In any case.....I'll let you know **MY** results.

On Friday, I'll be doing a baseline dyno WITH the mid-length runners and then an after dyno with the full length runners. If the full length runners provide a sufficient torque bounce below 4K RPMs.....I'll keep them on the car.
In any case.....I'll let you know **MY** results.

Keep us posted. Looking forward to seeing the results

What’d you come up with?
#27
Uhhhh. Your oil pressure appears to be a bit low during that pull in my opinion based on what I have seen. Find out what pump is in it.
#28
Its a pump that tony recommended and supplied. I believe it’s ported, and it’s my understanding that these lifters reduce oil pressure. That being said, I do plan to add a half quart to bring the total to 6.5 quarts.

Let us know.
I'm curious to see this.
This is something I am thinking of doing too.

Well.....I did half of it....and it was pretty much a fail.
For the baseline dyno, the CPU pulled 7* of timing. Peak power came in at only 482HP at the wheels....and power topped out at 5400 RPMs when I should've been able to pull past 7200 RPMs. The tuners suspect gas that was not up to par.
I'm having the shop do more work next week, but they've already installed the longer runners. I'll get a couple of runs in with the long runners....but I can't see how it will correlate to anything meaningful without a decent baseline.

Looking into it I’m beginning to think I may have an oil pressure sensor that is not reading correctly or possibly an oring not sealing properly on the oil pump.
#34
I've seen oil pressure in normal LS3 engines at 950 RPM under Hot idle @ 16 psi +- 2/3
as RPM increase so does Oil pressure .
And besides I think Tony Mamo knows what he's doing .

got a ported throttle body in the mail just yesterday from tony. Going to try and get it installed this weekend. Have 25k on the build now and still running extremely strong with zero issues. Still trying to find someone that will actually fix the o’ring on the oil pickup. I’m almost certain that’s what the issue is.
also trying to decide on tires. I don’t want a drag radial, but I do want better traction. I’m seriously leaning towards the r888r. Anyone have any experience at these power levels with those tires?

I put a set of Kumho ecsta SR91 Tire’s on mine this spring. They hooked better than the Nitto NT05R drag radials that I took off. High performance summer tires. Have a base coupe and set was $700 mounted and balanced.
