Anybody with Derv Drifting EXPERIENCE

I reckon for towing the economy would be better, since the extra torques would help it haul itself along better. Would imagine fitting a decent intercooler would help quite a bit too.

Yah, torques would be nice cos the autobox likes to drop 2 gears n 2 overdrives in between at the slightest suggestion of an incline.

My trailer does weigh a solid ton though, which i dont suppose is helping.

Basically, i'll sue your ass for much veg oil if the Bonatron "go on chip it" guarantee fails me

Lots of interesting ideas, it's a difficult arguement! Again, one of those things thats only answered with trial and error!

I wonder if the "rev range" thing is more myth than problem, I mean in a petrol you're still only using say 4000-7000rpm, whereas I suppose I'd use 1500-3500rpm for example!

T.K There are a few (zim zimmer powered) derv Omegas skidding in Scandanavia. They run massive truck turbos.

I figured I'd have a go at fitting a holset VNT. Wonder if it could help to utilise the rev range I would have better!

Slidewaysdrifter john with the above car said it is a little better if he drives it normally but he also says that around town and cruising the car is not boosting at all now as it later in the rev range but when its being driven hard its poor, as in he says worse than the petrol equivalent and he loses all the benefits he bought it for in the first place and the engine is ubber heavy to boot and has massive understeer problems

That puts me off alot as I might aswell buy a 320i if my advantages are outweighed!

Anyway, if I buy it I can sell it! A welded diff, set of springs and a bleed valve aren't gonna break the bank, quite honestly I'm not sure I can lose, and besides, I may even get lucky and make something of it!

[Bon Bon]

Are you sure he doesn't have massive understeer problems because the car is scraping the floor??

I'd stick with stock turbo and get it to the 185~bhp mark and lots of torques.

And didn't realise yours was auto Ren, 22mpg towing with an auto is pretty impressive!

Trust me, he knows

Heres a vid of someone who looks a little bit like Gmaster drifting a 325td round a roundabout. Watch right to the end for the surprise (for the cameraman at least)

[mav]

Nice, I guess that puts what I was gonna say out of the window (ie maintaining enough rpm with a deisel)
You do know its illegal to go round a roundabout more than 3 times?

Wow, the similarities are overwhelming

I'm pretty sure the roundabout was damp. I'm reckon il give it a go anyway... I did notice last night there's loads of straight 6 bm's around for under a grand, whereas finding a tds is a bit hard, we'll see...

BonBon: I'd stick with stock turbo and get it to the 185~bhp mark and lots of torques.

You think the vnt won't have advantages for torque then?

[Bon Bon]

Not if it gives you a 500rpm powerband. I'd rather have less torque and a stock powerband but just...more.

[quote=Bon Bon;630145]Are you sure he doesn't have massive understeer problems because the car is scraping the floor??

probably but as we all know diesel engine's are alot heavier as they are all cast well older ones are not sure about more modern stuff plus he is just starting out, and as said i have never driven it and it could be fine or just set up wrong as you say bon but the pic is about 6 month old and the back is as low now

I thought the point of a vnt was to give you a better power delivery, i.e. fast spool up with power at higher rpm also?

[Bon Bon]

I have no idea on the specifics of bigger turbos on the bmw diesels I'm just going off what was said about the red e34 above with a bigger turbo, and that I've been told that a chipped 325tds is pretty destructive.

No probs, cheers for the input either way!

I figured the turbo would be a worth while thing to look into as they run 15psi through a T25 standard to only produce that 143bhp

[McLarenboy]

Hey Bon Bon - when you get a chance, could you reply to my last pm?

cheers

[matt]

how do the bimmer diesels cope with veg oil? I had a diesel escort that loved it, just poured it straight in the tank in tescos car park. do they have gay sensors and electronics to get clogged?

[Ali]

If they run a T25 standard couldn't you do a cheap swap to a T28 to run a bit more/have more at the top end.

Granted diesels don't rev that high but surely its going to be more the gearing, and as they make massive torque at low rpm's you'll probably still have the equivalent pull from x speed to y speed as a petrol.

Only diesels i've driven have been a Ford Galaxy 2L tdci, 110bhp, 2000rpm pulled strong, by 3000rpm it was all over and also driven a Volvo D5 2.4 straight 5 163bhp, so so much better, pulls from below 2k to 4.5k fairly linear

i looked into this as i used to do it in my astra, basically, all the research i did lead me to the conclusion that it was much more bother than it was worth, proper biodiesel maybe, but straight veggy oil is a no.

just out of interest, did you escort take a lot of starting? my astra took quite a lot to start it, once it was running it ran fine, and once up to temp it ran loads better than on diesel, but it took like 6 blasts of the plugs and maybe 15 seconds cranking to get a smokey, not quite 4 cylinder start...

[matt]

mine always started fine, I just let used to wait until the glow plug light went out, then key off and do the same again. I never went further than about 70% veg oil though, but once it was running the smell was the only difference (and the tiny running costs of course haha)

[Jimthejunior]

Veg oil, depends on a whole number of different things. Biodiesel is totally differnt to using veg oil. I'l be putting a twin tank system in my van when i get round to it.

Tad greasy... apparantly, cold but not wet...So I heard

The problem isnt the power its the speed, 2nd in a td is good for what 40-50mph? not enough to get the wheels spinning at the speed you want, so its a case of have to shift up and use the tourques. Oh and there was a far bit of wheel rocking to keep that going, redline in 2nd and not going major quick...

[ドリフター]

drifting diesels is fine they have alot of torque. i drive a Range p38 with the bmw 2.5 in it they are normaly slow as frick but if u advance the timing slightly up the fuel and boost get it mapped and they fricking fly. my range does anyway i cant drift it like i used to in my shogun as its permenant 4wd with air suspension its like an upturned turtle when it goes.

Only thing u will find is they smoke instead of flame lol.



Rain helps alot. i owned a 325tds for a while but it was automatic so i couldnt hold the revs up and clutch kick it but in the wet it was great fun. just keep the turbo spooling and u should be cool.

[jamespa28]

When I started this thread, I was thinking about your shogun video... only video I've ever seen of somebody drifting a diesel! Bit crazy to be honest, they're horrible to drive before they break traction!
