newest numbers for 5.0 coyote 405rwhp/375rwtq

[Lifter583]

Two observations:

1. Although quite impressive, stock it dyno's @395rwhp, so if this is true then 405 aint much of a jump. Inside Line Dyno-Tests the 2011 Ford Mustang GT 5.0 not sure if they tested it in 4th or 5th for that run or how much it matters.

2. Ive been reading a lot on the stock rwhp on the GT500's and seen much of this:

"I have an 07 GT500 bought in Jan 07. Stock with exception of Borla Ex. system. Ran it on DynoJet here at the college nearby and showed 512 at the crank and 437 rwhp. I live in the AZ. desert ran in cool month of March elevation about 500 feet. Only had about 2k miles on the car when I ran it. ,,"

Of course, you can up boost HP more easily than NA, but this new 5.0 engine sounds like quite a runner...almost revolutionary.

I found an 08 GT500 with 558 miles on it...added a $1200 Brenspeed stage 2 performance package and now running 550 rwhp...approx 645 crank...it is so far above a stock 500...I certainly advise all 500 owners to do this and have fun vaporizing the new 5.0s...

I've seen quite a few numbers in the 370rwhp range stock I've been quite curious about this because a salesman at Ford told me that FoMoCo sent a representative down to train them (just a week ago) and the representative told them Ford did in fact under rate the horsepower for insurance reasons.. and said it really has 442hp.

So yeah, I'm not sure about the horsepower.
