Intercooler pressure or vacuum?

Pressure.

- I can pull the split together with staples, but need

Whatever the boosts set to. So about a bar.

Its under pressure, is that not obvious from turbo-engine fundementals?

Anyhow, i doubt you will hold it together and sealed with "staples" or the like, so he will just have to travel about under normally aspirated form + loud hiss form until he gets a new 'cooler.

PS the 90bhp TD runs about 0.9 bar boost.

Yes just under 15psi and I hope the staples do not break free and enter the engine.

Tim.. brought next idea :

Er, no - I have never had need to study diesels and had no idea what an intercooler might be or even looked like. `

Sealed up and refitted last night and no phone calls of complaint about it breaking down yet - these were industrial grade staples, folded on the inside so not much chance of ingestion. It came out of the garage with a split in the end box after a 'professional mechanic' fitted a new pump. The mechanic had tried to Araldite the end box split together, claiming the extra power provided by the new pump had caused it to split.

Thanks for the help :-)

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Harry Bloomfield saying something like:

Blimey. I must fit a new pump, pronto. All that lovely free extra power.

Blimey, how fucjed was the old one.

They're not expensive down the scrappys.
