id guess OP is around 3400 lbs with driver. at 371 rwhp and with these cars having around 17.5% drive train loss, thats 450hp. trap should be around 118 mph but its not. traps at the moment are showing about 330 rwhp or 400hp.

Well, considering his first trap speed of the day was 107mph with a 14.4, does that mean he magically gained horsepower for his final run? No, of course not.
Physics is much more complex than you make it out to be. If he's not accelerating due to poor traction, then his final velocity is going to be lower than it could be if he had excellent traction. A 2.3 60 ft time is abysmal and clearly a traction/launch issue...certainly not a horsepower issue. Just remember that those 1/4 mile calculators you find on the internet are way oversimplified and don't account for all the little details like gear ratios in each gear, shape of the torque band (remember torque accelerates a car: not horsepower), coefficient of drag, cross sectional area, air viscosity, shift times, number of shifts that must occur, etc.
It would be nice if @1slow370 would put up his time slips so we can see all the metrics. That will give us a better idea of when he finally gets enough traction to actually put the power down.
Also, I have zero investment in this project, other than seeing what this motor is capable of...it never ceases to amaze me. I wish my car had VVEL. lol
