QLD MINI Owners [The Usual Suspects]

[scolburn79]

Also when dynoing, the KW/Hp is a nice number to see high But that isn't what you feel when you stand on the go fast pedal. That is the Torque. So the higher the torque you see the more you get shoved into the back of your seat, and the more of a smile you get on your dial

I went to a (QR) track day last Thusday with my bog standard MCS R56 and managed my fastest lap (Clubman Track) to be 1:12 with Run-flats a- squealing and driving like marshmellows. Not too unhappy with that. The fastest lap on the International Track was 1:37.5 .

To cap off a good week my JCW kit was fitted on the Friday and now unladen it definitely goes a bit better.

[n5290066]

I have had the new IC and IC muffler-delete hoses fitted and put her on the rollers.

Did the mods make a difference? Yep, pretty damn good improvement across the entire rev range. I have had a minimum improvement of 15% with a peak improvement of 18%. Plenty of power and torque is available sooner.

I am now pumping out 160HP (120KW) at the wheels - plus I now know how to calculate the max torque figure accurately from the Dyno readings. Please remember if you are reading these figures down south or in a cool climate in the states or Europe, that Brisbane has a sub-tropical climate and the ambient temperature in the workshop at time of testing was 36 degrees C. Geez it was hot when fitting the IC!

Obviously in winter or in a cooler climate or even when i take it out onto the road these figures would be considerably higher (it certainly felt so when i took it for a run anyway)

At the flywheel, I am now producing 281nm of torque and 199 hp. This is interesting because the JCW tuning kit is claiming 17hp and 10nm. If these figures are accurate (and in the 200k i drove with just the JCW kit on i kinda doubt it) It means i can claim that the Alta IC and IC pipe replacement kit added another 31nm and 7hp. All i can say is- no way. The IC made a massive difference in the way this beast drives. The only escape hatch the JCW kit has is that its supposed to work optimally after 1000kms so i guess the only way i will know that is to stick it back on the rollers sometime after the Byron bay ClubMini run i guess. Geez, if it does improve it'll be scary! Bring on the cooler weather! Saddle up!

Please remember that all my calculations related to torque are based upon an assumed diff ratio of 4.1 and an assumed 4th Gear 1:1 ratio. If anyone can provide me with figures that are different and claimed by BMW, please let me know and i will be able to recalculate more accurately. If you do have them, please let me know where you found them as i have been looking for a week now and my dealer has not been able to help.

Having driven the car now, it is clear to me that I need to get some rubber that will do a better job.

The run-flat tyres and wheels, even with the DSC on, spin far too freely now in too many gears and the blue meanie has a real rally feel and sound to it now. I have some whistle coming through and a few other pleasing noises coming into the cabin when the peddle is mashed so if anyone is considering the change to an R56, you won’t miss your supercharger whine too much! See you in my rear view mirror.

Hahaha nice steve, get some eagle F1 GSD3's you wont be let down ! and they are awesome in the wet to!, on another note my mate picked up his new R56 yesterday after trading in his xr6, havent seen him stop smiling yet !, also bris mini as a present for me bringing him in gave me some shinny new bonnet stripes free and a keyring !, here are some pics of my new stripes and his car. now i have to con him to come to byron bay !

[scolburn79]

Hey Steve, I might be looking at you in mine I have 143.6kW at the wheels or 192HP. That is a basic tune too. Haven't got my Torque bar yet, they will do this when I take it back to get properly tuned. For anyone out there that reads this, DO NOT PUT AN OVERSIZED CRANK PULLEY ON YOUR CAR!!!! Reason:- Creates too much boost. My car runs 17.5 pounds of Boost. Fair enough to have heaps of boost, but to get that boost you need to spin the supercharger faster which means more heat which means the oxygen is minimal!! So all in all they have had to take timing out to compensate for it. So that figure of 143.6kW will only get higher!!! My aim now is to re install the Stock size Light Weight Crank Pulley to reduce the amount of boost which will reduce the heat coming out of my car. The next aim is to put the new exhaust headers on and the new Cat. Then take it up and put it back on the Dyno to see what is happening!! The cool thing about this Unichip is that I can use it to trigger a water pump to come on at about 2000RPM to sprayer water on the Intercooler and also when I am at Idle to Spray Water on the Intercooler to cool it down as the Air that comes from the Supercharger is just circulating. So at the moment, the Water/Meth is giving me 13kW at the wheels. This too is only going to get better. So this is the story so far. To Be Continued.....

Looks nice...I have been trying to convert my friends to MINIs for years, you've done well.. Perhaps you need to convert yourself to an R56 too..

[Minipnut]

not yet charles <3 the whine to much, we did some comparing, and the turbo does have lag, but not much, rolling start 40km/h both in 2nd, ~3000rpm i seemed to pulll away from him quite quickly to about a 2 car lengths ahead then he started to catch up ~ 85km/h but had to slow down beacuse we were testing on a closed off "private" road next to my house to be safe and it goes from 2 lanes to one :'( we even switched to eliminate the driver factor same outcome, but i do want a sport button though sheesh !

[n5290066]

Callan, nice test for a supercharged mini though. 3000rpm is where its starts to work. Roll from 1500 in any gear and the turbo will have the punch on you. Loads of torque! Nice stripes on yours and congrats to your mate. I assume that his is the dark silver? Its one of the two colours you get exclusively on the R56 CS. Mine is the other colour. Regarding the tyres, yes, i have been recommended the Eagles but my mechanic ( who races) reckons Kumos are the go. A bit cheaper too and they get up to 25000kms out of a set with great grip. I will need these prior to Byron. Also looking at bringing in the Konig featherweight Carbon black wheels off of the ALTA site. They will cost me AUS$620 + transport. I got a quote on the same thing from a dealer here in Bris and he wanted $1400 for them!


Scolburn, is yours the red one i saw at Show & Shine? It sounds wild. Have you considered a front mount IC to remove it from above the engine and then you can use the bonnet scoop to bring cold air into you filter box. Sure there is some piping but aside from chipping (which i am leaving to last) cold air boost is king whether its turbo or supercharger. Mind you the meth has a similar effect. My Mini dealer is looking at a NOS kit on his R56 which is another way to cool things down.

Am off to Toowoomba today so it'll be good to bed some more kms in and get closer to the magic 1000km mark for the JCW kit. Hopefilly that will release a few more pony's.

[scolburn79]

Hey steve, yes that is me. I really wish I could get a front mount for it. If you know of a place let me know!! I am look at a water to Air Intercooler as I have heard good thing about these units. Also your mate at the dealership had better watch himself with the NOS kit. Because if he gets caught by the coppers, they will just take his car, no questions. NOS is not allowed on the street. If he does he will want to keep it well hidden or take the bottle out when not using it.

[Minipnut]

steve its true but, if it were a race, why whould i be starting from 1500 rpm ? , but the r56 does fly though , those rims are quite nice will look sexy on your blue meanie !, and the other steve , i thought it wa also even illegal to have a nos set up even if the bottle wasnt plugged in.

[scolburn79]

Yeah, that is why I said to hide the lines so they can't be seen.

I have the front mount i pulled out of mine that i can loan you? Its fairly small but is quite thick. You could size that up and see if it fits. Obviously it does on a R56 down lower and in front of the radiator.

Also your idea for water cooled IC is excellent. also the fitting of it is far easier depending on what space you still have under that specialised bonnet of yours. I saw a great article on water IC's and some interesting facts about immersing smaller IC's in (of all things) Parafin wax!. Its properties do not allow the temp to get above 50 degrees and because IC are heat sinks, it just sucks the heat out of the air. If you are interested in seeing the article i can dig it up and post the link.

On the NOS thing, i didn't say the dealer was sane. I know the properties that NOS can bring but its not my scene anyway. Plenty of development left in my engine before needing that.

As i said above, Nos is a bit crazy for me. Agree with you on the 1500 start. Did you have a standing start? Looking forward to seeing your Mini in the flesh. We'll have to tee your mate up with Gregg, Scolburn and others for a run through the hills.

Hey Steve, Unfortunately the Front mount for the R56 will not be any good for the R53. Their is just not enough room to get the pipes through. As the exhaust comes up on the front in the R56 it gives you that much more room to play with as it has pushed the engine towards the back in the car. The R53 is right up to the front Would be nice

I would be interested to have a closer look next time i am near a pre 56 model. The water IC looks like a goer then?
