: Whipple supercharger on a 6.0L or Banks on a new 6.6L Dmax?

Just out of curiosity (and I hope this is the right sub forum for this) which would give me faster off the line times and faster acceleration at highway speed, supercharging a 6.0L or putting Banks on a diesel?

I have an 8.1L 2001 HD and want my next Chevy to have at least the same if not more acceleration (and wish I'd supercharged it back when I bought it).

Which would be better?

From those two choices, a Whipple on the 6.0 would be much better than the Banks. Now if you put EFI Live on the Duramax, that's another story :cool:

Long and short of it. Diesel all the way. I have 2002 8.1L with Whipple/Innercooler. Was very quick with stock pizza slicer tires, but after lift and 37" tires power band is way off and mileage is 9-10mpg at very best. Needs 4.88 gears to be in correct rpm range with 37" tires.

My truck before my dually was a decent 3/4 ton with a 6.0 It made about 450flywheel hp. I liked the truck, it had a cam, exhaust, electric fans, and good tune. It went a 14.2, my dually isn't as fast but I like it alot more. Mainly because I went from 9mpg to 18mpg and my truck has still yet to be tuned. If you want a more apples to apples comparison I would say diesel vs turbo'd 6.0. The turbocharged 6.0 would make gobs of power (and be more like the nature of a diesel) and the 4l80E wouldn't need to be built like the Allison. But you have you buy the kit vs build the Allison. Once the Allison was built you would be able to make 600whp and close to if not over 1k wheel torque. The 6.0 would make 550whp and 625wtq before valve float if not at a lower power and boost level. So you would then need to go into the motor.....that being said. I think the diesel is a winner because major componants save for the tranny don't need to be replaced until around 700whp when the turbo and rods become suspect. At that point you would have a very heavy truck in the low 12s or high 11s with traction. Plus you would have the durability of a diesel and the mileage to boot

6.0, diesels are over rated

I would go with the Dmax. the 6.0 is a half ton motor. The 8.1 was a lot better pulling motor then the 6.0 is. now if you bore and stroke your 6.0 to a 408ci and then put a supercharger on it then......... but if you are going to spend that much on a 6.0 you might as well just get the Dmax

a supercharged 6.0 would be faster off the line but not faster than a diesel if you were going 50mph and smashed it. If you drag race go with the 6.0

Don't forget you'll need to buy premium fuel to boost a gas engine, unless you run water/meth injection which still is another tank to fill.

Super charge the Duramax. Get the best of both worlds. :D

Dollar for dollar the gas motor will cost way more to build, vs. a simple tune on a diesel, not to mention the better gas mileage the diesel will return. But if your rich and don't care, go for whatever rocks your world

duramax with efi and a built trans which is like 5 grand total will kill any 6.0 L with just a simple supercharger..ull spend more money in trying to bore or change gear ratios in a 6.0 than just putting a tune and a new tranny in a duramax

I just got rid of my supercharged 5.3L and got a duramax. I would go with the duramax.

If you realy want a fun truck to hot rod get a half tun with the 6.0, if you want a more practical rig go diesel. they will probably both be pretty close to the same performance per price as far as drag racing.

Diesels are too expensive and unreliable at high horsepower. It is cheaper to build a 6.0 that will run 10's and last compared to a diesel that will run 11's.

what are you smoking?? lol you're saying a gasser is more reliable at high horsepower than a diesel??? thats a laugh. And a duramax will come off the line WAY faster than a 6.0 with equivalent mods...

yea i wouldnt say the gassers gonna be more reliable. but if your just looking for a weekend truck thats mostly for fun, gassers are a better choice. once you get lower then mid 12s the gassers start to get much cheaper too.

what realy draws me to diesel is just being able to have a streetable,practical, and good fuel mileage high performance truck.

How many 1000hp duramax's last 20,000 miles?

Any issues you have on hotrodded Dmax will ALWAYS cost more to diagnose/ repair/ replace than on a hotrodded gasser. Setting that aside, I'd go with a "modified" Dmax for sheer grins per mile.

how many 1000hp gassers do you see even driving on the street?

Just re-read the original post, my how we've gotten off track lol. Went from a supercharger on a 6.0 gasser, vs. a Banks tuner on a 6.6 diesel, to which one can make the most power for the least amount of money, and how long will it last :lol:

Lets build a 1000hp Duramax and a 1000hp 6.0 gasser and see which one lasts longer, costs more, gets better mileage, is more streetable, and goes faster in the same vehicle. Also don't forget you need to have the knowledge in order to build these beasts. VERY hard and expensive experiment to do no? Its all speculation...

So a whipple on a 6.0 and banks on a Duramax. They should run exactly the same, and cost the same. Duramax will get better mileage but you have to buy fuel filters and sometimes fuel additives. The 6.0 will have great throttle response.

You will pay for either. Big power costs and no duramax is going to hold together over 700hp so go and yell all about that but a 1000hp max costs bigtime and goes thru inside parts fast. The gasser could be built less for a bit less power and have alot of fun. Gassers today whynot the LS9 is what on top and look at the power that gets. I think you have to look at the new gasser kits for what you can really make for the dollar. Diesels just cost too much after a certain power level for most. Like any power deal.
