I did some testing (on an S, please forgive me) of TBs and found no added power, and some drivability issues with the largest one I tried. But that was on a car with a stock head. When I spoke with others about TBs, it seems you won't get much from them until you really open the car's breathing up. Dinan says that the TB makes HP in his kit, but I think it's only in the top of the line kit for the S.

As for the Cooper, I don't know if it will give HP or not without other mods in place, sorry, just no experience. But I am curious if any of you that have installed them get a flat spot at about 3000 RPMs..... Let me know if you have.....

That was quick - thanks.....but you kept the wrong one (the last post was the complete one).....oh well, I think Dr Obnxs covered most of the rest of what I typed anyway.

 

I don't have any data, but I don't feel a flat spot. I seem to remember folks talking about a flat spot with M7's first TB for the S, but then they came out with a slightly less bored out version that was better. I'm not sure of all the differences between M7's non-S v1 and v2 TBs, but the v2 is only 58mm.....maybe that's why no flat spot?

 

that can effect the drive by wire..... Count your lucky stars that the intake tract on the Cooper is so much cleaner.
I've found my flat spot first showed up with a 63mm TB, but went away with a 60mm... for a while. More mods and it came back. Ghosts in the (ECU) machine....

Anyway, thanks for the answers...

When I install the throttle body, I'll ask MTH for an update.
A friend of my with a Cooper has installed the throttle body and is very sitisfied. It gives more respons at the throttle pedal.


What is th difference between v1 and v2?

 

differ in that the V2 has a thinned shaft. The V1 just is larger diameter.

Also, the new Mini has a "Sport" button in it. When actuated, it remaps the drive by wire to make the opening more responsive.

If the drive by wire control loop parameters are adaptive, then the ecu would "learn" about the change in flow rates and tune the more aggressive response out... Don't know if they are in the Mini or not....

So is there any news on this? I've got almost 11 months....

 

OK, I will give it 30 more days, but after that....

 

that makes me curious.. are we talking a bolt on or something internal?

 

trust me, it'll be 30 days max......
the real question is which 30 days.

 

I think this mystery product will fall under the same category as the Santa. Nothing but a myth.

 

HI Jerry....

I'm sad to tell there's absolutly no interests in tuning the Cooper.
If I get 2 calls a month about tuning the Cooper I would be blown away.

People are talking up storm about the meager offerings for their car
but ultimatly they never call or buy anything. So because of that I have
put this particular product on ice, as R&D cost is very high and I sell everything I can Make for the MCS.

Hey peter,
I would call but I have no idea what to ask for. Nor do I have anyideas for a product that I would like to be made. do you have some things in mind to make the cooper faster?

^x2

Some of us are not mechanically inclined enough to actually ask for stuff. But if we see a product that might work, or that we like, we buy it. Like the USS. I would have never thought of it. But when I saw it, it made sense and I bought it. By the way, mine is still hitting my cat.

 

are as old as the first engine. There aren't really any secrets, it comes down to more air and gas lit at higher compression makes more power. While it sounds simple, in practice getting more power out of a highly tuned motor isn't ever easy, and might even be considered an art form.

The basic idea is to improve flow in and out of the combustion chamber more efficiently will allow the motor to make more power. This brings us to the largest flow bottle neck on the Mini motor, the exhaust valves. But this means head work and that's pretty serious stuff (but I have to say, it was much easier than I thought it would be. It's a one day job, two if you go very slow like I did). Other basic principles of improved flow is smooth flow, and this is where porting and polishing stuff comes in. If you're a good home mechanic, improving things around your intake ports can be done pretty easily, but to get the best, you need to be good, and that means sending the parts out. The idea behind this is that stuff for stock cars can have more slop in the fitment and it will be OK (precision costs in manufacturing and drives prices up). So you both open up and match parts.
In the area of bolt ons, improved filters, and intake parts can help. Same with headers and cat-back exhausts. The sad thing is that a lot of the bolt ons have a high $/hp ratio, and they may only shine when lots of mods are there as well!

So what to do? Start by reading. Check out Amazon and look for a book or two on engine tuning and modifications. Then read the threads where people talk about what they've done (someone here did put a ported head on his Cooper, and had great results), and after you've read the books you bought yourself for your particular holliday , you'll be much better able to evaluate what you read, I guess with a more accurate BS meter!

In the area of basic bolt ons, you can do filter, intake, TB, Cat-back, header, crank pulley, underdrive accessory pullies.
Deeper bolt ons would be lightened flywheel, LSD, and improved clutch.
Stuff that you'd have to send out for, or buy extras and get them modified would be intake porting and polishing, and head work. If you do the head work, have your intake done at the same time so that you can get a really, really good match.
To really blow the wallet, get a stroker motor built, with increased displacement, custom pistons, head and intake work. Add a turbo while you're at it! (and a tranny to take the power....)

There's a saying in hot rodding. It's not how fast you CAN go, it's how fast you can AFFORD to go!

Have fun! Make it faster! And don't forget the suspension. And the best mod of all, driver training!

Well, I've bought a MiniMania Intake, a Bluefin, Magnecor wires and NGK Iridium plugs,
and am going to buy a Milltek exhaust this spring, in the name of MC (non-S) performance.
If I had more money, I'd seriously consider a header and a performance head,
possibly with a street cam, especially if I knew someone who was making them
with a non-aspirated engine in mind.
I've also done significant suspension, lighting, minor bling, and comfort tuning.

If you had something in the
"And please don't kill me for saying, that this thing is
incredible, and you will put it on your "Santa Clause List"
category, I would most likely be very interested, and I think many others
would be as well. I have to admit I'm unlikely to call about a mystery
product that doesn't exist, without a clue to what it is(n't yet, and now,
apparently won't ever be).
Suit yourself.

 

 

Didn't we (the forum) already go through this at least once?

vendor: we're working on a performance upgrade for the Cooper

forum: we're excited, let us know when it's done!

vendor: silence

forum: what happened?

vendor: we canned it because there's no interest and nobody called to order our mystery part.

forum: that's crazy

I'm sure we've been through this before...

 

We might have new members that have missed the previous...uhm... what would you call that?

 

Oh, we have, and not just with one vendor either.

The cooper market is definitely underappreciated. I'm not saying the MC tuning market is as vast as the MCS tuning market, but then again ever tuner and their brother has a range of products for the MCS. The MC market completely lacks competition and seems ripe for someone who wants to really be a champion for MC tuning to step up.

Why are vendor's surprised when they don't have a product for the MC and they don't get calls for it from Cooper owners? I don't call Crate and Barrel to tell them I want to buy furniture from them that isn't in their catalog or in their online store. I don't call J. Crew or Banana Republic to ask them to make shirts for me that aren't in their catalog or in their online store. I look at what is available in the market and make purchase decisions based on what products are actually being made and available to buy. Call me crazy for doing that, but that's just how I roll.

 

...........I as a MC owner feel abandoned sometimes.

 

What kind of products would everyone like to see?

It does seem rather limited what we can do to our cars...

Maybe the next Gen Coopers a different story?

 

Something that makes an improvement in torque and/or hp.

 

make promises you can't keep. I garantee if you actually made someting for our coopers that truely increased hp or torque, people would buy it...I'm thinking you tried and failed. I'm being curse..but no more than your post. I'd suggest you go to local community college and take a marketing class and class on customer service. Would do your business good.

Peace

 

But really what is there left to do?

On the market we have intakes, throttle bodies, heads, cams, headers exhausts blah blah blah... I mean thats why this forum has gone a little stale... not enough to talk about... well maybe turbos but big big dollas...

But you know what would make big money, up rated trannys for us 02-04 owners. With the rate of tranny failures, huge market!!! Better alternative then getting another BMW time bomb or Mini Mania UK up rated tranny which you have to order across the pond. If we have a vendor that can provide the tranny here in North America, anything goes wrong, there wouldn't be much of a problem for the vendor to up hold they're warranty due to distance. Peace of mind.

Just my thoughts...

Thanks!

Randy
