What do you think would be a solid set up for a serpent s411 i don't race or anything just want the car to be crazy fast and be able to tune the ESC any ideas

Just strap on a couple of these...
Model Rocket Engines | E Model Rocket Engines Certified Model Rocket Engines | Model Rockets | Hobby Rockets | Flight Supplies | Estes Rockets ...and you'll have all the speed you could ask for

In truth though, if you just want speed, go for a 5.5t or 6.5t motor with at least a 120a speed controller like the Hobbywing v3.1 120a ESC or the Hobbywing XR10 Pro 160a
