The relays are usually rated 20A/35A at rest/energized.

That sounds odd. Is it maybe a lost in translation and they just mean the silicone bead?

Sigh

Just did a pull in 3rd recording the rail pressure. As soon as I get into the pressure steadily drops to 52psi and stabilizes there. I'm guessing it's around peak torque when the ve starts to drop.

Looks like a flow issue after all...

The regulator is a Vette style(new). The pump is an aeromotive 340 from around 2011 with maybe 8k on it. Based on what I was seeing the pressure was jumping a lot (6psi max) based directly on what the injectors were doing.

I'm not certain if the pump is going or I need to do a return style system.

Guess this is one of those walks and talks like a duck kinda things.

At WOT the computer is in open loop for fueling meaning zero correction from commanded.  It gets what it gets based on MAF reading, or SD calculation depending on how your ECU is set up.  The factory method is fuel spray is commanded open loop based on MAF reading.

No MAF. Running SD.

Deff running OL in both of the logs though.

If the injector flow rate was the same as before but suddenly now the car is reading lean you have a few options that I can think of -

1: The car is making more power
2: The O2 sensor was wrong then
3: The O2 sensor is wrong now

1. Odd but possible I guess. Not likely though. It is from Europe to Texas now. Not a big if any altitute difference.
2&3. Only at WOT? All else was still in agreement. There has to be a flow issue I'm not seeing. I need to check rail pressure again.

Also need to pull a few plugs. It did 25hrs from Delaware to San Antonio with the tail in-between. They should read pretty accurate.

A little different. 3rd vs 4th but same RPM and same VE cell. There are some differences in flow. Not sure if there is enough to make it go that lean.

Pulled out #6. Looks a little hot. In the Netherlands I had to run a 5 heat range(98ron ~93). Maybe I should go back to a 6.

Don't think I've ever seen it that bad. Grease could be the issue but you may just have to chalk it up to a hard life.

I do. I need to verify again as I haven't looked at about a month but I believe calculate flow was the same prior to me adding to the ve. After adding to the ve the flow went up. I could test the injectors individually again but testing 8 at once might be difficult to get a proper simulation of RW flow.

I'll check the logs tonight.

Two sensors. One for each bank and they are in agreement. There is only the header gasket and one v band between each sensor and the engine. I checked to make sure they were all tight. Even pulled them apart looking for soot leaks. Nothing. :-/

Thanks for the input guys. This is why I'm at a loss.

50% or so. They are 525cc but I flowed them at ~600 at 4 bar.

Thanks!

Just have to fix the lighting in there now.

Before I went to Korea for a year the engine was pulling about 108% on the VE at peak torque. Now it needs over 120%. Not realistic for my motor.

Obviously I'd think the fuel pressure was dropping but it's a solid 58psi the whole time. Injectors are spotless. And I just calibrated the o2's. It has the Bosch 4.9 sensors. LC-2 WB's.

I even checked the valve springs.

The issue is only at WOT. Any other time everything is fine. Any ideas?

Car is finally home and absolutely filthy.

Need to do a lot of organizing still.

I've also an upgraded t-56. Redline D4 for normal temps. D6(little thinner) for cold weather.

I've tried just about every fluid out there and the D4 was the only one that was really nice. I still have one more to try. AC Delco Syncromesh.

Mobil 1 almost felt like the blocker rings didn't exist when cold.

Are you planning one set for all three chassis? The pics look like an FC.

I'm curious how much ground clearance there will be.
