Powerboost or RamCharger

[dochawk]

Your Caddy has three gears, 2.48, 1.48, and 1.0.

For the moment . . .

Clearly because odds are it's cheaper to put gas in it at current prices. It's just a basic NA V6 engine that runs on 87. Those variables might change when in the DPRC, but at the same time charging is also more $$ there.

Not just cheaper, but time--waiting my turn for just 100 miles, every 100 miles . . .

You want a DD, that you will drive far less than your classics that have none of the extensive list of requirements that you list for the DD. That doesn't make much sense to me.

I'll admit to a hyper-developed sense of shiny. And if I'm spending this much, I want the extra frills!

You have a very demanding list of "needs" especially considering HUD in trucks is just a year old

Back to shiny . . .

Your Caddy has three gears, 2.48, 1.48, and 1.0.

Just the '72; the others have four, while the '72 has 3--for the moment . . . eventually, it gets the 50/50 gearing swapped for 55/45 with a kit for RVs that used the turbo-425 (and meant for 45/55); it gets reversed here), and then the 3.07 rear end swapped for the 2.73 of later years. At which point, having 2, 3, and 4, a torque converter modified to dual stall to replace 1st.

And I'll still get better mileage towing it with a powerboost than driving it !

I want a 64 Coupe DeVille.

I wouldn't mind that, being the year I was born.

Also the first year for a turbo 400, meaning you can put in a 700R4/4L60 without *too* much trouble to get an override.

But I prefer the 50s and early 70s styling to the 60s.

You'd probably like my '73 sedan deville. I also have a 500/425 out of a '75 eldorado sitting on a shelf in my shop. By shelf I mean pallet racking. Car they came out of ran and drove, but wasn't worth fixing. It was a convertible who's top had been missing for many many years.

 

[dochawk]

on a '75, it should be a 500.

The 500 was Eldorado only from '70 to '75. It's the same 472 that the rest of cadillac had, but with a longer stroke.

In '76, all Cadillacs used the by then thoroughly castrated 500, as the 472 couldn't hack it.

And then down to the 425 as the Great Castration hit full stride.

But a spare 500 is a wonderful thing to have . . .

I'm honestly looking forward to hearing your feedback.

I haven't made it back to a ford dealer (there's only four in the valley, and there's a limit to how many times I can show up!), but I happened to be at a chevy dealer today to get keys cut (for one of my Cadillacs, naturally. Now I have more than 1 key!).

Anyway, while there, I asked a sales guy about the seats on their midsize (Colorado). Yes, believe it or not, the seat base tilting is the single most important thing for me. Really.

Chevy's 8 way tilts (but not their 6 way). I was happy enough that I told him, sure, let's drive it.

It was their 2.7 turbo, they call it turbomax, with an 8 speed automatic.

The turbo lag was most definitely noticeable. And annoying. (OK, that might have been a delayed downshift, too, but I don't think so). The salesman even acknowledged the lag.

Now, I;m naturallyinclineed to believe that chevy is years behind ford, but . . .


(anyway, I'm unlikely to order an F-150 with anything other than the powerboost, in which the electric motor masks the lag. if I was going to go with a plain turbo, I could get the Ranger in a 4x2, or the Colorado in a 4x2 supercab [but they don't seem to have a rear seat delete . . . {OK, an f-150 crewcut with rear seat delete and locked internal trunk would really catch my interest!}])

That GM 2.7 actually looks really good on paper. And supposedly was designed to take a beating. But I haven't ever driven one and on-paper doesn't always play out in real life.

I had a 2016 F150 CrewCab 2WD with the 2.7 and honestly never felt like it lagged.
The Powerboost's only lag is really those circumstances under low load where it's lagging in its decision to be ICE or EV. Pretty noticeable if in normal mode and putzing from a traffic stop.

In Sport or Tow Haul, the decision is already hard coded to be ICE with electric torque blended in. It's so amazing when you are driving at a relaxed pace. It's like a quarter horse underneath you that is obedient, but you can feel that it's READY for the spurs. ?

It'll spoil you. Feels so effortless.

leaving the dealership was straight on to Boulder Highway, full of lunatics, so I had heavy throttle right off . . . and it quite definitely lagged (unless that's really all it had! Which wouldn't be enough).

But, yess, the PB is the biggest thing drawing me towards the F_150 rather than something smaller.

Yes, the engine out of my '75 eldorado is a 500. The transmission is a th425, which is the fwd transaxle. All cadillacs in '75 had the 500, last year of the 472 was '74. Interesting note-dyno tests have shown that a later low compression 500 only makes around 25 hp less than an earlier high compression 500. Now, this is without breathing through the catalytic converter, which as you know, was the earliest and most restrictive type gm ever made. When that's factored in, the '75 and '76 500's were severely hamstrung.

On that note, one of the many Caddies I've owned was a '74 Sedan DeVille... Def a beater.

Yep, a true barge. The '74's had a 1 year only weird piston. I can't remember what the oddity was exactly, but there was something unique to that year in the shape of the piston top.

Definitely a barge. I thought my '60 Coupe DeVille was a barge. The 74 was even bigger, lol

This is my first ford, and I like my 3.5 Ecoboost. I'll probably even go to a powerboost next. No comment on turbo lag because I love my turbo engines, previous car was a tuned GTI.

With that being said I think I would go with the ramcharger if I could afford it, especially if you can charge the truck at home.

It has (supposedly) more power, payload, towing capacity, speed and the interior will probably have better build quality.

On the turbo lag... Correct me if I'm wrong but I think the GM 2.7 is a single turbo where as our EcoBoosts are twin turbos. I may be wrong here but, I thought one of our turbos was designed to get rid of lag on the bottom end? Yes / No / You're an idiot?

Honestly never really felt much if any lag. That being said, I'm not an aggressive driver.

There really isn't any turbo lag on the 3.5. It's got twin parallel turbos of equal design. Nothing special on that front. If you want to try and experience where the turbos kick in, go into manual mode and keep hitting the up button while slowly increasing speed from 30 mph and when the truck finally accepts 8th gear (assuming 3.73s) go WOT. You'll find where they start to come alive.

The turbos are pretty small and anything over 3k RPMs going into WOT has enough exhaust to spin them right up. You never feel it because after you're out of first it always shifts into the power band.
