2000 Saleen S281 Supercharged Mustang Is a Horse on Steroids

From the April 2000 concern of Automobile and Driver.

Saleen Mustangs are unabashed mutants, with bodywork additions that bulge just like the lats on Mr. Universe contestants, with wheels and tires that crowd the wheelhousings, and with engines that pulse with supercharged steroids.

In fact, they’ve additionally displayed a number of the downsides of steroid abuse prior to now, resembling grumpy idling, supercharger whine, a jolting experience, and tramlining on longitudinal grooves badly sufficient to make a bloodhound dizzy. Additionally, beneath the duress of our testing procedures, some examples of Saleen’s handiwork have even, uh, did not go ahead.

However this S281 you see right here appears a zebra of an altogether totally different stripe. Utilizing the overhead-cam 4.6-liter V-8 as a base, and using a Roots-type Saleen supercharger a lot quieter than the one we final sampled on Saleen’s S351R (C/D, December 1996), the 2000 S281 is com­paratively civilized in nature.

It begins simply and idles easily. Though the two.5-inch-diameter stainless­-steel exhaust system utters a notice clearly deeper and gruffer than you hear on the inventory Ford, it avoids being obnoxiously boomy, particularly at low rpm, the place this downside typically turns up on aftermarket pipes.

The clutch effort is cheap, and the short-throw shifter that Saleen bolts on works fairly nicely, significantly once you keep in mind that the usual five-speed transmission is not the slickest within the enterprise anyway. Low and midrange torque are glorious, offering shiny throttle response in nearly any gear. You’ll be able to depart the visitors for lifeless with out breaking a sweat, however the S281 engine will even zip by way of to its 6000-rpm redline with no signal of reluctance alongside the best way. Maybe that is what you’d count on from the over­head-cam engine, but it surely’s undoubtedly helped right here by Saleen’s cast-aluminum consumption manifold and high-flow (24 kilos per hour) gas injectors—all managed by customized fuel-delivery calibrations.

The final supercharged Saleen we examined (C/D, August 1998) suffered from the dearth of an intercooler, however the S281 takes no possibilities right here and wears an air-to-water intercooler squeezed into the engine bay. Saleen claims 350 horsepower for the automotive on this kind, up 90 hp from the inventory GT’s 260, and 65 greater than Saleen’s personal naturally aspirated S281.

That is a colossal bounce, and though the automotive feels considerably stronger on the highway, our check outcomes do not present onerous help for these horsepower num­bers. Sure, our quarter-mile time of 13.8 seconds at 103 mph is kind of a bit faster than a inventory Mustang GT’s 14.2 at 98, however is it evi­dence of 350 horsepower? Not likely. Saleen’s pub­licity materials quotes some efficiency figures pub­lished by one other maga­zine, declaring it went from 0 to 60 mph in 4.8 seconds and turned the standing quarter in 13.4 seconds at 108 mph.

We guessed these may need been easy one-way runs, maybe with out climate correction. However once we appeared extra carefully on the num­bers, we found that our launches have been higher, with fractionally faster occasions to 30 and 40 mph.

For the reason that supercharged S281 must be bogged off the road (the clutch have to be engaged at low revs to keep away from time-wasting wheel­spin), this efficiency disparity thus seems to be a pure energy concern. Much more telling is the efficiency of our personal tremendous­charged—however not intercooled—venture Mustang GT (C/D, July 1999). We mea­sured 278 rear-wheel horsepower on a dyno, which interprets into about 330 crankshaft horsepower. That automotive—with 20 much less hp and about 150 fewer kilos than the Saleen automotive—hit 60 mph in 4.9 seconds and blew by way of the quarter-mile in 13.6 seconds at 103 mph. Maybe this S281 was only a sluggish instance—who is aware of?

A reasonably honest enhance in energy is obvious at larger speeds. The S281 reaches 100 mph 2.1 seconds faster than the GT. And extra convincing but is the sprint to 130 mph—it is a full 13.5 seconds faster. The supercharged engine additionally has the grunt to tow the spoiler-festooned S281 to a high pace of 154 mph, beating the inventory GT by 16 mph. Given the additional spoilers and scoops, that velocity enhance makes the 350-hp declare extra credible.

And from the motive force’s seat of the S281, there’s an unmistakable enhance in torque that’s obvious in all driving conditions. In fifth gear, the S281 accel­erates from 50 to 70 mph in 8.5 seconds, 1.4 seconds faster than the inventory GT, which has a 3.27:1 axle ratio that’s extra con­ducive to acceleration than the three.08 axle used on the Saleen. Couple that with the great suspension and wheel-and-tire upgrades on our automotive, and also you get dynamics within the realm of race vehicles.

On the skidpad, the Saleen swooped round at a giddy 0.92 g, displaying res­olute roll management and minimal understeer. Out on the observe, the automotive (geared up for our check with non-obligatory 10-inch-wide rear wheels and 295/35ZR-18 Pirelli P Zero tires, price some $995) has such good grip and such ferociously fast turn-in that it makes the inventory Ford steering really feel further­ordinarily quick.

Cough up one other $2600, and you may demand 13.0-inch grooved entrance discs with four-piston calipers to go behind the Saleen five-spoke alloys. Our automotive wore standard-issue Saleen brakes—upgrades from the inventory Mustang—and these have been good for stops from 70 mph in simply 160 toes, a notable achievement for a 3540-pound automotive. With the sticky tires and nicely­-tied-down chassis, this all provides as much as a scarily quick automotive on the observe. We needed to restrain ourselves at our transient observe session to maintain the crimson mist at bay and to guar­antee an unwrinkled automotive on the photograph shoot.

It isn’t that the Saleen S281 has any nasty surprises up its sleeve. It is simply that the cornering speeds are excessive sufficient to make any little lapses of focus doubtlessly costly ones. Naturally, the aggressive setup compromises the automotive’s experience on tough surfaces, the place it hammers and jolts over the worst floor imper­fections. Owing to its urethane bushings, the experience just isn’t quiet, both. And—as anticipated—the stable rear axle does its typical dance on corrugations in addition to its oblig­atory wag on massive one-wheel bumps.

However for what it’s, the S281 is surpris­ingly usable and completely able to com­muting and touring roles. And at $33,182 with the supercharger however with out the wheels and tires, it is not wildly unafford­in a position. Hey, that is 350 (or so) horsepower and a race-bred chassis for 33 giant. Is that this an important nation, or what?
