[QUOTE="VNMOUS1, post: 15048053, member: 36794"] Pretty close Trap says it's a mid-11 car all day long. 116 ties the trap speed of Brad Gussler's dedicated SCT/Watson Racing Eco which weighs a bunch less. This one is full weight, seats, head to toe exhaust, an overnight bag in the trunk and a full tank of gas. And my big butt in the seat at 2 bills. Traction is not an issue. Getting on the turbo is the issue. The factory converter is good to about 2500. 2500 is around 10psi...or about half of where it needs to be to launch hard. It's the mid-size EFR offering. The smaller one will spool more quickly but won't support this kind of power. A 4000 stall will get us where we need to be. The thing is a *&^%$ rocket once it's on the boil, picking up 23-24mph on the big end. You can be running 20 mph down the street, mat it, and it'll absolutely paste you to the seat. There isn't a stock nor tune-only Coyote that will touch it. It makes as much power as a tuned Coyote and weighs nearly 300 pounds less. e85 isn't an option. As it is, we drain the rails at the hit and supplement it with 100% M-1 to keep the rails happy. Remember, this is a direct injected car. There is an aux rail that you can use for a second set of injectors, but you can't do e85 and supply the volume necessary on a stock system. bj [/QUOTE]
