Here are the goods:
ALL BRAND NEW(unproven!)
C&C solid block
4 3/4 stroke
Peterson 3 stage pump with -16 feeding it
sae30 wt oil
Jeff Johnson wet sump pan
raised the front to insure we had enough oil to the pick-up
I tore the engine down to check all bearings, all are fine. we have not raced the engine yet but have let it idle and reved it up tuning our Big Stuff 3. I also recorded these same reading with the BS3

what type gauge do you have elec.or manual if elec it may be gettig interferance some where and check oil filter or change it and see if it helps might be something wrong with the filter I had problem one time with my 351c not sure if it was the oil gauge or the filter i changed both at the same time but it quite after that not sure if that was the problem or not but it never did it again it started after i broke it in after i changed the oil

Rod ,

Something sucking air? Cracked / Exposed Pick-up? Loose Hose or fitting?

Thanks I like it here allready! I sold all my Chevy stuff!! Back to Fords where I belong! But htis this one is kicking my tail! Changed oil filters and oil filter mounts to a Peterson becuase it has more concave to it per Carrol Carter, no leaks or cracks that I can find! I recorded it with the Big Stuff3 and watched the guage no luck!! Thanks guys all ideas are welcome!!

Pump Adjusted Right? Everythings new right?

yes sir, adjusted psi up to 65 and down to 30(averages between the bounces)
Every thing is brand new out of the boxes(that always scares me!)
Sent pump back to Peterson they replaced the spring , piston and back of the housing, SAME result
Jacked front of car up with rear on ground to run the oil back to the pick up in the pan SAME result
disconnected the scavaging from the bottom of the turbos and let them drain freely SAME result

I have talked to Peterson the oil pump provider in detail and they have inspected the pump.
I have talked to Jeff Johson the oil pan fabricator.
I have talked to Carol and Chris Carter the guys who make the block.
It's gotta be somthing that I did stupid!! I just wonder what???

Thanks again everyone!

Rod,

I believe this was asked already but are you using an electric or mechanical gauge?? maybe some kind of rmi iduced noise coming from the bs3 .... just a long shot ,,,have you tried a new gauge ??

both an auto meter mechanical and a 0-150 sensor on the BS3 data logger,
Thanks

It turbo charged? Take the turbos off and see if it still does it....Could be something with the seals.

Same thing if you running a vaccum pump...... Take it off and see if it changes.

The turbo removal from thesystem is a good idea!

I just got off the phone with Carol Carter and he told me to DRY SUMP it and be done with it! SOOO that is what I am going to do! These things take so much oil they have the largest oil galleries I have ever seen!
SO thanks everyone for the ideas I will keep yall updated!!

we put a Moroso dry sump pan, a Peterson 5 stage oil pump and a dry sump tank on her , had to change some intake plumbing, but oil pressure is steady and good, these blocks just take so much oil to run properly I guess! But she is fixed we are trying to test this coming weekend at Farmington to ready for the ADRL in Rockingham! Tough first outing I know, right!

Any pics of the installation?

i know this is a done deal now but do you think oil restrictors to the turbos would have helped the problem?

I did not ry that by recommendation of the turbo company, We did take the car out this weekend for the first time on the third run we spun our way to a 4.69 @159mph weighing 3000# on 10.5s!

Very nice car........... Keep us posted

Sweeeeeeeet

I assume this car is on meth? Very nice!! We need some video of this thing! I'll be running EFI meth on my 640" BBF, but with MFI from Alan Dudley.

Holy Twin Tubed Dryers Batman! That's freakin' AWESOME!!

I was about to say wow in reference to the killer twin turbo set-up. Then Damon's old retired batman on a bike pic made me forget all previous thoughts...
