My new maff

Well my new maff upgrade arrived but there is no direction of flow on the case
I'm assuming the I should fit it with the connector plug facing the way the oem one is but is that correct?
Would a picture of it posted up help?

Re: My new maff

What is the new maff for?
Have you thought about putting a turn on your turbo actuator arm?

Re: My new maff

Hi
What do yo mean
I did not realise they were adjustable
New maff has no mounting luggs ans it's done over 100k and I believe that's why my mpg is lower than usual

Re: My new maff

Little trick to get higher boost pressure, you can shorten the actuator arm by a half turn or one turn or more. apparently one turn is about 1psi. I was thinking about doing a half turn for just a touch more boost, but turbo is in a very cramped position to adjust it. I also want to clean egr but in really awkward position and I think you have to remove cooling pipes and stuff to remove it.

Re: My new maff

Turbo on mine is on bottom at the front
I can get to the accuator OK
So..... Shorten or lengthen for more boost?

Re: My new maff

I believe you shorten the actuator. It makes the actuator open later and under higher pressure. I got the little retaining C clip off of my actuator arm, but had trouble loosening the retaining nut on the arm as a bit awkward to get any tools in there as it's right up against the front of the engine bay in mine.

Re: My new maff

I have't yet, still trying to figure out how to get in there to adjust it without removing the entire turbo. Definitely do a little research on it first

AFAIK Euro 4 75 hp's have a fixed non-VGT turbocharger. But i don't know if it has a wastegate actuator or something...

Re: My new maff

My turbo defo has a accuator rod on show which I can get at as in the past the accuator was sticking and kept going into limp mode

Re: My new maff

Yeah 75 has a fixed and the 95 has a variable geometry. It's the only hardware difference I've found. I wonder how easy it would be to stick a (larger?) variable on a 75 and have someone custom map it. And whether it would be worth it :P

Re: My new maff

The difference between the 75 and 95 is just the turbo so your idea will be possible
I had this option when I had my recon engine but thought leave it as I have a nice pokie engine with over 100 bhp with chip

you wouldn't be able to stick a variable turbos onto a engine expecting a fixed one it would likely throw a eml up due to the differing boost profile's
