VP Race Fuel. 14% HP Gain? VP claims a 14% HP increase using their "Street Blaze" 100 octane fuel.

Does this hold water with you? I think that is a bold statement. So if your running boost,and your running VP and you add meth injection what kind of power increase should you see from just plain old 91 pump gas? With my setup currently and adding the claimed 14% I'll add 126hp

Also highly oxygenated fuels (VP import for example) make more power, just have to throw more in to do so. But putting that in a stock car would get you nothing most likely. Of course you can add more timing/boost or whatever but then its really not the fuel thats making more power, it just allows you to make more power

But highly oxygenated fuel will make more power, just wont pass a fuel check. Trending Topics

5psi? Maybe from 91 to 100 (9 full point difference in octane, on a 346 motor you can add about 1psi for every 2 points I think is the rule of thumb)
Even on KP's off days, he'd still know more than me, though.

So their 14% claim of power increase from 91-100 could be valid if somehow a car could adjust itself for increased octane like RW99 said. Just putting it into a non detonating car without changing anything will see a few % power increase from being oxygenated (maybe) but thats it.
