dont know much about them, and i was about to post how i was impressed by the change in performance on the dyno til i compared it to the charger.
here is the 300c:
i was going to comment on the HP gain, how they eliminated that BIG step in horsepower and smoothed it out.
but that was never present in the charger:
so maybe they just had an issue when they first tested the 300, i dunno, but it doesnt seem all that much better than a regular warm air/short ram intake.
my recommendation for short ram...air hammer all the way!
