Congrats on getting it running again
ho lee sheet:
Datalogging the break-in tune for my tuner, I doubt I'll play that high again, but wow. The sound it makes up there is nuts.
What exactly is that? Looks much better than the sct live link software IMO. Also, I would have loved to hear what 8300 sounds like. My redline is set at 7600 and that's pretty bonkers (and I never take it that far).
lol
mad jelly of that rev range
Curious as to if you're still making power past 7500, however; but that could be very useful on-track to avoid grabbing another gear.
Also, I dunno what longevity is or survivability of my build is up there. Off the top of my head I don't know about oil viscosity for that use, the chain tensioners (I did finally find the part number for the boss ones but dunno if that's even a big deal), the valvesprings (boss 302 VS's are good till what? no one clearly answers that) or the front belt drive (I still have some GT parts on those pulleys and alternator). I'm not scared of a belt shred, but losing a chain guide or valve float do worry me. I'll ask the builders what they think (since they are providing the warranty), but I think unless its proven I make good crazy power up there, it will be a rarely used range. OTOH, the build is stout, and every piece in the rotating assembly shows 8500+ rpm/750+hp use in its spec
It would be killer at miller or the like for some of those corners to save a shift (and scare wildlife for miles).
Sounds like they can't guarantee performance above that but they should hold. Supposedly the GS cars go to 8400 but I've never heard a solid answer on that even when I talked to teams at Laguna when we were there last year. I've seen plenty of in-car footage on YT from some of the racers hitting 8000, though.We should specify that for a valvetrain specialist such as John, Boss engine speeds do not end at the production car's 7,500 rpm. "We have a design guide so that if the fuel shut off is 7,500, we want the valvetrain to be stable to 400-rpm over that in case of over-speed events, missed shift on a downshift, or whatever. [This is to] make sure that if there is a momentary over-speed, the valvetrain doesn't come apart. If you throw a rocker arm or bend a valve--and it doesn't take long to do that under the wrong conditions--then you can lose your whole engine." Told that one of the Grand Am racers had managed to wing a RoadRunner to 9,000 rpm on a missed downshift with no apparent damage, Mark's commented, "I can only warranty it to 7,900, but I'm glad it worked!"

The B3 valvesprings have been designed to handle at least 7900 RPM by Ford.

You can read the rest of the improvements there as well vs. the base Coyote engine. I'd suggest getting the new alternator and drive belt.
Want to do Pavillions this Saturday, early evening? I want to check this thing out now!
Makes sense. I'll know more about what I'm going to do with this thing once I have a dynosheet showing how and where it makes power.
Saturday sounds good.
Sure, find me a road where we can do a blast up third in that area and you can see for yourself what the loud pedal is like up there. Its kinda nuts.
That's livelink, lol.
We gotta do Pavilions when I get my car back!
