Tapatalk should have never been dropped.
Anyway, I have about 2k miles on mine now. Absolutely no issues to report, and the car comes out the hole pretty damn good.
I run MMR NA grind cams (comp). Unless you're going max effort, I wouldn't touch the cams on FI.
If you're seeing valve float, then it may be worth looking into upgrading to custom grinds, VCT lockouts, and valve springs.
Moving to 4.11's and dropping down to a 26" tire worked wonders for my setup.
My setup makes power in a pretty similar way to the 5.2 due to the VCT deletes and 9k redline. The only difference being that the MT82 has a slightly better gearing spread than the 3160. It's a shit gearbox, but at...
No doubt, like I stated above, VCT is huge for low and mid range torque and subsequently, power. I was going max effort NA, and wanted to turn more RPM than what I felt the phasers could handle. I make peak power at 8,600 RPM, and expect that peak to climb higher after a few exhaust and...
With those mods, springs, VCT deletes, and MMR s2 (comp grinds) I'm spinning mine out to 9k. That's why i skipped over the NSR cams completely, wasn't worth the money or effort involved for small gains.
The redeeming factor of NSR's is the retention of full phaser use. This will help reduce...
For what this car makes still on untouched heads, they do flow very well. I doubt they'd out flow the boss heads, but probably aren't very far off. Ford did a very good job on these engines, with the exception of the OPG's.
There can be slight CR loss when the bowls are reworked, but anything lost would be gained back when the head is decked.
Highest ratio shelf stock piston I've found is 12.5:1 from JE. I plan on running these when I do my full build.
