If things like variable valve timing and dual overhead cam engines bore you then chances are you've heard of Bisi Ezerioha. A Nigerian-native and tuning facility Bisimoto Engineering's founder, Bisi, thrives on non-VTEC, SOHC Honda engines. And why shouldn't he? The guy's coaxed more power out of the '90-'93 Accord's F-series engine than what others have from more hip-and-modern, big-and-burly K powerplants. Uni-cam power figures in excess of the 450hp mark are the norm for Bisi. Oh, did we mention he accomplishes all of this under the guise of naturally aspirated motivation?
Numbers like these are no accident for the '03 IDRC All-Motor drag racing champion though. A methodical, scientific approach is the key to Bisi's success-things you'd expect from a trained chemical engineer, a former pharmaceutical research technician, and a guy with a PhD in the works. Yeah, a PhD; we're talking about someone who used to mix his own race gas that, when burned, gave off a variety of fruity scents. Heck, we're talking about a guy who owns his own lab coat, has the periodic table memorized, and actually uses things like mercury and manometers on a day-to-day basis. Walk around SoCal-based Bisimoto Engineering and, along with the Dynapack dynamometer that Bisi uses to tune everything from AEM-equipped NSXs to carbureted D15s, you're likely to stumble across more than a few things that look like they belong in a laboratory, not a dyno shop. What the heck is that mortar and pestle doing on the toolbox?
Bisi's claims to fame are many. He was the first to implement the now-famous transmission adapter plate to a Honda, drove the quickest and fastest carbureted front-wheel-drive car in history, and rocked the fastest street-driven, all-motor D-series of its time clocking in with mid-12s at 107 mph. Bisi's also one of the few to bust the 9-second barrier wide open without the help of forced induction. He got close to it in his carbureted, D-series-motivated CRX during the early part of the decade prior to building Stitch, his F-series-powered, all-aluminum chassis Honda Insight-a car that runs 9s with ease and is continually contested by its competitors, although not once penalized. The Insight serves as a test bed for a majority of Bisimoto products, so customers are assured there's science behind every purchase. Bisimoto: Making science fun again.
The infrared thermometer: Bisi uses this to measure surface temperatures on everything from slicks to exhaust housings, primary header pipes, racetrack pavement, and intake manifolds.
The Torco oil: Bisi calls it liquid horsepower and uses Torco for increased engine protection, more power, and better heat transfer all from just a few bottles. Recent testing has revealed a 6hp gain on a stock B16A3 versus conventional oil. It's Bisimoto's oil of choice.
The Dynapack: Bisimoto uses the Dynapack dyno for product development, beta testing, and for tuning everything from K-powered Civics to open-air Caterham sevens. The Dynapack is one of the most precise tuning dynamometers to date, allowing for partial throttle tuning, which means tuning for fuel economy just got easier.
The Bisimoto header: Bisimoto's B-series street prototype header incorporates a true merge collector, stepped primaries, and a carefully designed venturi. A similar unit graced the world's fastest B-series all-motor car not too long ago. An average of 15 prototype Bisimoto headers are destroyed in order to produce the most ideal design.
Bisi's brain: With an IQ of 146, an A.A. in applied sciences, a B.S. in chemical engineering, an M.S. in engineering management, and a PhD in engineering in progress, Bisi applies his expertise in fluid and thermodynamics for designing reliable parts for the masses. And you thought you were smart.
The race car: Otherwise known as Stitch, Bisi's naturally aspirated drag car-a 460hp F22A-powered SOHC Honda Insight-runs low 9s at over 147 mph.
The manometer: Bisi uses this mercury-filled manometer (the liquid inside can kill you) for everything from pressure differential analysis to synchronizing individual throttle bodies. The depression of mercury lets Bisi know whether or not runners are too small or too large.

Bisimoto.com: The online porthole into one of the few sport compact-based, high-tech companies that puts an emphasis on science and engineering, not guesswork.
The AEM box: AEM's EMS allows Bisi to use eight fuel injectors to control fuel and timing parameters for each cylinder, and to use individual coils. Bisi also credits his AEM box for dropping Stitch's e.t.'s from high to low 9s.
The Scientific calculator: It's a scientist's best friend. Sine, cosine, and cotangent-it's all there. Isn't science fun?
The Kinslers: It's IRL technology in a street package just for Hondas. Kinsler individual throttle bodies feature latitudinally oriented butterflies that interrupt airflow less than longitudinally positioned ones.
The F-series: Early Accord engines feature amazing head flow characteristics, second only to S2000 heads, and are arguably the most overlooked performance engine in the Honda family. They feature a stout construction and a reliable valvetrain. Non-VTEC is the way to go as far as Bisi's concerned. Can you say K killer?
The measuring devices: Test tubes, pipettes, and graduated cylinders are used to measure precise volumes for scientific experiments, and qualitative analysis of unknown and known compounds, including familiar ones like oil and fuel. The dial bore gauge, calipers, and micrometers are used for taking exact measurements of crank and rod bores during meticulous engine builds-no plastigage here.
The degree wheel: Used for degreeing camshafts, this tool is a must-have for any serious engine builder. When used with an adjustable timing gear like the Bisimoto no-slip version, it allows for proper intake and exhaust timing set up in relation to crankshaft degrees.
The Innovate meter: Bisimoto's LM-2 dual-channel meter measures real-time air/fuel ratios and also serves as an OBD-II scan tool that can read and clear trouble codes and log up to 16 channels of OBD data. It also features a full-function 32-channel data logger, ideal for single-cylinder and collector wideband analysis. In other words, it's a dyno tuner's best friend.
