The Mini had a chance to get on the dyno this past weekend. According to the reports, it has 190hp / 182 torque.



Mods (that I know of) -15% pulley, Invidia exhaust, Alta CAI.

 

What brand dyno?

Rule of thump is f you increase the boost by 15 PSI you double the HP of an engine. You added around 5 PSI so 5/15 = .33. You do not mention the year but at 161 HP of the early models, and as you increased boost by 33%, the result would be around 214 HP. Talking at the crank, not the wheel.

 

Mine is an 06 (October) MCS. The dyno was a Dynojet on a trailer (if I had to make a guess, the 224 model (2wd)).

 

With a loss factor of 85%, the 214 crank HP equates to around 181 whp. There are three dynos that are around. The dynojet and the mustang use a system where the wheels are left in place where the dynapack removes the rear wheels and the hubs attach to the pods.

The numbers will vary so what is more important IMO is having a baseline performed before you do any mods.

Back to the pulley, that extra 5 lbs of boost compared to the cost of pulley is why most will say it is the best bang for buck.

 

The mods were on before I got the car. Using factory specs, it came with a 168 hp motor (at the crank).

 

For years the going dyno number with the 15% Pulley, CAI and maybe exhaust, was around 200 HP at the wheels. As mentioned above it some what varies depending on Dyno Brand... If your already at 190 HP and the car has not been tuned you may get more then that...

 

As a frame of reference I had my R52 factory JCW on a dynojet on a hot August day in south Florida. I got 183 at the wheels and the AFR was in the high 10's if I remember correctly.
