New to the forum, if you're willing to give it I'm in need of some info about the Lenco transmissions, first and foremost the pressure when using air shift. Does it have to be exactly 150 psi and 250 psi respective to the version of the transmission? I'm looking at putting a six speed unit behind a 532 cubic inch, fuel injected big block Chevy with twin 76mm turbos, hoping to put out 2,600 horsepower at most, however as it'd be mainly a street driven car it wouldn't be on the full power tune all the time. I'm looking at either the Lenco or a 4l80e, my biggest concerning factor aside from cost was footprint given this would be in a makeshift transaxle setup and so it being overly long would adversely affect the footprint of this project. I don't want to do CO2 because of it being a street driven car and potentially being left stranded in whatever gear I'm in once the bottle exhausts itself, I'm going to do an onboard air system with either an ARB air compressor or, depending on shift pressures, a modified York 210 air compressor mounted to a single phase DC motor. Thanks in advance for any and all help.
