Would it upset the ECU/fuelling?
(GM 2.0DTi, which wasn't running right before, but then about a month ago started running *really* badly)
-
Yes, tape it up to prove the point
Scratch that, it's pre maf
-
I'll try to get another pipe as a matter of course, but was thinking if this could be the reason for the sudden lack of power and the surging that has happened in the last month. It had hardly any power before ;D
-
If you mean between air filter and MAF then, altho im not that 'bright' on engines i cannot see a reason why it should.....your just taking in unfiltered air
-
How much power could possibly escape :o Anything less than 75bhp would make it undriveable, surely :-\

And presumably all the rubbish contained in it, including dust and heat... which might be where the power is going, as the intercooler will struggle to cool hot engine bay air enough to increase the density for the turbo to get stuck into :-\

For my benefit, pipe I need is 90530766

I never have a pen when I need one ::)

Even after Master replaced the turbo, I doubt it had anywhere near 75bhp. Currently, I'd be surprised if it had 50bhp. It manages about 80mph as long as its not uphill. It will just about redline (5k rpm) in first and 2nd (but its hard work), no chance in 3rd.
Anything above 3k rpm (even in neutral) it smokes like a bitch

Also, anyone near me got a 2.2DTi Omega, and be prepared to lend me their MAF for an hour or 2?

Got one somewhere, would have to go look.
Won't be passing next week though. :(

Could the split bugger the maf if crap is getting in? Hence the request to borrow a maf I suppose. Any splits after the maf, might also be possible?
Although, master says, maf does very little on the TD's, so .... Hence the request to borrow a maf... I suppose ;D

It does more on the dti's

Interesting to see. Is it a fault. Or as designed?
What was the original power output as it left the factory? Do we know?

Is it before or after the turbo? Guessing before but can't see why it should split without some pressure behind it :-\ unless it is collateral damage from some "event" :-\ :-\

A claimed 100bhp. Approximately the same as other 2l DBW non common rail tractors from the time.
I had a couple of Rover 400's with a (claimed) 105bhp L series tractor engines, and they were both decent engines to blat about in, and always gave over 50mpg over a tank, unless I'd driven most of the tank (then it was usually mid to high 40s). I'd kinda expected the Zaffy DTi to be around the same ballpark in performance and economy (a little less due to extra weight and height). Maybe my expectations are simply too high :-\

Before the MAF, thus before the turbo.
Probably a combo of jubilee clip (crap things), age and vibration (turbo obviously bolted to engine, airbox obviously attached to chassis, with no concertina pipe, so this takes brunt of the vibration in this particularly crap GM design).

Surely the Zafira weighs a lot more than a 400? Worth checking the weight figures?

Is there any way that the inlet pipework might collapse due to suction inside the pipe?

I've seen a 3.2 Omega that drove like a 1 litre due to this. Previous accident damage had damaged the pip into the bottom of the airbox and it closed up under full throttle.
A split here would cause warm air to be ingested, On a petrol car I've had that cause a noticeable blunting of performance but on a tractor it goes through the intercooler afterwards anyway, so not sure warm air would make much odds.

I am making an assumption that a 400SLDi is about 1.2t and a Zaffy 2.0DTi is about 1.4t, so I had accounted for a couple of fatties in the 400. But, yes, maybe I should check weights ;D
