IMO the seat of the pants meter doesn't register till about 20hp, it is in fact a a guestimation. But my Oh sh!t factor is pretty accurate And if my little ecam, that doesn't even have a .500 lift, .498 to be exact, is putting out 280rwhp_320rwtq on racer Brad Brands dyno at Atlanta Chassis Dyno, it's the addition of my personal Oh Sh!t factors that make my gt40p, ecam, cobra intake put down the numbers they do. Just from those dyno numbers with an ecam should tell ya "Hey, some truth to this is VERY possible". Cause I'm showing numbers on a Dyno from a racer where his sh!t has to be perfect with his turbos and set ups. It's not a run of the mill shop, it's what they do, they race. And my little ecam numbers should make ones LQQK at the Oh sh!t factors. So that's what this forum is all about, providing experiences with trouble shooting and ideas. There's my idea, my experence and my numbers to back it up from a true racer's dyno. If anyone doesn't like it, believe it or whatever my dyno sheet is on the sticky with the name, number and address of Atlanta Chassis Dyno. http://www.stangnet.com/mustang-forums/threads/guess-my-h-p-the-dyno-1-4-mile-time-thread.677534/ Also there are TONS of videos from Brad racing at events on youtube. So I've laid down my little ecam numbers with actual hp numbers and actual torque numbers and have proven my case for actual Truth, what YOU got to present your case? ....Other than "Nawww, just can't be." Maybe it's more torque, i dont truly know, but my Oh sh!t factor is dyno proven, take it or leave, Free Country ...whaut WHAUT!!!
