So, after reading on the Forced Induction forum about how much boost is safe to run on pump gas, I have a question. If you can run around 5lbs. of boost(roughly) on a stock motor with 93 octane, why couldn't the factory engineers have tuned the stock motor to run on 87 octane? If aftermarket tuners can deal with the increased cylinder pressure using pump gas, it seems that a N/A motor could run on 87 octane, even with 12.5 to 1 compression. I realize that there would be a loss in power, but technically it should be able to be done, right? And yes, I realize its a sports car, and yes, I like all the power I can get, and I don't mind paying for Premium, I was just wondering if its possible, and how much power it would give up. Any tuners ever try this?
