RE: New Chevrolet Trailblazer

GM currently has issues as well with the DOD system taking the cam out in V-8 engines. I thought that by the 2014 model year they had that figured out. I did the AFM delete on my truck and didn't notice a difference in mpgs.Not sure of the affected year's my independent mechanic had his go out and he replaced the entire engine. His daughter's truck is new enough that had the same issue but is being repaired under factory warranty. The son of a carpenter I utilize has a Suburban that had the same issue. Ford had their cam phaser issue on the 5.4 and GM had the cam issue. Maybe someone can enlighten us if the issue is resolved and what years are affected. Updated in 2014 and up. Shouldn't be an issue.

RE: Rated engine power

" Every DYNO event I have been to the Stock Cummins nets about 85% of advertised HP. Sometimes a bit more. That's in part because the intercooler is out of the picture. They make a big difference! WHY is it out of the picture? Not much different than on the road with a big fan blowing at the front. I've only been to a few dyno events but none ever used a fan - do they sometimes? It would take a big one. Banks uses an elaborate setup of 40 HP worth of electric fans a bunch of ducting for dyno runs. Anything short of that isn't going to move enough air to make a difference IMHO. You are in Bothell? I have used 3 different Dynos in this area. I have always seen a fan used. I have been to about 25 dyno days. I can't imagine not using one. Come to Auburn and watch my Caprice get Dynoed after I install the cam and headers. Those fans make a difference. :C I met my wife in Bothell, she grew up on Whidbey Island.

RE: Rated engine power

All manufactures rate horsepower at the crankshaft when it advertised. It is full accessories and emissions. Not exactly. Especially for those who use J1995. J1349 is used by the manufacturer who makes the completed vehicle while J1995 is used by the manufacturer who does not. For example, Cummins uses J1995 because they only sell engines and do not make a completed vehicle. You are right, I should have been more specific. I was thinking GM, Ford and Mopar. When they advertise cars it is at the crank. I would assume it is the same for the Diesels, but I never really thought about it.

RE: Rated engine power

All manufactures rate horsepower at the crankshaft when it advertised. It is full accessories and emissions. Cars in the 50, 60, 70's were rated with no accessories. That is why if you were to test them today you see they are lower than was advertised and slower then what they should be for rated power. On average when you do a dyno pull in a manual you expect a 10 to 15 percent loss through the drive train. In auto 15 to 20 percent loss. This is average and it varies case by case. I will use my WS6 for an example. It was rated at 320 to crank by GM. It dynoed at 328 bone stock. Underrated by GM. You hear about that one on a lot of cars. It also depends on what kind of Dyno and conditions that day. The rated HP from the manufacture is done in controlled conditions and has to be repeatable.

RE: New Ford 7.3 V8

Just one more I can't let it go, please help me My 11 second 2000 WS6 Cold start. Cold start video Fuel injection is the best. :) Ok I am done. Looks to be Trans Am with those honey comb tail lights is the tell tail sign of a LS engine under the hood. Yep 2000 Trans Am WS6. Heads, Cam, intake, headers, Ford 9 inch, Mcleod twin disk clutch and a bunch of other stuff I am forgetting. Dyno tuned at 440 RWHP. It will get out of it's own way. :) 68,000 miles, half of those a 1/4 mile at a time. LOL (not really)

RE: New Ford 7.3 V8

Yep no one goes into the inner workings of a motor anymore. This is for my 2014 Caprice, L77 (6.0 LS2 Bottom end LS3 Heads) I suspect with this setup and ZL1 Torque convertor the car will make right around 440 to wheels and run mid to low 12s. It is my daily driver. Notice the date they were ordered. I will be busy this weekend. :) Sorry I highjacked the thread but sometimes guys are stuck in the 60's https://i.postimg.cc/KcnW0TZz/20191113-181715.jpg https://i.postimg.cc/D0bMhWGC/20191113-181719.jpg https://i.postimg.cc/mD0G7WN5/20191113-181656.jpg https://i.postimg.cc/6qnx0bM5/20191113-181658.jpg https://i.postimg.cc/KYjVQcf8/20191113-181704.jpg

RE: New Ford 7.3 V8

I miss the old days. They were IMO, what hot rodding was all about. The Chevy SB had so many possible configurations that one could swap things aroung and build a motor such as the 383... A motor that chevy never produced. Those were the days when Hot rodders actually got into the inner workings of motors, porting heads, lapping valves, fitting piston rings. installing cams.... Nowadays most just tap on a keyboard and "tune" a motor... The Tuners never get any grease/oil on their hands. Hard to see that as mechanicing... More like playing a video game. LOL. Come with me on Journey down the road of the LSx. I just ordered all the parts to swap out the Cam in 6.0 Caprice, then I will have to tune it. It requires pulling the heads, new lifters, new valve springs new, valley cover to delete the Displacement on demand. There are plenty of guys doing the same thing you are talking about with the LSx. It is easy and all the parts swap. 5.3 heads on the LS1, 6.0 crank in a 5.3 6.0 in place were a 4.8 was Iron block vs Aluminum block. My LS1 WS6 has ported stage 2 patriot heads. a 228 232 .581 .592 cam, LS6 intake, Ford 9 inch rearend. All done in my garage, then off for a dyno tune. Sir I am going to sound like an AS* but you have been out of the game awhile.

RE: New Ford 7.3 V8

Ok everyone, the big block vs small block debate is ridiculous. Obviously most of you don't know much about engines. The term came from the physical size of the engine, not the displacement! And if we want we can give the triton motors 3 designations, the 4.6 is a small block, the 5.4 is a big block, and the 6.8 is a bigger block. The physical size of each engine is larger than the next! This! The big difference between the 4.6 and 5.4 is the 5.4 block is an inch taller tan the 4.6 but it is still a SBF. In regards to t he LS series of engines. A 4.8, 5.3, 6.0, 6.2 etc is the same size block with a different stroke and sometimes bore. 6.0 has a 4.0 inch bore while the 4.8 and 5.3 have a 3.78 inch bore. The original aluminum LS1 was the same size block with a 3.9 inch bore. LS7 had what I believe to be the largest production bore at 4.25 inches and that is a 427 small block. There are largest displacement aftermarket LS small blocks. Same size block. Same physical size, that is why LS swaps are so popular.

RE: New Ford 7.3 V8

GM 6.6L is based on the small block. Ref link below https://www.google.com/amp/gmauthority.com/blog/2019/02/gm-planning-new-engine-larger-than-new-6-6l-v8-l8t/amp/ A small block will most likely never have the duty cycle of a big block...maybe if they spend tons and tons of $$$ Direct injection doesn’t have gasoline washing the intake port and EGR deposits won’t be washed away Oil sprayed at the piston bottoms a nifty thermal metric Still love my L29...but if GM comes out with a similar big block...WOW...just might get one You really need to see the longevity and mileagae a 6.0 gets vs a 7.4. You would be suprised. Tons of guys are doing it now with no 7.4 or 8.1 to offer. I went from a 1989 7.4 to 2002 6.0 to a 2017 6.0. You couldn't give me a 7.4 for free at this point.

RE: New Ford 7.3 V8

^Yeah GM is still sucking wind in the gas HD truck engines, even with the new 6.6. Maybe they'll be under rated, hopefully. Except the 6.4 with outgoing 6 speed never out pulled the 6.0 with the 6 speed. It wasn't geared properly and didn't put as much HP to wheels as you thought it should based off of the advertised power the engine made. It is more about power to wheels and gearing. You can advertise any horse power you want. I want to see real world towing numbers.

RE: New Ford 7.3 V8

Jeeze Louise, big block vs. small block V8! It's not that hard to understand, ladies. Makers would take existing designs, I.e., the existing engine block, and change its bore or piston stroke length or both to increase displacement and hopefully gain power. So most makers based engine designs on few basic castings, like two sizes, hence big and small block terms. Ford, for example, started with a 260 cu. in. V8 and took that to a 302 small block. 390 and up into the 500s were the big blocks. I THINK the 351 was based on the small block but I'm not sure. In GM's case, small blocks from the factory were 350 cu.in. and below. 396, 427, 502 were based on the same engine block. For GM that was sort of prior to the last 8.1 You can now get a 527 C.I. LSx based engine which is still a small block.

RE: Gm 2500HD GAS VS DIESEL

Fact: Diesels get better MPG. With a range of only 200 miles or so, a gas truck needs to start looking for a trailer friendly fuel station very soon after filling up. A big pain in ******** I easily get close to 300 in my 2017 3500HD 6.0. Now my old big block yep, you would be correct, but that was 1989. Depends on how much you are lugging around too.

RE: 1/2 ton or 3/4 ton

Or a better question, why do people obsess over a few hundred or even, say 1000 lbs? If a person has done much towing, they'd realize that towing safety includes many different factors, only 1 of which is the weight of the trailer. And trailer weight (within reason) may be a ways down on the list of important considerations depending on the trailer and the rig. Like I have pulled around 15klbs many times behind 1/2 ton trucks, but it's low profile loads and the ability to adjust the load to get an acceptable tongue weight. BUT, I'd not even consider towing a 7 ton 5ver or toyhauler behind the same truck. Jus cuz it weighs the same don't mean it's even close to the same. Nother example, ultralight, lightly loaded big TC, say 30' long and 6000lbs, not too practical but possible. A JGC or Durango is "rated" to tow more, but that trailer could horsewhip a short lighter vehicle like that pretty easily, especially in the hands of the inexperienced, but it would be far more comfortable towing it with an ext cab long bed 1/2 ton that may not have any more rated capacity, maybe less even. So to err on the side of caution, the bigger the tow vehicle, the better, but it doesn't mean smaller is unacceptable in all cases. I totally agree. I am fine with 7800lbs for the trailer. Most half tons can pull it no problem. Most gassers not a problem. It is the length. That is why I have the 4 door long bed truck. Loaded for camping it is heavier than the trailer. The trailer doesn't push it around at all. My hitch really helps too.

RE: 1/2 ton or 3/4 ton

Why do people list their trailers GVWR? Do people really tow at their trailers max? I don't. I had an 11,400 5er that loaded up weighed 9200-9300 lbs. Why would I want to mislead anyone? Yes. No big deal for me My situation 2012 Passport 3220 BHWE. 6280 Dry. 7500 Gross. I weighed it twice this summer for 5 day trips. Once with my 2002 2500HD once with the 2017 3500HD 3500lbs Dexter axles, empty tanks, two batteries, 2 propane tanks. We travel pretty light compared to everyone else we camp with. Front axle was 3480 rear axle was 3520. 7000lbs You figure 800ish on the hitch. I am a little over. The axles are right at capacity. I have been like that since 2012, probably heavier in the past as we got rid of some stuff we never use. I went with load range D tires this last time vice the load range C it came with. It did make a difference in sidewall bulge and how the trailer handled over bumps.

RE: 1/2 ton or 3/4 ton

Many people view a gas truck with 150K miles as worn out. A diesel with that milage is viewed as broken in. What people? Do you have a Facebook page? I will just talk GM here but over at the GMT 800 board which is HUGE compared to this place 150,000 is just broken in on an LS based gasser. There are threads every week about high mileage gassers. You should take a look if you get a chance. This isn't 1960. I am not saying a gasser will out last a diesel but there are literally 10's of thousands of 4.8, 5.3 and 6.0 trucks with well over 250,000 miles on them putting in work everyday on the original engine and transmission. They have a running thread for gas trucks with over 500,000 miles on them and its a pretty good size list.

RE: 2020 GM/Chevy gas 6.6L max towing test

I wonder if it fails to downshift because at that altitude the engine doesn’t generate enough torque for the transmission to sense a downshift point I wonder if sensors saw high temperatures after miles of full throttle and dialed back the power to save the engine or transmission. In this video and the 2017 gasser video they mention all temps were in spec. But that is just it. It could have defueled or cut power to keep the temps within spec. Diesel do the same thing. The Ram 6.4L did it as well the last Ike run they had. This 6.6L could have forced the truck into lower rpms to keep the temps at safe levels. Right, but that is not a parameter in the transmission field. There are something close to 450 parameters for the 6L80E/6L90E. For the 6L80E and 6L90E time and pressure are the tow big ones. I will hook up the Laptop next time I tow and see. I don't remember reading about or being able to mess defueling in the program. I have HP Tuners. That thing is great if you understand it. It has really woke the Caprice up with the cam swap. I don't plan on messing with the truck at all. It is a great diagnostic tool too. Like I know guys who remove torque management. Not really worth it to me, I don't feel like rebuilding the 6L80E in the Caprice every other season.

I know the Caprice looks at speed/rpms/time/MAF/TPS. I will have to look and see it temp is part of it. I really messed withe Caprice when I got rid of the AFM cam and installed an LS9 cam.
