Why not put turbos on 2500 gas trucks

This is rumored to be available for the 2018 raptor and the shelby gt 500

I hear all these great reviews on the Eco-Boost engine and all the power it creates. Somewhere I read a few years back it had more HP and torque then my 2500 HD gas. Why doesn't Ford or Chevy offer that engine on a 3/4 ton truck or put the twin turbo's on the V8 gas engines?

Because you can get a diesel in a HD pickup that already has a turbo.....seriously.
Sure, go build a gasser that will pull with any of the big 3 diesels and get back to me on fuel mileage......after you get home from your second job to pay for the gas !
Haha

But to your point, Ford has capitalized so well on the Eco boost that I bet they could make money on a 5.0 Eco for the HDs.
Think about it though. As cool as the Eco is, after being out for what 7 years now, there is no talk of any other mfgs doing it.
Even Toyota who offers OE dealer add on blowers hasn't stuck one under the hood before the sale......because it's not efficient enough to the masses.

The ecoboost makes about 85% of it's torque at 1500 rpm.
There is no reason to ever have to rev it out.
It tows like a turbo diesel at low rpms.
Without the trailer, doing about 55 on state routes I can often get in the mid to high 20 mpg's, on some back roads at @ 40 mph it gets 30 plus. Towing it is about like everything else maybe 10 to as much as 13 mpg, depending on winds, hills in Central and north FL don't seem to change that at all.
We've taken ours from key west, to Asheville NC, to New Orleans. Never a hiccup.

look at factory V6 turbo rpm's at said power
then at a standard V8 rpm..

people complain of a V8 at 4,000 rpm's..,now live with a V6 Turbo at 6,000s

fyi, a turbo diesel cooling system can easily handle a V8 Gas turbo.. but the crankshaft will not.

cast crankshaft vers forged.

That rpm level would be for a car not a truck. Look at the 3.5 EB HP/TQ rpms. Peak TQ is at 2250-3500 and HP at 5,000.
Never heard of an EB owner complain about his truck having to be wound out. Most say they love the low rpm TQ.

I agree. They place twin turbos on the Ford Raptor. Essentially an off roaded f150. I have the 6.2l , 6 speed, 3.73 rear. While its good towing 8,000lbs, it does have slow down a bit in the hills. One nice thing is that the new v8's upped the power band and they power up into the 4,000r+ rpm range

For what I do, I even think the 300HP 4.3 V6 GM uses would work in a 2500 truck. Link a 4.10 RA, 6l90 trans.....It would pull my typically 6-8K equipment trailer, sometimes as high as 12K lbs. No it will not be as fast as a Diesel, or the 6.0 gas V8 or equal.......I would have the chassis to do what I want, for the now many miles empty I drive, good mileage, bad when I tow, tell me when one tows and gets great MPG's. I used to do what I do today with a 255HP vortec 350, with a 105hp 292I6, muncie 4 sp and 4.10 gears. Now that were slow!
I do think some of todays more potent smaller motors would be good options for many of us frankly!

Yep. Those 3.5L ecoboost engines look like very capable power plants. They make 425+ ft lbs of torque at fairly low RPM and I think they're in the 400HP range. That's plenty for a gas powered 2500 truck. I too have wondered why that's not an option in the F250.

It might also be buyer apathy. I had a friend that bought an F150 with the 5.0L V8. The TT be bought was too big and I tried to convince him he would have been better off with the 3.5L. 'Nope, I had to have a V8 to get the most power'. There was no convincing him that the 3.5L was more towing capable.

Could it still be there is a significant demographic that just can't believe that a V6 makes enough power to pull heavy loads? I dunno. When I bought my RAM I strongly considered either an F150 with 3.5L or a RAM 1500 with EcoDiesel. Ultimately I decided I wanted a good sized 5er so I went bigger with a Cummins. But....had I decided to stay with a smaller 5er or TT then either of those 1/2 ton trucks would have been perfect choices.

KJ

I'd take one of the 3.5 eco boosts in a 25 series truck! NOT ALL of us need or want a 400+hp motor in the rig. We may only be literally running down the road at gvwr! or towing a less than 5K trailer at max gvw including HW. A properly setup motor, trans, axel ratio to tire diam, and one can get 20+ mpg even in a 25 series reg cab rig in the 5000 lb tare range, run down the road at 10K max gvw, maybe 12-15K gcw doing local delivery etc.......styling!

I was just talking about this at work today. I think a small V-8 wit ha turbo would be ideal. Maybe a 4.7 or 5.0 with 400-450hp, and 450ftlb or torque would be a great motor when you don't want to go all the way to a diesel.

It's proven in the 3.5 Eco-boost to be reliable, powerful, and economical. You get the fuel economy of a 3.5 when unloaded, but you've got the power when needed.

Honda did the same on the CR-V we bought my wife. Went from a 2.4 to a 1.5 turbo, and increased power and fuel economy.
