oettingerA4 4 Posted May 6, 2019 Report Share Posted May 6, 2019 Quick question, what would happen if I closed the flap or left it fully opened. As going the turbo route, would it really make a difference opened or closed? Sorry must be a stupid question, but need to ask🤠Link to post Share on other sites
RBPE 198 Posted May 7, 2019 Report Share Posted May 7, 2019 Without the ecu mod/box they'll be stuck in one position anyway dep on what ecu you're using, so make sure oem ecu mods for it or if going aftermarket, that those ecu's can control it.  Is it a 2 port design, not barrell like the 24v, so one port will speed gas up giving better low flow rate but ultimately becoming a bottle-neck creating turbulence, heating the air up more and losing you power as the air flow increases and the dual ports will lose you this low gas speed in exchange for top end flow and opposites of above. If control is like the 24v's then it'd prob be stuck in power position/dual ports open in default if no ecu control. Link to post Share on other sites
