A Bora and Silvia on Broquet - WheelsAsia

VW Bora 1.6(A)

A Volkswagen Bora 1.6(A) was fitted with the in-line unit B30, suitable for cars with engine capacity of up to 1.6 litres. Fuel consumption was monitored over a period of two months from March to April. During that time, the car traveled a total distance of 2,567kms with approximately 40 per cent city driving and the rest on expressways.

The average fuel consumption during the start of the test was 10 litres per 100kms and by the end of March, this figure had dropped to 9.6 litres per 100kms. By the end of April, the average fuel consumption figure was about 9.1 litres per 100kms. In addition to better fuel economy, the engine felt more powerful, especially when being driven hard and even it was extended to its redline, it remained smooth.

This is a product worth using and backed by a 30-day money back guarantee given by the sole distributors of Broquet, Universal Consultants, what have you got to lose.

Nissan 200 SX (S14)

To test what effects Broquet has on performance, a 1997, mildly modified Nissan 200SX was used. This car has a 2-litre turbo-charged engine running on 1.0 bar of boost. The SR20DET engine is well known to be able to accept modifications. For turbo-charged cars, basic tuning parameters will always centre on fuelling, ignition timing, and boost level. The common limit to determine how aggressive tuning can be is the point of detonation (or pinging). Broquet is known to reduce detonation, and thus extend the limits of tuning.

The car was warmed up to operating temperature with a 15-minute drive. A base line run was then taken to record horsepower and torque figures. As this car has been tuned only to 6500rpm, a rev limit of 6800rpm was set, and the car produced a peak of 252 bhp and 304 Nm of torque.

Then, 3 sachets of Broquet B/8T In-Tank Systems was added into the fuel tank and the car driven for another 30 minutes to allow the fuel to interact with the catalyst. The car was then put on the dynamometer again, and after making sure that testing conditions were similar to the base run, engine power was measured again.

Results were impressive as the car actually gained 6.4 bhp, and more importantly, 9.3 Nm more torque. Power gains were more evident after 4000rpm, showing that the catalyst fuel actually benefits the engine when the turbo boost comes on. Both tuner and owner of the car walked away from this test happy, as they are now assured that the engine is running near optimized combustion levels after the Broquet treatment.
