Over the weekend I was over at a buddy of mine's customs shop getting an HID ballast replaced & was talking about his EVO & my AWD Fusion Sport.
He was telling me how from stock the EVO's AWD system is likely very similar to our AWD Fusions. FWD with a 10-20% kick to the rear wheels only when needed.
What I found very interesting that he was telling me was the ways he used to route power to the rear wheels close to 50/50%. We didn't get too deep into all the ways he did whatever it is he did, but brought me to the curiosity of "hacking" our AWD systems to gain more %/power to rear wheels or full time AWD?
Anyone feel free to pipe in with any thoughts. Just found it very interesting that he(and many other EVO owners) "hack" their AWD systems to gain performance and/or power to the rear wheels.
No, I've never had an issue with our AWD system either. Just got me thinking if the EVO crowd can "hack" their AWD systems, why couldn't we?
I'd absolutely love to see something near 50/50, but he was saying even on his EVO, essentially tearing down the AWD system, still not true 50/50, but close.
I'm curious what it would do to mechanical components in our AWD system that are built for 10-20% power to rear wheels only rarely, having them running 100% of the time though...
Yeah I'm sure there's a way with enough time and money. But I think you would run into reliability problems like you mentioned.
That's a pretty big bump in the amount of power going to the rear wheels. Makes me think about those AWD components too. Plus your gas mileage would drop significantly running AWD all the time.
My only fear in this whole situation, being a Ford Technician, Ford PTU's arent really meant for that kind of power handling. ive seen a couple blow out and take the transmission case with them. unless they make an entire rebuild kit for the internals to bump them up a notch in reliability, i would honestly let this idea free from the mind.
And this is why No one makes parts for the fusion. No one is willing to even try anything. I would be willing to bet the issue with the strength of the rear drivetrain is very close to the same issue the Speed6 guys have (same AWD system after all). A company makes the parts to fix it. There is guys putting down 6-700WHP in Speed6's. Why? because the took the time and did the research and tried it and figured out what works.
I'm not sure how "rare" it is to get the AWD to transfer power to the rear. The other vehicle I have is a 2014 Edge v6 AWD and in that model they put the infographic for the intelligent AWD torque distribution and I can tell you on dry pavement accelerating straight from a stoplight it transfers torque often, not rarely. At least for the 6F50 it is...though that's not our transmission. Suppose I should hook-up my datalogger and prove it one way or the other some day.
Oh I'm sure it's pretty often, especially in low traction like snow and ice. I think it does it a lot in dry weather bc the car can launch like a bat outta hell.
I know it definitely helps from launch. My 07 2.3 would spin tires nearly half way thru 2nd. The sport just takes off no hesitation whatsoever.
