How to run a 14'* with a 92-94 non-sc'ed 3800
Hey, my first post on this site!!
Anyhow, 'back in the day' (how I miss it -oh, yeah, that'* why I'm getting another Bonneville) when I was driving/pimpin in my 92 Bonneville SE before it was rear-ended in May I had done some modifying to it so I could run it at the track and show it on the boulevard.
For power I had cut the catalytic convertor out and put a straight pipe in it'* place, put a cheap $15 cone filter on, NGK v-power plugs, 9mm wires, and a 180* t-stat. I always ran 92-93 octane gas and Mobil 1 10w30 motor oil.
I am guessing the with the mods my engine was probably putting out around 200-210 hp. I say that because raced my friends 1995 Bonneville SLE about a dozen times and I always beat him by about two car lengths in a block.
With these mods done to the engine and no stripping of the interior or trunk I could run a 15.1 @ 87 on the G-tech. After stripping the trunk, back seat, and the majority of the interior trim I ran 2 times with the G-tech. The first one netted a 14.6 @ 90mph , and on the next run I got a 14.7 @ 92mph with a bit of wheel spin. Would probably have had lower E.t'* and more mph if I hadn't been using the heavy 16" vogue rims and 235/60/zr16 custom built radial tires. They weighed 5 lbs more each versus a factory 16" rim with a 225/60/16 GoodYear Eagle GA.
Anyhow, I have got to say, that I was very happy considering the car weighed 3556 lbs with a full tank of gas, and me (150 lbs) at the local truck weighing station. After stripping it and only a half tank of 93 octane it weighed 3203 lbs.
Some people might laugh a stripping a car, but every 10lbs you strip from your car is equal to gaining 1hp without stripping. Therfore, I would have gained the equivalent to 35.3 hp (I had stripped 353 lbs from the car).
Hope this helps those who are wondering how to get the most from their 1991-1994 3800.
