So.... For those asking whats up with the mushroom clouds.....
I present you with the build specs for what
@snoranger has dubbed the "2.9 Trinity"
Pistons showed up! and from what I can tell, they fit PERFECTLY.
Just in case someone goes looking for another set... Ford part # DR3Z-6108-A, even though the piston tops are etched "DR3V-6110-AA"
Set of pistons came out of a 2013 Shelby GT500 Mustang with the 5.8l Trinity engine. Engine detonated with 2,000 miles on it due to what looks like a wiring or injector fault. eBay find. Heh.
Their loss, my gain. Long story short, they work in a 2.9l.
Plan of attack is to use them as-is. I did think about changing rings, but..... Nahhhh..... This is a junkyard build.
Stats on the 2.9 Trinity:
SOMEBODY PLEASE CHECK MY MATH!!!
Bore: 3.681
Stroke: 2.835
Rod: 5.400
Compression Height: 1.220
Piston Dish: 10cc
Head Gasket: 0.042
Estimated chamber: 42cc
Deck Height: 8.084
548 gram 5.8l trinity pistons with pin and clips installed
Seems that 302 forged H beam connecting rods (I'll double check these post-machining) fit if shaved 0.002 side to side, and 0.003 off the back of the bearings
Yeilds a 1.9:1 rod ratio on a 1.3:1 bore/stroke ratio with a 7,000-8,000 rpm redline.
Idk about yall, but I'd drive the **** out of that from stats alone...
Need to double check head volumes post-polishing, but compression should be 8.35-8.6:1.
Since I managed to track down full forged internals, I may splurge for once in my cheap-assed life and pick up the T70 twin scroll thats on my Amazon wish list. Planning on setting the wastegate to 21 psi after a dyno run or 10.
As much as I
DO NOT like online turbo calculators.... I messed around with the one at not2fast just for kicks. I stayed relatively conservative with my inputs.
BUT
At 7000 RPM redline with full 21psi manifold pressure:
Good enough for me.
Keeping in mind that online calculators are usually inaccurate, at 7,000 RPM and 21psi, this is what it came up with...
If I wind up with HALF of that, I'll be running through the streets nude in celebration.
If its within +/- 20% as it claims to be, I will kiss each and every one of you on the mouth.
Yes, even Will.
Hopefully I'm correct on all above factors...
If not? Well, the trinity name will hold true when it turns into a mushroom cloud.
