Honda turned the motorsports world on its ear when it introduced its VTEC engine technology. With specific outputs in the 100 hp per liter range, it rivaled the output of even forced-induction engines of the time.
This Integra combines a K-series engine (the original Integra Type R motor is a B18) with a Garrett turbo running a 72 mm inducer. This is a class limitation, with minimum vehicle weights of 2500 lbs. Needless to say, all the internals of the K-series motor used top-shelf parts to withstand the boost. Very little information on the engine can be found but with an 8.9 best, a 166 mph trap speed, and assuming a weight of 2600 lbs., engine output can be calculated to be over 1,000 horsepower.
But the tuning of this car was not limited to the engine. You can make a ton of power but it has to be usable. The owner, Tony Palo, says, “The most overlooked things I see are good engine management systems, good boost controllers, and suspension. There are a lot of cars out there that make the power on the dyno, but only a small portion of them that run what the dyno numbers say they should.”
When the team is at the track, Palo always looks at the data from the logger after a run and goes over the time slip. After looking at the plugs, the datalog, and the time slip, the team makes whatever changes they feel will make the car go quicker. The goal is to go faster every time the car goes down the strip.
