i guess it depends how far your racing i would be pretty confident you will be faster.... untill you hit 97 or 98 whatever it is and your truck shuts down and he cruzes on by

If he had a tune that modified his transmission, he would probably win assuming you're stock. But with just a Diablo and your 3.73 rear, I bet that's a really close one.

 

How much axle-hop do you get from a dead-stop, full throttle launch? It must be worse than in a CC. Could you put the transfer case in Auto for a hard launch? My last two GMs were SDs so I don't really know how Auto on the tcase works.

With the Black Bear Tune you should be able to beat him, I think crew cab trucks are heavier. Plus a Black Bear Tune mods the PCM & TCM way better than a Diablo hand held tuner.

I have to have the traction on to get a good start, if I dont it will brake the tires loose from a dead stop. He has awd so I thought he might loose alittle there.

Wouldn't be advisable to use Auto for a hard launch -- it would continue to rob power all the way through the run. I know it can be shifted on the fly back to 2WD but my experience has been that it won't shift if you're held at WOT.

 

However that does bring up another factor. If the SD is AWD it will have higher parasitic loss of power through the drivetrain, but also will hook up much faster than a 2WD truck.

close.. close enough to say coinflip those 3.73's and your lighter curb weight should do it. I think if you're tuned it would be a full truck maybe trucka nd half for you.. You can launch in 4wd and switch 1 second in and it will not affect you. i do it all the time, in my 2010 Ram and my old 05 F150 when it's raining and i have to take somone from a light or pull into traffic and need to get on it

The AWD will get a better start, but the Silverado will get a better top end.

      Fluid Change Questions

      By Chuck FB · Posted

      I know when I was looking around last year to see if someone handled Amsoil gear oil to buy at the retail level which of course means full price. I found an independent shop that works a lot on GM/Duramax pickups and they did not bring in the 75W-85 as they just stuck to the 75W-90 for the front and rear as a standard practice for the HD trucks which makes sense anyway for the higher hp/torque diesel and pulling heavy loads in four wheel drive. I haven't changed my diff oils yet but still plan on using the 75W-85 for the front diff as I highly doubt I will be beating on the truck and figured for my use type the bit thinner oil would be to my benefit for the winter for that slightly less drag. Very different weather here all winter vs northern Washington near the coast, that's for sure.

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      frustrating P0446 code

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.
