CaliChevyV8 Posted July 6, 2006 Report Share Posted July 6, 2006 I have a '06 V-MAX with 4wd AUTO, 4wdHI and 4wdLOW. I'd like some advice on using my 4wd capabilities at the track. I've gotten good and bad answers for this from a few people. Some say: Launch in 4wd then switch to 2wd to perfect your launch, and reduce friction while in 2wd. Only use 4wd in dirt, using it on the road will ruin and damage your truck. Do the whole race in 4wdHI. Thanks, Kyle Quote Link to comment Share on other sites More sharing options...
tawss04 Posted July 6, 2006 Report Share Posted July 6, 2006 You can run in 4high, I did in my 97 Z71. I'm stuck 4WD now Quote Link to comment Share on other sites More sharing options...

I'm stuck 4WD now <{POST_SNAPBACK}> Do you know why people would tell me running it in 4wd on surfaces other than dirt will damage it?

Bowtie70SS Posted July 7, 2006 Report Share Posted July 7, 2006 What is the difference between that and AWD? As long as the tires are the same size and turning the same speed what could it hurt. I'd run the race in 4HI...your superior launch will compensate ofr any extra drag. Dave Quote Link to comment Share on other sites More sharing options...
CaliChevyV8 Posted July 7, 2006 Author Report Share Posted July 7, 2006 Someone told me the difference is because the 4wd has a transfer case and when you drive in on the street the stress put on the transfer case is bad? I'm only goin off what I've "heard" though. I'd like some mechanical info if anyone has it Quote Link to comment Share on other sites More sharing options...
misterp Posted July 7, 2006 Report Share Posted July 7, 2006 As long as you are driving in a straight line I can't see anything negative running in 4-HI; you only get differential action if you are turning or have major wheelspin (traction) issues.

CaliChevyV8 Posted July 7, 2006 Author Report Share Posted July 7, 2006 What about 4wd-LOW? Quote Link to comment Share on other sites More sharing options...
StealthSS Posted July 7, 2006 Report Share Posted July 7, 2006 Its okay to drive on pavement in 4wd as long as you don't make significant turns. Hmm, 4-Low...that might get you a 45 second 1/4mile? Quote Link to comment Share on other sites More sharing options...
WI_Dave Posted July 7, 2006 Report Share Posted July 7, 2006 What about 4wd-LOW? <{POST_SNAPBACK}> NOOOO!!! Quote Link to comment Share on other sites More sharing options...
CaliChevyV8 Posted July 7, 2006 Author Report Share Posted July 7, 2006 4wd-HI it is!! That'll probably help my times alot. My scan gauge is showin that my 0-60 times are in the 7's I must be doin somthin wrong Quote Link to comment Share on other sites More sharing options...
ssfromsd Posted July 8, 2006 Report Share Posted July 8, 2006 Yeah the guy at the lights always looks at me crosseyed when he tells me to heat up the tires, while the supercharged C5 was covering me in smoke... Ha we love the bracket racing. Quote Link to comment Share on other sites More sharing options...

Sum 1 Posted July 8, 2006 Report Share Posted July 8, 2006 Autotrac= enables front drive as the rear wheels lose traction 4 HI= enables full lock of front and rear (produces crow-hopping and not recommended for dry pavement use) and can be used at highway speeds 4 Lo+ enables full lock of front and rear designed for extra low end torque (getting unstuck, launching a boat, etc) NEVER DRIVE AROUND IN 4 LO As for the drags, when I've tried using 4HI from the line I consistanly run .3-.5 seconds slower. That's the main reason I bought the V-Max is the transfer case. I only use 4WD when I really need it. otherwise it's rear-only. Quote Link to comment Share on other sites More sharing options...
HDMLNIUM Posted July 8, 2006 Report Share Posted July 8, 2006 I use 4hi at the track and haven't had any problems yet. 13.20's at just over 100 mph in 4-Hi in the 1/4 mile and 1.8's 60' times. Not to bad for running in 4-Hi, give her a shot and you will like it... Bill Quote Link to comment Share on other sites More sharing options...
rgp6373 Posted July 9, 2006 Report Share Posted July 9, 2006 i have some friends with done diesles and when they launch hard in 4wd it bends or breaks tie rods and axles in the awd the transfrer case has slip and the power is more smoothly put down kinda cushons the blow Quote Link to comment Share on other sites More sharing options...
