cheers guys, im on an external turbosmart wastegate with 14.5psi setup in there at the moment but quite fancied the ability to run lower than that for wet weather and the mrs,
now need to get one, what do people use or recommend? i have looked at the turbosmart stuff liked the e-boost 2 with gear dependant boost but when ive looked at it its on switches not by rpm and speed which i think is abit pants
There is no generic answer as every setup is different. Trying to achieve 28psi with a 7psi spring is pushing extremes, but it may be possible.
And certainly the E-Boost 2 is a fantastic boost controller. If any can do it properly, it will.
But no, you cannot run lower than w/g spring, unless you use a controller that operated off CO2 or compressed air which could blow the w/g open. Not exactly practical for a road car.
E-Boost 2 does claim boost per gear....Ive yet to figure out how as it has no way of knowing what gear you are in. They also didnt reply when I queried them. Closest I could see is some sort of time delay boost increase.
If your ecu can control boost, any decent ecu will be able to do boost per gear or speed or other setups.
