for what it's worth, i have one of the mdc BB 60 trims. i opted to test it for jon, knowing very well that it might not last. that was and is a chance i'm willing to take.
for the time that i was running it (i took the car apart a year and half ago), when you pressed the gas pedal, i swear, all hell broke loose. it was ridiculously fun!
it had a smooth, ridiculously fast powerband right up past 6.5k rpm. stomp the pedal, and you're literally gone. i was running 15psi through it, and i was having an absolute blast.
i'm hoping that it'll keep together, as it was a potent little guy. it spooled faster than my stock turbo, if you can believe that. man, i miss boost.
