we are not talking about the E charger.
the E charger is a legitimate product and it acturally makes 1 psi of boost.
these 30,40,50,60,70,80,90$ pos are just boat blowers that where made to vent the gas from the engine compartment before ignition.
It does not create any preasure and maybe it might flow 350CFM if the out let side is at atmospheric preasure but if you wanted to make BOOOSt... its impossable.
I got one of these on by boat and it vents the exhaust gases quite nicely. Also i see a 40HP boost when i turn it on :biggrin:
Echarger on the other hand is a serious fan... and would displace enough air and generate enough ACTURAL GAUGE preasure to register 1 psi which would off set engine vaccum during WOT.
its still pretty expensive toy tho.
+ for echarger but negative x 10^inifity for the boat blowers.
happy motoring.
