Are there any AWD dynos that can handle the wheel base of a GMT900?

I doubt it. One, AWD dynos are already few and far between. Two, I saw an article wher a Yukon Denali barely fit (not the XL). Three, if I did find one, I would have no time to get there, nor the money in gas. I can tell you that the 2WD trucks seems to be much faster...

It does seem that the 6.2 equipped trucks in the 13s with minimal mods are all 2wd. What is the weight difference between AWD and 4WD trucks I wonder? 200lbs? You would think that the traction difference off the line could make up for it but the times I see posted here tell another story. I'm still quite suprised at how badly the 6.2s spin the wheels on the dyno.

I have heard that they are severely detuned, and this is the reason for the ability to have a 100,000 mile warranty on a "400 hp" engine... Even in tuned form, it seems to just drive better.

The drivetrain loss must still be CONSIDERABLE when looking at the guys with headers/exhaust and a tune. I think I've seen three charts posted here and all were in the 36x range. LS3s can approach 400rwhp with those mods. You would think the 9.5" rear and taller tires couldn't make a 30rwhp difference but apparently they can. The fact that 5000+lb trucks are out there running respectable times even taking the drivetrain loss into account makes those achievements even more impressive.

^^ I wish I was one running respectable times. CAI will probably be my last mod to this truck. I already have approval to build a LSx S10, so....

You guys do know that this was Booper's Thread about his whipple right?


Holy off topic.

Well it is going to be another several days. I got a call from the shop today that is doing the install. I guess when he was filling the intercooler there was a crack in the heat exchanger so it was dumping the fluid out. So monday he will have to get in contact with whipple and have them overnight another one to him. Hopefully tuesday will be the day!!!!

WE are DISCUSSING about superchargers on full size trucks, and the effect the superchargers have on the drivetrain, and the drivetrain on the power. If the OP had a problem he would bring it up.

At the same time, he started the thread, and everyone is discussing except for you. All you did was state that we weren't discussing the topic.

Sad day sir. Hope they are able to get it on there.
