I hear ya. Once you get above 120 in some vehicles, it's white knuckles for sure. But I recall the first time I did 140 in a 94 9C1 Caprice. The thing was smooth along I-70 as we had to go east about 40 miles to a trooper in distress call. We hit 144 MPH and then it just stopped accelerating. Felt like it had more power to go faster. Limiter, I suppose. One of the only times I've been over 140 MPH. But it was a nice increase over the 133 MPH that the old 91-93 Scuds (Caprice with the standard 5.7L non-LT1) would top out at. And definitely an improvement over the 115 MPH that the 89 and 90 Caprice box cars would get to. The later year Crown Vics (98+) seemed very smooth at high speeds too, they just took forever just to get to 130. My department did have a few of the 97-99 Tahoe Police Package 2WDs for awhile until they decided that Ford's were not so bad and went to the Crown Vic and eventually the Taurus and Exploder. The 2WD Tahoes were good to 135ish. But when you add a transfer case to the mix, I worry about those things failing. most Transfer cases are not rated for high speeds. My department ordered about 20 new 96 9C1 Caprices, but made an error and selected a tire with lower speed rating on it which meant the factory programmed top speed limiter was set much lower. 120 MPH. Where we were at, hitting speeds in excess of 130 MPH out on the highways was common when responding to backing up fellow officers, troopers, and other critical needs. We did allow persuits as well, but under carefully monitered guidelines by the shift supervisor and watch commander and of course your own best judgement.
