Ok so a buddy of mine has this installed in his car. He HATES them (takes roadtrips and stuff all the time)

Are these worth grabbing from him? He said that he will give them to me if I pay for install..... sounds like a killer deal.


Up sides? down sides?

Dont' know much about gears.

Are the 4.44 gears strong enough for a supercharger?

 

You mean swapping diffs?
Gears (final drive gears) are installed in the (rear) differential.

Taking his 4.44 gears (ring & pinion) out of his diff does not take any installation.
Putting the OEM ring & pinion back does.
Without "gears" any diff is kinda useless
Same goes for you, installing a 4.44 ring & pinion in your diff takes installing.
(taking the OEM set out is the easy bit)

Swapping differentials would be the easiest way.

Your friend has 4.44 gears, so go for a drive in his car.
You may find out for yourself if you like 'm.

Up : better acceleration in any gear (transmission)
Up : FUN!
Down : more revs => more fuel => more noise.
(fuel may be better for city driving)

If they are strong enough?
Heee xviper?.. O Brother, Where Art Thou?

 

Eh, ricks doesn't make a 4.44. They make a 4.57

 

the revs between stock 4.10 and 4.44 are very little -- 300rpms maybe per gear?

I wouldn't worry to much about that downside

 

so are 4.44 even worth it?

 

It is likely that those 4.44s are J's. I've had them in my car for many years, along with the supercharger. Never a problem with them. 4.44 gears will give you an 8.3% gear reduction or in other words, an 8.3% increase in low end grunt. If he's willing to swap diffs then do it. That would only take a professional about an hour or 2 to do it. If he wants you to pay to have the gears actually taken out of his diff and put stock ones back in and then you have to pay to get them put into your car, this becomes a fairly expensive proposition. Still, nowhere what it would have cost originally to buy J's 4.44s, which were about $1400.00 5 years ago.

Why does he hate them?

 

This statement makes very little sense because there is no point of reference.

 

Sorry I mean't to mention that the comment was about gas milage. Higher revs = higher gas consumption but its hardly anything to worry about with the 4.44s

 

That's a more understandable statement. In fact, even though the 4.44s increases revs by 8.3% at any given speed, my highway mileage dropped about 10%, however, I should add that the supercharger may have accounted for some of this. My normal highway cruise rpm varies between 4500 to 5000 rpm, which is just under any significant boost, but also consider that the supercharger still contributes to reducing the normal manifold vacuum at that rpm.

 

He told me that he doesn't like the higher rpm's. He takes roadtrips all the time.

This guy todl me they are rick's gears. And he's has a ridiculous amount of J's parts..... so I think he knows they arent' J's.



so the power delivery increase is noticable?
