Have a look at the customer list (Honda, Renault, Toyota, and Ferrari F1 departments use VBOX), you will even see RR listed there !
Testing method & equipment: NO HYPE! (sample customer tests at bottom of this page)
Rice Racing developed analysis is unrivaled at the price point (or any price point for that matter!) and goes back to first principles of elementary vehicular dynamics & mechanical engineering (< there is no fudge factors here, CLICK on links to see so formula development **ALL Rice Racing numbers match REALITY***).
Each car is checked for basic mass with our Tanner high precision wireless corner scale system, then a series of tests are done on your specific vehicle to determine the actual Cd (drag coefficient) and f (tire rolling resistance coefficient) via the ultra high accuracy Race Logic VBOX3i and IMU data. From there RR developed formula are used to determine the exact driving power or wheel power your car has in reality, in real time, as you drive it! There is no other more factual/relevant testing that can be applied. Anyone can go test in an artificial environment and give you a guess of what the car (via artificial environment testing) has, but very few people have the equipment or the expertise to give you a comprehensive "actual" vehicular analysis as Rice Racing can.
I measure handling dynamics of vehicles as well (acceleration in X,Y,Z axis along with Vehicle PITCH, ROLL and YAW) for those who want to quantify handling traits or fundamentals of weight transfer etc, other variables such as ACTUAL wheel slip percentage to determine drive efficiency and grip levels are all recorded *for applicable vehicles* < Great for mapping of variable boost controllers or traction control units or even checking function of differentials effect on acceleration. The same can be applied to braking efficiency (distribution or ABS function).You can be assured when you come to me your car will be fully analyzed and professionally tweaked to it's maximum potential.
Here is a link to some testing analysis, a customer will get a basic report of the following *CLICK to view report*
*power report with AFR logged, boost pressure, TPS, acceleration rate, rpm, to name but a few select parameters.
*90kph to 140kph analysis of 3rd gear test performance (which can be used as a guide for all future upgrades or comparisons to others)
Other testing options are available on request and for a small nominal fee, custom tests or analysis can be carried out.
1/4 mile or circuit track racing analysis to name but 2 popular applications (gearing optimization & even identifying driving faults)
Example real power analysis & boost response:
VERY IMPORTANT INFORMATION ON variability of INACCURATE Drag Racing Time slips !
Should the owner of one of these world class meters want to compare its performance against the shit backwards ghetto equipment used at drag strips, he or she will need to
deal with "rollout," which is the distance a vehicle can move before
triggering the archaic backwards timing light system.
A little drag-strip primer: As a
car creeps toward the two light beams of the starting area, its front
tire will eventually block the first beam and trigger a "prestage"
warning. This informs the driver that the official starting line, where
the "stage beam" shines across the track, is only seven inches ahead.
When the front tire triggers that second beam, the vehicle is properly
staged for a run. However, the vehicle's position can still vary by
well over a foot while its front tires are blocking the stage beam.
This is critical, because the drag-strip clock does not start until the
second light, or stage beam, is uncovered. It is this distance that is
the critical rollout.
The length of the rollout depends on the
diameter of the tire and where the driver chooses to position the car
at the start. Although the rollout distance is typically only a foot or
so of a quarter-mile, it can affect the elapsed time by as much as 0.3
second, and to the serious gearhead, that's an eternity. Therefore, we
needed to make sure every run in our test started at precisely the same
point because of that 0.3-second issue.
Also, a car accelerates to
3 mph in about 12 inches!
ET = (weight/hp)^0.2574 x 7.3571 & mph = (hp/weight)^0.3018 x 215.39 & hp = weight/(ET / 7.3571)^3.8850
are great formula to use for street cars, you can work out to very
close actual engine power if you know the weight of your car (pounds)
as run. http://www.stealth316.com/2-calc-hp-et-mph.htm and you will see a raft of road cars tested to confirm LRT formula here http://www.stealth316.com/misc/performance_lrt2.xls NOTE: Weight must be TOTAL RUN WEIGHT, not estimated but rather measured.

^ great article
showing back to back of 3 different tunes, correlates
very well with all the types of cars I have tuned and have my own
certified V-BOX data on....... you can compare from Matt's stock std
Spirit R Type A through to ONE58 (Rob's) maximum effort BPU car (comes
very close to stripped out race RX7!) in all area's. 60mph 1/4 time
and mph (though PFS race car is about 150kg lighter! and uses slicks).
