E-diff 2wd quicker 1/4 mile?????

...can't sleep...was thinking....

wondering if I put the e-diff fuse on a switch.....

launched the truck in AWD and after it left and shifted into 2nd, flicked switch.

would the 1/4 mile inprove with less drag etc..etc..?

It wouldn't be worth doing unless it would give you a solid tenth.

any thoughts?

Also was wondering, if I did a small e-diff heat the rear tires up slightly burnout....
.....and then left it in AWD with the back tires stickier than the fronts, what
would happen?

....also, for arguments sake, say you had a slick even on just the back, and
it more or less dead hooked and the truck was in AWD and a hard launch...
What would happen?????

Would the front burn harder, like a rear that slips posi, and burns the tire
with the least resistance? interesting?

2007 Red Rock.... slightly modded, but BAD 2 the BONE!

I am not sure how much the power is used up with the FWD on. Most of the Power is to the rear till there is slippage. If you follow my directions its easy enough to install the switch. Give it a shot and let us know!!

wouldnt putting it on a switch keep it from shifting like when you try and dyno with the fuse pulled and it wont shift out of first.

I don't think you should switch from awd to rwd while in motion. I believe it can damage your drivetrain. I remember someone before asking about that. Hmmm let me search around........

I know with my F350 I had to get out of the hole in 4x4 then i would switch out for the driveline loss but that is a true 4x4 system, unlike ours.

I think using the 2wd mod to heat up the rear tires isn't a bad idea.

What about just running the whole run in 2wd. TBSS's come in a 2wd version, and many guys pick these because of the less rolling resistance and difference in weight. TonyGXP has gotten his truck to go 12.6-5 on street tires with simple bolt-ons in a 2wd TBSS. I think you may be faster if you learn how to launch it.
