What size pulley? What exhaust mods? (if any) What RPM is the motor being spun to? Is it 91 octane or 93 octane?

stock pulley that comes with the kit, (8# of boost I believe)

Full Stainless Works Exhaust - Longtube Header w/ no cats, to SW Catback

Dyno sheet shows pulling to 7k.

93 octane

Whipple kits come with different pulleys. What size is it?

Is it 91 octane or 93?

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.

I agree with everything you said sir! Well put!

That's awesome! Gettin' after it!

My best is 11.65 @ 125, shifting into 5th on my 20" drag radials with a 1.9 60 ft. I'm hoping that with my new 3.31 gears (to be installed Sunday) and 17" slicks with skinnies I can get into the high 10s. That'd be more than enough for me. :)

Here's my car

2.9 front feed
3.75 pulley
ARH LTs no cats
Corsa sport cat back
Sai Li FS
PBD tune
E85
OPGs/CGS

The timing is conservative but made 734/562 running the car to 8k

Just had mine dynoed last night. Running 9.5# with 91 octane. Stock block, headers and cats. MBRP 3" H pipe and race series exhaust. Full suspension.

Yup. That's him. He still has the Lemon too. I doubt very much that he'll ever get rid of it.

Is he on facebook? Id love to get back in touch with him. He did a few of my cars gears and if he still does stuff on the side I may need him to do a couple other things.

Ordered the Whipple Stage 3 Boss 302 kit. Totally stock Boss minus side exhaust baffles. Any guesses what it will put down with the 3.65 pulley and the Whipple tune? Whipple claims 750 crank but we shall see.

I don't doubt you'll get there. I'm around 700 crank with a bigger pulley at 5200' elevation.

Cool. I'm a little hesitant on using the smaller pulley with 93/BAP. I picked up a 3.75 just in case it runs lean when I datalog it.
