The Excursion is only pushing 2900-3100 psi of oil pressure on a full throttle test at full temp after 30 minutes at temp. IPR at hot idle bounces between 22.1 and 25%. The numbers aren't super consistent though. If the engine has been at temp for 15 minutes the numbers check as good if not a touch low. I'm assuming the hpop is the culprit and am planning on an adrenaline.

Am I correct in my assumptions?

What pump is the best with stock pressure demands?

Thanks for any assistance, it is much appreciated!

 

Maybe but not necessarily.

I'd get an air test fitting that replaces the IPR sensor and then air test the system. AFAIK a failed pump will result in gurgling back through the air filter and/or turbo feed so you want to pull the turbo feed line out and remove the oil filter cap so you can listen for those.

 

Are you tuned?

 

Typical I am but these numbers are all from stock.

 

I'd say that looking at the numbers, your on the money. IPR @2500RPM should be 40%, your at + 41%, should be 40%.

Do injector seals and nipple cups as well when you gut it!

 

What are your ICPV's at KOEO? Should be .18 to .25

 

Showing at .21vdc. Note the ICP or "HPOP" showing pressure not running is, I believe, from using the newer style ICP on the old engine.

 

Passenger side were done about a year ago along with new injectors on that side. Will be doing the driver's side with the remaining injector kits I have.

Thanks for the recommendation!

 

Sounds good, I appreciate the info!

 

These are from this evening just home from work and have ICPV in them.

 

800psi is = 1.0v so you have 1.7x800=1360psi. It's calling for 1407 HPOP.

That says you either have a leak or a pump not able to give it... it's a little short. And by your numbers, 2.1% above what it should be.

 

And looking again, highest was 3.0 =2400psi.
So if that's an untuned number, stock pump and that was it.. you either have a big leak or its dying.

 

Wouldn't the 3.0 ICPV correlate with the 2676 psi though? I'm trying to learn as much as I can so please bear with me!

 

800psi is 1.0v
5.0v= 4000psi
3.0 x 800 = 2400

It shows 3.0v as the highest it recorded.
Sure... if 2676psi was maxed.... it's short of 4000psi. Why I asked if it was tuned. Tuning hides ICPV and isn't the true psi.

 

below is the Ford data for the old ICP sensor/engine:
