400whp 5.0 coyote
 

What’s up guys as I am new to the forum! I bought a 2014 f150 with the 5L coyote and was wondering if 400whp or close to it was achievable reliably on 93 without any type of forced induction. I know a good exhaust, cold air, gt ported intake, throttle body and custom tuning will up the HP and torque a good amount but will it be in the 400 wheel hp range? Preferably a little more.

If you assume the typical drive train takes 10-20% of transmitted power, to get 400 rwhp, you will need about 480 fwhp. The 2018 Coyote engine puts out about that (460 hp), with new heads, intake, and a slight increase in displacement.

But one has to be impressed with the Coyote engine development team, who manage to get another 20 or so HP out of the same basic engine every couple years above the previous version, which they always state was maxed out.
