The '1986Shelby GLH-S'was a modifiedDodge Omni GLH, with changes made at the Shelby factory. They were retitled as Shelby Automobiles cars sold at select Dodge dealerships. GLH stood for "Goes Like Hell" and GLHS stood forGoes Like Hell S'more.Just 500 were made.
Dash plaques used a 3-digit serial numbering system (as only 500 were made).
TheTurbo Iengine was modified with pre-production pieces from what would become theTurbo IIinline-four engine. These changes included anintercoolerand other changes to produce 175hp (130kW) and a flat 175ft·lbf (237N·m)torquecurve. Not included were any of the durability changes to the short block (forged crank, full floating pin, stouter connecting rods, etc.) of the 1987 ChryslerTurbo IIengine. Luckily, the Shelby engines have proved to be reliable even without the durability enhancements of the productionTurbo II. Performance was impressive, with just 6.5s needed for 0–60mph (97km/h) and 14.8s for the quarter mile (402m) run. Top speed was 130mph (209km/h).
Shelby Automobiles received the first T-2 induction pieces (prior to Dodge/Chrysler), and installed them on the 500 GLH cars that shipped to the Whittier factory. Engine mods. included: New T-2 fuel rail, T-2 injectors, wiring harness, larger throttle body, bigger turbo, tuned intake & exhaust manifolds, intercooler/rad. & fan assemblies, induction hoses, T-2 airbox, GLHS specific logic module,CS-Shelby-CSwindshield decal, & tape graphics pkg. Interestingly, there was a Dodge emblem left on in production. A black/yellow overlay sticker was placed at the bottom of the speedometer to read to 135mph (217km/h). A Momo leather-wrapped shifter knob, Izumi leather-wrapped steering wheel, and shift pattern sticker were also installed. AUse only Mobil 1 in your GLHSplaque was affixed to the front of the standard production valve cover.
The primary differences between the Shelby engine and the Chrysler Turbo II engine are the torque: Shelby's unique engine computer shaved the torque to save the stock Omni transaxle, Chrysler Turbo II engines had 200lb·ft (270N·m) of torque; the trimetal bearings, forged crank and extra oil passages weren't present; and the wiring harness is a conglomeration of original Turbo I, with splicings for the heated oxygen sensor.
All-in-all this was a very formidable car, especially on short tracks. In SCCA Solo competition, it was never allowed a place in the stock categories because it failed to meet the required 1000 unit a year production quota. It also was significantly faster In the quarter mile than the Chevrolet Camaro with the 305 V8, Pontiac's Firebird/Trans Am with the 305 V8 and pre-1987 302 V8 Mustangs, and equal or slightly faster than the 1987–1993 V8 Ford Mustangs and Corvettes.
