4.5L Supercharger??

[nakman]

Meh, you guys can have 'em. 91 octane isn't getting any cheaper, your fuel economy gets worse, I don't exactly use the top end on the trail and you're going to have to wait for the other trucks on the run at the top of the pass anyway. I'd personally rather have OBA and a burrito cooker. And if the day comes to plunk $5K under the hood why not go with a Tundra V8, or Duramax diesel, or something else that gives you a much bigger bang for the same or similar bucks.


And Corsair in order to fully implement the Romer plan you have to sell your 40 to me, so hey let's talk in a year or two buddy....

reffug (on Mud) had a turbo'd 80 that came from Colorado. A few months ago, he fell asleep at the wheel and totaled his truck. He has the crunched truck sitting in his driveway.

He just bought Clownmidgets (On mud) turbo'd 80 to replace it, so he will start parting his wrecked truck out soon.

He says the turbo and engine is in great condition.

It's easier than getting a SC right now.

Interesting note in that thread is post #11:

LC has had my supercharged 80 at their shop since October. They tore it apart and are tooling it to be reproduced. They are also adding some other goodies to it as we speak.

The rumor about the overseas contract is not correct even in the slightest. If you call John in the r&d department he can tell you all about it.

I was chatting with Chris Wood (ex-ARB guy) about turbo vs. supercharging...He mentioned that he has driven both versions and that the turbo charged rig seemed "smoother" and faster. The problem I have with a turbocharger vs supercharger (aside from the cost difference) is IMO a turbo has to "build up" pressure. At least that has been my experience

So with a turbo you get a surge of power after say 2000+ rpms but with a supercharger the power should be more linear, correct?

That is true ...Ok, 2 years. Funny, my aftermarket warranty expires in ~2 years and realistically I'm guessing I can't do anything until then anyway unless I want to void the warranty. So, start saving your pennies now

In my dad's turbo'd 80 it takes a little over a second for the turbo to fully spool up when you mash the pedal - you get used to it. On the trail I could see, on delicate obstacles where you need precise throttle response, that it could be a detriment, but he's rolling on 33s with no lift and has topped out at 18mpg doing mostly commuter-type driving, but not stop and go. When I drive it though, I just can't help but put my foot in it I get probably closer to 13 or 14.

Romer - reffug's didn't happen to be white and lifted did it?

True....SC's are always spooled which means you get boost as soon as the load hits 0 atmospheric vrs chargers that have to spool up once load hits 0 atmospheric. Turbos can pack more air because it's easier to cool the charge vrs chargers that create more heat by design and are more prone to heat soak. Short story....SC's are immediate gain but can be inefficient at higher R's while turbos lag but keep on boosting until motor blows! Which is better? Depends on what you want....low and mid range linear surge with moderate top end or sharp and steep torque curve and beastly top end?

Lifted yes, white no.

I think it belonged to someone named Tony about 4 years ago here in Colorado that was being sold through Christo.

And how it looks now. Jamie fell asleep and ran straight into a pole. Anyother vehicle and he would have been dead.

I had read about the accident but I had not seen any pictures...Reminds me of the pics of that guy on MUD that ran into a crane at like 60+ mph, and lived.

 

[subzali]

There are SO many of those stories (there's also a guy on MUD that ran into a stakebed that peeled the hood back)...I'm pretty sure there's no substitute for Toyota engineering. Read IdahoDoug's descriptions of most of those accidents and you'll see how well 80 series trucks are thought out.

turbo lag can be addressed by currectly sizing the impeller, using dual stage, and or pop off valves and boost filter/regulators.

Straight six motors with automatics are awesome for turboing. most people go bigger on the turbo than nescessary.

You can lesson the lag by speeding up the spool time or lessening the boost but the fact remains that when 0 atmospheric is reached the bypass on an already spooled SC closes or a waist gate on an idle turbo opens. Linear or lag!

I said addressed, not cured....

Turbo is still better

For diesels and Tuners maybe. Hey Treeroot.....

Dino needed some help out of the 80s

Hmm, cool news. This one Sarah will have to break into her savings for

 

[corsair23]

$4K

Power doesn't come cheap anymore...I assume to that you can probably add $2-3K in engine PM work (HG etc) and be looking at a real world cost of $6-7K all said and done. Maybe I don't hate going 30 mph up the passes while towing all that much
