u think the 350evo gears would b too short to use w/ a 75 shot?

 

Was thinking of going the same route...

The increase on the non-juice runs will help take the edge off the need for a SQUEEZE!

 

Show - Well, I have the factory 3.23 open diffy in my A/T G ( w/2800 rpm T/C ) & U better have a window switch or the NX Maximizer ( as I do ) because I'm up to a 100 hp shot & there's NO traction to be found the way I have the Maximizer tuned right now! I haven't changed the settings from the 75 hp shot which were to gradually ramp the squeeze in starting @ 3k & fully in by 4500 rpms. At these settings, the nitrous would barely haze the tires once they stopped spinning from the higher stall T/C flash stall of 3k. Now w/the extra 25 hp jetting I get sideways when the nitrous comes on ( in 1st gear ) & if I continue thru into 2nd, they'll break loose until I reach roughly 4200 rpms. Granted, this is on Nitto Extreme street tires but I need to plug my PDA back into the Maximizer & change the initial ramp percentage ( the Maximizer is as amazing piece of tuning electronics!! ) to something smaller & possibly change the ramp time as well. Based on this, I don't see how U'd be able to get the power to the ground w/the 3.9's!! I hope the soon-to-be-available ( we think ) Quaife LSD will help.

 

thanks 4 the info. i'll try it w/o at 1st, then probly make a decision.
