Good job inline - carnage means you've been having fun. The traxxas ESCs have a rev limit and struggle with 4-pole motors since they are effectively twice the KV to the speed controller. It was a great ESC a few years ago but its falling behind the newer stuff thats out there in my opinion.
I recommend the mamba max pro, its a sweet ESC. I've had a few for a couple years now and they've been perfect. The fan barely needs to go on under the hottest conditions. Analternative would be the SV2/SCT setup and get the 3800 kv motor (look up a few posts). The price is just over 100 and the setup is for heavier short course trucks so it won't work very hard at all with the firestorm.
