My goodness, I just saw this post:

Bisimoto got a bigger graph and went with it, but I strongly suspect (READ Know) that his methodology was flawed and his results well within the error of probability.
He didn't account for Alternator Load. He ran his Baseline COLD and his Test Run HOT. Didn't have a proper Cooling Fan. I suspect he used Correction Software, which is usually an average of averages - inaccurate. And I suspect his Weather Correction was Software-based and not from an actual Weather Station in his Garage. He took his numbers from a Run through all the Gears, not just the conclusive 4th Gear only where the Gearing makes the ratio of Rear Axle/Crank Rotation almost 1:1, and on and on.
All these things have their effect. Adding 1% error here and a couple % error there and pretty soon, you accumulate error equal to, or in excess of, any reported gain.
People will believe what they want to hear (Placebo Effect). Bisimoto is the only person to report a gain by de-snorkelling (in both HP and Torque), in the Known Universe. So for those who want it to be so, it is so.
But, this falls far short of a properly conducted test and I for one remain unconvinced. The only thing which is conclusive here is the old addage: Garbage IN ... Garbage OUT...

Jim, I am sorry to say, but you have no idea what you are talking about. LOL. I am tired of biting my tongue!
A weather station (which I have 3 in the shop)? Alternator load? Proper fans (3 again)? Garbage in~Garbage out? This is insulting. How dare you attempt to discredit my years of research, academia, hard work and equipment? Based on your nonsense, we should never dyno test, or event venture to explore powergains less than 50hp!
Bottom line is this, you do not own a dyno with the proper equipment...you were not at my facility to see how my tests were conducted...you even cannot see the simple fact that our 2.7~3.2+ litre engines are fed by a restrictive orifice, with a primary goal of noise reduction.
I performed a test that no one else cared to do...not to have results yield HP gains, but to explore the outcomes, and educate. I experiment quite a bit, and things that look good on paper, rarely work: 19% of my experiments on our race cars do, but when they work, they work well.
I have world records in the competitive performance arena using my "flawed" dyno as a testing tool.
I use 4th gear in all of my pulls, Jim, and Chaudanova can attest to this as well...you really need to stop attacking me!
By the way, if you performed dyno tests, you would know that a cold engine produces more power than a warm/hot one (denser air mixture) not the other way around. Get off of your high horse, and contribute positively to this board with facts/results not fairy dust.
