I hope this info saves a lot of people time and money.
For as long as i can remember my car has been very sluggish from down low until over 3000rpm. Bad to the point that i didn't use the AC unless i really needed to because of how week my car felt, especially on hot days.
I've had my 03 MCS since brand new. My car is 99% stock except for a Mini Mania crank pulley that was installed to replace a degrading original heavy balancer.
I have over 80000 miles so i assumed the engine was just worn out. I never really worried about the loss of power because i didn't want to start modding the car and risk hurting an already "weakening" engine.
NOT SO!!!!!
I was at my local shop, Presicion Autowerks, and Luis said change the bypass valve, your loosing boost.
I said, ok that's got to help a little.
What i felt after driving the car with a new stock bypass valve is inexplicable with words, however if I had to explain it i would say.....
My car FREAKIN FLIES like a MUTHA FU.............You son of a b***h.
Not only the power, but my fuel economy went up like 40 miles for the tank, and of-course I'm flooring it whenever its safely possible now.
The difference is so dramatic that I feel everyone should know about this.
I cant imagine how many people are spending alot of money to mod their cars, yet with something so basic as a bypass valve, leaking just a little, its almost entirely negating the natural power of the engine.
I am here by obligating everyone that reads this post to go and have their bypass valves checked or replaced for your own good.
Don't do another mod unless you are absolutely sure you are not loosing boost from your bypass valve.
The valve i had installed is a OEM MINI valve. Nothing else.
I hope to hear some good results from others soon.
Safe Motoring.
