Well, took my standard 02 Cooper along to a Dyno Day on Saturday and to say I was impressed would be an understatement. I was up first so had no previous runs to compare the readings to so when the graph showed 127.3 I was a little surprised!

The cars run after this all read pretty much as they were expected to but there were no other MINIs there just Minis unfortunately so nothing to really benchmark against. My unmodified MPi Mini got 63.9 versus 63 claimed standard so I feel the Dyno is pretty near the mark.

Now I know that you should take estimated crank power figures with a pinch of salt but all the same I'm as happy as a Pig in the brown stuff!

Anyone else had similar experiences?

hmm...pretty high for a standard Cooper. now i'm wondering why i got less than 100whp when i had mine dynoed...hmm...

what were the weather conditions when you had the dyno run? wheel size? and you're bone stock, right?

My Dyno run, with a remap, playmini cat-back exhaust and a k&n panel-filter...

Done on very new, auto-calibrated system.

Was a cold, damp morning which would have helped a lot I know. Car is stock as far as I know, bought 2nd hand from a MINI dealer with standard airbox and filter - I suppose it could have been remapped but I don't know how I would tell. Is there an easy way? Running 17" S-Spokes - would that have made a difference?

Still happy with the car regardless of the numbers, always has pulled like a train from 4K revs!

I put my cooper on a rolling road a year ago and the results surprised me too. I haven't got the curve to hand (although step7 it looked exactly like yours in terms of fonts, layout etc) but I had just over 99bhp at the wheels, worked back to be 126bhp at the flywheel. My father had his car tested at the same time which should have been 136bhp, but was only 130bhp. The car is completely standard (i've had it from new), standard ecu, standard exhaust, even standard replacement runflat tyres etc. I've never known whether to trust the results or not (it's very easy to believe them because you want to) but I've always suspected it can hit 60mph in under nine seconds. Its always had Optimax (to give me the extra 0.5bhp). One thing I'm fairly sure is that it has at least 115bhp. My advice to anyone who mods is test the car beforehand.

Step_7 · Oct 1st, 2006, 07:41 PM

I had planned to do some mods to the car over the winter which is exactly why I had it on the rollers to get a baseline figure. The place is really local to me so I hope to be able to get a good feel for what individual mods do to the car's performance by testing at each upgrade. Want to keep it simple really - probably panel filter, Bluefin and an exhaust of some sort, not really decided yet - depends on overtime, pay rise and year-end bonus really!!!!

SamHarrison · Oct 3rd, 2006, 09:46 AM

Just had mine done at the weekend.

I have a 51plate cooper with

K&N 57i Induction kit and stainless cat-back exhaust system

129.4BHP

BlueZed · Oct 3rd, 2006, 04:09 PM

Hope your latest gearbox can handle the power Sam, saw your life story in Modern Mini, must have been driving you bonkers!

JWF · Oct 3rd, 2006, 11:10 PM

its a weird thing dynos and dosnet translate to the road due to various things but i take it as a guide for tununig work my cooper made 129.1 unmodded but was on a absolulty balticly cold day and the fan at this place could have powerd a plane etc so im guessing im probs closer to 120 bhp but a mate ran his cooper (same build month and year) and he has induction and a play mini cat back and that gave him 1 bhp more than mine but it did give him a better torque curve so we figured that all the mods for the cooper dont relay start to work unless you have a re-map then have the head and maifold and throttle done as well

That's the key really - each RR will be different, so if you can use the same one, as similar as possible conditions (temp, etc.), then you will get a good idea what each upgrade is worth. However you still won't be able to say categorically what your flywheel bhp is/was, just "doing such and such mod gave me an increase of 5hp".

Yep, what you really need is one of these...

...Getting your engine out of the car may prove to be a tad expensive though!

it does so far...

damn it i have had so many problems....

since that article

my horn went
the clutch slave cylinder split and a "ROCK" hit my windscreen (ok maybe just a big stone) and some ***** hit my door with theirs and left a nice dent in it...thanks

SamHarrison · Oct 5th, 2006, 04:27 PM

is t w @ t really an offensive word?

BlueZed · Oct 6th, 2006, 08:26 AM

Your car seems to be having a seriously tough life Sam, what's the mileage and age of it now?

SamHarrison · Oct 6th, 2006, 09:16 AM

it's born on date is september 2001. it has just done over 61,400miles

BlueZed · Oct 9th, 2006, 11:20 AM

I guess they didn't make the first few the way they should have done! What gets me is that you got through so many boxes after that! The guys reconditioning them should be shot! Would you consider dropping in an S box if this one goes pop?

What He^^ Said...

SamHarrison · Oct 9th, 2006, 01:17 PM

I think more likely would be a Getrag box...

Lawrothegreat · Oct 9th, 2006, 06:19 PM

It has taken a while (nearly 40,000 miles), but my getrag finally feels slick and precise.
