I've had a scenario in the CR7 sim where if you didn't go full power and pitch with a positive wind shear you would crash because of the imminent negative performance shear the quickly followed. I think it was a recreation of the Delta Dallas crash on short final. We barely made it and we did iniatiate the go as soon as we hit it.

We have the Delta 191 model in the sim I teach - again it is scalable from 0-100% as Mooney said. I've never tried 100%, but based on what 50-60% looks like, I'd guess that 100% is not survivable.

I had an encounter this summer that was exactly like my ATP ride. It was in denver on a heavily loaded 200 (of course) and as far as I can tell we encountered a microburst. I was PM and as we accelerated the airspeed paused right around 100kts then promptly flew past v1,vr and v2. We were airborne almost instantly and got the the red WINDSHEAR warning/aural shortly after. The CA firewalled the thrust levers and shortly after we got a significant loss of airspeed. It was everything he could do to keep it from coming back in contact with the ground. We didn't quite get the shaker but I know we weren't far from it. Needless to say I didn't need coffee for the rest of the day!

As our indoc instructor said, you put the engines on pay roll deduction in windshear. I assume he was talking about the "worst case" scenario windshear, where you "rapidly advance the trust levers to the forward stops." AKA, somewhere up with the radar antenna and the yoke just prevented your FO from ever having kids again.

I had severe windshear in the 200 during an ILS. It was worse than anything I have ever been given in the sim. We firewalled immediately, like we are trained, and the plane continued to descend. The plane leveled at 900 feet with our nose pitched up and still firewalled. After riding this way for about 10 seconds we shot up at 4,000 ft/minute just like in the sim.
I have a few type ratings as well and it has always been firewall during a windshear escape.

Old aviation words of wisdom: when in doubt, climb! No one has ever crashed with the sky before.
If you are being trained to push the thrust levers past the detents, do it! Get as much distance between you and the ground until the warnings go away. When the event is over notify ATC and ask them what altitude they want you at. I sure as hell won't be trying to figure out what the best pitch power combo is near the ground. Firewall it and follow the guidance. Remember it was designed to make it as simple as possible to avert the danger!

Several different levels of extremity in the sim, some instructors like to use the max. It's your ride so if you know you still need a W/S e scape maneuver on the PC and you suddenly see +20 kts get the h-e-chopsticks out of there, don't wait for the warning, by the time your pitched up you will have it.
Shake & Bake.
