Its been over Year now since i placed my order for my Active Stage 2 sc. I put the Sc kit on with about 43,000 miles on the car and was averaging about 15.8 mpg highway/city driving.
performance mods on my car at the time.
Fabspeed High flow cats
Fabspeed x-pipe with resonators
Fabspeed Maxflo exhaust.
Ms Scoops
Bmc Air filter
Pc tune.
The Car N/A was amazing felt good on the track and fast in a straight line. But a fellow Friend, many will know him as LostMarine would beat my ass with his RB setup 335i. So I ordered my kit and had it installed by Maximum Psi in New Jersey.My delta for the kit was 140-150 hp gain and 88-91 Tq gains ( picking the highest and Lowest dynos). These gains are with the mods stated above plus active sc.
Performance Mods on my car now:
Fabspeed x-pipe with resonators
Turner Catless.
Active Autowerke Sig Exhaust
Active Green filter
Ms Scoops
Stoptech BBK
After 21,000+ miles with the SC the car is running stronger than ever. I am averaging about 18.6 mpg Highway/ city driving with pushing it and driving like I did before the sc. I have been able to put some nice beat downs on some nice cars that would never expect a four door to beat them. At track (road courses) the car is amazing but at times i will have to ease in the pedal compared to mashing the pedal coming out of turns(when i was FBO). At Pocono i was able to hit 165 in the straight away but i had to brake hard in the braking zone.At the Drag strip the car ran on street tires an ET of 11.2.
I only have issues with having the Active Sc is going through tires and gas faster because i always want to be in boost and hear the beautiful bov's. lol A problem that I encountered by Maximum psi was they left a stock bracket in that held some stock lines. When i was at Pocono Raceway my AC belt got ripped but by the bracket becoming loose due to the G's i was pulling in the turn and had a cel come up. A charge malfunction showed up and my battery wasn't charging because the belt was starting to rip up or was completely gone.
this is the bracket
what was left of the belt.
The best thing about it was i went to my local Napa store and got my replacement belt. Then had my local bmw dealership install it, and also do a leak down test and compression test done. I wanted to see how my engine was after 6X,XXX thousand miles and 21,000+ plus miles of being sced and abused. Both test came back 100 percent perfect, a healthy engine.
When ever i have had a question or thought i had a problem Karl, Rob and the rest of the Active team have always been their to help. I have never met or dealt with a company that cares for its customers and is always willing to help. Hope people on the fence about getting a SuperCharger it helps make life a little easier. It can be with any company you like but i just recommend AA because of my personal experience.
some recent pics of the car.
