“Aggressive” describes this new ’99 Mercury Cougar’s design, but the abilities was only “frisky” up until Paxton Automotive bolted using one of the centrifugal superchargers. Along with its pressurized 2.5-liter DOHC V-6 working away a couple-thirds a whole lot more horsepower than just stock, the latest altered Cougar now roars 0-sixty miles per hour from inside the 5.7 seconds-nearly 2 seconds reduced than stock and you will damned punctual to possess a great front-driver. Several obstacles had to be removed until then try you can.
Just like the Cougar’s air-intake is aimed on the brand new transaxle out of brand new transverse-climbed system, the latest supercharger needed to be an engine’s length out-of their push resource. Paxton fixed this from the powering a gear from the motor pulley in order to a chance-kart axle shaft mounted inside the around three bearings prior to the engine. Push was transmitted via other buckle to the supercharger. And then make space toward blower, the stock airbox are substituted for good K&N filter. The device tops out at the 8 psi at the 5500 rpm, to make simply six psi because of the 4000 rpm. Top push-wheel hp sprang about inventory 110 to help you 183, centered on Paxton’s body dyno. That is an unbelievable 280 horses at flywheel!
Managing the spark improve throughout the coil-on-plug Duratec system has also been a challenge. To cease motor-destroying detonation, ignition time must be retarded 0.75 education for every pound off boost. No from-the-shelf services is available to take action which have half dozen separate coils. Since the Paxton’s opposition can still be choosing the address, the firm won’t reveal their service.
Phase step 1 seemed zero suspension system change save yourself to own Toyo Proxes TI Plus ZR18s. Even after severe wheelspin and you will rise from the line, the tips guide signal automobile try an impressive step one.2 seconds less 0-sixty miles per hour than simply inventory (6.cuatro versus seven.6). Skidpad traction jumped a distinguished 0.06 grams, and you will slalom rate increased by step 1.5 mph. The biggest change to possess Phase 2 is incorporating an excellent Quaife minimal-slip differential. That it torque-sensing differential is extremely important to own an enhanced Cougar. Firmer engine bushings from Time Suspension assist maximum motor shake and you will wheelhopbined, so it fell 0-60-mph time to 5.eight moments. Stopping length are step one feet expanded and you may slalom rate is actually the same toward “tires-only” options, if you find yourself skidpad mounted in order to 0.90 g.
But rates will cost you currency: Plano (Texas) Lincoln-Mercury will actually sell you a duplicate to have $38,000: roughly double the automobile’s unique car or truck.-Mac computer DeMere
Corvette TuneupWhen Chevrolet introduced the brand new C5 Corvette into the fresh new slide out of 1996 as the a beneficial ’97 design, the fresh ailment they gotten the best from all of our readers try one the brand new rims and you may fatigue tips did not lookup competitive enough. The readers were not alone. Then-Chevrolet P.Roentgen. guy Carl Sheffer got it on himself to resolve this problem, and result is it ’99 Corvette. Off emerged the inventory throw-aluminum four-spoke rims as well as on ran a set of stock-proportions Fikse billet aluminum five-spoke wheels covered with Goodyear Eagle GS-A tires. This new tires search similar to the construction one to Chevy has introduced while the standard products to the all of the 2000 Corvettes.
To resolve this new unattractive fatigue pipe problem, Sheffer considered Corsa Results for just one of the 50-state-judge stainless-steel-steel exhaust options having shiny resources. The system arrives done regarding catalytic converter back and, centered on Corsa, try an immediate bolt-to your while offering forty-five per cent more disperse more stock. Corsa designed the computer, and therefore uses the Reflective Sound Cancellation technology, into ’98 Indy five-hundred Corvette rate vehicle. About car, i noticed hook improvement in one-fourth-distance elapsed some time a 1-miles per hour obtain from the finishing line over most other ’99 Corvettes we’ve checked-out.
These parts weren’t strung to enhance efficiency (while they perform). The target were to improve already a beneficial-appearing ’97-’99 Corvette search in addition to this. Business well said, i say.
Emotions Variations Pontiac Huge AmWhen the individuals at the Motor vehicle Technologies and you may Construction in the Huntington Seashore, California (-7171), set out to generate the best “very travel” car, it chose a weird guinea-pig: an effective ’99 Pontiac Huge In the morning sedan.

New inventory dos.4-liter five-tube motor heels out so much more ponies, courtesy an Eaton/Magnuson supercharger, K&N air filter, and you can Borla stainless deplete program. Sachs America engineered a set of double varying Professional Fuel shocks to utilize the better-rates coil springs (2.0-inches shed) and you can larger-diameter anti-move pubs of Suspension Techniques. Addressing are then increased by the addition of ZR19 Pirelli rims attached to 19×8.0-inches DAZZ/Race Hart C5 rims.
The surface appearance is actually updated having new front and you can buttocks fascias and front skirts, as well as the required grand buttocks wing, the custom-built because of the AED. On the inside, Ultra Trim did its wonders because of the upholstering this new seats and doorway panels from inside the grey leather and you may adding an offer carbon fiber direction controls security. Good Midwest Sunroof electronic sliding sunroof has also been extra.
