They are not a waste of money and yes I have one. Find someone in your area that has one and you can see for yourself. Changing driving habits does not affect the gas pedal response as it is controlled by the ECU not your foot. But hey this is just my opinion.

 

Detroit tuned, oh they are in Miami obviously

I have driven a mini with the d1. All it does is make it so you don't have to change your pedal habits. The main reason it is installed is for people who don't change there pedal habit and don't want there usual throttle position choice to mean almost stalling the car at starts. There is no power gain plus it just gets in the way when you do buy something like the bytetronik and log runs for tuning. I believe it is a waste of money you may feel differently but why pay money for something I can remedy with my right foot.

 

Nothing but your opinion just like mine. But it is a fact it changes the response time on the gas pedal and it reacts quicker to your foot.

Nobody ever claims it does.
If you dont want one, dont buy it. Yes a tuner like JAN can change the throttle maps to react faster. Funny how they even have a sport button on the newer MINI's to do exactly what the SB or D1 spec do.

 

Again check these out

Id rather spend the money on a cam. and actually work twords building power than ego.

 

Nowhere does it say increases power.

 

No argument there. But how about knowing when you hit the gas the pedal it responds faster and the power from your cam is felt sooner.

 

Gettin a cam.. Do you need to upgrade the springs?

 

CRAZY E started this thread and, while I don't want to come off as an "Old Fart", I need to suggest that the best money spent to go faster and have good, safe fun in your MINI would be to start going to well-run driver's schools rather than street racing or trying to prove how fast your car is vs. another's. I've been a DE instructor for over 30 years and I've had a lot of people as students who thought they knew how to drive learn just how much they don't know. Learn how to drive a road course well, then you'll find out that it's all about smoothness, consistency and balance. Improve your suspension, learn to go faster; improve your brakes, learn to go faster; improve your engine, learn to go faster; then start all over. "You just can't eat an elephant in one bite". There's yet another aspect to doing it right: We really don't want to give MINI drivers a bad name...and we really don't want to read about MINI fatalities.

 

Agreed.

 

A cam is a serious performance upgrade and no you don't need new springs just don't go too aggressive on the cam as the more aggressive ones may require tuning. I just have a hard time believing an add on will make the pedal "faster" and after driving with the d1 I just need to give my car slightly more throttle than normal to emulate one. The car will give you the throttle you demand all these in my opinion all these snake oil fixes do is turn your 15% throttle input into 25% I would say these devices are like the plasma booster and coils as being advertised as performance upgrades.

 

But it would require bigger injectors correct?? To what size would you think would be good?? And of course would most likely need a tune after all is done?? Like I said in an earlier post some injector upgrades say stock can only handle up to 240 hp well I'm at around 220 to the motor so a cam upgrade aswell as a header and highflow cat.. Will require bigger injectors? I have all sorts of suspension work done already. Aswell as a brake upgrade so I won't be losing drivability! The sprint booster will just be a "why not" thing where id like to try it.

 

That will depend on the cam but if you really want to do things right save up for a big valve head with a matching cam and you will then have to choose if you want to be jan fan or use bytetroniks for tuning because these tuners like to use different sized injectors. Without a tune 380cc is the biggest injector you can run and that's assuming you have the JCW software. I know because I was getting occasional lean codes with the JCW software on the stock 340cc injectors so I got 400cc injectors but immediately got rich codes and this continued until I got the bytetroniks full access with the 550cc injectors.

 

FWIW:
I was dynoed at 203.1 in my 2006 R53, that was prior to adding the ATI super damper with the 2% overdrive (from WMW). I have done the following and for the most part in this order:
Alta pulley package 15% with belt, coil pack, & plugs.
Borla street cat back exhaust
Alta header
Craven CAI
Alta front feed intercooler
JCW 380 injectors
WMW tune at AMVIV

The first three made the biggest performance change some of the later were not noticed at all.

Suspension changes include Koni yellow, H&R springs, Alta rear sway bar, Powerflex motor mounts.
Soon to add: Zimmerman F/R rotors, EBC pads, SS brake lines, Hotchkis rear lower control arm, NM rear end links and many Powerflex front suspension bushings.

The knowledge gained from the NAM site has been amazing also, Way at WMW will not steer you wrong and will politely tell you when you are about to waste $$. I always listen to Way and I do appreciate and trust his input, being from Philly, I do not always listen.
Also, I have the Sprint Booster (no increase in HP) which is a BLAST, the car Jumps off the line and revs up quickly. it is fun but takes some time to get used to in stop and go traffic, luckily in eastern WA there is no such thing as stop /go, just open roads and twisty farm & mountain roads.
Again, FWIW.
