[QUOTE="05 Roush, post: 1964394, member: 10919"] Turbochargers are completely different and have different characteristics. And the phrase "pump gas" is relative. Pump gas can be 85,86,87,89,91,93,94, and 100. You will see many T/C applications that require premium fuel aren't running any more than 14 psi. Some motors can take more of a beating, and therefore are designed to run at higher boost levels by the engine builders. I doubt this is the case with the Terminator motors. If Kenne Bell is convering their asses, why not follow suit and do the same? If you read his information carefully, "throwing boost" around is not the best solution. I'm not trying to scare anybody away; I'm trying to get people to THINK before they mod. Nobody said more boost was bad. But think of the paradox. More boost. Then leaner A/F. Same octane. Hmmm. Guess we better retard the crap out of the timing so we don't detonate. Wouldn't it make more sense to boost less and retain timing and A/F with higher octane ??? It'll certainly run cooler! People should be deeply concerned, not "scared", if this is their only means of reliable transportation. Unless they really understand what's going on they won't be able to make intelligent choices regarding the risks to modding their motors. If you don't think it's a risk, by all means fire away! If you understand the risks and are willing to pay, fire away! Remember, it's your car! If this is your toy and can afford to break it (not to say it will, but one never knows), FIRE AWAY! There is simply no replacement for octane. PERIOD. You're better off making the most HP at lower boost levels than going the [i][b][u]easy[/u][/b][/i] route by simply adding more boost and leaning it out. Cooler air and higher octane makes a denser charge, and the engine produces more power...safely. Sure, you can run 12.1 A/F @14 psi, but I would highly recommend using racing fuel. At least 4-5 gallons per fillup. It's a good insurance policy, and so is running richer at WOT. I firmly believe that it would be a crime to see these cars blow engines before they get to 100K miles, and would rather do sensibly safe modifications and leave the real aggressive modding to a fox body where 5L crate engines can be had for $700 a pop instead of $7000. But that's my opinion. I'm finito with the thread. Apparently, I've hit some nerves. [/QUOTE]
