Thread: Hybrid Vehicles

Well I guess you got your reasons, I have had turbos in every truck I’ve owned since they were available, so far no trouble in any I’ve been around. Some of the little cars that have them now have enough power to actually keep up.

Got a guy I know who just done a rebuild on his 6.7 diesel, put 3 turbos on it, dyno had him over 1100 hp

I’ll do some research, didn’t know anyone having problems with them

Well, I got around fine the last over 10 years with a car and a 2.4 litre engine. That got me to both coasts and back at least once and had enough power to pass on a 2 lane highway when I needed to. The same should do me going forward as I don't need the extra power a turbo would provide and saves me the extra complication of another part to go wrong.

Years ago I had an 85 Ford 3/4 ton diesel with no turbo and it couldn't go out of it's own way if it tried. I bought it to pull a 24 foot camping trailer and would not buy a diesel truck today without at least one if not 2 turbos with the same idea in mind of pulling a trailer. That was also the first and last Ford I ever bought. It was not a great experience.

Great thread to read, and I’ll chime in as I have a fair bit of metal halide and lipo battery experience.
Electric, fully battery powered is not a winter friendly means of energy as well.
Specially lipo batteries hate the cold. Tesla has large heaters in the battery banks that use energy just keeping the cell banks from freezing, but they don’t have ac to keep them cool, yet.
Their range is significantly different in sub zero conditions..

Hybrids are a bridge design that are weaker than either technology as Glen pointed out.

Turbo technology is a fantastic way to get maximum ooomph and mileage out of a gasoline engine without constant heavy consumption. Only when you ‘step on it’ do you really suck the fuel. When light throttle is used, very efficient.
2 biggest things I’ve seen people do that kills turbos and gives the tech a bad rap are low grade fuel use, and shutting down hot.
Gas turbocharged cars must be fed 91 octane minimum due to the enhanced compression. I personally only run 94 in mine. They will run on 87 but not well, and there will be damage over time. People don’t believe that and are cheap so put in regular gas.

And turbos spin at over 10000 rpm so their axial bearing must be lubricated well. When people come to a stop, they shut right off, stopping the oil pump from pumping so oil flow stops and the turbo bearing spins down in stagnant oil which gets hot and breaks down. So always let your car idle, for just a minute when you park and you will double, or triple the life of your engine.

Hope this helps some. My personal choice in today’s technology is a turbo charged engine for the best balance of economy, environment, and personal enjoyment. You cannot beat forced aspiration for maximum response.
Cheers.

The 6.7 Ford stock is running around 470 hp and damn near the same torque. My 40’ Rv doesn’t even slow it down, set the cruise at 75 or 80 up and down hill but off road when that turbo kicks in if it will grab it will go thrust mud right now. I would say there’s not many people who have more experience in trucks, lived i. Them 7 days a week for months on end locked in 4 wheel sometimes for weeks off road then leaving them running for days on end. If they couldn’t do the job better than others I didn’t buy them. At my last position I authorized the purchase of 1100 pickups. Yes I could have a Prius but that wouldn’t even haul my wrenches, but if I did a turbo would make the little baby car go . Like has been said you can buy what you want and it will do the job of your situation. In my situation it wouldn’t even get out of the driveway. Heck I got my wife an Armada Platinum with 4x4 and a v8, makes for comfort going down the road too. But hey if your looking for economy, you could get a Vespa

Exactly my point, if you need one go for it. I no longer have a hankering to tow a trailer around Canada to go camping so my need for a turbo diesel is gone. If I had a need it would be a turbo diesel because I can tell you a normally aspirated diesel sucks at the job.

Not everyone has a budget that will allow for two large fuel guzzling vehicles in the driveway so the vespa comment is a bit much.

You make some very good points that the longevity of a turbo is dependant on changing your driving style re immediately shutting down hot and using 97 grade gas. The average Joe will just keep driving the way they always have and will continue to get trouble with turbos. Nothing inherently wrong with turbos just with the users in most cases.

Kinda of makes you wonder why they equip vehicles with auto stop/start when the engine has a turbo and shuts down every stop light or in stop and go traffic.

Comes down to $$ I think Bob. They could easily add an electric run on pump to the oil circuit to save the tech from the everyday joe during run down. They could add clarity in the manual about octane and compression impact. But hell, the warranty will run out before an abused turbo does typically.

Yes, an electric pre oiler would go a long way to turbo and engine longevity. The pre oiler could also circulate oil to the tubo bearing for a few minutes after shutting the engine down. Since they don't it really makes you gun shy about buying a used vehicle with a turbo.

These things are built to break down. Example: put an external tranny filter and change it every year and your tranny will last a looooong time. Had a work truck. Turbo diesel. Had 290k on original engine and tranny. Ran like a top. Still running too as I know the guy who has it. Simple fix as was said. But that simple fix will keep you out of the shop. And as also was said after the warranty they don't mind you coming in.

Most of the newer have an external trans filter now. As for an oiler for the turbo, most go well over 300 k in miles without issue, you may not need power such as in a diesel truck but the efficiency of an engine with a turbo makes them desirable. As for the 1985 truck, I was running gmc at the time so never had one with the 6.9 yet the international engine was well regarded and the 7.3 offering was and is still the gold standard. What a turbo does to any engine is what anyone wants to boost economy and performance, get good air to the engine for improved burn. You can change air filters to do this but not quite as much. But the fact is if it has a torso it will run better and more efficiently. It’s ok if you don’t like them, it really is but it’s not because they don’t make the product better.
