Default My Sprintex Conversion

First off , there's a big controversy on NAM about this product and I'm leaving that over there.
This is just going to be my results and my impressions.

Here's the back-story on my quest for Power. (and World Domination)

My Car:
'05 MCSC/JCW

My Mods: (current)
RMW BVH
NS2 cam
Mynes V2 header & original JCW exhaust
550cc injectors
Byteronik Full Acess software
7800 rpm redline
Stock internals except for ARP rod bolts
Current milage 178,000

The Cars History:
Last time on a dyno was spring 2010
With the M45 & the JCW pulley, RMW shorty header and a bad O2 sensor (don't ask it's just the way it was).
The best we could achive was 232whp. (I feel that this number was a little low because if the trouble we had tuning with the bad O2 sensor and historically from day 1 my car has always dyno'd low)

The Sprintex Project:
The W/P gears on my M45 had been making noise for a long while now, I was hoping to make it till spring 2012, I was going to buy a new car so that I could then do a complete performance rebuild on the Mini including the Sprintex. Well it didn't make it, so I'm doing the Sprintex now.

The Sprintex comes from the factory as a bolt on kit w/ a 70mm pulley that is supposed to create 15+ psi of boost, it also has two other pulley sizes that you can purchase seperately. (the 64mm 18+psi and 60mm 19+psi, both of these WILL VOID the sprintex warranty) I purchased my kit with the addition of the 64mm pulley.

There has been some controversy over the use of the 64mm pulley on a stock lower end motor. (I'm not going into that here, if you're courious see the NAM thread) Some have worked out and some haven't, so untill that is better sorted out and because I still have to drive the car everyday, I've elected to do the install with the 70mm pulley for now.

In a perfect world I could have gotten some "beginning" numbers, but since the W/P gears went on me I was unable to do so, all I can tell you is that my "Butt Dyno" tells me that the car was running as good, and probably better than back when the last dyno was done.

I'm doing all the work myself, in my driveway, and squeezing it into my 70hr work week, so this is def. not a one day project for ME, but so far everything looks really straight forward and if you have all your supplies around, you could def. do this in a long day or w/e.

At this time the car is completely tore down & ready for the install, I'm waiting on one part, that I will get on Mon. afternoon,(damn UPS, see neg. energy thread) and will start the install then. (Had my Intake Manifold match ported for my head.)

Anyway, thats where I'm at, I'm going to do the S/C pre-assembly tomorrow, and I'll start taking some pic's as things progress, I'll do my best to answer any questions but don't forget I'm just an opionated amateur, so take it for what its worth.

The only thing I've never done as far as cars go, is internals (rings, bearings & such) I felt like I wasn't maticulous enough, but si far, with the help of the instructions (you can just download them from the sprintex site) it's been fairly simple, I haven't even had to crack open the Bentley.

Although on second thought, where's the "knock on wood" or "fingers crossed" smiley.

The ONLY thing that i find off putting about the sprintex is that you have to relocate the knock sensor. That being said, i havent done a crazy amount of research on how this is ok or not. I am pumped about the kit though. Seems really awesome

Looking forward to you updates and seeing how this all works out. It may be a possibility for me when I need to replace my sc again.

Wow, I'm seeing some familliar names around here, I might need to log on to M/U more often. I am also following this swap on the other sites, looks so far like the M/U croud is more open to the idea of an alternate S/C without the *** name on it than NAM is.

Sorry couldnt answer my phone, crazy hectic day.

You've got my #, just call when you can.

As for today not much happened, intake didn't arrive until too late for me to pick it up, got all my preliminary bolt togethers done on rhe S/C, the real fun starts tomorrow.

I'll take some pic's as it goes together.

I guess I got beat to the punch by someone as to the first BVH / Sprintex combo though

Picked up my intake and some bonding compound for my core support today.(it was broken in a few spots due to an encounter with something a few years ago)

Here's where I started today.

Two hours later.

Click the image to open in full size.

The S/C is only temporarily mounted, the I/C horn hits my engine damper bracket, (it was designed for stock), and I'm having some issues with the bottom S/C mounting bolt, it doesn't want to go in all the way, I think it just goes in a little farther than the stock one and the threads just need cleaning up, I'm picking up a tap and shorter bolt in the afternoon to cover all the bases. Also going to modify my damper bracket @ a friends shop on the way home.

So far except for the bolt thing everyrhing installation wise is fairly straight forward.

Was only able to put in about 2 hrs today, re-mounted my engine damper bracket & such, then installed the S/C, tensioner, belt, alt., dipstick tube, knock sensor and Bypass/Intake horn. (anyone else who does this there are two things to point out: 1. The bolts in the tensioner tool are only there as fulcrums, they do not fit into any if the slots or holes for leverage or to secure the bar. 2. When installing the dipstick tube, install the S/C bolt first and make sure that it is threading correctly before you do the block bolt.)

W/P and most everything else should go on tomorrow, up to the point of the core support, I'm going to stop at that point so that I can do my axle boot repair while I have all that extra access to it.
Hope to be completely done by Sat.
