Hi need a lil help

I have a just bought a ERA, it drives and boost fine utill it gets warm well the gauge is showing 90 c
Then just as it comes onto boost it starts missing, it has done 12000 miles from new and doesn't smoke at all,

Any ideas ? Hope its notting to bad !

Cheers Jambo

Could be a Split part throttle lean off pipe.

In the 13's at last!.. Just

Cool cheers which one would that be without sounding stupid !

The one that goes from one side of the carb to the top.

Also check that there's oil in the carb damper.

Part throttle lean off is the thin blue pipe in my picture, should be easy to find then :)

Cheers chaps, the one off the carb is blanked off and the one out the top is going to what I think is a bleed off thing ?

Jambo

Pop up a pic.

Sounds like it's not standard.

May just link the two back to standard a see if it makes any odds ?

put a new piece of pipe on as per carl's pic with some clips.

If its still the same try clamping the hose to block it and run it again.

Here's some pic's of how it is now with the bleed off thing ? were would i put the pipe coming from the waste gate to ?

need to know where that pipe goes fella. however it looks wrong to me.

If something is worth doing, it's worth doing half of.

that pipe goes down to the waste gate thing ?

google it

I should have said it comes from the Wastegate Actuator

if that makes sense ?

I cant tell from the pic where it goes at the carb end. Is it on the manifold or carb? It looks like it's on the carb.

Either way. That pipe should be plumbed into the fiiting on the compressor housing.

That is wrong that pipe should go from the actuator to the compressor housing, with the bleed valve fitted inline.

don't think who ever put that bleed thing on had a clude what they where doing ! they blocked the one off the compressor housing and took the waste gate pipe to the inlet manifold ! so i was getting full boost nearly a bar now i have 0.5 of a bar is that about rite ?

jambo

Yes that's about right.

Get a pic from directly above the carb.

only trouble is i don't know how long it has been like it and how much damage its done ?, i read they have an over boost valve but when does it kick in 10 psi ? how much will a standard engine take ?
