Ferrari 250 TR - Modifications.

The engine oil sump has been lowered by one inch by using a bespoke alloy spacer.

The engine oil pick-up pipe and filter rose has been lowered to suit.

The FULL mark on engine oil dipstick has been altered to suit.

A small spring has been used to prevent the possibility of the dipstick from vibrating loose.

Four hinged flaps (similar to Ferrari 330) have been added to the sump pan.

A 1.5L Moroso Oil Accumulator has been fitted - in cockpit.

An oil cooler has been added.

 

The four straight ended exhaust pipes have been replaced with four megaphone type tail pipes.

The gear change leather gaiter has been changed to a Ferrari style “gate” with a reverse lock-out.

An electric cooling fan over ride switch has been added to the dash.

A restrictor is in the top hose (near the radiator) of the water system.

The system is over cooled and runs blanking on the radiator.

The high capacity bespoke radiator is of aluminium construction.

There are two cooling fan switches fitted to the radiator, one at the top and one at the bottom giving an option in operation.

 

A thicker (24mm) bespoke front anti-roll bar (ARB) with solid alloy blocks has been fitted. Hard bushes are fitted to the ARB drop links.

 

The rear dampers are Koni and now have adjustable platforms.

There is a grill removal / replacement tool, a wire hook, which is taped to the chassis near the fire extinguisher.


There is a bung in each choke (12) of the carburettors to prevent the ingress of foreign objects, it is important to remove prior to the engine turning over. Replace when finished.

 

The original GTE rear axle has a bespoke limited slip differential, by DR Engineering Coventry.

The differential parallel bearings have been replaced with the later taper type.

A brake bias knob with lock, marked F & R has been added to the right hand side of the dash, near the ignition keyhole.


For an improved rear view an oblong central mirror replaces the round style.

A side mirror has been added to each end of the windscreen to improve the rearward

view.

 

The Michelin Pilote 16”x600 race tyres are road legal and are fitted with tubes with bolt in valves suitable for racing.

Brake pads are Ferodo FRP201C CP2340 D46 front and rear.

Brake fluid is AP 600.

Crossland oil filters are 532 Main and 541 By-pass.

The fuel filter is Crossland 522.

The engine oil is 20/50 Valvoline VR1 Racing.

The Differential oil is Torco SGO 75w90 with a Torco LSD additive.

The coolant is 90% GM Longlife antifreeze. The water system is of 11Lt capacity.

The front suspension spring cups are on the lower groove.

Brake bias is set to 60F/40R which is 7.5 turns from the front.

The tachometer is inclined for ease of reading at speed on track.

Filler and drain plugs are lock-wired as required.

Fuel filter and differential oil have been replaced at 5659 miles on November 24th 2011.

Engine oil and (two) engine oil filters, brake fluid replaced at 6141 miles on December 2012.

The gearbox oil has not been changed but the level has been checked and is correct.

Corner weights are set for a 100kg driver.

Mileage as of June 1st 2013 is 6179.

 

When I purchased the car in 1997 the mileage on the clock was 450.

 

The first time I raced the TR I kept the original seat, realising it was not Ideal, I chose to remove the very comfortable seat back and squab and replaced it with a "racing" sit in a bag of foam type. This gave me much more room and brought my seating position much lower in the cockpit and was also a snug fit. 

 

Modifications required for racing:

A battery master switch also incorporating a low voltage switch and an alternator discharge resistor has been added.

Two one liter engine breather catch tanks have been fitted.

A battery master “Pull Off” red T knob has been added to the left of the water temperature gauge.

Three Pirelli Ferrari Formula Classic (PFfC) roundels are on the car, one on each door and one on the nose.

A “Pull for Off” label is adjacent to the ignition key.

A bad weather light switch has been added to the dash.

An “E” (for extinguisher) has been placed on the passenger door.

A hand held fire extinguisher is fitted in the sill below the passenger door.

There are four yellow towing eyes, one on each corner of the suspension each marked by a yellow arrow.
