I agree with the weight loss, I usually see about 1/2 sec a lap per 100lb minimum.Thanks all for the feedback. After reading through these, weight reduction has become high on my priority list!
Some good news, my desire to make this car as fast as possible and a great opportunity thanks to Cortex means I will be doing 3 things, two of them at once:
1.) Weight reduction (targeting about 100-150lbs of weight loss)
2.) New front and rear aero (my current aero setup is definitely on the weaker end)
The above items will be happening at the same time thanks to my fantastic friend and fellow racer Tri-bar. I should have very good back to back data.
3.) And the cherry on top will be a Cortex cambered rear end along w/4:10 gears. It's on order, but I am not expecting to get the cambered rear anytime soon, so I should be able to provide good before and after data on if the 1.5s-2s claims I have seen are true. I sure hope they are.
Front aero is also very important with the mustangs so that is also a good choice.
However I would deviate and get rid of the 3V before I put the cambered rear in (but since you ordered it run it!!) The 3V just has no torque, and without putting in large bores and sleeves it never will. I would change to an LS engine (or Coyote to stay Ford), even with moderately more horsepower the difference in torque will give you a bigger drop in lap times than the rear end. Also running 4.10s with the 3V is asking to blow it up if you are still using the TR3650. You will be well out of useable RPM at Willow Springs and the fast Buttonwillow configurations unless you have the 0.81 fifth gear (or a T-56.) I have settled on 3.73s with my car, seems to work best for all the SoCal tracks (with TR3650 and 0.81 5th,) when I didn't have the Cortex suspension or the 0.81 5th the car was actually slightly faster with the 3.55s then 3.73s.
I'm currently hunting for an LS3 to put in my Cortexed S197.
