I have a 6.5 in my Lazer and a 7.5 in my 22-4 - different motors. From what I have read, the 22-4 is better suited to a 5.5T.
The 22-4 is 200g heavier than the Lazer. That is almost like carrying around another battery. I figured I can turn down a 5.5, but I can't turn up a 7.5. I am actually running the 7.5 on a 21 tooth pinion - I don't recall the gear ratio but this is higher than TLR advise in the manual. I also turned the boost right up on ESC for the 7.5 and still I could not clear the triple. It felt very underpowered. It was also running hotter than I'd like with the boost up. With the Lazer, a quick flip of the power gets me from one corner to the next very quickly, you can see the car accelerate and it feels great to drive.
I guess this is my preferred driving style - more aggressive with lots of power. This is why I prefer the higher C batteries. It is not so much the continuous discharge rating I look for, but more the high burst C rating as that is how most of us drive on the track. I actually have a 25C battery and it feels like driving a dead horse around the track.
I think putting a 5.5 HPI in the Losi will change this. Those motors are known for being quite quick too.
