Diesel Technology has obviously advanced massively over the last 10 years.

But virtually all are turbo charged.

Is it not possible to extract decent performance from a modern N/A diesel engine?

Evidently not otherwise they would all be doing it no?

Even if it was DPF's/EGR's etc (EOBD) would strangle performance...diesels need turbos & personally I like the rush:slayer:

I've pondered this question as well, what sort of power would they have without the turbo?

I once drove a none turbo diesel 306, it was horrible- wasnt even that economical either!

same here with a 307 (I think?) estate, was in great condition etc but when I drove it I actually laughed at its lack of power (foot to floor all the time) I walked away.

im used to driving a sprinter without a turbo and my dads cabstar.... both flatbeds...

get into the transit tdci or merc vito van and its completry different...

i would go as fas saying my dads vito van was near enough as quick as my stilo empty

My 56 Doblo is a 1.9 Diesel (120) Multijet 7 seater and that doesnt have a turbo - it could do with one I am sure. Even with the 1.9 L engine it does struggle or maybe I am just to light on the gas. If the 1.9L is like this, what is the 1.3 L version like ? I wish I had gone for the petrol version now but always felt the diesel would be more economical. Apparently not the case and its quite expensive to service. Yesterdays oil + filter change came to £ 101 !!!

1.9Mjet does have a turbo

correct matt I think he is refering to the 1.9DS as the 1.9MJ is actually quite rapid. The 1.3MJ is quicker than the 1.9DS I reckon...there is no 1.3 non-turbo version but a 1.2 & 1.4 petrol.

just been behind an SDi golf.... completely forgot got about that dogger of an engine- is it turbo charged? 0-60 is like 18seconds lol

EDIT: its not, 75bhp, 103lb ft of torque LOL

thats why most dont have n/a diesels lol

I've driven a clio and espace n/a diesels. The clio was a 1.5 affair. Was probably slower than my 1.4 8v GP, but it did havegreat torque - could be lasy and just use 2nd and 5th gear

The 2 litre Espace was dog slow and drank fuel - though due to the size of the vehicle was great for cruising.

Click to expand...

Very similar to when the EGR valve sticks open and therefore doesn't spool the turbo until high revs... something like this





That's 0-30mph in about 10 seconds
