I have a 2004 Mustang GT 5speed

93 Oct Bama race tune
I like to race my race about onece a week at the track and I have always just used octane boosters(VP 8 number booster). I found a pump near me that sells much higher octain like around 100-120oct. Could I run this gas? Are there dangers To it? And would this really be any better then the VP booster? I have used the booster for over a year it's not magic but it give a little boost if consistently used at each fill up.

Technically you should find out what the block is rated at, piston rating, manifold rating all that good stuff because you can blow the motor, hypothetically speaking if it's from a gas station you should be fine, I've found more octane equals better mpg but I know the number my block can take so I've never gone above that
Nothing you have done has changed the compression ratio of the engine. Using a higher octane is just fooling yourself and wasting money. Octane rating has zero relationship to the power the fuel contains, just how well it resists detonation when compressed.
The reason that you may need to use higher octane is if you have increased the compression ratio, or are using forced induction (turbo / supercharger). These are common ways to actually get more power from an engine, hence it's done to "race" cars. This actually increases the pressure in the engine, and if that causes detonation, the engine will be quickly damaged.
But NONE of your mods have changed the engine internals (or produced much extra power). So you get no benefit from higher octane fuel.
Nothing you've added requires race fuel. High octane fuel doesn't provide more power. You haven't increased compression. You haven't modified the engine to run 8,000 RPM. There's no reason to use a higher octane than pump premium.
It really won't help. Even with these bolt ons your engine is basically stock and pump gas is all it needs.
- Which car would win in a race? 2005 ford five hundred vs 2011 volkswagen jetta sel ford: CURB WEIGHT 3664 lbs v6 TORQUE 207 ft-lbs. @ 4500 rpm HORSEPOWER 203 hp @ 5750 rpm ENGINE SIZE 3.0 L vw: curb weight 3,082 v6 i think torque 177 lb.-ft. @ 4,250RPM horsepower 170hp @ 5,700RPM engin size 2.5 L
- Which one of these cars will win in a drag race? 2015 dodge challenger hellcat, 2015 ford mustang gt350, or 2015 z06 corvette? Also, which of these three do you prefer driving?
- Entire car loses power when we floor the gas. Gauges reset until we let off gas. (still drives) 02 ford mustang. The car loses power to everything. (Except what's needed for the vehichle to stay running.) Can still drive it. What are possible problems? (AC does not affect anything )
- Must I put premium gas in my 1965 Ford F100 390 V8 or can i put regular gas? I was told that it needs premium gas and premium gas only. But the guy who I bought the truck from said it was a myth and it takes regular gas. What gas does my Ford F100 390 v8 engine take?!
