Q-trim vs. P-trim

[YellaGN]

Anyone have a detailed explanation of why the Q-trim is better than the p-trim? Did a search.....and only found "makes more power", but no information on how, how much power, or spool differences.

Where did you read it is better? I have never ran the Q wheel but by design and size you can pack more air between the blades which should = less backpressure and more through-put. This should also make it a little harder to spool unless you are flowing the air into it to get it moving. The P wheel is the opposite and will not flow as much on the exhaust but WILL spool quicker. I think the P is great for street and track where the Q may not do as well on red-light snaps. One of these days I may try the Q to see first hand but most people like the P better on the street. Make the decision on the use and not the hype.
