[QUOTE="Paul., post: 15522729, member: 156070"] Boost is a measure of restriction, not volume or blower RPM, ergo it's less meaningful as a basis for comparison. That's why I asked for pulley size. The 3.75" pulley is advertised as 10-11 psi, not 8 psi as you stated above. Of course, removing restriction can reduce measured boost level while increasing power. The point of all this jibber jabber is simple... There seems to be a lot of implication that the 15+ cars make zillions more horsepower than the 11-14 cars simply because they're magical. There is a certainly a difference in power, but it is not as dramatic as some of the implications I've seen made here on the forum. For example, my 2011 GT made 591 rwhp with: - 100% factory exhaust, driveline, everything - 3.75" pulley - 91 octane tune from Whipple - 7000 rpm limiter - airbox lid removed Comparing that to a 2015+ car that makes 672 rwhp with longtubes and full exhaust and 93 octane is not an apples-to-apples comparison. The newer cars will make more power since they make more power normally aspirated. - 2011 Mustang GT makes 412 hp - 2014 Mustang GT makes 420 hp - 2015 Mustang GT makes 435 Given that the 2015 GT makes 5.5% more power normally aspirated than a 2011 GT, it will predictably have similar gains in an apples-to-apples comparison under boost. Also, the 2015 motors have stronger internals, allowing quite a few folks to run smaller pulleys (6.625" and smaller) with more boost, which makes more power. 93 octane fuel allows for more timing than 91, and more power. Obviously, longtubes and full exhaust will have a big impact on power. Finally, this doesn't even begin to take into account environmental factors or different dynos. All I'm saying is, if this thread is intended to be used to get an idea how much power will be made by adding a Whipple to your car, look deeper than just the peak numbers that everyone is proud to share. That's all. Paul. [/QUOTE]
