whenever I research my car year, they are always listing results with a 6-speed trans. I want to know what times a 98 c-5 automatic with the performance axle ratio is capable of. Both 0-60 and 1/4 mile. Thanks
Just in case you're loking for 0-60mph, My wife's auto with 2.73 (not your 3.15) ran a best of 5.18 before we started "tweaking"
Is the 2.73 faster in 0-60 than the 3.15? I would immagine that the 2.73 gets pretty close to 60 in first gear. I know that the 3.15 has to shift before then. I would think that the lack of shift would be a big difference with the torque management.
The 3.15 is noticably quicker than the 2.73 axle. With just a open element air cleaner you should be low 13's. If everything is perfect you might even eek into the 12.99 range. the stock C5 air cleaner strangles the LS1. Chuck.
i ran a 13.2 @ 106 2.0 60', i have a callaway honker intake and used the 18" dr's off my z28. i was hoping for better times, but it was close to 100 degrees that day, so i hope with some cool weather 12's are possible
Ive only made 1 pass in my 98 C5 (a4, 3.15) and it was a 13.66 @ 101. The night of the pass was pretty warm and humid. Even with a 180* tstat, my engine temp was at 225* at the time of the pass. The only mods on the car was Borla Stingers, 180* Tstat, Cold Air Screens, and Falken GR-Beta Tires. I know it has plenty more in it, but it was too crowded and hot that night to make any more runs. I'll probably go back once it cools off.
My drove his 99 Bone stock C5 A4 w/ 3.15 rear end(stock) ran best of 13.4 @ 104mph.
If I get an "open air" filter will I need a tune. Sorry I'm a newb to the
Ls1 world. I bought the car from my dad this week and I want to do some basic mods. Oh the 99 has just 7,900 miles on it. Still bone stock
