High there what is the air pump for on a hawkeye 2.5? And do i need it? As i see cosworth do a blanking plate?

thanks morgan

 

its to do with emissions and runs at startup, not needed and can be removed, it just blows air into the exhaust from what i gather

 

^^ this, but you will get the CEL light on the dash if you remove it. You will have to get a mapper to delete the fault codes.

 

Is there any advantage in removing it?

 

I think its a case of not if it will break but when and there about a grand to replace. If it's not there it can't break. Plus it clears some space under the bonnet for things like an oil catch tank ect.

 

Spot on, cheers mate

 

thanks guys so the pump on the side its literally just unplug it and fit the blanking plates? im looking at a remap soon after next mods so might do it for that

thanks for your help guys

 

The blanking plates fit on the engine, not the pump.
To fit the blanks needs the entire air system removed - pump, 2 x solenoids & 2 x pipework runs.
I've only done this with the engine out during a rebuild.
I can't see how this can be done with the engine in place as there are too many other items in the way and one air pump is in a very tight location.

 

ive got the engine out currently as am rebuilding her after ringland problem

the pump is behind the battery isnt it? where are the solenoids?

 

Both next to the air pump but connected to the inlet manifold. One of them has a really awkward bolt holding it to the manifold. i had to use all sorts of combinations of angled sockets and joints to get at it.

The two pipe runs are chalk and cheese to get off. The passenger side is easy, the drivers side runs close to loads of other pipes and behind the turbo before it dives down. Its easier to get the turbo off and remove this pipe TBH.
Where the pipes attach to the engine is where the blanking plates should go.
The Cosworth items were an outrageous price when I did mine, so I made some up in the workshop. Perhaps someone is doing a couple for a better price nowadays?

 

I'd recommend anyone thinking of having there car mapped to have all the relevant codes deleted from the ecu then if it does fail just rip it out without compromise

 

Bringing this back to the top to ask you guys a question.

I've just done this mod as mine as the engine is out at the moment, what do I do with the breather pipes that come from the heads and block? Do they need to be blanked off or do they still need to vent? Cheers.

 

Blanked off. Cosworth do the blanking plates.
