All 3 are great motors. More ports will give you more top end.. So for the long straight the RB S9 with it's 7 port will give you the highest top end. The Plus 4 and P5 are similar on paper. The plus 4 is more popular since it's a new design and the P5 has been revised and updated through the years.

For power the FMS

From th motors listed it's a toss up between the 21-4 and P5XLT. I like both.

im running a p5xlt and i also picked up a +4-c ....the p5 is a monster bottom to top ....the +4-c i havent run ...but the concensus seems to be that not
near as much top as the p5 but great bottom and smooth ...cant say about th rb i have never run one ...depends on the tracks you run mostly ...i got the p5 for the all out tracks and the +4-c for the medium to smaller tracks .....either brand they are surely very good quality and if taken care of .....should give lots of longevity call me crazy but if grp was still making motors i would be running them ....

edit ..i just saw the 180ft straight ..get the p5xlt

well the p5 takes an 086 pipe set which is about $50, not bad.

I have no idea bout the 2045 I've never ran one, but the header i think would give you more bottom which you don't need on the p5 or 21-4.

It's up to you bud.

Dynamite 086 pipe is awesome on Nova 5 ports.
I've never ran the RB S9, but I don't like the fact that it has a 13mm crank and standard plugs. I like turbo plugs.
