1320 check engine for bhp loss

[patsf1]

I called 1320 Autos the other day to discuss tuning. They said some people have low hp cooper s and others have higher hp than 163/170. Also when we take are cars their we can ask for a dyno to be done. Then they can tell us if we are the lucky customers or unlucky ones whatever the case may be 1320 will cure your engine before starting to tune. This sounded very good to me. Now i would like if someone could tell me what are the factors of having a lower hp s??
i really would go to 1320 myself unfortunately i live in northern ireland and i'm on a budget and prob speak for a lot of other mini enthusiasts. plus i like to get a good spektrum and i will take all of your views into cinsideration. cheers and thanks for reading

Mainly compression an leaks are the problems

[Jaw_F430]

What he^ said, if you have poor compression and leakage then the mods you do will not reflect the expected bhp gains

[MINI-Morgan]

Compression and boost leaks are the main causes. Sadly its easy to get useto it as well so often people dont even know.

[patsf1]

great stuff guys. where and how would be the best place to find the leaks and how would or could i resolve?? thanks

[patsf1]

does any one know??

[James@fomsport]

Paul and co @ 1320 are good at finding and even better at fixing them

Need to do a compression check to see if you are down. If you are down you will have leakage and then you need to find out where it is going: past the piston rings, through valves etc.

You can also check your boost pressure to make sure you are boosting to what you should be.

[MINI-Morgan]

What he said ^^^

Compression test. If its down then you need to know why. A drop of oil into the cylinder will tell if its the rings for not but most likely you just need to retorque the head bolts or new gasket. A leakdown is the way to find where it is going and is basically compressing the cylinder to finding the airleaking.

I would consider buying or getting a local garage to have a compression check, its as easy as changing spark plugs.

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.

guys compression air leaks etc could be the cause. But the biggest factor is the blue print of a engine.... Engines are build to a blue print, and can have + or - a few thou so some engines will be down on power, some will have more. Straight out of the factory every mcs wasnt 163 they were all maybe 160/165/167/159 etc etc. Thats why when you blue print a engine you get the exact factory power as you will use all the required measurements. There is not much le-way in it being loads out as engine would be scrap, but a little tiny bit they will accept. Hence the 2-3 bhp loss or increase!

Also depends on break in process to a reasonable degree but do remember not all engines leave the factory with the same size bore too )

thats what i mean, everything with engine bores etc!........ I disagree with the break in process!

break in is always controversial....... mine was driven with large amounts of throttle and mineral oil but then thats me and mine isnt factory built.

mine was driven like an old man and fully synthetic, with first change at tlc,
and goes like stink ....
but there again i didn't know any better
