SECTION 3 - TOURING CAR
SECTION 3.2 - PERFORMANCE TOURING
A. PURPOSE
Performance Touring (PT) is intended to provide the membership with the opportunity to compete with
a high degree of both safety and convenience. PT along with its sister series, Super Touring and Super
Unlimited provide a home for nearly every type of racecar to compete in a fair and logical competition
environment.
B. STUCTURE
Cars progress from a Base Classification (outlined in the NASA Performance Touring rules Section 5.2
starting on page 7) or an assigned WCMA Base Classification (See SECTION 3.2 -D). Final competition class
determined by the Base Classification plus (or minus) any modification points assessed (see NASA
Performance Touring rules Section 5.3 starting on page 18). Each competition class has a minimum
adjusted WT/HP ratio to help ensure fair competition, these ratios are only considered once a vehicle has
a competition class. As vehicles potential performance increases they move upwards from PTF to PTB to
ST to SU. Any vehicle adjusted WT/HP of less the 10.5lb/hp competes in ST or SU and should refer to
section 3.2

Re-class e-mail in order to prevent disqualification.
If the vehicle is modified, and the power level or weight has changed, a new request for a WCMA
Base class must be sent to the WCMA.
Any vehicle that has been assigned a base class by the WCMA and has had a change to either its base
class or its base weight in the table in NASA PT Section 5.2.2 since the WCMA base class was
approved, MUST be re-submitted for re-classification
The competitor must include a copy of the Official WCMA base class e-mail, along with the Certified
Dyno report when submitting the PT Car Classification Form to the Regional Tech inspector or Race
Director before competition.
All competitors will be required to include the latest Certified Dynamometer (Dyno) report and
minimum weight in their vehicle logbook at all times.
Any subsequent modifications or adjustments done to the car that could alter power output will
require repeat Dyno testing, and a new Certified Dyno report.

SECTION 3.2 - PERFORMANCE TOURING
E. WCMA DYNO TESTING PROCEDURES
1. Dyno Testing
The following procedures apply to all vehicles being tested on a dynamometer, whether for initial classing
purposes, or for technical inspection post-competition.
2. Dyno Testing Procedures
a. A certified Dyno report consists of
i.
Three separate, reproducible Dyno tests for each Fuel/Timing Map or boost controller setting
with SAE J1349 Rev JUN 90 SAE correction
ii.
the car owner’s name
iii.
car number
iv. car year/make/model
v.
shop name and phone number
vi. Dyno operator’s name on the Dyno sheet
vii. Is accompanied by a completed ST/PT Dyno Certification Form.
b. All Dyno tests must show
i.
horsepower and torque on the Y-axis (vertical)
ii.
Engine RPM on the X-axis (horizontal) of the Dyno graph.
iii. The numerical table of horsepower and RPM (in 50 RPM increments) must be included in the
report (for all Dyno tests completed after December 1, 2015).
iv. An inductive pickup or other direct sensor shall be used to measure engine RPM (as opposed to
obtaining RPM data from the ECU/OBD port or from calibration from the vehicle’s
tachometer.)
1.
If this is not possible due to vehicle configuration, the Dyno operator must note on the
Dyno sheet the method used for obtaining RPM data, and the reason for not using an
inductive pickup or sensor*.
c. Dyno testing shall be done with
i.
the vehicle at normal operating temperature
ii.
at least 28 psi tire pressure (but should be at normal operating tire pressure if higher),
iii. In the gear producing the highest horsepower readings.
1.
It is the competitor’s responsibility to ensure that the vehicle is compliant with
horsepower limits in ALL gears.
iv. The vehicle’s hood shall be open with a cooling fan placed in front of the engine during testing.
v.
Engine, ECU, boost controller, etc. settings shall only be altered between Dyno runs in order to
obtain the required additional sets of three Dyno tests for each of the alternate ECU
Fuel/Timing maps and/or boost controller settings.
vi. The highest peak horsepower number of the three tests will be used as the official certified
horsepower for weight to horsepower calculations. (with the exception of the ST3)
vii. A smoothing factor up to five (5) shall be used.
viii. All Dyno graphs must show decreasing power for 1500 rpm from the peak horsepower level, or
the car must reach the rev-limiter during the Dyno testing.
ix. All horsepower measurements will be rounded to the nearest whole number.
x.
Test results using a Mustang or Dyno Dynamics dynamometer will have 10% added to the
maximum horsepower reading
1.
To obtain the number that will be used to calculate the “Adjusted” Weight/Power Ratio
(Mustang or Dyno Dynamics Dyno whp x 1.1 = Maximum whp for wt/hp calculation).

SECTION 3.2 - PERFORMANCE TOURING
3. Dyno Compliance Inspections
a. Dynamometer tests are official and certified when performed by series Officials for compliance
testing (without the need for a Dyno Certification Form—but must be signed by the Official).
b. It is the responsibility of the competitor to be within power levels on any device that a WCMA official
chooses to use for testing.
c. For compliance testing, the Official and the dynamometer operator will determine
i.
Which gear(s) to use
ii.
How many test runs to perform for any given vehicle
iii. What the normal operating temperature is for that vehicle.
iv. Tire pressures shall not be adjusted between the time the vehicle was on track competing and
the time of Dyno testing.
1.
If the competitor violates this rule, the tires will be inflated to 40 psi before compliance
Dyno testing.
d. Prior to the dynamometer inspection the competitor may top off any fluids needed to ensure the
engine and drivetrain are not damaged during testing.
i.
The fluids must be added with a WCMA Official present.
ii.
No other modifications or adjustments may be made to the car.
e. To ensure fairness, an Official, or an individual appointed by an Official, may operate any cars being
inspected.
f. At their discretion Officials may have the vehicle sealed and transported for off-site Dyno testing at a
later date
g. Vehicles may not have any adjustments during the competition day to systems that allow adjustment
of horsepower levels that would serve to alter Dyno, Examples of such systems are
i.
driver-adjustable electronic tuning
ii.
engine timing advance devices
iii. fuel pump output modification devices
iv. boost controllers
v.
adjustable MAP and MAF voltage clamps,
h. Any restriction device placed in the air intake system must be clearly identified as such and marked
to indicate its dimensions.
i. Vehicles that have more than one fuel/timing program or “map” in the computer/ECU/PCM must
submit a certified Dyno report (3 pulls) for each of those fuel/timing “maps” which will be used
during competition.
i.
The method used to switch between these “maps” must be clearly written on the PT Car
Classification Form.
j. Any hardware that allows a competitor or crew member to wirelessly or directly connect to the ECU
(or alter ECU maps) at any time during competition or post-competition impound is strictly
prohibited
i.
Regardless of whether such hardware is external or internal to the ECU, and regardless of the
direction of data flow.

SECTION 3.2 - PERFORMANCE TOURING
F. FORMS, INSPECTION, PROTESTS
1. Car Classification Forms
a. All competitors will submit a completed Performance Touring Car Classification Form (3.2.C) to the
WCMA prior to the first qualifying session of a race day.
i.
A copy of the current completed Performance Touring Car Classification Form will be kept with
the vehicle logbook.
b. Any competitor that has not submitted a Car Classification Form may be disqualified or moved to the
Super Unlimited race class.
c. Once a form has been submitted during a season, if there are no modifications to the vehicle, a new
form does not need to be submitted at subsequent races.
i.
However, if there are any changes to the vehicle that would alter the modification points for
that vehicle in any way, either a new form needs to be submitted, or the WCMA may allow the
driver to revise the old form (again, prior to any qualifying sessions that the vehicle is run in
with the new modifications).
ii.
Failure to comply with the correct procedure regarding Classification Forms is a violation of the
rules that may be penalized, regardless of whether or not the vehicle’s competition class has
changed.
d. The Car Classification Form substitutes for the class rules and vehicle specification sheet that would
be present under a traditional racing paradigm.
i.
As such, the Form needs to be kept up to date, and accurate at all times.
e. Forms can be downloaded here: http://www.wcma.ca/new/racing/racing-forms/
f. A driver may choose to compete at any time in a higher level PT class than would be dictated by the
Performance Touring Car Classification system.
g. A car may be modified an unlimited number of times
h. Substitute vehicles may be used provided they comply with all PT rules.
i.
Substitution of a vehicle or class change after the qualifying session is completed will result in
the new vehicle/re-classed vehicle being placed at the back of its class in pre-grid.
2. Vehicle Inspection
a. All completed PT Car Classification Forms will be available from the WCMA for review by any
competing driver by request while at the track.
b. Performance Touring vehicles are subject to detailed inspection by any WCMA Technical Inspector
and visual inspection by Performance Touring competitors at any time when the car is at the track.
c. WCMA Officials retain the right to request any disassembly or other procedure required to verify
vehicle compliance.
d. At random times or at the discretion of WCMA Officials, any car may be ordered to report for rules
compliance on a chassis dynamometer.

D. DYNAMOMETER/POWER TESTING
1. Dyno Testing
The following procedures apply to all vehicles being tested on a dynamometer, whether for initial classing
purposes, or for technical inspection post-competition.
2. Dyno Testing Procedures
a. A certified Dyno report consists of
i.
Three separate, reproducible Dyno tests for each Fuel/Timing Map or boost controller setting
with SAE J1349 Rev JUN 90 SAE correction
ii.
the car owner’s name
iii.
car number
iv. car year/make/model
v.
shop name and phone number
vi. Dyno operator’s name on the Dyno sheet
vii. Is accompanied by a completed ST/PT Dyno Certification Form.
b. All Dyno tests must show
i.
horsepower and torque on the Y-axis (vertical)
ii.
Engine RPM on the X-axis (horizontal) of the Dyno graph.
iii. The numerical table of horsepower and RPM (in 50 RPM increments) must be included in the
report (for all Dyno tests completed after December 1, 2015).
iv. An inductive pickup or other direct sensor shall be used to measure engine RPM (as opposed to
obtaining RPM data from the ECU/OBD port or from calibration from the vehicle’s
tachometer.)
1.
If this is not possible due to vehicle configuration, the Dyno operator must note on the
Dyno sheet the method used for obtaining RPM data, and the reason for not using an
inductive pickup or sensor*.
c. Dyno testing shall be done with
i.
the vehicle at normal operating temperature
ii.
at least 28 psi tire pressure (but should be at normal operating tire pressure if higher),
iii. In the gear producing the highest horsepower readings.
1.
It is the competitor’s responsibility to ensure that the vehicle is compliant with
horsepower limits in ALL gears.
iv. The vehicle’s hood shall be open with a cooling fan placed in front of the engine during testing.
v.
Engine, ECU, boost controller, etc. settings shall only be altered between Dyno runs in order to
obtain the required additional sets of three Dyno tests for each of the alternate ECU
Fuel/Timing maps and/or boost controller settings.
vi. The highest peak horsepower number of the three tests will be used as the official certified
horsepower for weight to horsepower calculations. (with the exception of the ST3)
vii. A smoothing factor up to five (5) shall be used.
viii. All Dyno graphs must show decreasing power for 1500 rpm from the peak horsepower level, or
the car must reach the rev-limiter during the Dyno testing.
ix. All horsepower measurements will be rounded to the nearest whole number.
x.
Test results using a Mustang or Dyno Dynamics dynamometer will have 10% added to the
maximum horsepower reading
1.
To obtain the number that will be used to calculate the “Adjusted” Weight/Power Ratio
(Mustang or Dyno Dynamics Dyno whp x 1.1 = Maximum whp for wt/hp calculation).

3. ST3 Average Horsepower
It is anticipated that in ’17, this formula will be adopted for all TT/PT/ST classes
a. The horsepower used for calculating the Adjusted Wt/HP Ratio for the ST3 class will not be the
maximum horsepower of the three Dyno runs, it will be a calculated average giving a better
approximation of the maximum horsepower available over a range of usable RPM.
i.
For pre-competition testing, the Dyno test with the highest maximum horsepower will be used
to calculate this average (not an average of the three Dyno runs) as follows
ii.
all horsepower numbers will be rounded to the nearest whole number before any calculations
b. Calculation
iii. Definitions
1.
Avg HP = Average HP calculated and used in in the Adjusted Wt/HP Ratio
2.
Max HP = Maximum horsepower shown on the actual Dyno graph
iv. Data Points
1.
The following ten (10) data points will be obtained from the Dyno’s 50 RPM data export
numeric RPM/HP table printout
a.
Horsepower at: 500 rpm, 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm greater than
Max HP rpm
b.
Horsepower at: 500 rpm, 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm less than Max
HP rpm
c.
If any of the above data points at higher RPM than Max HP RPM do not exist due to
redline, then those potential data points will not be used in the calculation of Avg
HP
v.
Formula for Avg HP
vi. Avg HP = (Max HP + (sum of the three highest data points))/4
4. Dyno Compliance Inspections
a. Dynamometer tests are official and certified when performed by series Officials for compliance
testing (without the need for a Dyno Certification Form—but must be signed by the Official).
b. It is the responsibility of the competitor to be within power levels on any device that a WCMA official
chooses to use for testing.
c. For compliance testing, the Official and the dynamometer operator will determine
i.
Which gear(s) to use
ii.
How many test runs to perform for any given vehicle
iii. What the normal operating temperature is for that vehicle.
iv. Tire pressures shall not be adjusted between the time the vehicle was on track competing and
the time of Dyno testing.
1.
If the competitor violates this rule, the tires will be inflated to 40 psi before compliance
Dyno testing.
d. Prior to the dynamometer inspection the competitor may top off any fluids needed to ensure the
engine and drivetrain are not damaged during testing.
i.
The fluids must be added with a WCMA Official present.
ii.
No other modifications or adjustments may be made to the car.
e. To ensure fairness, an Official, or an individual appointed by an Official, may operate any cars being
inspected.
