Fastest 12a on the Earth?
Submitted by SuperUser on Thursday, August 1, 2002 - 12:00am

Boris Rojas is the owner and driver of the Delirium Racing Team. Recently, their 1972 Datsun 1200 with a turboed 12a ran a 8.27 at 160 at the Salinas Speedway. It is a family and friend effort to complete this project. Boris currently owns a car repair shop in Guaynabo, Puerto Rico called Cars Motorsports.

The team is located in San Juan, Puerto Rico, and other team members include Ismael Velazquez, the pitman, Jose Burgos, the engine builder, and Jorge "Oso" Juarbe the Haltech fuel injection system programmer.

The car is a full tube mild steel chassis, the body is complete fiber glass of a 1972 Datsun 1200, the weight of the car is 1850 pounds with the driver, it of course has the 12A engine with only a port job, with an Innovative turbo and wastegate adjusted at 27 pounds of boost, a Tial blow off valve, it has 4 1100cc inyectors on a custom built throttle housing, stock distribuitor, with MSD boxes and coils a Greddy intercooler.

The fuel used is VP racing fuel suppiled by an Aeromotive fuel pump and regulator. They use a Mc Leod double disc clutch and a G-Force 5 speed clutchless tranny. This hooks up to a 9" ford rear end with 4.56 gears and 29X12 Goodyear slicks mounted on Aluma star 12 inch rims. Like I said the fuel injection system is a Haltech F-9.

The fist time out they went to the Carribean Raceway Park and with traction problems ran 8.51 at 159 mph. The second time, the team took the car to Salinas Speedway and ran 8.27 at 160 mph, with only 1.23 on the 60 foot mark. After a chassis adjustment they should be near 1.16 on the 60 foot mark, making the car run low 8.20's or high 8.10's.

Boris has been involved in drag racing for around 10 years, starting out runing a Mustang doing 12 seconds, then after that he went into the smaller cars like a 1972 Datsun 1200 with a 1.8l Toyota engine and nitrous . This made the 1/4 mile in 10.7 seconds. Then he obtained the Datsun Delirium as an unfinished project. He installed the same 1.8l Toyota engine, and ran a 9.6 second 1/4 mile. He then decided to put a rotary engine in the Delirium. He was at first going to put a 13b with nitrous setup in, but then decided to do something different. Thus, the project has was given the 12a
