PRO-720 dyno walkthrough: 720 hp, $28k, no asterisks
Three pulls. Same fuel. Same room temperature. Here's what the PRO-720 actually does on the rollers.
We rolled the PRO-720 onto our Mustang AWD dyno on a quiet Friday afternoon and put it through the same protocol we use on every customer build. No timing tricks, no hero pulls, no asterisks - just three back-to-back runs on 91 octane and then three more on E85.
On 91, the engine landed at 712 hp / 668 lb-ft at the crank, peaking at 6,400 rpm with a usable torque plateau from 3,200 onward. On E85, the curve filled out and we saw 738 hp / 691 lb-ft, well within the documented envelope. Most importantly, every pull was repeatable to within 1.2%.
The takeaway: this engine is exactly what the spec sheet promises. No detuning to make the launch numbers pretty, no spike-and-fade. If you're shopping forced-induction V8s in this range, ask for a dyno chart of three consecutive pulls. We did - and we'll publish it for every engine we ship.
