Doesn't seem to bother farmers either!

Farmers use Red diesel iirc

which is just as harmful - better watch that veg you eat  :tongue:

anyway just for those that missed it i started this thread to show what can be acheived with a diesel engine - yes its not cheap but who cares when you got 400lbs ft ripping up the tarmac  :evil:

donations for my hybrid turbo are greatfully received  :smiley:

What's more impressive is that one of those dervs started off as a 115!

Seeing as diesel is banned in most major US cities due to how harmful it is, i cant see it being the future at all. Recent test have shown how seriously ill diesel particulates make you if exposed for too long.

American propaganda so that they can keep their 6.9L V8's because its less harmful than a diesel  :wink:
I often wonder why people never expect sarcastic comments from me - they're the only reason I speak...

I'd love too drive one. To be honest I can't see how a golf is able to put down such a sharp hike in torque. Even with LSD the front end is going to throw a wobbly and you'll have to power on very gently IMO.

Any ideas how much it cost to get those figures?

Is there any way of smoothing out the power delivery with a tuned diesel? the peak figures are very impressive but VERY 'peaky' that is some torque jump. Personally i'd rather have a longer power curve.

Not bad for a whimpy diesel mind.peak figures on the rollers but then actually see how it

I'm hoping R-tech are still going to do a virtual race as they mentioned a while back so we get peak figures on the rollers but then actually see how it works out on the tarmac!

LPG and biodiesel actually, huge amounts of funding have gone into both. Diesels are expensive to make, buy and run unless you do lots of miles a year, even then it takes a while to break even over a petrol (on 99% of cars)

Would rather have a petrol with strong linear power delivery and manageable torque over a more than a distance of 2.5k RPM

hybrid turbo starts at approx £400 providing your own turbo is in good nick.  What most tend to do is buy a 2nd hand unit and get that done so your car isn't off the road for long

obviously need an uprated clutch so budget another £700 or so

not sure how critical a FMIC is so depending on your base model you might want one of them

then you need to get it lived map which is another £400 plus

i'd say about 2.5K in all and you can get it mapped how you want

i'd prefer a much lower peak torque figure but over a wider band  :smiley:

i didn't start this thread as a diesel vs other fuels debate

i started it as to highlight how many people are actually taking an interest and pushing diesel performance

£2.5k? I reckon you could add a few more grand to that TBH. FMIC would be a must IMO. For a start the 150 pd has it so it must be needed higher up the scale, if your compressing alot of air it will get warm, plus the exhaust is cooking it through the turbo!


Are they able to adjust the torque curve through the map rhyso do you know?


I was following fenwicks build for a bit but came over here and started giving you lot grief instead...  :smug:


Certainly as you say, good for pushing the boundaries of diesel tuning. I remeber VW using the mk4 diesel golf in the rally stages, it was a first at the time!

So, even though diesel is for whimps, i'm quite interested in all this!!
