I used to have the Nova BF21 limited 3 port back in the day and put it in truggy and it was fine. I wasn’t racing yet and had just begun to hit a smaller track but cleared all the jumps and moved truggy around no problem.
I share that bc the Mantra is better and has More power plus truggys now are better then 9 yrs ago so just sharing why I think you’ll be fine; you might lack a little in truggy on a bigger track (keyword is might). I would say go with a 7mm Venturi or larger
if you want. Might lose a little on fuel mileage (I’m running 6mm in buggy) and good pipe combo.
I would say to try 41001, 41005, or 41031 for header. Pipe I would say probably 2096, 9853 or maybe 9886. 9901 or 2135 are good but I think would lack for that engine in truggy.

When I put the 41001 header on with 2135 pipe it had too much torque for me in buggy.
The 9853 pipe is a better low/mid pipe so I would say the 41001/9853 combo would be a good place to start for truggy.

Hope this helps a little, good luck with testing.
