3.15 Performance???? Need help ASAP.
I have tried the search, but no matches were found. Now I am used to F-bodies. When you have an auto, you always want 3.42 gears, preferably higher. But I'm wondering, since the vette is lighter, would I get away with using a 3.15 gear and a 3600 stall?
I need to know performance results for anyone that has 3.15 gears, what mods are done, and what stall you have.
I will be adding heads/cam. The cam will be something like an MS3. Just to give you an idea.
Again, really looking for performance results of 3.15's.
Thanks for your help,
Austin

My best run was in the mid-high 12.8's. The only mods were Halltech Stinger and a tune.

All I can tell you is if you step-up to a 3.90 gears and a Yank 3600 to 4000 stall converter, you will pick up at least a .5 tenths of second (a full 1/2 second vs. any conveter and 3.15 gears). The fastest stock cubed heads/cam C5 autos that have run consistents 10s N/A, run 3.90 gears and between a Yank 3800 and 4400 stall converter.
I have been there and done that owning a heads/cam stock cubed 98 C5 Roadster that ran mid 11s all day long with 3.73s and a Yank PThruster 4000 7 years ago (with only 370rwhp).
With a ballsier cam like your running you need that edge to propel you out of the whole and the 3.15s won't get it done in my honest opinon.
The fastest 3.15 stalled up h/c N/A C5s are probaly running mid 11s (tops) and the set-up I suggest should get you 10s all day, with good sticky tires of coure like et street or et street drag radials!
