Ford V-10 Performance Upgrade?

[edge68474]

Thanks Arch. I've always thought that, dual exhaust equals better performance, that is, true dual exhaust. Although, some years ago, some exhaust guy proved otherwise. I don't recall all the specifics, but I still think if you take the exhaust from one side of the engine and run it straight back, and do the same to the other side, would very much help to get that exhaust OUT of the way much faster than combing sides to one single exhaust. Just makes more sense to me, and probably to all of you as well.
I look at the corvette exhaust these days and I see 4 exhaust pipes, at least out the back end. Not sure what happens in between. But being a Corvette, I'm thinking their are 4 complete systems, like in, dual, dual exhaust. Things to ponder. Thanks gang.

Yes straight back is the best and that's how mine are and were on the 1/2 ton.

I've seen some that were tied together at the input of the muffler and then separated out the back of it. Didn't make much sense to me.

I don't think the engine turns enough RPMs to take advantage of scavenging, i.e. the velocity of the exhaust in the pipes will actually suck exhaust out of the cylinders.

So the best you can get is to unrestrict the exhaust..

The three valve has a decent exhaust, good size manifolds, large exhaust pipe.. It does do some wierd bends that can add flow restrictions..

On the very early two valve (mine_) the manifolds were restrictive. The Y pipe was reasonably good, but them Ford screwed it up.. There was a "flutter" sound in the exhaust, to cure it, they put a restrict pipe in the "Y" pipe. Eliminated the flutter but cost 5-10 hp..

Long headers will help, I just installed them on my old 2 valve. I should pick up a few horse and also eliminate the broken exhaust studs. (And it sounds like a P51)

Large dual exhaust offer little improvement over a LARGE single exhaust unless you install an X pipe before the mufflers. The positive and negative exhaust pulses need to be available to all cylinders. Gail Banks has proven the exhaust pulse theory and his systems do very well with a large single exhaust. His upgrade for the W series 8.1 MH chassis is a large single exhaust system. The length of the headers determines at what RPM the scavenging works. Thus long headers for our MH engines.

Sounds like a P-51. Where do I get it!!! LOL.
Hey Waiter. I love the sound of a recip starting in the morning. I was on the Lexington many years ago.
This conversation is getting more interesting. So it looks like a Banks exhaust system would be good, a cool air filter like in K&N maybe, then a 5 Star Tune. What ya think??
Thinking on air filter intakes, in Arizona in summer, cool would be out of the ? in my mind. Now I watch Street Outlaws on TV and see them adding ice to some container. I wonder if it's possible to say, have an intake to the filter from your MH cab's air conditioning. I wouldn't think it would be that hard and, would it be worth doing??
Ok, your turn. What do you think about my ideas my good friends?
& at the same time.

Here you go, Workhorse with twin turbos, I believe Jon from Ultra RV posted this picture

STOP! STOP! You gotta stop that LOL. That looks so COOL.
I would like to drive that once!!!
Isn't UltraRV the same as Brazels, I think so. I live very, very close to them. Maybe I should ask who has that MH, hmmm.
Hello Friend. May I drive your MH?? LOL.

Yes the same company, would be interesting to talk to them about this, not sure if they had anything to do with it.

Jon is on the WH forum often

Would also like to drive it

Any V-10 that gets 5 mpg at 62 has serious mechanical/drivetrain issues... and not in a good way. The difference between 55 and 62 is not 5 mpg, more like ".5" mpg. At 55 my 2012 E-350 V-10 is turning right at 2,000 rpm. At 62 it is running at 2,250 - 2,300.

Over the last 5+ years and nearly 50K miles we have consistently averaged 9.5 mpg cruising between 55 and 65. This includes a little generator time and we usually run at or near our GVWR of 11,500.

When I started towing my motorcycle with an open trailer it cost another .5 mpg and now my new 10' cargo trailer costs me another .5 mpg {the bike and trailer weigh 2,220#}. Out on the interstates I run between 62 - 65 as anything less than that gets spooky and the worst mileage I've seen is 8.5 towing the cargo trailer and bike.

[edge68474]

Well then I feel good carrying approx. 7000 more pounds and getting 7.5 MPG. It would be nice to squeeze a little bit more out of it without taking the fun away.

The Banks exhaust and intake plus a 5 star tune would sure help.
I doubt if you would see any improvement by having the intake inside your motorhome. Then there is the intake noise you would have to contend with as well as the smell of gas when you shut it down.
Now what about that twin turbo system , that's the way to add performance. I bet it would bolt onto my old 454.

Wow, that's exactly what I was suggesting. Cool.

Very happy so far. Noticeable difference on my ‘16 Miramar 33.5, towing a Ford Explorer.

About the performance in the hills: I leave it Tow Haul and take it off cruise so I “control” the engine speed. I let speed drop because it’s just not worth listening to King Triton singing at 4000 RPM for too long.

As everyone on this thread knows, thinner air kills performance on a gas engine and we’ve done some slow climbs. A few times we unhooked the toad until we got over the hump and down a bit on elevation. So we are clear, I’ve really noticed the drop in power when we are climbing up over 8000’. Gas engines are what they are, freer breathing or not with the Banks system.

Given that I prefer to drive at 70 and I’m towing, I haven’t bothered to check gas mileage before and after Banks. In round numbers, with Banks, 70 MPH while towing 4500 lbs costs me 2500 RPM. The engine estimates my range at 550 miles per 80 gallon tank....On the flats between Illinois and Colorado. 😎

[edge68474]

If your engine is correct, then you are getting. 6.8 MPG. That's not bad doing 70 MPH and hauling 4500 LBS, in my view.
