I definitely experience a slightly better reduction in turbo lag, but there still is. Not much difference in turbo lag if you press your pedal from 0% to 100%.

The engine somehow feels to be running slightly smoother for me. I usually feel some vibration from 1500rpm - 2000rpm mark during slow pick up. But this vibration was reduced.

I haven't really got the chance to push the engine to max that much. But the few times I tried, I feel that torque delivery seems to widen a bit more. Specially when its at 3000-4000rpm mark. Though Engine still feels quite lacking in power at most revs above 4000rpm.

As for top speed...I usually use NKVE, and it's not easy for me to hit top speed. Only done it once before when it's like 3am and lesser cars on highway. So far I've only hit highest 220km/h.
But I can feel that my pickup from 120km/h - 200km/h is much faster than before. I haven't really got the means to time it! haha!

Lastly for 0-100km/h...I feel there is a definite improvement, but I'm not sure by how much exactly. Because my butt dyno tells me that my acceleration feels very different from previous with PPK only.

Owh, and I'm using Map 4 for this. Andrew from DTUK told me this map was specifically for 320d + PPK. I haven't tried other maps yet.

For black smoke...I'm not quite sure really. I think it might be better. I can't see it when I'm driving. But I realise I'm collecting less black soot on my rear end.

That's all folks! Do let me know where is good to do a Dyno test! Thanks!

If you go to Sunway there are a few places you can Dyno your car at, Vision or GT Auto which I think the other F30 boys also dyno their cars.

 

[SilverBullet]

if I remembered correctly, our club used to do a group dyno session at GT Auto, Sunway..look for a nice chap called Thomas

do share with us the results later cheers

guys

any update ?

PPK + DTUK?

 

[Mavik]

guys

any update ?

PPK + DTUK?

Dyno figures were 206ps and 460Nm (DTUK +2 setting on Map 4)

Stock - 171ps 370Nm
PPK alone - 185ps 422Nm
DTUK alone - 198ps 432Nm

 

[Gunso7889]

I want a DTUK too...
Where can I buy now?

 

[Mafulat]

check in with Farul 012 312 6545. get the pedalbox too.

Result from F30 grp dyno at GT Auto earlier this year:

F30 320d DTUK setting +3: 210whp 477Nm

Woah that's awesome. Is +3 reliable? I know someone had issues with +2 on the track as it sends the engine to limp mode.

 

[_M_]

Mavik.. not so reliable if pushed really hard. Need to match it with bigger air cooler?

 

[joonsuan]

I think if you don't push hard is fine, like regular driving on the roads, but when pushing on the track, heat becomes an issue. The higher the setting means pushing the car harder, more heat. After a while, limp mode comes in to protect the engine.

M, more than just bigger intercooler, also need better engine cooling... Heat is the #1 enemy.

Changing to bigger intercooler on my 335i does help my engine oil temp to run cooler (reduced by ~10C), even with stock oil cooler

Bro, the intercooler does not reduce your engine oil temp, it only cools the charged air going into the engine so that it can be compressed further for better ignition and more power

Yes bro I know exactly theoretically what an intercooler does..but just sharing practical info from my real life experience..at that time onwards there were no other changes to the car that could have contributed to the lower oil temp..anyways upgrading the oil cooler would be the best option..

My understanding is, intercooled air going into the engine also reduces the resulting the exhaust gas temp..the exhaust gases passing through the turbine section of the turbocharger are extremely hot under extreme driving conditions..this heat passes through the turbocharger unit and contributes to the heating of the air being compressed in the compressor section of the turbo..if left uncooled, this hot air enters the engine, further increasing internal temperatures..this leads to a build-up of heat that will eventually stabilise, but this may be at temperatures in excess of the engine's design limits - 'hot spots' at the piston crown or exhaust valve can cause warping or cracking of these components..high air charge temperatures will also increase the possibility of pre-ignition or detonation..detonation causes damaging pressure spikes in the engine's cylinders, which can quickly damage an engine..these effects are especially found in modified or tuned engines running at very high specific power outputs..an efficient intercooler removes heat from the air in the induction system, preventing the cyclic heat build-up via the turbocharger, allowing higher power outputs to be achieved without damage..also our turbochargers are oil-cooled, hence excessive heat from exhaust gas may be exchanged to the oil while cooling the turbochargers and then going back into the engine causing higher engine temps..anyways just a thought

Yeah but all due respect, all of that statements doesn't seem to explain a cooler engine at all.

Your statement

"intercooled air going into the engine also reduces the resulting the exhaust gas temp..the exhaust gases passing through the turbine section of the turbocharger are extremely hot under extreme driving conditions..this heat passes through the turbocharger unit and contributes to the heating of the air being compressed in the compressor section of the turbo..if left uncooled, this hot air enters the engine, further increasing internal temperatures..this leads to a build-up of heat that will eventually stabilise, but this may be at temperatures in excess of the engine's design limits - 'hot spots' at the piston crown or exhaust valve can cause warping or cracking of these components"

As you have mentioned yes, the exahust gas comes out from the turbo but that is then cooled by the intercooler. The better the efficiency of the intercooler (large surface area, core efficiency etc..etc.. the maths can be calculated here h

And also where you copied the statement above, look at your last sentence. Doesn't it support the statement that it does cause engine temps to be higher and not lower?

while cooling the turbochargers and then going back into the engine causing higher engine temps

I mean no disrespect but this was what I was taught by tuners as well as from mechanics. I am really not a mechanical nor technical person hence a lot of ppl call me the term internet noobie because I just learn from what I read on the internet. I am ready to be corrected as I believe this is a learning process for me.

Nice diagram bro! Btw, the diagram is a bit unclear on what drives the turbo (turbine)? The hot exhaust gas. The turbine is connected to the compressor via a shaft, when the turbine spins, the compressor then spins and compresses the air from the intake. (I stand corrected, but hopefully this is still valid from what I've learned in my final year 10+ years ago)



Sorry my last sentence was meant to say:

Cooler exhaust gas ---> Less heat transferred to the turbocharger while spinning the turbine ---> Less heat transferred to the oil while cooling the turbos ---> Lower oil temp

Anyway heat is very subjective, the exhaust gases passing through the turbine section of the turbocharger can vary from 450°C to as high as 1000°C in extreme conditions. So imagine that under our closed hood, confined space and hot weather. How it will affect the overall engine temp without additional cooling. Again I'm just saying I got better oil temps after upgrading to a huge intercooler. That's all, don't have to agree with me or we can agree to disagree! Cheers and enjoy your D's. Peace out, this is no place for a petrolhead like me

With this explain why you are having a 500hp monster [emoji13][emoji13][emoji13]
