Yup the, intake manifold!


Mushin would it not be safer to take the reading from the turbo?

i.e 2 bar at the manifold is going to be more at the turbo. Hence working the turbo harder.

Be good to see this diagram.

No, because that's not the pressure that is going into the engine then.

.....due to pressure drop as the air passes through the pipe work, intercooler or chargecooler, and then throttle body :)

Do I have to finish your posts for you Mark lol ;) :tongue:

That bit wasn't needed as I knew that lol ;)

Just wondered in terms of overworking the turbo. Readings are usually taken from the Turbo. so if you then take ti from somewhere else and try and get say 2 bar there the turbo is working that much harder.

I was thinking of the poor turbo

:lol:

Nope, readings are taken from the inlet plenum as you need to measure how much air is going into the actual engine, not what the turbo is producing.

Be nice to take readings from both places then work out ho efficient your inter/charge cooling is.

But what about when a turbo manufacture produced a flow graph for a turbo? thos readings etc are taken from the turbo. So if it is inefficient at above 2 bar but you run 2 bar from the plenum then the turbo is past its efficiency range right?

My line of thinking that spurred on the post was with regards to the feed thats taken from the turbo for the actuator onthe stock turbo. I completely forgot that the actual boost gauge reading was tee'd off from the plenum feed by the diag. box.

But then the fueling would be incorrect.

Fired it up for the first time after a long time yesterday and it came alive first time. Put in a few settings on the Motec and got a steady idle at 1100rpm. Car sat for 2 hours at tick over. Slight fuel leak, but resolved that yesterday.

Car sounds sweet as a nut. The intake manifold sounds well sexy. Has a unique resonance to it.

Car goes to Adrian for live mapping on Monday.

please update again once mapped :thumleft:

when the car hibernates do you use a battery conditioner or anything, or just remove it/ recharge before waking it up ?

The battery was flat as a press. Stuck in a new heavy duty racing lightweight battery :)

Too right...its been a long time coming!

It sounds absolutely lovely, just at idle. Very racey. Can't wait to have 30psi through it :twisted:

That escort is an animal on track. Its been runner up for the past few years, in the series it races in, but is favourtie to win it this year.

Cossie YB turbocharged lump with some serious grunt...were talking 400BHP / 450LB-FT out accelerates most things and has the balance, poise and handling to match!
