Powerplant Transplant

22mpg stock
20.5 after 4.10 install
24mpg after bolting on Trilogy with the canned tune (350 RWHP)
17mpg after custom dynotune at Mo's (409 RWHP)
20mpg after Stainless Works headers and custom 3" exhaust and re-dynotune at Mo's (436 RWHP)
 
MyBlackBeasts: Thank you.
Do get 27-28 mpg @ speed with 2.73 RAR if I keep the right foot light and I wanna keep it that way. Must admit HO2S signals can be modified on demand (open/close loop, lean, leanlean)
MPG averages were near identical for the 2005 and 2008 CVs I have owned with similar emission modifications.
EPA says 2005 Linc Aviator Premium Gasoline, City MPG:11, Highway MPG:16, Combined MPG:13. Pimp Navigators are 4WD and weigh near half ton more than Panthers. (EPA II)
2004 Merc Marauder Premium Gasoline, City MPG:15, Highway MPG:21, Combined MPG:17. (EPA II)
2005 MGM/FCV 2005 CVPI Regular Gasoline, City MPG:14, Highway MPG:20, Combined MPG:16. (EPA II)
2005 -2011 MGM/FCV Regular Gasoline, City MPG:16, Highway MPG:24, Combined MPG:19. (EPA II & III)
2008-2011 MGM/FCV E85, City MPG:12, Highway MPG:17 Combined MPG:14. (EPA III) [Yup.]
Tend to have better highway and worse city MPGs. Burn 89 or higher octane fuel only.
4.6L DOHC and SOHC have near the same MPGs. Arduino will better manage 91 octane fuel timing and duration. Believe I can maintain current highway MPG and much improved city with a DOHC. [!TORQUE!]. But 91 Octane is 10 to 15 percent more expensive and our refineries are in Kalifornia. [UGH]
Sometimes you get what you pay for.

Another issue is exhaust systems. Aviator / Navigator are 2.5", Marauder is 2.25", GM / CV are 2.0". New cats, H-pipe, mufflers and exhaust. That's $2,000+ I will never see again.

Way too much money, time, and effort to throw at a 10 year old mass produced sedan. Throw nitrous and a tune at it and use the power when you want and the gas mileage when you don’t. Done.

No NOx within 150 miles and I have no idea what argon would do.
Have been on the bleeding edge of horsepower technology. Been there, done that, got the t-shirt. Problem with this particular Panther is low end torque [2.73 RAR]. 4R75E will shift into OD @ 1050 RPM / 45 MPH as it should. Speed past peak torque curve in 2nd gear near 80 MPH. Don't need more HP, just more FT/LBS (I own a 2005 CVPI with 3.55 RAR for giggles & grins). Don't wanna be quick, just fast.
Thought Screw All This and called ADTR. Price is more than engine rebuild, swap and tune but is market appropriate. Chris recognizes my voice. Supercharger kit works with 2011 Panthers, no problems. BUT, Vortec V3 is on back order and intercooler thermal exchange coating will take even longer. 39# fuel injectors are hard to find and expensive when you do and Chris has two spares in stock.
So, this has me spinning in another direction, electric supercharging. Much more efficient. Northern Europeans have been using them for years and the Chinese are starting to. Found Duryeatech 24 VDC units which may be the best in the world. There will be some engineering involved but that's what I do.

Huh!??

Argon???

Surely you must know that it is an inert gas....it's a great way to put out a fire....not so much for aiding combustion.

Precise observation. Seems argon liquid to gas is endothermic but not as much as NOx. Adding argon gas increases air densities and combustion temperatures and reduces CO, CO2 and NO2 with cooler exhaust temperatures. Seems HO2S sense less exhaust O2 and ECUs / PCMs advance ignition timing. Diesels have been doing this for years using the same throttle risers, injectors and regulators as NOx systems. Plus, it's cheaper.
Seems argon is not a catalyst and, as it is inert, is not consumed and is recoverable in a closed loop system. Not long ago, at an unsanctioned event at an undisclosed location somewhere in Kali, I saw such a closed loop system in a big Ford diesel truck. Didn't know what it was and team was not talking, but the recovery tank, membrane filter (?) and condenser filled half the bed. Truck hauled *ss!
Ranchers and herders 'round here are doing argon welding gas to improve diesel engine performance and save money and annoyance of DEF. They also fabricate superior suspensions from old auto and farm equipment that are amazing.
Yankee ingenuity.

There is more info on da webz but I am now spooling over electronic superchargers.

That is an exceedingly interesting research article! Thanks for sharing. The conclusion is counterintuitive, very cool read. TY
 
Well my engine has lost all of its oil pressure in my Black Marauder with 284000 hard driven miles. Time for a replacement.
Only thing I can think of is Aviator Engine.
Can somebody supply me an exact list of parts I need to change to make it Marauder Compatible.
Shop is Quoting $805 Labor to pull and put in. This does not include items like coolant, thermostat,Oil+ filter, and labor charges to change out the parts
to fit the marauder.
P.S. Silver is up to 214000+ and running strong.
 
Swap over the intake manifold, coolant crossover tube, cam covers, front timing cover, exhaust manifolds, and oil pan. Literally every exterior engine part.
 
Don’t forget, motor mounts, oil pan, pick up tube, flex plate, balancer etc. get it to a long block and swap everything over
