15% on a MCSa

one more thing...
i just want to give a HUGE shout out to the fine, fine folks at prestige mini in nj. yes, i live in nyc and yes, i am proud to say that i am happy to drive an hour out of town to get the absolute best mini service i have ever encountered. after just getting off the phone with them and telling them of my plan they assured me not to worry about the warranty and scheduled service on my car. they told me that anything supercharger related will of course be my responsibility, but as far as they are concerned everything is else is still completely cool. in fact, they are totally mod friendly and see lots of pulley'd cars in their shop on a regualr basis. (not to imply in a problematic way, just that they have lots of customers who are using pulleys). anyhoo - they deserve some praise for this stance, so here it is:
you guys rule!
you guys rule!

Everything good you've read, heard or seen about a MINI Cooper S with a 15% pulley mod is true. The car really sprung to life. It pulls like mad. The power band is much more rounded and even - offering more power at lower revs - and gobs of power where there was solid power before. 2nd, 3rd and 4th are a total revelation - just a completely different car. 5th also has more power throughout its power band and pulls where it didn't use to pull before. 6th is still a highway cruiser and shows no real benefit from the upgrade. (I saved 1st for last because that gear gets wrung out really fast now - but it sounds a lot cooler!) Where the MCSa used to really come alive at, say, 3800 rpm, the car now wants to fly at 2500 rpm. It's eager. It's urgent. And it's definitely, beyond the shadow of a doubt, a lot faster. Here is what it's not: it's not a Porsche killer. It's not a first-off-the-line drag car. It's not night and day different. What it does give you is a complete range of power that will surprise you when you least expect it. Even after a three hour drive back (I took the long way!) the car would simply take-off when I hit the go pedal where it didn't used to before. I would go as far as to say that adding this much power to the car will require some modification of your driving style - at least is has for me. All in all I am 100 percent happy with the pulley mod and would say to anyone on the fence to go for it. WIth guys like Eric at Helix and Randy at Webb Motorsports having done the amount of research on it they have - not to mention literally hundreds of cars with thousands of pulley'd miles on them, this one seems like a real safe bet.
and for the record, eric at helix rules - he's a total pro and knows these cars backwards and forwards. run, don't walk...

Sounds great. For me, my challenge would be to restrain myself - the moment that I give in to the modification bug, I am on a trajectory that includes new head and cam, CAI, larger throttle body, header with high flow cat and cat-back exhaust; and then I will have to run 94+ octane. What are you running octane-wise with your mods?

Does anyone have a 15% pulley on their MCSa and run the 91 octane crap with no problems?

I bet it improves driving the car in urban situations, having the power band moved down a bit.
BTW, did you have the lower heat range spark plugs installed? I've heard it's recommended with reduction pulleys.

Just got my 06 MCSa done by Randy Webb at AMVIV and now it just feels stronger. Now I love pushing it harder on the rpms and simply pulls very hard from 5k and up. I currently have a M7 60mm throttle body, Alta larger intercooler, and Alta CAI. The car has 5k miles now and hopefully more trouble free ahead. The only trouble I have is a flat spot at around 3k to 3.5k rpm, where the car feels flat and not smooth. It pulls smooth but then it slows down a bit at 3k to 3.5k and then it picks up again. Might have to look into doing the MTH ecu tuner file to fix this. Besides the flat spot everything else is great.
I went way over my budget over the weekend at AMVIV and got a few items sitting in my truck ready to go into my MCSa. The most exciting items are a set of Willwood 12.2 BBk with cross drilled slotted rotors and a new exhaust catback system from M7. The M7 catback is not out yet but I got a lot of mods from M7 and Peter and Randy were kind enought let me get the final prototype display system they had at AMVIV.

and no, didn't get the plugs: eric at helix advised against it. as far as i am concerned, his word is gold.
