If im building a car that will see the track a lot and I mean a lot, I would throw a TH400 in the car without thinking twice. But for someone like me, a car that see's more street use than track and not abusing the crap out of it, the 4r would be my choice. aj's car with the 4r is nasty. He still wants me to go for a ride in it but I refuse to go inside. On 12-14lbs that car is scary. Maybe next time I see him at mustang magic ill go for a ride, but I will tell him to put it on very low boost just to feel.
I have been in joeys mustang. mustang magics tuner. He has a twin turbo setup in his mustang 4v swap with a 4r. He rolls around on 10-12lbs on the street and says he barely uses the high boost button lol. lays waste with 10lbs
I'd love to take rides in these cars! I'm right near mustang magic too lol. Never have seen any of them around.
