It was designed to be blocked off (by the resonator box). Being as the wheel arch vents are for the 1.2t intercooler, theres obviously a flow of air through the area of the pipe end. Therefore, there may be a flow of air through the intake, out through the unblanked pipe end, instead of into the engine IMO blank it (I have)
I would also blank it. My old car I removed the resonator (in hindsight using a hacksaw to get it out of the tight bay wasn't the best idea as when I went to replace the forge intake pipe I had nothing to go back in :lol it was simply replaced with a replacement tube as it was directly part of the air filter housing.
Did you notice any difference to the drive with there being less going on singlespeed?
with the design on my old car there was a very, very noticeable increase in torque but obviously the design was different as I highlighted above
A touch more induction noise, but not as much as removing the airbox bung (now refitted). Noticable performance difference - none. It may make a difference on a dyno, but in real life, theres nothing in it. This morning, the postie delivered some Samco hoses, with the resonator delete option, so no blank required tomorrow.
sweet. look forward to your thoughts. Silicon pipes can make such a difference. and obviously are bound to last much longer than rubber hoses that will eventually let down a reliable engine.
