Hello, just out of curiosity, is anyone running a 50mm throttle body? When is it a good time to upgrade to a 50? Any gain/loss?
Porting is never necessary, but your wasting your money adding performance parts that won't reach their full potential. You'll find few people running a 50mm because it is easily outgrown. A 47mm and 54mm overlap the powerbands making the 50mm almost a waste of money.Does the head need to be ported to run the 50mm throttle body like the 54mm?
What are your modifications?I asked Cuervo Racing for a map and they offered me the 47mm.
In fact, it is a lot more expensive than here in France.
This company looks super professional.
They sent me a free map.
As a thank you I take the Mod 47mm.
You think I should take bigger?
I would say you're in the -60HP range, so go with the 47mm throttle body. That is a factory throttle body machined 3mm bigger and a new throttle plate to match. You'll need a map adjustment to match.Hotcams 3
