The perfrmance stats for FI Zs are a little dissapointing. It seems that Other factory cars with a similar power to weight ratio as a say Vortech Equipped Z turn in better numbers.
Everyone sites too much wheelspin as the culprit.

Could the Zs drag times benefit from a taller final drive? I remember one member talking about getting the automatic final drive gears for the 350 for when he went FI.
The way I look at it it might transfer power to the ground in a more linear fashion and give longer pulls in each gear.

What say you guys? Possible, feasable, potentially beneficial??

 

Yes it will help . I think Skidazzle has the AT5 final drive in his Z .I seen that it does give higher speed in each gear. I seen the thread in the drag section...look there

 

It's a taller gear in the auto. It gives you more mph in each gear so you won't have to shift at the end of the 1/4 mile. Not good for N/A powered cars necessarily but great for the F/I guys who have more bottom end power and torque.

Good explanation by Fly by Z. I wanted to trade gears with him but he's in Texas and I'm in Cali and neither one of us wants to go the distance.

 

YEah thats who I was thinking of. Thanks for the link. Whatever happened to Fly By Z. He doesnt post anymore.

 

I am keeping my 5AT N/A and want to swap my rear pumpkin for one of the 6MT ones. I should be getting this done within the next month. I just need to arrange a time to get it done. I also agree that FI cars would benefit from the taller final drive and allow them to actually use some of that power instead of ruining tires.

 

Anybody in So Cal wants to trade? I got the A5T Touring with limited slip. Jeff@ Performance Nissan will do the swap for us for around $350. I'll split the cost with ya.
