Final Drive FI gearing: What's yours?
 

Looked around for a thread on this and didn't find a collection thread listing what final drive gearing FI cars are running and the results. It would be nice to have everyone's info in one thread for quick/easy future reference of others.

If there is another thread like this, please point me to it....but I spent 20 minutes with the 'search' button and didn't find what I was looking for.

I think it would be helpful to have the following info in each reply, I'll start.....

FI type: Vortech V2 SCI-trim
engine displacement: 3.5L
rwhp: 385
6mt or 5at: 6mt
rear tire size: 275/35/19
LSD type/brand/settings: OEM VLSD
half shafts: OEM
ring/pinion gearing ratio: 4.083
typical use: street & occasional track day (road race)
likes/dislikes regarding gearing: can't build boost in 1st gear before hitting rev limiter. Can only build 3psi in 2nd gear before hitting rev limiter. Can't hook up in 1st on hard core launches even though both wheels are pulling for the most part
plans to change final drive: Yes! Have 3.53 gears with Nismo diff set to 1.5way @ 60% lock. Installing it this week.

The type of tire is important also.

holy crap, thats a lot of gear for primarily street use. dont blame you for going down.

The gears are left over from the n/a mods before it went f/i. With a trailer hitch, I think she could pull a 5th wheel right now.

:driving:

I believe it. what was your usual RPM around the streets? Gas mileage must of suffered quite a bit.
