RS4 B7 Engine Strip

[RossDagley]

what's the benefit of removing these?

Mo Farrah. More powa!

Happened to a few engines now, not seen a tumble flap retaining screw though before, normally core plugs when pratts re-use the core plus.

[RS6BRIT]

What I don't get is why you'd remove the core plugs in the first place ?

[adsgreen]

Only way to get the intake manifold flaps out.

[RS6BRIT]

Ahh, I see. I guess that would have become obvious when I tried to take the flaps out. At least now I can order them in advance. Do they need pressing in or can they just be tapped in ?

[KGRS4]

Just chap them in with a socket of the same size that fits inside the core plug

[RS6BRIT]

That's what I was thinking. I don't want to thread jack but another question whilst I've got your attention ! Do I need to leave the shaft in that turns the flaps ? I assume that I do so that the position sensor still thinks they are operating ? Or is there another way of doing it ?

yup - as long as the sensors move they will not trip anything.

Thanks guys, appreciate the help. Roll on the carbon clean !

It's possible to remove the flaps without removing the core plugs, with a very low profile ratchet, I've done it before - but it's fiddly.

I've been running without manifold flaps and fins for about 6k without any issues. No discernible difference in cold starts, cold running or idling.

Is that with the factory map?
