Wow, just took a look at this thread. Awesome stuff. A great alternative to the turbo kits and one would imagine this would be much more reliable as well. That's guys for keeping us posted on this!!!

Since it uses our beloved trinitc 1.6L and will come with a 250hp version from the Factory. Doesnt say if it will be a Turbo or SC but something to think about if it is the M42 SC and then Rob gets his hands on it and Adds the M62.
Also there is the 828 version that has the motors as well. and with these cars wieghing in at 1600 lbs for the 012 and 1300 for the 828. i would say they should be rockets in a straight line. I cant wait for a test drive to see handeling

Thanks for the warm welcome guys! So far, I've been super pleased with the caliber of members this board has to offer. You guys really do represent your community well.
Again, it's hard to put a psi limit on something like this. 20psi isn't what kills a motor. You do far more damage with higher revs than you do with cylinder pressure (provided you aren't detonating). In my experience, what kills pistons is temperature or detonation. The few I've seen go were the result of a Nitrous marathon, a fuel pump failure (followed by a 20 min. track session 
) , and just general running lean or over heating.
Something else that is important to note is the Eaton blower is exceptionally sensitive to the pressure differential between the inlet and outlet. You'll notice on the charts that it is much happier at lower boost levels because the higher the boost, the more hp it takes to drive the blower, the more the temperature climbs, etc. The more mods you do to your mini to "lower boost" the better the kit will perform. Big exhausts, cams, head work, low restriction intakes (reduce vacuum at inlet), all contribute to a more favorable Delta P at the blower and end up in more power at the wheels.

Can't wait to here more - hope my AGS 3 will still fit - but doubt it.

Going further off-topic...
there's a guy in Woodside who is converting Ariel Atoms to all-electric! For the sports car crowd no less. I think I saw one (red highlights) on San Hill Rd......
And this 62 replacement looks very, very interesting!

Great to see BRP digging into the MINI world! I met Brant a few years back at the Miata's on the Dragon, great guy that knows his stuff. I wish them the best of luck with a big-blower MINI product

Welcome, I spoke with Brant earlier today and I am very excited about the project.....
this is very cool.......

Along the lines of forced induction...
I've seen a turbo kits mentioned more than once in here. Personally, I'd prefer a turbo to a super mainly for the efficiency reason.
Are the turbo kits specifically for the naturally aspirated or supercharged engines?
I'd love to build a turbo Mini, but would prefer the 6-speed Getrag transaxle. Would the better path be to start with a base Mini and swap the 5-speed for the Getrag? Or is the better path to replace the SC with a TC on the S Mini?
Can a supercharger be safely/reliably clutched to provide an on/off switch essentially giving you the choice between economy and performance modes? I can understand it probably wouldn't be good to switch it on and off under load, but that wouldn't be a problem for me.
I think I've seen turbochargers with intercoolers before. If the supercharger was swapped for a turbo, could the intercooler be reused?
Just a few thoughts.

Rob, we're glad the you've dedicated the time and resources to make this happen for us! Curious, what made you get involved with the MINI?
We are a very passionate bunch here, with home-grown tuners, and wannabes like myself doing all that we can to contribute to make this car even more fun.
Looking forward to when you are officially a vendor so you can elaborate further. Thanks much.

Intercooler is an intercooler. Change the plumbing and you're good. But I'm betting getting one properly sized with nice round inlet/outlet flanges would be cheaper than paying someone to mod the stock unit.

I just spoke with Dave, and he's doing final checks on everything before firing it up and going out for a drive. He'll be checking and making adjustments to the A/F ratio...AND THEN OFF TO THE DYNO! (hopefully) I'll hear from him again later tonight and have some more pics to post.
Everyone stay excited, this project is very near completion ; )
