What was the cost and how much was the install?

 

It comes down to two factor's really...

Plenum adds... Horse Power & Sound...
Final Drive Upgrade adds.... Acceleration & Changes the over all Performance of the car...

Adding the Plenum will please the driver as far as sound and pull a bit harder...

But, Compare that to changing the Final drive gear in the car... Not only does it add acceleration... Driver reaches Higher Speeds faster while shifting more giving the driver a subconsious feeling like more is going on and adding more of a driver upgrade to added power...

It is like adding the light weight flywheel, not only do you improve getting power to the wheels, the car is over all more responsive making it more EXCITING to drive then adding an extra 20HP and feeling like you are waiting for the motor to catch up to you on Down Shifts / Up Shifts... (sorry but after the tilton, driving the stock Z is YAWN)...

So... If you are looking for something that is going to make the DRIVER FEEL more EXCITING then change your drive train...

If you can shift lightning fast and have a light weight flywheel / crank pully on your car then the final drive may improve your 1/4 times...

On an AT if you do the 3.5 gear upgrading the Valve Body of the trans (stillen unit) is a must to add to the driver satisfaction...

Just my thoughs.....

 

Jason anyone MAX out the STREET pack for the Tilton yet??? Im preping for a Turbo kit and need to adjust boost for MAX WHP.....

 

Tilton and the Final drive is insane....I droped .3 seconds off the Final drive..... best mod ive done besides Flywheel

 

Jason, have you dealt with anyone who has installed the upgraded valve body from Stillen? That is next on my list so Im wondering what to expect from it.
