Well, if you are limited to 6 cylinders, yes.
If you can run a larger engine, that's always going to make more power for less money.
Ford went from 450HP/510TQ on the TT 3.5L V6 to 720HP/640TQ on the S/C 5.2L V8. Using a less efficient power adder as well. The blower is consuming approx 75 HP and the V8 does not have DI either.
Run twin turbos on the 7.3L V8 and Ford could get over 1000 HP on pump gas while meeting emissions and providing a warranty.
GM just did the 1000+ HP TT V8 thing with the ZR1 with only 5.5L.
2025 ZR1 puts out 1064HP/828TQ.
