great, looks like lohen charged me for the wrong job!

Hi,
.... just wanted to say.....
BBR 220 conversion over 50,000 miles plus of trouble free motoring. I have chosen to replace my intercooler with a GRS version and have a Milltek exhaust manifold.

I do not track my car but all the extra torque is great on the motorways and A roads I use.

Cheers

what are your IAT reading like? and AFR? have you dyno'd your car?

Sayanthan,
Have never recorded IAT / AFR or dyno'd car as like you do not have the correct equipment to record the information. IMHO, I do not think that rolling road testing a BBR MINI ( or any conversion that uses a 19% reduction pulley ) is appropriate or accurate.

The conversion is designed to work and prove itself on the road [ when there is an appropriate amount of airflow ]. The only way to get the true figures is to capture the information whilst the car is moving. { if someone has this equipment , I am happy for them to record the information from my car }.

I hope you get your car sorted and the way you want it to be, however I think that it would be wrong for people to read this thread and assume that there is something fundamentally wrong with the BBR 220 conversion. A 19% pulley conversion makes for a great fast road car with loads of torque which can be used on the road everyday.

Cheers

hi,
i think you're right! - i suspect there are other issues with my car. paul did drive my conversion and monitor IATs as well - and they ran up to 69c at 7000rpm. and up to 55c at 5000 rpm. obviously need to repeat this testing once any potential problems are ironed out. - if the IATs remain that high - it may be worth you popping down 1320 and getting them to live test your car rather than dyno it. no harm done there and should be accurate. thinkmini also have good live monitoring equipment too. 50000 miles of throuble free motoring is great! good for you!

compression results are back:-
125 on 2 cylinders and 130 on 2 cylinders
leakdown results:
2-4% on three and 8% on one.

i understand these are okay
paul did say my cam's a bit odd. may be responsible for loss of torque. anyone know where bbr get their cams from?
maybe the cam just needs to be readjusted?? or it's not a very good cam????

they're checking the cat this afternoon

What mileage has your car done?

Not to bad for the leakdown results but I would be concerned with the compression test as the working limits for the compression on the Cooper S are 133psi-196psi, your difference between cylinders is ok as 7 psi is allowed.

Maybe someone can comment on this but if there is not much leakage then why are the compression figures very low? (Don't think BBR would of lowered the compression via altering the combustion chamber would they? Or different pistons,thicker head gasket?)

When I had mine checked by 1320 autos my results were 150ish on 3 cylinders and 135 on #2 cylinder. I took it to BMW and they fitted a new engine as they found wear on cylinder 2 when they stripped it.

I have re-checked my compression and all cylinders are 180+psi

my car's done 35000 miles. i don't think bmw will honor a warranty on a car with a modified cylinder head and 19% pulley. - i know my dealer wouldn't! so not much point asking them to.
i'll wait for further comments. i told BBR the results and they said the compression figures were within normal parameters. i'll wait for 1320 to finish assessing things and then think about what to do next.

what would be the advantage or lowering the compression???

My car had done 33k on the first engine and was modded to 225bhp but they still covered it. Total bill was around £5000 so glad it was warranty.

Well normally the compression is lowered when you fit a S/C or turbo. But the Cooper S already has a lower comp range than the Cooper because of the S/C. So I don't see any benefit of doing it, TBH I don't think they would of. Maybe you could ask them if they do lower the comp if you have to phone them for anything.

Since they dont rebuild the engines id be amazed if they effect the compression. Why would they lower it?? its already low enough....

Thats what I was thinking but why is the comp quite low if there is not much leakage?

cylinder wear?????? or would you expect leakage with that?

[blaze6]

some people have been asking if the relatively low compression results are due to the type of cylinderhead on the car - i have no idea! i've attached some pics from the conversion - maybe someone can tell?

Well on mine it was cylinder wear (and I would expect leakage with that).

Your compressions are quite even though across all cylinders

What did Paul say about the figures?

he said it was spot on. not sure what he meant by that really. he also said i had a "funny cam". i don't know how you work that out from a leakdown and compression test. would this lower the compression? my car's low end torque is also a lot lower than it should be for a car with a 19% pulley, so still more questions than answers.

Well the leakdown is spot on. Not a massive % being lost


I wouldn't worry though as when you get the car back from 1320 Autos I'm sure it will be fine and producing the power it should

just posting an update:-
so far things discovered:-
my horn doesn't work!(not used it for a while so never realised!)
front silencer on miltek exhaust needs replacing (under warranty)
my koni fsd's are defective - making excessive noise (which i thought were coming from control arms!) going to see if can swing a replacement next week under warranty(i bought them second hand, koni's rep's in spain at mo)
cam timing may be out or just not a very good cam - probable cause of low end torque as engine is sound - may also be reason why the compression testing figures were lower than normal. i've heard newman cams recommended by quite a few people = may need to get one of them.?the same as the 1320auto cam???

outstanding issue - what to do about high IATs and engine leaning out. ordered GRS which may arrive sooner than expected. had a chat with a guy from red dot racing who bought a supercharger (ported grey coat) from me today (he's experimenting with it) who says my 380cc injectors may not be at maximum capacity, so may just need the fuel map remapped??does this make sense? he also said consider a 15/17% pulley....

Sayanthan,
Keep the updates coming..... very interesting thread.

Hope I all gets sorted soon.

.....Changing camshafts (to a performance one) often reduces compression ratio and therefore compression readings. It is often possible to increase compression to compensate for this and therefore get the best from it, you certainly wont want to reducing it further when using a perf cam.

have you got a bbr cam? it's probably worth speaking to neil (BBR) and seeing what he thinks? checking the cam timing and refitting it i understand is quite a long job...if iask him to check it and the timings out great, id' get it sorted FOC. but if it's ok, i'm in for a 3-4hr labor charge!!
