Here are my data:
-02 cooper S, mileage 60000
205/40 17 Yokohama Parada
- Shrick cam
- "noname" water to air intercooler
- "noname" 19% pulley
- "noname" custom head with original valves
- "noname" big throttle body (63mm)
- OBX header+header wraps
- no cat
- One ball with custom 2,5" stainless steal pipe to back resonator with magnaflow middle
- denso iridium IK22
- K&N panel filter with modifed airbox
- calibrate bypass valve
- fidanza flywheel
- aquamist water injection
- MTH chip (but it's very old and it's write only for the pulley
I think that's all.
The temperature was 17°C. For each graph we do 2 measurment.
This is independent measurment of power on MAHA LPS2000 dyno. The power is with EWG standard which is more accurate than DIN but lower number. At DIN standard power will be bigger for approx 3%.
Here is without water injection, the water in intercooler was hot because the car was there for about 30min without fan. Maybe it will be a little more gain with cold water.
This is with just water in water injection. The water injection is not necessary with good intercooler!!! Gains about 15 HP are dreams. Only with custom chip maybe you get something.
This is 30% methanol in water injection. It's bigger power but the curve is deformate like with just water.
Now I start with water injection at about 4000rpm, but I will start now at 5000 in the future but only in summer.
Does gearbox (pre of post facelift) influence to power? Do you measure it in 4 th (I am looking only 116mph at 7000?!?!?) or 5th gear?
