Awd slr ?
Starting line ratio is just the mechanical advantage you see when leaving the Starting line.
rear gear x what ever gear you leave in.
Example....4.10 x 2.48(1st gear 4L80) = 10.16 SLR

In THEORY can a AWD vehicle handle more starting line ratio the a two wheel drive vehicle?
So....I guess I will add more data to jumpstart the conversation. I take these statements as common knowledge for setting up the car to perform optimally, but help us understand the SLR battle.
~Tire height
~Trap mph
~Converter slip/ lockup
~Trap mph
~Trans final ratio
Once we've established a "best" rear gear ratio, now comes the trans "1st" gear ratio question.
Based on power, weight of vehicle, rpm range of said power, powerband (peak or broad), tire compound, converter design...etc. We can start the hunt for the optimal SLR.
~My question is, is SLR just what the max coefficient of friction limits of the tire ?
~Can the acceleration continue to increase as long as we do not over come the friction limits of the tire?
If that is the case, would an AWD combo stand to handle increased SLR based on 2x the rollout of the rwd vehicle?
~The Rpm drop back based on trans ratios is a huge deal.
Lugging the motor down/ knocking the wind out of the engine is a big concern.
And we get how rpm (boost) and suspension also contribute to SLR behavior.
I'm looking for thoughts and feedback...even theory.
I do understand that a lot of "the correct" SLR is trial and error at the track.
