I. DEFINITION
TOP
A Formula FB/F2 is a single seat, open-wheel racing car with firewall, floor, and safety equipment, that was built between January 1,1966 and before January 1,1970, conforming to S.C.C.A./FIA regulations of that period and to the current Monoposto Racing Regulations.

II. GENERAL
TOP

a. Wheelbase: Free
b. Track width: Free
c. Maximum body width: 110 cm.130 cm between the wheels including lateral fuel tanks.
d. Maximum body height: 90 cm not including safety roll bar or engine airbox.
e. Minimum weight: 930 Ibs. Measured as qualified or raced, less driver.
f. Body panel modifications restricted to replacement panels of alternative materials. Magnesium, Titanium, and composites prohibited.
g. Chassis must remain as originally designed, but with local stiffening permitted.
h. Suspension may not be adjustable unless originally manufactured in that form.
i. All heim type joints must be captured or have captive washers.
j. Aerodynamic devices of any type are not permitted. (i.e., wings, canards, sidepods, sports car nose, etc.)
k. Brakes must be original as specified by the constructor for that model, or an acceptable equivalent. Brakes must be in perfect working order.
l. Cars must have an onboard electric starter.
m. Wheels should be of original type and size. Minimum wheel diameter 13 inches. Maximum wheel width: Front - 10 inches, Rear - 12 inches.
n. Treaded tires manufactured for racing purposes only will be allowed. (see F2/FB tire regulations)

III. TRANSMISSION
TOP

a. No more than five forward speeds.
b. An operational reverse gear is required.
c. Differential type is free.
d. Power may only be applied to the two rear wheels.

IV. ENGINE
TOP

a. Displacement: Over 1100cc's and up to 1600cc's inclusive.
b. Superchargers, turbochargers, and nitrous oxide systems not permitted.
c. Engines shall be derived from automobiles recognized by the F.l.A. in Group 1, Group 2, or Group 3, from January 1,1966 to December 31, 1970. The following engines are eligible: Lotus Ford 1600 Twin-Cam, Alfa-Romeo 1600 Twin-Cam (incl. GTA), Porsche Pushrod 1582, Datsun 1600 SOHC, BMW 1600 SOHC, Ford 1500 Pushrod, Ford 1600 Pushrod, Fiat 124 DOHC 1438, Renault Gordini 1600, Toyota 1600 Pushrod, Fiat 1592 DOHC. Other engines from this period may be submitted for approval.

THE FOLLOWING MODIFICATIONS ARE PERMITTED
d. The use of any carburetor (s) and intake manifold (s).
e. The use of any exhaust manifold (s).
f. The use of any oil sump.
g. The use of any oil pump (s).
h. The use of a dry sump lubrication system.
i. The use of any crankshaft with the stroke specified in the homologation forms for the engine.
The stroke of the crankshaft cannot be shortened or lengthened from this specified stroke.
j. Main bearing caps may be reinforced or substituted.
k. The make and location of the ignition coil and condenser may be changed.
l. Any distributor and/or transistor ignition may be used provided its installation does not require any modification of the engine. The ignition triggering mechanism must be contained in the distributor.
m. Any make or type of sparkplug may be used.
n. Substitution of the clutch and flywheel is allowed provided there is no increase in clutch diameter.
The use of dowel pins is permitted.
o. Any pistons and piston pins may be used.
p. Any camshaft (s) may be used.
q. Cam followers may be altered or substituted.
r. It is permitted to lighten, balance or modify in shape by tooling, the standard or optional components of the engine, provided it is always possible to identify them positively as such. It is not permitted to add material to these components unless specifically authorized.
s. Engines may be rebored a maximum of 1.2 mm (.047 inches) over the standard size provided the resulting increase in total displacement does not exceed 1 600cc's.
t. The use of any alternate engine components considered replacement parts such as seals, bearings, valve guides, nuts, bolts, studs, washers, and gaskets are allowed provided they are of the same type and dimension. Bushings may be added where none are fitted as standard provided that they are concentric and that the centerline of the bushed part is not changed.
u. Water and oil passages may be restricted or plugged.
v. The substitution of valve springs, valve spring retainers, and keepers is permitted. Any pushrods may be used.
w. Pulleys may be altered or replaced with others of unrestricted origin. The use of any crankshaft vibration dampener is permitted.
x. The compression ratio may be increased by machining, using any head casket (s) or eliminating of head gasket (s).
y. The installation of any vent or breather is permitted.
z. The generator or alternator is free, and optional.
aa. The use of any rocker arms or rocker arm supports.
bb. Use of any connecting rod of the same basic material.
cc. Valves are free in both size and material, provided the valve centerline is not altered. Four valve heads are not permitted on FB cars. Genuine F2 cars may use four valve heads if the car in question used them during the pre-1970 period.
dd. The use of any fuel pump (s) is permitted.
ee. Valve or cam covers may be substituted, provided the replacement cover affords no additional function than that of the original stock cover.
ff. Any external surface of the engine may be plated, painted, or anodized.
gg. Engines produced with a cam carrier as a separate and distinct piece from the cylinder head or engine block may replace that cam carrier with a cam carrier of other manufacture, provided the replacement cam carrier affords no additional function other than the original cam carrier and provided the type and number of camshaft bearings remains the same.
hh. The replacement of any jack shaft or idler shaft with another of the same basic material as the standard shaft is permitted, provided it performs no additional function over the original shaft.

THE FOLLOWING MODIFICATION IS NOT PERMITTED
ii. To change the type or make of engine originally fitted. (Except as specifically authorized by Monoposto Racing.) Furthermore, placing F2 derived engines in FB cars renders the car ineligible for Monoposto Racing events.

MODIFICATIONS:
jj. It is permitted to strengthen the chassis as required to support roll bars, seat belt anchors, fire extinguishers, fuel cells, or any other safety equipment added to the car.

V. REGISTRATION
TOP

a. The scrutineering committee reserves the right to exclude any car from registration for any reason.
b. Drivers must be members of MONOPOSTO RACING. The drivers committee reserves the right to review driver qualifications as required.

V. ADDITIONAL ELIGIBILITY

a. Cars built up to December 31, 1965 may be eligible to participate in the Class B at the discretion of Monoposto Racing, provided they adhere to all regulations.
b. Cars built between January 1, 1970 and December 31,1972 may be eligible to participate at the discretion of the Monoposto Register, provided they adhere to all regulations.

c. Any member requesting a car built between January 1, 1970 and December 31, 1972 must do so in writing to the Monoposto Racing Class FB/F2 representative.
