We can always turn a simple question into a long debateYep. Granted, 48/50mm may be rather OTT on a stock motor, but for someone like myself with bigger plans, it’ll be ok in the meanwhile.
If it had 500bhp stock, then having it that oversized would make it undriveable. The tiniest amount of throttle pedal would give you 100hp!
With a stock 150/200hp setup though, it’ll probably just feel really torquey.
The MK4 Golf R32 is an example I often use. It’s electronic throttle, obviously, but not mapped 1:1
At the start of the pedal travel, 10% pedal actually equals about 30% power, to make them feel really snappy and torquey.
Trouble is, the last 30% of pedal feels totally dead, as it only makes a tiny difference to blade angle.
It makes people with R32 golfs think they’re really quick, when actually the throttle is being artificially stamped on for them.
Also, what an awesome forum this is, that a quick question about a versus b throttle bodies has turned into an interesting and engaging discussion about throttle body tech!
I would!I’d like to end up with a solution I could put together as a complete ‘ITB Conversion’ for the UK/EU market, complete with a base map. I suspect those who aren’t so confident would appreciate such a thing.

Same I think. I really don't know what route to go down with my engine. So many options!I would!
Yep, just like that!Ah, so those Golfs have a permanent version of the sport mode in the E46 M3 then? Or like those Sprintbooster things you can get?
No, they are fixed. It's just a hole with a butterfly in it.Do throttle bodies have interchangeable choke tubes like the carbs do? If so the quoted bore size is less important apart from going too small.
Poor butterfly.No, they are fixed. It's just a hole with a butterfly in it.
