Im no expert by any means, but I would want mine up to temp (at least the 170 or more) before I rev it anywhere near redline. Keep in mind the 2013-24’s are designed to do so. Unless you have modded to over 800-850 whp when dyno-ing, it should be fine. My 2 cents are: I wouldnt over rev all day, but I would want it up to temperature before running it hard.
No not remove it lol. The safety feature Ford has set in the tach area, the red line that starts at 6250rpm and will go aways once the cars engine temps reach 170* it will move that red line to 7k. But I would never just start the car up and do a pull cold start that is common sense, but I feel it sitting on the dyno idling waiting for 170* engine temps is hurting the potential for most hp, and yes talking about dyno pulls nothing else. Goal is to be north 800whp
I wouldn't be taking your engine much higher than 6k with 800+whp on stock rods. My 2013 GT500 with a 3.6KB made 827whp at 6,100rpms.
I think you are right on that note, because the car is just sitting and a shop fan cannot pump as much air as when the car is scooting down the road. Pick a cool day if possible to get all you can out of the dyno if thats your main goal. Let us know what it puts out!
Very true, I just did not know if tuners disable that feature or not thats all. But if we need to let it sit until engine temps rise so be it. I think middle of May in upstate NY should be somewhat cool but we will see.
Yes we talked about boost and pulley selections etc. But the way I drive the car is worth for me to push it to limit. I do not drag the car, just an occasional street pull or race and shut it down. So I requested the hottest tune Lund gives and want to achieve 22psi. The car has less restriction parts than it did with the old 2.8 setup.
It seems like you're equating engine/coolant temp with IAT2, which are very different. As I understand it, timing is pulled ("hurting the potential for most hp") based on IAT2, not engine/coolant temp. Moreover, 170' is about as "cool" as I'd want the engine when asking it to output max power. Finally, 800RWHP means you're pushing over 900HP at the crank. Like @2011 gtcs, I wouldn't rev beyond 6K at that power level - based on what I've read, you're tempting fate.
I've also read reports of these engines failing during "an occasional street pull or race." It does not require consistent abuse, but only pushing "the hottest tune" too far once, to permanently damage your engine and 22psi is a lot of boost.
