[QUOTE="tt335ci03cobra, post: 16265942, member: 68944"] 700-715whp. 12psi in a modern 7500rpm coyote 5.2 with 9.5/1 and very capable heads is going to make more than 474hp. I’m guessing about 485hp na at a minimum. 12/14.7= .816, then add 1 to account for the na engine. 850hp/1.816=473.6hp. If we use 485*1.816, we get 880hp. Take away 110hp to run the blower and we have 770hp. I assume it will eat up about the same torque to turn 7500rpm as the 10a gt auto does. That would be about 40tq to represent about 57hp. 770hp-57= 713whp. I’m assuming net hp with alternator and water pump etc from the get go. The average 03 cobra’s made 360-370whp. They spanned 350-387whp from what I recall. I think we’ll see 675-725whp for gt500’s with outliers, and 700-715 most of the time. (Quick afternote: Let’s also point out the 5.2 voodoo with less flowing heads makes 526hp. Let’s say the gt500 heads helped it make 1.5% more peak hp but less torque midrange (ie why they weren’t used) with 12/1 cr. That would mean 534hp. Take off 3% cr 12/1 to 11/1, 3.5% 11/1-10/1, and lastly 2% 10/1-9.5/1= and we get 491hp... 12/1 vs 9.5/1 compression accounted for, and heads assumed to only be worth a whopping 8hp on a gt350 5.2) 491*1.816=891hp. Take even 110hp to drive the blower and you still get 781hp. [/QUOTE]
