What if you change your final drive and later get FI. Is this recomended or not?? Would you lose your rear end every time you change gears? I think it would be less pressure on the other mechanical parts but you would redline very very quickly.

 

I'm not planning on going FI but I think the two would complement each other very well.

 

Lots of SC guys have lower gears, since the SC doesn't provide much boost at low RPMs.

 

BTW, please check this out.

 

Both Jenner and xviper have 4.44 gears and SC.

 

ive read some posts about how people can chirp their tires easily with just the 4.44s, But then ive you add a SC Or turbo You would need to get that power to the ground. i would think that there would be too much power especially with the better throttle response that the gears give to do so. Id think that you would spin for a while getting off the line. Or is there an ideal rpm to launch at? Also, you would hit the redline before you know it. How is the shifting with both of these mods together. id figure it would be a real pain in the rear after a while.
People out there that haqve these mods done please comment.

 

This thread isn't going to generate much interest with a title like "Anyone thought about ...". Send Jenner and / or xviper a PM.

 

Pm sent. Id like as much info and experiences about this as you guys can give.

As most people know, I have both the 4.44 gears and the Vortech. I went the route of gears first, then S/C. I've been a great proponent of doing the gears. This is a great mod for better driveability and low end grunt. I especially have been a proponent of having these gears before or at the same time as adding a S/C. A S/C can add a considerable amount of stress to the drive train. Having a higher F.D. ratio makes this stress a bit more manageable. Everything "upstream" of the diff works a bit "easier" with the "gears".
I will not deny that getting power to the ground becomes a bit more of a challenge, especially when roads are moist, tires cold. "Launching" becomes more of an "art form" with this combination and much care and finesse should be excercised. How do you suppose a top fuel dragster or a funny car driver handles nearly 3000 HP? These cars have more than enough power to spin the drive wheels all day long. It's the driver that learns to control this power to benefit best performance.
I've never had any trouble chirping the tires on a 1-2 shift when stock. Doing so with 4.44's became even easier. Add on the S/C and it can be child's play.
You know what they say - "With power, comes responsibility." If you are having trouble controlling this car stock, getting gears and then a S/C, you will scare yourself out of a few years of life.
And YES, you would redline very quickly. If you thought 6000-9000 rpm comes fast stock, it will boggle your mind with gears and S/C. A shift beeper is almost a must as well as getting real good as shifting fast. This is not just a case of making the car "keep up" with other cars BUT one of the driver keeping up with his own car.
There are other responsibilities that come with this combination - the "care and feeding" of the rear end and S/C as well as the car in general. Failing to do so will more than likely result in a broken car.
