Arrow 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

Here's a dyno plot showing A/F ratio that I had done last week after fitting a -15% pulley. As can be seen from the plot A/F ratio remains very rich even after the addition of a pulley (stock map).

The stock intercooler heat soaked very quickly, however, the dyno operator conducted all tests with the bonnet up resulting in no forced air convection through the intercooler core. Personally I think the bonnet should have been closed, can someone shed some light on the correct way for testing cars fitted with a TMIC?

Dyno and Track Results

OK, we have a new idea that I think will work well (Thanks to MINIAC) on posting dyno and track information. I have seen a few complaints of information being posted in other threads and thus lost in the depths. This thread will be a sticky that you can post your results in and then link to them when you want to offer it up in a thread.

Posts would include:
  • Model
  • Build Date
  • Mileage
  • Engine Modifications
  • Tire Size
  • Dynometer Type
  • Maxium Power (bhp or whp) at RPM
  • Maximum Torque (lb-ft) at RPM
  • Dyno Graph (attachments)

Please only post results in this thread. Any chatter will be removed as I want to keep this as clean as possible. If you need or want something else in there, please let me know via PM. Thanks.

SRR figures


As Snowie has been asking for some SRR figures I thought I would post mine up to start off


269.5bhp@7500rpm (graph shows some clipping above 6500)
215lbs/ft@4800rpm (could be a bit more though from looking at the graph as it is nearly on the next line up which is 218.75)

From reading another thread it seems that some people want to cap the rpm limit as that can "fudge numbers". A vendor also said "I tend to ignore bhp numbers once the torque has fallen below about 15% ish of max torque,it is far less useful power and only derived due the rpm" so when you look at my graph you can see that my peak bhp figure is at 7500 and my peak torque is at about 4800 an I still make 192.5@ the redline (so that is around 11/12% ish of max torque)

I only make 2.7bhp from 7000 to 7500

So I think it is fair to say that my car is set up to run higher rpm limit period. Not just to bump up the peak bhp figure as some might think

The wheel horsepower for my car using my measured run down losses from 1320's dyno means that it is 233.5WHP (269.5bhp)
