Some of the higher reving off roads like an xZ-b os or a werks b5 must be able to keep up for half the price. Thoughts
There are so many factors in this
For instance the guys winning the GT races here locally are running the 4 port BTT in both variations BTTA and BTTS. Since we are setting up tracks that are tight with a straight around 200' the RPM doesn't gain you much.
The flip side of that is say GLARC. That straight goes on for days at a time giving RPM the upper hand there. For GLARC I'd lean towards the 9 port Flash Rally but its not a cheap motor. Other choices would be in the range of the Top motors or the 7 port Kappo Rally.
As far as a cheaper alternative goes we often lean towards the Basic Sport motors like the N21-5t or the N21-R7. Both motors are very solid and have proven themselves to be contenders. These motors are very well rounded so this is often where I point guys who are looking to save $$$ but still have good quality.
My favorite part of GT is engine is double edged. You can go with an Off-Road setup on a small track and dominate due to massive bottom end. You can go to long track and listen to the 46.8k RPM of a Flash and bring home a win with RPM. They both don't have an advantage until track length takes effect.
At 3500 grams it is a very flat field as far as motor goes. You can get RPM crazy or you can get Torque crazy. You can also find a mid range and be well rounded. That's my favorite part; if it weighs 3500 grams I don't care what you have in it lets race
Here are the motors I talked about above
