SR Archive: Team Mr. Honda CBR900RR Turbo - UFO 1996

Lean, mean and stripped clean

This article was originally published in the October 1996 issue of Sport Rider.

Ever notice how Texans always do things a little differently? Take Mike and Tracy McIntyre, a.k.a. Team MR., of El Paso. In planning their ’95 Formula USA assault, they went with a Texas-size helping of horsepower; but rather than use conventional big-engine wisdom, they decided to turbocharge their roadracers.

The Team MR. turbo application utilizes a relatively small turbo unit and low boost for minimal turbo lag and usable horsepower levels. The McIntyres claim that if you lay one of their turbo bike's dyno charts over that of a stock Honda CBR900RR, it never dips below stock, and builds in a linear manner in an ever-widening gap to its 215-horsepower peak—roughly twice that of a stocker. All these gains are achiev­ed with mostly stock Honda internals, and the basic turbo kit goes for a relatively reasonable $3995 with a set of forged pistons for racing applications adding another $320. The Team MR. CBR's off-boost power delivery is crisp, thanks to stock compression-ratio pistons, and it builds boost more smooth­ly than any turbo we can recall.

Dunlop’s D364 wraps around a polished 6.25 x 17-inch Marchesini wheel for a sticky, lightweight and wide combination. The Texas team came up with a clever and strong solution that allows up to six inches of additional wheelbase and a simple ride-height adjuster on the rear linkage as well. It’s all available through Team MR.Sport Rider

At first we didn’t know what to make of the Team MR. Honda’s stripped-down, insect-like appearance, but the first time we flicked it into a corner it felt instantly familiar. Despite the lack of wind protection and gauges (save a digital temp gauge, though we’d prefer full instruments), it pulled a close first-place ranking in the street section. It also astounded everyone by running a 9.03-second, 154.6-mph run that would have been a UFO record had the Hahn Racecraft GSX-R1117 turbo not bested it. The McIntyres lowered the bike and ran three inches over on the wheelbase for the run. Its 350-pound dry weight made it the lightest of the bunch and no doubt helped in every measure of performance.

Team MR. reworks the stock fork, swaps the stock 16-inch wheel for a 3.75 x 17-inch Marchesini shod with a Dunlop D364 radial. Top-shelf Brembo four-piston calipers and floating 320mm rotors serve up serious stopping power. The adjustable triple clamps come from Indigo Sports and the radiator is stock.Sport Rider

At the road course, the Team MR. machine ran an impressive 1:50.7 lap time, topped only by Hyper-Cycle's record-setting fast lap. It's easily the most ridable turbo we've had on a road course, though, and its handling manners are nothing short of fabulous. It was the top-speed event that broke the CBR900RR turbo's impressive string of top-two finishes when, we assume, aerodynamics won out over horsepower. Our testers had a hard time holding on against the windblast and would have liked a tachometer to gain valuable shift point and gearing information. Try as they might, their best was 187.110 mph; certainly fast, but somewhat of a disappointment considering the bike's otherwise strong showing. On what was shaping up to be its fastest run, the Team MR. machine lost power in sixth gear with what was later diagnosed as a detonated piston, which in turn fouled a plug with piston material—a relatively understandable failure considering the abuse of more than 20 dragstrip runs and close to 10 punishing top-speed runs. Team MR. created one of the best all-around UFO bikes we've ever tested, and a few minor changes (bodywork and gauges) would have made its entry even stronger. Just how good is the Team MR. CBR900RR turbo? Good enough that the former anything-goes Formula USA-series decided to ban it from competition. And good enough that it's forever wel­­come at UFO.

The heart of all that horsepower is a surprisingly simple DragonFab 4-into-1 exhaust bolted up to an IHI Warner-ISHI 5T504 turbo unit rated at 265 cfm. (A muffler and tailpipe are also included.) The system’s short headpipes and small turbo produce minimal turbo lag and can be installed in a few hours, according to the Team MR. crew.Sport Rider
