Dude, there are TONS of reasons to run a N/A car on high octane unleaded. Not just boosted cars benifit from it. Now you have to have the engine setup to take advantage from it and if you do so you will see a LOT more than 10rwhp. Higher octane fuel also helps runs the engine cooler.

One of my bosses has a Corvette with a custom solid roller 434, Dart Little M block, Brodix T1 M2 heads 227, crower 6.0" rods, JE forged flat top pistons, Eagle stroker crank, Lunati solid roller cam 252/252 .582/.582 lift miniram, bunch of other custom shit and he and I had the same discussion. That motor right now is putting down close to 500whp naturally aspirated with an inadequate intake. He and I had this conversation and when he goes to the track, he doesn't bother using 100+ octane. He says the gains are not worth wasting the money for it. He has a good tstat and a solid radiator and says it's fine.

I mean, are you guys seeing people with street-driven cars and motor setups using high octane and having it make that big of a difference? I could see if, like Chad said, you have a motor that is set up to run high octane fuel all the time and that's all you put in it.

Let me put it this way, on your streetable NA car, would you spend an extra 300-450 bucks for a 100+octane tune if you just had minor bolt ons, or even typical headwork / cams etc.? At that point, why not just run a "conservative" nitrous tune instead? :lol:

I'm only saying that you need to run the gas the car is setup for. If the motor was built to use pump gas, then of course you wouldnt see any gains from just an octane change, you wouldn't see any gains on a turbo car either (unless it has knock sensors and you are setting them off on pump gas all the time), but, if the motor was built with race gas in mind, Cam2, Turbo blue, whatever, then it will make more power than if it were built for pump gas, plain and simple. I know 100s of people that can ONLY run 100+ in their N/A motor b/c that is what it was built for.
