has any tried a larger throttle body yet ive got a 02 cooper and wanting a bit more bottom end (acceleration) wondered if a larger throttle body would make a differance

Hi ,we do a 57mm TB for the Cooper. We havnt measured the performance increase but they do feel a little more lively. They are £239+vat on exchange.

Not much "bang for the buck" from a larger throttle body. They might improve throttle response but offer little power gain.

2-3 horse power for £290!.....

tbh any modding of the Cooper yields only small power increases 'per pound spent'. Cooper S is the one to go for if power/modding is your goal.

Horsepower is not always THE thing!
Because the larger TB I can use my max. torque and HP earlier!
I have the TB of M7 Tuning, they flat the ash too for more airflow.

Thinking of getting my throttle body machined??? Does it make the car feel faster lower down?

MiniG · Feb 4th, 2007, 06:21 AM

I haven't had a look into the stock TB yet, is it a two stage type or a single valve? Also, what are the aftermarket offerings? There used to be a mod for the 1st gen water cooled VWs that was called a "Big Bore throttle body and it made the car much more responsive but virtualy undriveable!
It was like an on/off switch.
Swapping to a larger two stage TB felt better and did allow more airflow in at a time.
Is there also room for improvement in the intake manifold? Port and polish type work?

It's nice to start getting back int this stuff!

got my throttle body today i know it wont increase bhp but will ad throttle response so thatll do for me when i get a re-map that should help more to thinking of gettin blue finns will be lot easyer to install for me been in the middle of nowhere

Does the larger throttle body make much differnence on the Cooper S, is there much involved in the fitting of it??? I assume might make it a little deeper on acceleration too, with potential for a few more pops from the exhaust.

On the cooper you are better off sensibly modifying the existing throttle body which will provide as large a power increase for less than a third of price! Quite a lot can be done to these including machining the screw heads, polishing and edging the butterflies
