Heavily modified? The Meth kit (which is probably hurting power btw) is the only mod I would even consider to be in that category. Full exhaust system, air filters , wastegate actuators, intercooler pipes and couplings, BOV and a reflashed ecu? Running 10.80's in a 4000 pound car? 
With over 100 launches on the car already and now cutting a 1.51 60 foot time this tranny may allow John to run 9's next year with a BPU++++: bolt on turbo kit and an intercooler upgrade.

dude, meth injection is like running race gas. A car tuned on meth is like a car tuned on C16, except better because meth cools off the engine. Now that explains how the car ran what it did. I was actually thinking it was a freak car. lol

LOL!!! We call that APU (Advanced.....). I know the "pluses" are fun to add. Yeah this car is definitely pushing mid-600 whp. No where near the 570.

well, I'd venture that the 570 kit is without meth tuning. With meth, like you say mid 600's easy. Makes sense, since I have seen meth kits in supercharged mustangs and evo's make easily 20% more power and torque. Even without tuning, I have seen these kits make 20-40 ft-lbs. The stuff works.

Issue is that the formulas you are using include some baseline/calibration constants and coefficients that make the formula work accurately only for a certain class of cars/conditions.
HC's response:
WRONG, AWD decreases trap speeds as does a better launch. Notice that Johns fastest ET is not his highest trap speed. This is very common. RWD and AWD cars of the same kind will always net higher trap speed in the WRD car due to less weight from the additional components and less non-aero drag.
This is drag racing where powershifts, sometime clutchless are common, no different raping a manual than a GT-R tranny that is planning on breaking anyways if you launch it.

I was only making simple points that neither AWD or LC increase trap speed, unless, like in the case of the GT-R, the VDC has to be left on which limits power to the wheels.
And a RWD GT-R would still trap faster.
You dont actually mention any formulas, more like factors, and they are imprecise.

You are missing the point (as usual) which is that the car has extensive modifications over an already substantial power gain kit. This car is easily making mid 600's or more so it's not losing power from the Meth. Good reasoning seems to be out of your reach.
Take any turbo car and tune it and you can add 60-70 hp easily, and we all know the GT-R is somewhat underrated, likely up to a little over 500, so you're already looking at near 600 hp. Add the exhaust, intake, EBC, wastegate controllers, etc etc etc, and you should get the point. And you can still increase power with meth to safe levels without a dyno tune, so you are wrong, it is not likely that he's losing power with the meth kit.
The fact is that he's making lots of power and is on drag radials. and a 128 mph trap isnt anything we havent seen, nor a 10.8, even from cars that heavy.

Water/Methanol Injection CAN increase power if TUNED for it on a Dyno. I have personally seen over 10 cars with kits LOSE power, and in particular mid range torque with Water/Meth Injection kits before being tuned properly. John's car has not been tuned on a dyno for his kit yet, which is why it is probably hurting his mid range and top end at the moment. With tuning he will no doubt go 133mph+ and probably get down to a 10.5 or so.
Im 100% sure that the car isnt loosing power because of the kit, they would have removed it otherwise.

^The kit itself from HKS consists of:
- HKS aluminium hard pipe kit for R35 GT-R
- HKS silicon hose joiners
- HKS wastegate actuators for standard R35 GT-R turbos
- HKS Electronic Valve Controller (EVC) boost controller
- HKS dump and front pipes (delete all catalytic converters)

I would guess that the 1/4 issue is that it gives an idea as to the power a car puts out. That is the only reason I reference it. But I agree that if we wanted drag cars we could just buy an old plymouth aspen or dart, stuff a big block crate motor and stick a supercharger on it and bam 9-10 second et's all day long.
