Increases BHP
Increases torque and acceleration
Improves throttle response
Removes hesitation and flat spots

Worth it? they are £120,going to be fitting my inlet in the next week so might chuck one of these on while im amoungst it...

Just clean your own throttle body when you fit the inlet.

Just give yours a good clean with some carb cleaner as it will be filthy.

I woulnt spend £120 on somthing that will give you about 1 bhp if anything at all of in a increase.

When powerbox's are almost the same price and give a proven increase, The ones im going to be selling at the end of the month recently got 17bhp up on standard, with the only mod being my powerbox. Also have the rolling road graph if you want to see it?

What does gas flowed even mean. It's another one of these non-terms you see all the time.

You've never heard of gas flowing

Its a very common term, eg a gas flowed head. Don't see how a gas flowed TB would make any difference at all, because its that short and not restrictive, I would only buy one if the bore was increased.

But in what sense. I think I'd trust the engineers who designed the induction system to produce a decent throttle body for the engine, not some bloke in a shed with a dremel and a Wikipedia degree in engine design.

oh right. so removing lumps of metal out of a throttle body isnt going to help it at all is it not?

yes in gas flowing TBs is pointless, but gas flowing cylinder heads is very much not pointless, as you can make decents gains from this.

Maybe, but maybe not. You've got to have a TB that matches the fannymold design along with a suitable plenum.

half the time the throttle body and manifold arent matched anyway. thats not how they will have been designed.

In what sense are you using the word matched? The throttle will have been designed to work with the manifold. It would be slightly embarrassing if the engine ended up running rich on 2 and 3 but lean on 1 and 4.

have you ever checked that the tb lines up (hole in it i mean) with the manifold? casting irregularities occur frequently on mass produced stuff. thats not how it was designed is what i mean. so yes, taking a bit out will help it.
