mini spool and 3.9's in vs commodore

[tbblitz]

im thinking about getting a mini spool and 3.9's in my v6 vs commodore.
Just wondering if i get this done what will my car rev range sit at on 100kmh.
Also will it kick in the auto drive at 100kmh. My mate has 345 and it goes on and off with his over drive doing 100kmh.

Also how much is my speedo going to be out and how much is it to get it re adjusted.

Thanks

235/40/18 3.7 diff =2343rpm
235/40/18 3.45 = 2184rpm
235/40/18 3.91 =2476rpm
can't see why it wouldn't but I'm no expert
enough to lose your lisence

Diff places all have percentages so for instance 3.7's will change your speedo reading by 12% or something.

You can either keep that in mind or you can get it fixed professionally by the diff place or someone they use.

minispool gonna be a biatch to drive on the road, the back end won't like going around corners unless you spin the wheels etc. it'll feel like the car is suffering from under steer and the back feel like it's hopping, like diff chatter

im not a fan of mini spools on street cars unless you have money for new back tires every few months. they tend to choo the fu*k outa the tires.

VN 6cyl has a openwheeler, 28sp, 4pin center, with 28sp axels and a 3.08 ratio.
On the street, open wheeler, anyting above 3.45 is usless as you will have too much wheelspin. 3.89, 4.11 are also pretty usless on standard engines as they dont have the high rpm power to keep pulling at higher speeds.

3.45, nice average, 3.7 max on a street auto with a stockish engine, 3.89 or 4.11 locked, nice burnouts

Keep in mind that your speedo needs correcting after a gear change.

Diff gears,

me personally id go 3.9's to get the car of the line, due to the car hasnt got the torque from a v6, fuel economy wont be much of a difference between between 3.7's and 3.9's.

If auto the car has a lock up convertor so u wont be reving to hard at 100km/h, if manual you will utilise the 5th gear better.

Normally you will find better fuel economy around town from changing diff gears, cause your taking alot of the load of the engine, hence its working better.

enhancedss said that last quote about a manual VP V6.
hope i helped
