On oil pressure, 10 lbs per 1,000 rpm used to be the golden rule.
Yep, this has been the guiidelines for decades. Most engines, set up with rod and mains set towards the lower end of tolerances will run at least 30-35 psi at idle when hot. The 15 psi at idle really bugs me - as does the sudden rise to 80 when you put your foot in it; it has to be some electronic nanny artificially dropping the OP via some bypass. OP requires energy, and energy cost fuel. I'll bet racing Mustangs have found a way to defeat the electronics and restore OP to what the engine lubrication system is actually producing.

Or maybe the Coyote has a variable speed electric oil pump? I'll do some research on the lubrication system on these engines.

Basically getting the same. 17.5 psi at idle, and when cruising in 4th at 2,000rpm it's at 30 psi, pops up to about 60 with a bit of gas...

Tx for the link, Bob. Has anyone done this mod?
This is Ford Performance Racing Parts’ Steel Billet G-rotor pump, M-6600-50CJ. It doesn’t deliver greater volume because it doesn’t have to. What it does offer is durability thanks to its steel billet rotor construction and close attention to detail in manufacture. The M-6600-50CJ pump has the Coyote’s standard pump housing, just tougher guts inside.

I put the steel billet gears on my 2015 when the supercharger was installed. I did not do it on the 2011 GT I put the Roush stage 3 on. I raced that thing at least 50 times at Milan in90+ degree heat without a problem. Never raced the '15. Anyway, it ran flawlessly with 600rwhp. And, it was a stick. I think the weak gears thing is a hyped thing, like lots of stuff, to sell parts. Yes, it may break but it is very rare.

Much more common is the issue I had with Livernois Motorsports not tuning my car properly and likely the cause of the damaged piston that was a result.

Gears are just fine. Oil pressure is just fine. Us older guys got hung up on oil pressure because of the poorly designed oiling of the 60s muscle cars. Oil temp tells almost everything and a serious racer would put in a gauge that pulls the temp right off the oil pan as I did on my 2011 GT and 40 years ago on my 427. I'm not touching the Bullitt. It is just excellent the way it is. :)

Tx. i too put a gauge on the pan in my '64 365 vette. Amen to leaving it alone! Ran it today, for an hour in hot humid air. Never got over 210, if I can believe the gauge! But I will tell you that the A/C, never had that on my vette, worked great!

Agree about oil temp; it's unbelievable with the all the gages we can conjure up on the Bullitt's, there isn't an oil temp gage! I'm waiting for some clever person to find a way to delete the silly vacuum gage the center cluster, and replace it with a proper oil temp gage. How nice would that be - oil pressure and oil temp up nice and high, front and center. Somebody must be working on this?

If the oil temp gage was inop on my airplane I would not fly it - period.

18's & 19's have a bypass solenoid to regulate/lower oil pressure at lower RPM's to increase efficiency. Many manufacturers use either a bypass valve, or a variable output oil pump.

Thanks, this makes sense as the changes in o.p. are too dramatic to be anything but artificially regulated. It would be nice to code this "feature" out, and have full o.p as cars have had for 50 years.

A S2B arrived at my local airport yesterday; it was being delivered from OK to the new owner. Old owner made a high-speed 50' pass down the the runway, hit the smoke, 2 quick rolls at 50', and pulled up with 2 vertical rolls before his last landing in the Pitts. I'm at a podunk airport, but this kind FAA hijinks got the locals freaked. 8S1; obviously an uncontrolled field. FBO operator drove my Bullitt as fast as he could down our Runway :-)

I learned acro in a Citabria> Super Decathlon> S2B at Santa Paula CA

Just buy the center gauge cluster from a GT350. Less than $250, pops right in, plug and play on the connectors, has oil pressure and oil temperature. Only thing it doesn't have is that MyColor isn't supported. It stays white-on-black all the time.

The temperature is calculated from operating conditions, not via a sensor. Still, that's the same way it would do it on the dash if it was available. And, damn it, it IS available as an optional display on the analog gauge dash in the EcoBoost and base GT.

Done! I just ordered one; thank you!
