5 ports overall will def be faster than the 3 port in all areas. It will have more bottom and top end. Great to run at tracks who don't abide by roar rules, but if you get ur ass handed to you by a 3 port then yeah...just goes to show its all skill.
With that being said the ORION CRF is the fastest you can get right now. It's inexpensive, reliable, and godly fast. Buy one...buy one today!
