Diesel Power Potential

So I was thinking lately...

If diesel engines are built to handle extreme amounts of pressure, and thrive on forced induction, why don't we see more modded diesels?

Some diesel engines are designed to be able to run at very high boost levels, much higher than stock, without having to open the engine.

Sure, they do not have the ability to produce power at high engine speeds, but a strong mid range performance can also be a lot of fun, and IMO BMW's 6 cylinder diesels sound fantastic. It's torque that wins in the real world, and in many cases races. Diesel is much cheaper than petrol to buy and many modern diesel engines return better fuel consumption than their petrol/turbo counterparts.

Some call it the fuel of satan :mmm: but it does make an awful lot of sense, both from a fuel efficiency and bang-for-buck performance perspective.

As much as I envy the fuel economy and power of those diesels, I would rather be with my NA 6 cylinder petrol. It sounds beter and I don't have to ...oh crap where is my boost :rollsmile:

But agree with you, what is the limits these things can go prior to doing serious modding like changing engine parts etc.

Lol listen to and drive Karsh's , Rayzors, Andy1Gps or a couple of other modded diesels on the forum. Dp and exhaust and they sound like the petrol variant.

Those cars vary in power from 190wkw to around 240ish wkw and 600nm of torque this with a combination of sw, dp, exhaust and upgraded intercooler. Theres still more room with water meth, 535d injectors and hybrid turbo. And even when modded to hell they still lighter on fuel than the petrol counterpart

Turbos start to boost at 2000rpm with the diesels so lag is minimal.

But a high revving N/A 6 cylinder has its place aswell and has a special feel to it.:rollsmile:

We do indeed see plenty modded diesels. I think there are fewer unmodded diesels on this forum than modded, especially the 3.0d's.

I disagree with this slightly as it depends on what you mean by high speeds.

My 530d runs on low revs, and at around 160kph on a level road I'm only revving at around 2500rpm. I still have boost range left, and if I put my foot down she'll drop down to third and lunge forward without disappointment.

Perhaps not made for 250kph+, but then again not many BMW's have their limiters removed.

Careful :mmm:
Diesel prices are not regulated...



But overall I agree with you. DIESEL POWER FTW :thumbsup:

Lol na don't get me wrong the 330i is an awesome car and comes together nicely! Modded they really fun aswell but it all depends what you want from a car? Power or Revs? Or both has the new boosted cars allow :rollsmile:

were arnt in merica

and diesels suffer from from clutches and boxes, the new f30 8speed will be potent tuning platform

but if i could i would drive a 6.3 cummings(terrible minds) hx52 turbo

and i agree with the above.. who has a stock diesel these days anyway :rollsmile:

Love love love my diesel, my first diesel ever and I will be hard pressed to go back to petrol for a auto daily.

But when I gooi around with the Z4.. nothing can beat that 6 pod..

Both therefore has their advantages.

Okay, but where are the crazy big turbo projects?

Even modern turbo diesels run out of breath after 4500-5000rpm. Some auto gearboxes' software aren't suited to this, and as a result kick down too much which place them at the upper reach of the torque band.

You, sir have the right recipe there. Diesel for the daily commute and long distance touring, straight six petrol for fun over the weekends :clapper:

My first diesel. Always been a fan of high revving na motors.

My first bmw and I am loving my tractor.

So many people see the d at the end of the 330 and make the assumption that it is diesel and therefor slow.

To the poster that mentioned that the 8 speed box has opened the potential of the 30d motor, I agree with you 100%. The car is always in the right gear

To the poster that mentioned that the turbo starts boosting at 2000rpm in a diesel, the 330d doesn't seem to suffer from lag. Just ask the rear wheels.

I have a modded 320d as a daily and a screaming NA car for weekends. I'll sell my NA car before my diesel
