Performance Build in process

[Cody Dawson]

Side note: if they only made 500 hp on the flywheel then That’s much more manageable

thanks for following along, I’m not aware of the Raptor R engine build but as far as getting 500whp from the 6.2 just on the motor would require the custom cam and 12.1+ compression ratio. Along with many other variables. It wouldn’t be realistic for street use.

Ah, thank you. I did see your next post about 500 at the flywheel being more easily obtainable. Drivetrain losses huge on the Gen 1 Raptor, from crank # to the wheel dyno #?

just in RWD with a big tire it’s losing around 25%

Sounds about right on the drivetrain loss on these trucks. Mine is right at 25% loss based on where I believe the truck is at flywheel horsepower. (630-640).

Killer engine build Cody!

Edit-I must have had an old tab open and didn’t see other posts....


So is that assuming 15% driveline loss? Basically 625 at the crank naturally aspirated? What is a realistic street use horsepower number out of a naturally aspirated 6.2?

I haven’t seen enough data to accurately guess that number. 625 at the crank would be tough to achieve on 93 octane. E85 is becoming a more available street fuel and allows you into the 14:1 CR area. These engines are heavy, I don’t know the RPM limits of the stock crank but to make big NA horsepower you need the RPM.

Looking good Cody - can't wait to see what she puts down!
