For local track days at PIR and such, my buddy enjoys his 435HP Coyote in his F100 but when he was doing the Optima series, it just didn't cut it. He's looking to add a supercharger to get him in the 650 range.
It all comes down to how you use it but an additional $1,000 for the additional 160 horsepower and many, many smiles seems reasonable
