not good with these..

[Dicky]

bought a HDI earlier with a TD04, 330 injectors etc while my VXR goes away for a while

Cuts out under hard acceleration and won't start unless you leave it for 2 minutes

Any ideas before i weigh it in?

[Connor]

Could be a few things, might not have been remapped properly, could be the lift pump isn't up to it

[Dicky]

I'll plug it in tomorrow see what it says, if it says anything lmao

[Poodle]

Strip for parts, surely.

[Toms306]

TD04 on a HDi? Why?

[Razorback_Rob]

TD04 on a HDi? Why?

Because bigger blatantly means better >.>

Tried explaining to an xud lad that a td04 isn't the best match for an hdi. Wasn't having it.

[Midnightclub]

If they're mapped properly they aren't too bad to be fair, but they need to be revved

[Toms306]

So whats the point? Taking away the low end pull to gain top end? Buy a petrol if you want revs and top end pull. Or VNT it if you want a compromise of bith.

[Midnightclub]

Powerrrr! Is the point is guess, but considering a stock turbo will do 160hp and spool quickly, I personally wouldn't waste the effort.

[Dicky]

It's actually not that bad, it goes really well for a HDI then it cuts out

[HDi--Power]

Its probably still using the original hp pump which wont be able to handle the requests being made and also it wont have 330 anything injectors in it.....

[Razorback_Rob]

Is the r70 pump suggested on this figure of power? Or is that the one off a 330.

All I was told is that it had 330d pump (?) either merc or BMW injectors (?) I know it has a TD04 cause I was there when it was fitted..

I don't really care if it don't have the injectors or anything really, I paid £300 for it with coilovers, lowered gti6 beam, cyclones with good tyres, FMIC etc

Just want it to not cut out when I rev it hard lmao

Well its cutting out due to lack of fuelling by the sound. I'd either look into new pump/injector combo. Or get someone to map it to a comfortable power to stop the cutting out.

I'll have a look at that first and try the map, thanks pal

If it's the one i'm thinking of it does have 330d tips on it, at least the lad who had it built for him is convinced it does.

I'd suggest having a look at the lift pump for starters. Find out if the hp pump was refurbed if you can, i seem to remember it was a scrapyard job. If it's not a refurb that's probably the issue, but check lift pump first as that's a lot cheaper to replace and then easier to sell on if it doesn't help.

And for anybody confused; the 330d pump is an r70 pump, however theres no point using it because it needs modding to fit and theres one that gets fitted to the 2.2hdis thats a direct fit.

I don't get this, it's essentially the same pump but in the BMW it flows over 200hp of fuel stock and can quite happily cope with 260hp. But apparently the 2.2 HDi R70 flows 17% more than a stock HDi 90 pump? But a stock 90 pump seems to be at it's limit at sub 200hp

Fault codes that were found;
Crankshaft Sensor
Fuel Pump Primary
Glow Plug circuit

I'll get these done first as I know for a local hdi breaking and get the lift pump at the same time

[pro_steve]

It will be cutting out because the fuel pump can't keep up with the fuel pressure demand.
This can be several things, blocked regulator, blocked lift pump, blocked fuel filter, knackered high pressure pump, knackered injectors, fuel pressure set too high in the map.

[Eeyore]

yeh its a fuel pump issue. Jonny has the same problem with his estate at pugfest.

I need some help please,

Can you tell me where to find the regulator?

look in the end of the hp mate, two torque bolts hold it in
