Ok, a little miss information, and qestions flying about, so I will try to clear that up.
The Dodge Omni GLH could be had in a carbed or turbo form in 85' and 86'. THe 84' GLH was just carbed and did not have the ground effects which the later models had. They were a dealer option that became the production pieces the following year.
The Turbo GLHs, which most now refer to as GLHTs were a draw through non-ICed setup. They had 146HP. The 86' GLHS which was based off of the omni was a blow through design that was ICed. They made 500 86' GLHS cars, which are not to be confused with the 87' GLHS chargers of which 1000 were made. The GLHS had 174HP, which was conservative for the motor due to the fact that Shelby limited the boost, as the A525 trans in the car is rather fragile.
I show the 86' GLHS as running between 14.8 and 15.3. I would immagine that the GLHT would run a mid 15 in the quarter. No where near the perfomance of the GN, but bang for the buck is unmatched.
For those looking for one cheap, you had better get on it. Good condition omnis are getting hard to find and the price is really going up on them. A charger would be easier to find, since they made them until 87'. in 86' They only made about 1800 GLHTs.
