How good is this gearing for my car? I would like to know what the 0-60 is, I havnt driven the car since I drove it home on Saturday.
If the car didnt have the Brougham package, I would be stuck with 2.53 gear's, vs. the 2.93 I have now, according to the technical specs in my manual.
Someone said that the '95 Buick Roadmaster Limited had 3.08 gear's, and it did 0-60 in 6.7 seconds and the quarter of the mile in 15 seconds.
I can tell you, off the line, it is phenominal. I'd be curious to see what the number's are, now that I actually OWN a Fleetwood, instead of asking, thanks! :bouncy:

The 2.93's are okay but 3.73's are better :lildevil:

I had a 1995 Roadmaster Limited with 138k miles on it, i had the 2.93:1 Posi Rear Axle instead of the standard 2.56:1 non posi, and that car was quite fast, i'd tied a 2003 Saab 9-3 Turbo Convertible, and a 2002 Dodge Stratus Coupe V6 to sixty and both of those cars 0-60 times were about 7.2 or 7.3, so with 234 more pounds than my roadmaster (4478 v. 4244) i would imagine the 0-60 being around 7.6-7.8, i remember reading cadillac's estimates for the 0-60 time of the 1994 FWB with the 2.56:1 being 8.2 so it's faster than that, hopefully under 8.0!
I have read the 2.56 cars are o-60 in 8.2. So I would expect the 3.08 and 2.93 cars to be faster. I just bought a 3.42 (V4P) car, I will hopefully find out!
How do you do a 0-60 time in a traction controlled car? Turn it off or allow it to fight you?

2.93's are going to be pretty slow still, though quicker than the 2.56. The 3.08 is still taller than these fleetwoods need. The 3.42 is really about the best overall, though a 3.73 will be a bit quicker. As for 0-60 tests, turn off traction control, and get used to launching it. The stock TC is way too conservative.
Has anyone on the list gotten the code off of the TC and decoded it? Scott Mueller has a list of the stall speeds on one of the 9C1 sites. The Impalas are just a hair under 1400 rpm stall.
Is it the same converter as the Impala SS?
Is my V4P car going to have a different TC than a 2.56/2.93/3.08 geared car?

I've heard that the % change in rear-end ratio is equal to the % change in torque at the rear wheels, is this true? So therefore, going from 2.52 gears to 3.08 would put 22.2% more torque on the ground? I'm wondering this because I've read different reports on the 350 in my 90 Brougham and I'm pretty sure one isn't right. According to auto.consumerguide.com, I'm making 300 ft. lbs at 2400 rpm and about 175 hp at 4200 rpm. Another site however, says I'm making 400 ft. lbs at 2000 rpm but still 175 hp at 4200 rpm. The compression ratio is 9.3:1 in a stock 350 with a very mild cam, so I'm pretty sure it's got to be 300 ft. lbs, but does anyone know where 400 ft. lbs could have come from?
