So running a JP3 on an Evo3 Picco on an old, heavy Jammin' X1cr buggy on a short/med. sized track getting 9+mins is bad?
I ran the same car on the same track (same day) with a Nova Plus21-5k and Nova 9886 and the GRP 2053 pipes...got the same mileage with it...the Picco/Jp3 was right on top of it.
Now I KNOW the GRP's and new Nova's will/can do better...but also on much lighter chassis configurations (the Losi 1.0 and 2.0 are over 10oz. lighter than my car).
As far as temp goes, I don't know...I've only run it on the Picco, but she holds a rock steady 225 without issue.
