fitted t4, when i give it sum wont boost properly over 25psi, sounds like wastegate opening cos can hear chatter from filter, got -34 actuater which is 2 mnth old, any ideas y this happening

 

bring it down on the weekend dude, ill have a lookie for you

 

Leaking boost pipe,dodgy diaphram on dumper? Why a -34 on a T4 Rob??

 

Thats compressor surge mate..
DO NOT drive it with this condition active as it can cause VERY serious damage indeed.

 

This will answer your next few questions i imagine...

FOOOK ME!!!! I thought it was that as soon as I read the symptoms...

I am amazed at myself ... see I'm not just a fat ugly face

 

thanx stu, now i no wot it is is there anyway of stopping it or is the turbo just no good 4 my car

 

Stu totally mapped out all the surge from my MD240... In my opinion the turbo was a poo design though. Other people have apparently had alot of success with them though.

How was Daz's dads MD240R Stu, surgetastic or was it ok?

 

You twat.. ive spat fookin tea all over my monitor again!! What a damn waste of great Tea!!



Live mapping with air injectors is step 1.
As said above have a browse of that post for far more info on what exactly surge is. (Try to ignore me and Mike arguing )

 

If you don't have any air injectors Rob, I have a set for sale with the 12 position boost pot.

 

Well,
It wasnt as bad as yours if that helps, and since the head spec wasnt as good as yours it should have been worse really mate

Ran 1bar from 2200rpm up to 4200rpm then 35psi peak at 4300rpm and 32held to the 7500 limiter...

Maybe they have revised the compressor or turbine mate

 

i can just see it now..Porkie's developments

 

right thats sorted i got air inj, put kettle on stu be up in 5hrs lol

 

thanx 4 advise guys, pf come through again

bell u sat gareth

thanx 4 help on fone stu, u da man

 

wastegates DONT make the chatter noise, EVER!

deffo needs a remap tho rob, that thing flows a lot of air! dont wana break it before its ready!

 

i'll be down the docks mate, a little hungover but ill be ok

 

Mine was the smaller non 'R' jobbie Stu. Seems bigger IS always better

 

Doh nightmare Rob!! nothing is every as simple as it seems eh??

Sure you will get it sorted though mate

 

Was it? Id have sworn it was the "R".
My memory is shite

 

you nutter
