Simple question, tricky answer.
Going throttlebodies on the yb ( turbo) and was wondering about which size to go for, jenvey has some from 40mm and up. This isnt a big bhp monster alltough final enginespec are to be desided.

 

Why when a standard TB is good for around 600bhp ?

Throttleresponse! It wont be 600hp either, probably in the region 500-550

 

No one? Does anyone know the approx throttle dimensions of a mountune inlet then?

 

would have thought 40-42mm would be enough.... 45mm might be excessive below 600BHP
