Dyno and Track Results

There have been more than a few people asking about what bhp and torque figures different Mini2 cars are generating with their various tuner or homegrown conversions so I thought I'd start a thread where Mini2'ers who've had conversions done can post dyno runs proving their power in the hope the administrators deem it worthy to be a sticky.

I'll start but could everyone also include their car details as below:

Gen: R53
Model: Cooper S
DOB: Jan 2003
Wheel/tyre size: 215/45/17
Mileage: 42k
Tuner: Lohen/1320autos

Engine Modifications:

Alta 17% Pulley V2
Reduced Supercharger Belt
GRS Intercooler
Janspeed Manifold with High Flow Cat
Milltek Cat Back Exhaust
Alta V2 CAI

Dyno:

1320 Autos

Peak BHP: 242.6
Peak Torque: 186.1

With just an intake, 15 pulley, manifold and exhaust I ran 15.0 all day in 25 degree heat....stock everything else with terrible starts and 60foot times No LSD!

I think your big issue like I said is the manifold and maybe cooling the charge air (so an intercooler upgrade needed)

yeah the S works and a GP works were getting 15.1's so its not much but it put a grin on my face!!!!!!

yeah i'm getting an intercooler and spray set from gtt at the end of jan

along with a few other little tricks
then i'm gonna aim to get bigger injectors and a remap in february
i'd like to push 250bhp-ish
then later in the year im getting a new manifold and exhaust with larger cat :biggrin:

p.s. my 60ft times were around 2.5 seconds!!! :-(

yeah i know!! end of the day, every car looses money, if i spent 21k on a works in 4 years it'd be looking @ 10 k if i sell it! but when i get the next car i wont be moving from it for a good few years so it doesn't matter, i'd jus like the buzz of getting a brand spanker car, that only i have driven! shame a wasted my £800 on the new IC and TB the other week! lol

p.s. i have paid for my mini to be sorted, so i'll be part exing that.

Seeing the big hitters results from a recent RR day printed in Modern Mini made me realise how good my results from nearley 2 years ago were!

Lucky Dave with;

243.5 bhp @ 6856
205.3 ft lb @ 5413

Which put my BHP as a quality 4th and torque comparable with Bigshows in 2nd position :eek:

Im shocked :aargh:

Bert hasn't though?! Maybe he can be made to recreate the glory days of LDs grey S, if he ever gets time to put him back together!

Gen: R53? or 50? (163bhp)
Model: Cooper S
DOB: Sept 2003
Tyre size: 205/45/17
Mileage: 61k
Dyno: Motorscope, Northallerton
Tyre pressure: 33psi
Temp 22.3 Deg C

Max Power Wheels: 155 bhp
Max Power Engine: 198 bhp @7024 rpm
Max Torque: 165 lbft @ 4273 rpm

Modifications:

OMP back box
Pipercross filter & alloy heatshield from R5 GT Turbo (doubt this does any favours due to heat soak)

I was very surprised at these readings, however, I did think it had a different pulley from day I first drove it! Much quicker than the other two I test drove.

I guess this just about confirms it's got a 15% pulley. It had a K&N badge on rocker cover so thought it might have been tweaked but the dealer I got it from must have taken the filter off.

Will try to scan the power graph tomorrow.

Pretty chuffed, was just about to book it in for a pulley change but thought it'd be nice to have before and after power runs ... good job I did!

I don't know, but after looking all the dynos here, i think my car does has a very slow bhp with all the mods i do have...isnt it? I thought my car would have between 220 and 230bhp, is that because i still have the stock ECU and didn't re-tune? or why then?

Please if some of you could answer me i would be very pleasant ;)

Dyno Results

Bought a 2005 Mini S with JCW engine/brakes and took it round Brands Hatch :D

Since then I've added a GTT induction kit and a Milltek manifold and sports cat. Paramount Performance did an ECU map and the dyno run shows a healthy 222 bhp (though this was done on a cold day which may have helped a little). Haven't been back on the track yet but the engine seems to spin up a little faster and there feels to be more torque.
