64mm Throttle Body

Hi, best place to buy a 64mm Throttle Body that I can fit directly to my car without faffing? I've done some research and hear that it increases low down torque massively.
 
I wouldn't expect much of a gain without a map. You'll need the air/fuel set up if your pulling more air into the engine.
 
RS Tuning put up a dyno graph of a before and after a 64mm throttle body was fitted. The 64mm TB actually lost performance.

The graph is on their Facebook page iirc.

Oh wow! I'll see if I can find and post the results up here. If people search for it in the future, they can see then.

Concluded.
 
That's the one!

I ran a 64mm TB for around a year in my car, took it out last week and felt no difference driving at all.
 
You'll need a map. You can buy the complete package

belts, cams and map. Complete guess, but I'm sure it's around £1,300 all fitted and mapped.
 
Is this a good supporting mod for multiple upgrades? I.e. Cams, exhaust, filter bits, map etc
 
Anybody know the part nunmber of the standard throttle body (and inlet manifold)?

All versions of RenaultSports offerings use: 77 11 160 249. That doesn't suggets to me that even at 250bhp trim it is needed.

Upper inlets on all R3's is different however, so potentially some modding might be needed to that part (i.e Sussex Performance Inlet's)...

Performance isn't just gained by enlarging the inlets and exhaust, you want the smallest throttle body, inlet manifold and exhaust system that is big enough. You want as much air in and out as possible but you also want the air to flow as fast as possible. And a certain amount of air flowing through as 60 mm hole will be travelling faster than it would through a 64 mm hole.
