Introduced in
1964, the BMW 1800 Ti/SA was a
refined road car as well as a serious
racer with many victories, including the Spa 24 Hours race. Only
200 models were built and only 25 were exported to the USA.

Information
|
The
BMW 1800 Ti/SA was the high-performance version of the
BMW 1800
Ti, offered to a limited clientele. The BMW 1800 Ti/SA was
produced to satisfy demand for a top performance car that could
also be used every day on the road.
TISA on the Track
The standard
engine for
the BMW 1800 Ti/SA was the BMW 1800 Ti 4-cylinder engine. With a
reworked head, new camshaft, dual side draft Weber 45 DCOE
carburetors and an increased compression ratio of 9.5:1 the BMW
1800 Ti/SA produced 130 DIN (150 SAE) horsepower. As an option,
you could also get a "tuned" version from BMW with a compression
ratio of 10.5:1 and producing 150 DIN (180 SAE) horsepower!
Dual side draft Weber 45 DCOE carburetors
The Ti/SA
had a top speed of 125 mph and a 0-60 time of 9.4 seconds.
Sold mostly
to racers, for homologation only 200 models were built, from
February to June of 1965. Look for VIN numbers from 995000 to
995200. More...

Design
|
While the main
difference between the
1800 Ti and the 1800 Ti/SA was the engine, BMW made other
improvements to handle the extra performance of the Ti/SA.
The
Ti/SA featured an all-synchronized five-speed gearbox. The gear
ratios were excellent with first going to 31 mph, second to 60,
third to 80, fourth to 100 and fifth to the top speed of 125 mph.
The Getrag five-speed gearbox was the first on a postwar BMW.
BMW
used special racing brake pads on the 10.5 inch front disc brakes.
Some models had 4-wheel disc brakes, while other models had rear
drum brakes. German Dunlop S.P. tires were available in either 550
x 14 or 600 x 14 sizes. Unlike the BMW 1800 Ti, there were no bumpers or wheel covers on
the Ti/SA. Weighing in at 2320 lbs., the Ti/SA had an impressive
weight to horsepower ratio of 15.5, especially when compared to
the 30.4 ratio of the 1500.
The
interior of the BMW 1800 TI/SA
In the
interior, from supplier Raystall BMW provided an oversized bucket
seat for the driver with ample side protection. As one reviewer
noted, "the high sides give excellent support for the rapid
cornering that the BMW does so easily." For better vision, the
tachometer was a separate unit and it extended out from the
dashboard towards the driver. A sporty, wooden steering wheel was
supplied on many TISA's.

Korman has competed in BMW sedan racing since his purchase in 1964
of one of the first BMW 1800 Ti sedans sold in the United States.
In
his first professional racing he won two national championships in
Southeast Asia, first in his 1800 TISA, then in an FIA Group 5 2002
prepared by Yontrakit Motors in Bangkok.
"My
first BMW, a 1964 1800 TISA four door sedan regularly beat the
performance sport cars of its day in autocrosses: E-Jaguars, Lotus
Elans, Corvettes, MG Twin Cams, Porsche Super 90's, and more than a
few 911's! Along with very minor engine changes, a good suspension
package, wider wheels and tires, and a close ratio gearbox, my most
effective "speed secret" was the change to a 4.75 gear set!"
