1320 check engine for bhp loss

[Johnno]

break in process does definetly not give you more or less bhp

know this is a bit off topic, but where are 1320 based? some reason their website doesnt work.

Think their website is now 1320mini.com

Perhaps invest in a boost gauge?

And a BIG common problem is a worn drive belt.

If you need talking through any of the process please give me a call.

ok i got a boost gauge installed but im only boosting 12 psi max and ive got a big intercooler with 17% pulley why is this?

[MINI-Morgan]

Cause you have a boost leak or slipping belt??

[Jaw_F430]

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 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]

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]

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 so u guys know wat im talking about!!!

[MINI-Morgan]

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?
