Cause you have a boost leak or slipping belt??

Jaw_F430 · Sep 15th, 2008, 05:15 PM

what he ^^^^^ said. You must have a slipping belt, boost leak or worse a slipping pulley on the SC shaft

oh frig ............

that doesnt sound good lol i wish i could test it more thoroghly. i live in northern ireland wish there was tuners for minis here. wat boost should i be at then?

patsf1 · Sep 15th, 2008, 08:36 PM

i have had my pulley on for a couple of thousand miles now and i dont see any sign of my belt damaged ive got an alta v2 17% and i tightened the torx up good and tight wen i put that on. how would i know if the pulley was spinning on the shaft? would it not have spun off the shaft by now if it was loose??

MINI-Morgan · Sep 15th, 2008, 09:05 PM

In theory, no. It should be perfectly straight so no gradient for the shaft to spin it off. if it was slipping you'd know as it would get worse and worse over time and if it completely failed so would your engine if you didnt notice. If the SC stops then so does your water flow

I'm betting if you undo your intercooler boots. Reseat them and retighten them and you should be ok. if you hear and loud hissing or whistling when you accelerate you know there's a leak. Also when you floor it as the revs come up and so does the boost when the seals start to leak you should feel a dip in power too.

I wouldn't think it would be the pulley if you have the V2 pulley as these clamp the shaft well. I had a different type of pulley fail on me and the belt tension kept the pulley in place. You would hear a noise as you try to go onto boost if your pulley was spinning. Your belt has probabily stretched and it slipping or as MiniMorgan said your snoots boots need re-positioning.

I am on a 15% V2 with GP I/C and big valve/ported head and I hit 16psi. You should be at least 17psi. What I/C you running? Shoudn't give you that much of a pressure drop though.

Depends where and how you measure boost too

One of the issues with the MINI is that the take off for the fuel regulator and most boost gauges is on the SC side of the IC and so if the IC is restrictive or gets clogged by dirty oil then the boost goes up. Sadly the true boost on the other side is less which is what the T-MAP sensor reads. How silly is that?? The ECU see's the true boost by the boost controlled fuel regulator is controlled by the other side of the IC?? Who was drunk that day on the designing

P.s. with a 17% and stock intercooler id expect 18psi on a boost guage

Sadly boost gauges and weather conditions do vary what reality is

its a grs i/c i have original snoots on it. so it might be that i have a loud noise comming off the left side of the intercooler i took a video of it im gonna try and u tube it lol so u guys know wat im talking about!!!

MINI-Morgan · Sep 15th, 2008, 10:29 PM

No way! ditch the stock boots as soon as for proper ones! The outlet of the intercooler is a high pressure place. Think you are ramming all that air at high pressure through the intercooler and its all got to make it through that little outlet which is much smaller than the inlet.

Often I have to reposition them upto 3 times to get them to seal right.....

so does the air travel from left to right or right to left?

patsf1 · Sep 15th, 2008, 10:42 PM

YouTube - cooper s boost

ok guys that vid has been taken tonight listen out for the funny grinding noise wen i put the cam close up to the i/c. i think this might be a bearing gone in the s/c.

patsf1 · Sep 15th, 2008, 11:30 PM

ok just bought ultrik bellows there of mini mania see how they go.... watch this space lol

MINI-Morgan · Sep 16th, 2008, 12:01 AM

Flow is left to right.....thats from looking at it from the front.

Sounds normal to me! Maybe im missing a sound. The pullies are always really noisy with a slightly metallic sound and the clicking is the injectors. Cant wait to see how mine runs without the SC!

Does the boost gauge read 0 when the engine is off? vacuum looks about right too if not slightly higher than I was expecting. What airfilter are the running and is it clean?

Im still betting boost leak or bypass valve that isnt sealing.

i bought a new airfilter its a ram air induction kit maybe its limiting the air flow couldnt see how though, where is the bypass valve? if i was getting proper boost would my car feel alot quicker?

patsf1 · Sep 16th, 2008, 07:58 AM

yes the guage goes to 0 when the car is turned off.

Here it is : http://www.mini2.com/forum/engine-dr...ass-valve.html

Might be worth a read for you

Try pushing back on the valve and make sure it gives plenty of pressure back and is firmly pressed against the grub screw. Also worth winding the screw out a couple of turns and see if the arm follows it. Now test the pressure on the boost gauge at WOT in 3rd

Any difference?

Im still betting intercooler

i found the bypass valve... the steel part of it was sat tight to the grub screw wen my engine was off. i pushed it back on the rod part of it and it travelled about 2 mill and i let go and sprung back and hit the grub screw. is there meant to be much travel in this area, does this matter?? or is the idea more to do with the steel part being able to hit the grub screw without sticking between travel?

patsf1 · Sep 21st, 2008, 09:02 AM

ok guys got the new snoot boots just have to put them on now . grrrrr heard they were a mess to get on any tips??

MINI-Morgan · Sep 21st, 2008, 09:10 AM

They are easier than people say

pull them over the horns first but pull them right on and then drop the intercooler in and slide them back onto the intercooler. Just be gentle and maybe use sometime like fairy liquid to lube but I think you will have more problems with slippery fingers.

Also do them up reasonably tight but dont clamp them right down unless required as they are usually thicker than the stock boots.
