This reminds me of an incident about 22 years ago but not with a V8 truck, it involved a 1996-2002 Pontiac Firebird WS6. You remember the ones with the quadruple opening, ram-air hood? Longer story warning...at the time I owned a 1995 Ford Ford Es cort (Ford E s c o r t...keeps changing to econobox) GT that I had modified using the turbo and manifold from a Mazda 323 GTX. It really wasn't anything special with a crush bent 2.5" exhaust. Ignition was slightly advanced (14 degrees) and under boost, it was retarded using a Jacob's Boost Timing Master if my memory serves me. It also had larger injectors (RX7?) and I learned an Apex'i S-AFC could be used in conjunction with an MAP sensor wired in place of the throttle position input wires to reduce fuel enough to make the OBD2 ECU happy during idle and cruise conditions yet provide enough fuel for 14 psi on the small, VJ-20/21 turbo. It was a low 14s, ~100 mph quarter mile car. I only raced it one night on an Akron Ohio drag strip against a friend's, unmodified Ford Econobox GT. I wasn't launching hard because I had to drive 13-14 hours home the next day. I think it ran 14.3 seconds at 97 mph which was more than 2.5 seconds faster than my friend's E-GT.
Anyway, I was living in NE Ohio and dating a women in Erie, PA that I met on Yahoo Personals, LOL! One day I was on my way to meet her when I remembered there was an upcoming interchange, a fun 270 clover leaf. I was planning on pushing harder through the turn and accelerating WOT down the long ramp onto the next highway. I'd guess 14 psi gave me ~225 HP (engine rating, maybe 200 WHP). Unfortunately, as I approached the clover leaf I saw a minivan signaling to take that exit. It was pokey slow, ~25 mph through the turn. I stayed back knowing I could easily pass at the end of the on ramp.
Sometime between entering the exit lane and the long on ramp, I noticed a red flash coming up hard in my rear view mirror. I waited patiently for the white double line to end and I signaled and moved over behind the van checking traffic and signaling again. I wasn't WOT, not near full boost but not poking along finally clear of the van. As I was signaling my second lane change the red car caught up and made an extremely early lane change thinking he could blast down the longer on ramp and jump around both of us. I saw that I was in his way, downshifted and hit 14 psi pushing as hard as my little 1.8 4-cylinder could go. Mr V8 braked slightly and by the time he got back on the gas, realized I was pulling away and he wasn't able to catch up and push me along. I must have hit 85-90 mph as I signaled to move back over. Mr V8 blasted past probably hitting 100+.
I wasn't racing, just bad timing on his part put me in a bad position and traffic was light. I drove calmly to my exit and what do you know, the WS6 took the same exit and I ended up one car length ahead of him in the left of two left turn lanes. He revved to the limiter and seemed frustrated. My car was a darker green, not quite seafoam green but it had one of those cheasy, 90's vinyl graphics down teach side of the car (purchased used, came on the car as a dealer option). You might remember the blue/green "JAZZ" design that was common on paper cups? That was on the side of my car so there was no mistaking me. As the light turned green, Mr. V8 again revved near or to redline and tried to shift into 1st gear before engine speed dropped resulting in loud grinding noises. As I pulled away with the windows down I burst into loud laughter.
Mr. V8 was upset my little Ford Ford Econobox was a close match in power/weight. For not having an O2 clamp and piggyback fuel/spark controllers, plus a poor quality exhaust (no shops wanted touch it, "need back pressure or you'll burn valves"), that car was quite the sleeper. Another time driving through Chicago in the middle of the night, an SRT4 and Saturn Ion Redline were racing, holding up traffic. I was tired after 7+ hours and wanted to get around and away from them. Once they noticed my Ford Econobox was able to keep up they wouldn't leave me alone. I sold that car around 2007 and missed having a turbo until 2019. Now my highly modified, soon to be ~275 WHP Mazdaspeed MX-5 fills that void!
