Thinking out of the box......

The difference between my 3.6 and 3.0 is remarkable, but they both have a pleasing personality...kinda like riding a stallion v. riding a well mannered but nimble horse......

What I'd like to hear is if anyone has ever taken the 930 4 speed tranny and put it in a 3.0 N/A......I think that looooonnnggg first gear would be beneficial......

TIA....

Isn't 1st gear pretty tall in a 930? I would think the 3.0 would benefit much more from shorter gearing, not taller. I don't know much about the 930 though.

I'm not happy with the 'short' duration of 1st gear.....I'd like to really spool this thing up to speed before shifting, as is the philosophy behind the 930....

With taller gearing you can shift later, but acceleration suffers. The car will be more sluggish. The turbo's boost allowed that car to take advantage of the taller gearing (lag notwithstanding), but the 3.0 NA doesn't have that.

OTOH, you could possibly use the 930 with a 7:31 RnP instead of the 8:31 you have in there now. Someone else would have to chime in and verify if that's feasible.

I knew a guy with an SC who's first gear was out and he started out in second for years until he sold the car, with no obvious ill effects. He actually said he liked it better anyway. You are right 1st basically just gets you rolling and it's time for 2nd. Are there any serious downsides to starting out in second, presuming that you are not on an uphill grade?

Of course with the 7:31 every gear would be shorter.

serious downsides? probably not serious, but you would probably go through clutches a tad faster because you'd have to slip the initial gear more in second than first.

If it was in a 2000# car it'd probably be fine, but if it was a 2600# SC it would probably not be ideal. More weight would also mean more stress on the engine like when an engine is lugged.

Yes...that is not an option...I don't wish to sacrifice top end...I merely want to design a 'touring car' effect.....

I'm really surprised no one has attemted this in the past.....
