N75 valve - how does it work

[MCB]

I hake it when we go off topic!

[ChipHazzard]

Is there a porpoise to all this banter?

to that matter is there a porpoise to the whale tailed porsche turbot's

Or are we all fishing for sense in a sea of crap

Back on topic then ...

I've heard it said (in hushed whipsers) that you can put the N75 valve from an S2 in to get more boost ...

shall I try it...? or should we rely on MRC's magic...?

I've also heard, in not so hushed whispers, that if you screw around with the S4 N75 valve, you can get it to dance to all sorts of tunes...know anything about this Jules...??

[S4TAN]

Yeah - go on Clive - be a devil!

Ummm ... I may have some familiarity with the matter of which you speak ....

[ChipHazzard]

stop carping on, you'll end up with the N75 screw police after you

Yes Clive you should, be interesting to see some before and after logs (With help so I can understand the bl**dy things!) and then carp on about it to us.

Shhhh

[ChipHazzard]

I think it might be time to sit back and await with baited breath for the logs to be trawled thru and see if there is a net gain

[MCB]

Excellent work there

[ChipHazzard]

this codding can get you hooked

I'm Floundering to find any more info on how the Turbots are controlled without it.

I've looked at every Plaice I could find on the web and could only find Red Herrings.

Gonna switch on my Tuna and pump up the Bass as I'm fed up with Carping on.

Well see. But I believe that you can disconnect or do something to the N75 thus allowing a valet mode like effect where the ECU doesnt deliver the boost. Not sure if it will run like stock in limp mode or not.

I have done this a couple of times when leaving the car places, it reduces it to the min, which is 0.4 bar of boost.

I also had a "faulty" N75 valve just there... after MRC's new map I was running around 1.8 bar ish, which dropped to, at best 1.6 bar. I replaced the N75 valve (with a newer model? two different part numbers, I believe it might be a new verson)

Anyway, straight back up to 1.8 bar ...

I read somewhere, that this newer model can give 0.2 bar extra by default... have a read of this also ...

(with a newer model? two different part numbers, I believe it might be a new verson)

What's the part number of the N75 you put in Viper? I've also experienced similar N75 malarkey (lost a few psi of boost etc so suspected the new N75 i'd put in had gone "faulty")

Also: i looked at the ECS "race" N75 on their website; the table shows it as being incompatible for the S4 - but there's a photo showing an S4/RS4 engine ... so i e-mailed them asking whether it's compatible or not ... they came back with a definite "No" ....

This is why i may experiment with an S2 N75 ... just need to find out which version to get (there are 2 on vag-parts web-site...) ... the S2 N75 is a 'slower' valve (so i'm told by someone in the know)

I will pop out at lunchtime and get the number of the new one I put in, and get the number off the older one that I took out tonight ... certainly fixed my problem!
