This is exactly what I thought it did. Some relays and whatnot will do the same. Or you could change the throttle position via some quick tuning. $300 is not worth it It's the same power curve and same exact power. Just shifted an unmeasurable amount to the left. I hope I'm not being too harsh in my posts, but the people selling these things are feeding on the uninformed and making bank from it. I've rebuilt MANY cars in my life and tried my hand at some VERY simple tuning. And if you can access a tuner, you should be able to play with the Throttle positioning sensor...

This product is the technological equivalent of tightening up the throttle cable on an older car... nothing more.

And the tags keep rolling in. haha: "cheap, easy, fail, mini tuning circa 2003, power, snake oil, spam, speed, sprint booster, stupid"

First question...yes, I have driven cars and motorcycles in various states of performance. I have worked in the past for JE Pistons and as Marketing Director for Nitrous Express and currently as the Feature Vehicle Specialist for the SEMA SHOW. Needless to say I have been around (I'm 42...eek).

There is no HP Gain...just accesses the the existing HP sooner...just changes the delivery curve.

If I understand the device and what you're claiming, then all it does is change the response time from accelerator to throttle body? If this is its design, then the same effect can be achieved with a good sense of electronics and relays.. which I'm sure is what you're paying for.
No idea if it is patented. Manipulates the electronics. Again, just changes the curve of the throttle input, so at quarter throttle, instead of being 15% open, it is 25% open (not exact numbers...just for discussion purposes). You are correct, it changes the response time. I am sure, provided you are a combination Edison and Macguyver you too could work this out...but I am not even gonna try that one.

I think I explained above, but to cover it I will use a motorcycle reference. Not sure if you will understand this reference but here it goes. Back in the day we used to change the carbs out on our motorcycles...think flat slide Mikunis. For drag racing we would install a 1/4 turn throttle. No HP change by using the 1/4 turn throttle, but the power would come on sooner as a result of using that. Same principle...top end is unchanged...hp is unchanged...power application is changed by opening the throttle body butterfly sooner. Simple concept via electronics manipulation.

You could probably ask them more technical questions, but you will also probably get more technical answers.

A fair response. I am usually over at NAM, mainly because I consider people over here a bit more "evolved" as to tuning their MINIs...which is not a place where I belong all the time.

I have to say that I expected this response based on the research I did on the product. I am a big fan of the Underdog...I just thought I would use my voice to give it a fair chance. If I ever become a spammer, it will be for my clothing line putting Rally out of business!

$300 bucks is ridiculous. It probably costs a few bucks to make.

I'd like to hear what Nitromini has to say about this thing, he has one. I've only driven one other Mini besides mine and it had a sprint booster. The throttle responce was incredible but the car also has intake,pully,coil and a few other things so I cant really say if it was the Sprint Booster.

Yup. I'm familiar. The first car I rebuilt was a 68 cougar. Carbed. The mini I have now is carbed.I know all about it. It's JUST like the analogy I used above. It's the technological equivalent of tightening up the throttle cable, or even using a shorter, tighter throttle cable.

Which is why I can't justify the $300. I'd much rather just mash the skinny pedal when I need it.

If it DOES reduce the endurance of the curve (Make the distance from full closed throttle to full open shorter) then what you gain is this feel of a "More Sensitive" throttle. But in all actuality, you are losing sensitivity. It means you have less control of that percentage between 1-5%. Instead this module makes you automatically jump to 5%.

To each his own. If you love it, then that's AWESOME. But for future reference, all of the above information in the first post would have saved at least HALF the comments in this thread.

I believe you hit it right on the head...It cheats the ECU a bit...lies if you will. I regards to the "being a nancy and pushing the pedal to the floor", I mentioned in my first post that I got hit in the rear on the freeway. I was actually the third car in that particular accident. I heard the Van and looked in my mirror and saw him slam into the civic behind me throwing the hippie into the air inside his car. At this point, I romped on the gas to get out of the way...nothing. Then the civic was pushed into my car. The Sprint Booster has taken away that lag which is my main reason for getting it...safety as I see it.

It is really easy to swap out...I would ask the guy if you could try it in yours. I have a pulley and exhaust.

I anticipated some reluctance, so I somewhat welcomed the dialog. I don't know about losing sensitivity for sure, but I was able to drive to work this morning and without jumping on it, felt completely like it wasn't there. I do however understand your point.

On a completely different note...damn I want a classic! Club member has one for sale but he wants $17k

He sold the car already. I actually called him to buy the Sprint Booster before he got rid of it but I was too late. I do want one, I believe it helps with the hesitation you get when taking off which you are correct about the safety factor.

I would be interested to see that info...find it if you can. It probably cost $5000 to make your MINI...what is it worth to you?
