Tuning a modern forced induction, direct injected gasoline platform is one of the best bangs for the buck out there. It's not uncommon for 3.5 ecoboosts to see close to an extra 100 wheel horsepower and torque from tuning alone. Tuning with ethanol mixes is even more impressive. Do you realize there are F-150's with the 3.5 EcoBoost that are stock from the air filter to the exhaust tips simply running a ECM/TCM reflash that can crack off 3.xx seconds 0-60MPH and run the 1/4 mile in the 11's? That's a sub-$1,000 investment to shave two or more seconds off 0-60 and 1/4 mile times. To shave off another second you are looking at upgraded turbos and fueling. You are into it for thousands of more dollars chasing that next second reduction.
Maybe that works for an occasional 1/4 mile race. But that’s about it. Power = fuel + air. More fuel and air creates more heat to get rid of. Short term no problem, but do that reapeatedly or constant, trouble comes quickly. Heat soak, timing retard etc… then the car gets slower and slower…
Gears in the rear end is another factor too. There are some tuned Expy’s around that are still slower than my SPP factory setup.
Ethanol, yes… I’ve been told that… problem is we don’t have that option. Our gas is blended between 5 to 10% ethanol at the pump, but there is no E85 to be found. I can’t try that even if I wanted to.
What I can confirm is the 24 3.5L HO works incredible even on regular gas. Same as a 25 2.3L. Very happy with both of them.
I am about sea level height. It shouldn’t matter with forced induction, but I think it does, since the air is also not that brutal hot at the coast.
My GT500 has a built engine and does more like double the power than stock and does this consistent all day long. It’s only tuned for 90 octane pump gas. Again…. 91 is the highest gas we get here.
Must be nice having the option for 93 octane gas and E85.
