I've had this truck for quite awhile, the engine even longer. This engine (3.3 Traxxas) has 8 gallons on it, all bone stock except for a new set of bearings about a gallon ago. Took the CVEC soft and put this airplane tuned pipe on it and ran it. The old needle settings were too rich on the bottom and too lean on top. I leaned the low and fattened the high and took to the street. The truck is definitely faster, albeit a little slower to spool up. It's very torquey, and the torque comes on a little later and way smoother. You can get into the throttle a bit off the line and the front end stays down. It wants to do rolling wheelies far more and easier. Did I mention it's damn loud? Yeah, watch the video and towards the end you'll heat the sound get all wonky when I rev the engine. My ears are still ringing and I only ran two tanks through it.
Jato suspension, Macs Products .21-.32 airplane tuned pipe, Traxxas N.Rusty header, Picco P6S glow plug, 20/11 custom fuel, stock 20/70 clutch/spur. The Jato suspension makes this truck WAY more controllable at speed. She's actually pretty nimble and fast for being what it is. The engine just won't die.
