MBC how many clicks?

If your car isn't mapped for that level of boost bud I would be very very careful????

It is supposed to drop the higher revs you go the K03s can't hold it to red line, best get it plumbed in line as well.

 

[turboboy111]

It does drop of about 5krpm to about 1.1 bar, it was supposed to hold 1.3/1.4 bar according to the revo dealer, I had an issue with my n75 bouncing and all sorts so new it was on its way out so replaces it with the unos

 

[LEE69]

What car have you got?

 

[turboboy111]

Leon cupra auq revo stage 1 why is boost too high? Haven't had any error coads

 

[LEE69]

Mines never performed right so you boost to 21 and hold 15?

 

[turboboy111]

Well I Peak at 1.3/1.4 and holds around that till about 4krpm the drops off a bit

 

[seatcupramad23]

As said the k03s turbo will start to run out of puff at 5k rpm and boost will hold around .9-1.1 bar , if it's set at 1.3 bar you won't make more power top end

 

[turboboy111]

Yea like u said but it peeks and holds rather than peak and drop off straight away it now holds much more boost round the rev range with this fitted now

Hi, This looks like it might fix the problem with my LC.

I assume this would do the job?

you need a ball and string type MBC

I take it the one in my previous post isn't?

How can I tell and what is a ball and string type MBC?

many will say get forge unos but this is just as adequate

 

[Mark300zx]

Just to remind everyone the ball and springs in MBCs need a clean every so often as they can get clogged up, also the settings change due to various factors. so keep an eye on your boost

Thanks, I've ordered one of these so we'll see how it goes.

So is there a benefit of running a MBC on an un-mapped car? And any specific way?

 

[seatcupramad23]

the benefit is you can bypass the n75 valve and raise the boost but on a standard car not adviseable cause just raising the boost while make your car run lean (nut enough fuel) timing and fueling have to adjusted to suit the requested boost . car running lean will create very high cylinder pressures due excess heat the ecu will adjust abit to try and compensate but only to a point. i only would run a mbc to stop stupid spikes on a mapped car

Got you. I had N75 problems but since sorted. I liked the idea of keeping the car on boost longer through the rev range.

 

[co004]

Does anyone have a picture of their MBC fitted inline with the N75? I think I know what I'm doing but just for sanity really (and it's nice to see how people chose to splice their hoses etc..)
