Cant you just wear thicker shoes to have the same effect?

Driving in flip flops is always exciting!!!

If you move the seat a notch further forward and more upright it feels faster also.

Ive had a sprint booster for about 2 weeks now, this is on a 53 plate cooper.

MY verdict? Well its the most noticable 'boost' todate (8.5/10), with alta panel filter coming second (7.5/10), and worst value bluefin (5.5/10), although happy with all 3 purchases.

The sprint booster, well my first thoughts it was almost like having another first gear in second

Very responsive, but easy to get used to its sometimes savage response. Makes higher gears if the revs are 3500+ nice and torquey with plenty of instant reaction. 5th gear has nice pull at 70+. One thing the booster appears to do apart from making things a bit more responsive, it makes the distance you have to press to get open throttle a lot less, not sure if thats a good thing, almost a cheat to make the car feel to have faster accelleration, when it doesnt.

I would recommend to anyone, but at your own risk, its a fiarly new thing on the market so its not tried and tested, is that a fiar evaluation, or would you consider it completely safe on the car?!

Finally got around to fitting this to my R56MCS tonight.

Bad news, as it doesn't work with the stop / start 08 model year cars it seems. It fails to start and puts up the engine check light symbol.

Take it off and after 3 starts the CEL is gone. Does this need clearing properly ( in the ECU memory ) ?

Back it goes

would yours be suitable for a Cooper D. I might buy it off you.

How does the Sprint Booster effect low speed manoeuvres like parking (both forward & reverse) etc?

Just asking as someone above ^^ states that the response is "...sometimes savage..."

Supplier checked with Sprint Booster head office and it seems i have a faulty unit. They are going to supply a replacement

All i'm interested in is 'gaining' the throttle response of sport mode ( r56 ) while retaining the non sport steering feel / response.

I'll let you know once i fit the replacement

Hi AberdeenAI, you have quoted me, so ill try me best and answer...

It seems to make the pedel very light and quite sharp in its response, but strait away it wasnt too much to get used too, and now having it for over 2 weeks i definately dont want to go back, and have no issues at all with slow speed manovering or control, it dont appear to afffect reverse (noticable anyway) at all, only forward.

hope this helps a bit..

Checked with Sprint Booster Head office and apparently i have to leave the car for 30mins before fitting this unit.

Anybody else had to do this on fitting to a R56

[Japper]

Well, it worked

It is sooooo nice to have a proper throttle response again.

Not too edgy and not hard at all to manuever at low speeds. Infact there is still just that little bit of play, more so than the OEM Sport button mode, but then after that........wayayyy

Sport mode isn't much more sensitive, so still driveable but oh so much sharper.

All in all, a great buy and 2 mins to remove and put in the next car ( all bmw's ) or sell on.......bonus later

OK ,another positive report ! -so far only R53 and R56 cooper s its not quite the same as wearing bigger boots is it ?
So far all the reports from customers have been positive ,none returned,no faults,-japper is the only one I have heard of with a problem and none from any we have sent out .
They have been fitted on both remapped and stock ecus and both cases with positive results.
I have no idea why the ONE /COOPER owners are slow to take up the boosters?

Because if we had more disposable income, we might all be driving the Cooper S?

I like the sound of it, but I'll be getting an ECU Remap done as a priority over the Sprint Booster Throttle Remap. The budget doesn't stretch to having both done in the near future.

All the best,
Andrew.
