Drivetrain M7 "device" available

Keep it there and it builds to 10. I have yet to reach my max of 11.5 with the device. Also, if I were to give an impression, it seems a little skittish. What I mean is that boost fades as quickly as it rises.
I have noticed that some may remove the intercooler to install this device. This is a simple operation. Take note of the clamp positions before you remove them. Even better, lay them out on a table as you remove them to insure the proper refit. It will make your life easier. Additionally, make sure that the intercooler ends are clean and clean the oil off of the inside of the boots. Make sure that the boot is fitted properly. Run your finger all of the way underneath on both sides to ensure that the boot is not folded or crimped. The boots will slip and/or leak if not properly installed or if they are dirty especially under hard driving or with the higher boost pulleys. If they do leak you may generate a code in the computer and even if you refit them properly the code may not go away. I have seen this on two different cars. You also may NOT generate a code but the car will not idle. I once had to force a code by disconnecting the throttle body in order to have a code to clear. Additionally, I have not been successful clearing these codes without using ODBII software. It only takes a minute but if you don't have the software and cable you are SOL. Good luck.
Thank you
Blue MCS thank you for such a well detailed intercooler removal and re-install post. After you do it enough times it is easy to forget the fine points. You covered them all as far as I can tell , thank you!

Thanks Randy/Peter
I've got it installed and guess what? It does seem to respond better to throttle input. I haven't taken her out on the road yet...can't wait
I find it easier to install with the driver side rear incooler mount removed (after the incooler is removed, of course). I left that off after the install as my Alta TMIC had no use for it.

Regarding the dot...
The first run of tubes that went out we used whiteout...big mistake
Anyway the tube has a bump where the valve (restrictor) is, the shorter
side (path) should have the dot. If you have any further questions just call me.

Gas mileage with the "device"
I have had the "device" now for about 3 tanks of gas and so far no real difference in gas mileage from pre-device. Low 20's in town and 28-32 mpg on couple of long highway trips.

Is this the end of the freeby? How's the mirror coming

Thanks, M7! The device is simply terrific. I can pull away now with absolutely no hesitation. I thought the 15% pulley improved it a heck of alot, but this really completes the job. :smile:

, theres no way in hell I could prevent myself from spilling the beans though, I always talk about how good one thing or the other feels after an upgrade.
pretty soon.....

Thoughts? And Thanks!
sfjames - assuming this is the only mod you've done to your car I'd like to know your thoughts so far. Please, share.
Randy, received "the device" in yesterday's mail. Thanks! Apparently, it went all the way from Lakewood to Cerritos in just under 24 hrs. Thanks again, AMPR

hello AMPR, since I put the device on my MINI it pulls harder when floored. I can hear the supercharger working earlier than I think it used too. Its more driveable between 2000 and 3000 rpm range, I don't feel I need to downshift as much as I used to when cruising. I think it would benefit someone with a pulley even more in the lower rpm range. I've been waiting for Andy from Ross-tech to get one and post some numbers, we'll see what happens there. My MINI btw has a Alta intake w/intake hose, Alta oil catch can, Alta intercooler diverter/sprayer, Borla race exhaust and now the ol M7 Device to. Next will be rear sway bar.
and I'm plotting on a pulley, 15%. take care.

Hmmmm. This makes no sense.

Since I don't have a MCS to experiment, and only have Physics to back me up.
There is no reason for a restriction in the vacuum tube to the bypass valve to change the operation of the engine when cruising at a constant engine RPM.
I think many of these effects are "Placebo" which is a great effect, don't get me wrong, but not measurable or reproducible across other owners.

control-panel, and not be bothered by my posts. Please don't post asking me not to comment when you have control yourself. Thanks. That will keep the thread related to this modification, and not related to me being an *** and a skeptic all the time.)
Trippy,
I also tend to be a bit of a sceptic, but last night I took the plunge and installed "the device." This morning I took my MCS for a short drive, then for a longer drive this afternoon. I would have to agree with SFJames in that it does seem slightly more responsive. I can't tell you why, but it does.
Maybe it's as a result of an increase in vacuum, or it could be a byproduct of Bernouli's law since the device could be acting as some form of venturi. I don't know, but it does seem more responsive.

Hi trippy...
Thanks for telling us the obvious.....no effect when cruising...
But Oh so sweet when jumping on the throttle when need be

"There is no reason for a restriction in the vacuum tube to the bypass valve to change the operation of the engine when cruising at a constant engine RPM."
Agreed 100 % but we have only made a improvement in throttle response we were not looking to assist in the cruising area.
"I think many of these effects are "Placebo" which is a great effect, don't get me wrong, but not measurable or reproducible across other owners."
The last time i looked the term Placebo could not be applied to something that can be shown VISUALLY . I don't mean you can feel better response ( you can and many have ) but I can SHOW you visually.As for " other owners " there are already several posts on this board as well as other mini related sites that disagree with you . These are actual owners with real cars not slide rules and calculators. Again I offer a real time demo to anyone , even you number guys and you know who you are, anytime you want anywhere in the so cal area. Trippy if you can find anyone that believes you anywhere from Santa Barbara to Orange County I will meet them and show them the proof. Not theories, hypothesis, black magic charts and graphs . have a great weekend.

Interesting events.
Interesting about how both Peter and maxmini let sfjames2's post sit for 24 hours with information that they think is incorrect, but which favors the modification.
Then, after I post, they both agree with me on the idea that the mod will not change the cruising behaviour of the car.
If you guys would simply reply and try and correct misinformation about the mod instead of letting misinforming posts that favor the device lie around, it would help everyone in the MINI community get more trust in your gang.
