thanks.

Performance wise it should be 2200 lb less than typical Raptor. That should also help MPG somewhat too. MPG wise it will need to be on 91 Octane numbers drop fair amount on E50.
Big difference for HP numbers (at least noticeable) Is my tire wheel package is under 50 lb per corner while Raptor wheel/tire typical is over 100 lb.
Will not know until I try though as think the 9" Ford axle uses more hp than the 9 3/4" Raptor version.
Huge disappointment if it does not make at least 500 RWHP on 91.
Only mods from stock are minimal each. More of a direct Ram Air for airbox, Big change in exhaust that is very similar to the 2021 Raptor. Garrett says only around 13 hp gain from cooler although here it may be more in hot summer but again I have no clue about airflow through engine bay.
I have seen other trucks make 575 at tire so figured a 25 gain with just the 1/2 weight tire wheel combo. Gearing may make a diff too. I can also run in 7th gear which is 1-1. My tire height is only 27" and am running 3.50 rear gearing.
If I look at what my other eco swap truck did it ran 13.0 @ 105 with base engine and tune only it made 420 RWHP and track weight was 4750 lb that truck I had to leave at idle or it would just spin. Much better and larger tires on this one. Adding 150hp and taking away 800+ lbs of weight should get me to 11.50's. If It will make 600 RWHP and I can get it to hook and leave on boost it may net me a 10 second quarter mile. Not sure how the engine will hold up to that HP level (Pistons/Rods) All I want is a long distance cruiser that has acceptable performance, MPG and long distance cruising. Truck looks decent and is reliable.
So goals are from past experience with ecoswap. I think just the tire size alone will be huge for MPG, weight and other factors should be huge too.
Is your Raptor around 40 mph per 1000 RPM? Mine should be 36 mph per 1000 RPM.
65 mph cruise should be around 1800 rpm
Taller final gearing, bunch more weight, huge tires combo and a much much larger truck. Will soon find out I guess! What ever it is will not be the 6 mpg I was getting with the BBF.
For distance I will have 46 gallons of fuel capacity and at only 20 mpg its 920 miles cruise per fill.
