i have seen the same loss results on the dyno everytime we have run these. There is no 30-50 HP loss but there is a 7-10 HP loss everytime. A carb is not designed to have air entering from straight above and it really does disturb the air flow characteristic of the carb. if you want to see a serious loss in HP put one of these on a Q-Jet. I have seen almost 20 HP loss on 450-475HP motors with a filtered top and Q-Jet. these are definately a waste of money, and i am not ashamed to say that K&N got me on this one as well.
