Please explain the differences in the G50 box

[bubbles]

I am new to this Ultima stuff and need clarification on the various G50 boxes.

1)I am told there are long and short, but the chassis accomodates both. What are the differences, is the long box better for cooling the oil, as bigger, or does the long box take the 6 gears and the short the 5 gears?

2)What I am looking for is a box that gives good acceleration in all gears. I am not interested in 200mph, but really topping out around 150-160mph, as this is mainly useful for uk roads and short blasts. I prefer low down speed, low down generally to 120mph, so is a 6 speeder better for and not use the other top two gears or a 5 speeder with low gearing. My friend has a Diablo, so roughly the same power output, around the 600bhp figure, but obviously heavier, he rarely uses first and generally won`t drop below 3rd unless in slow moving traffic.

3)There has been a lot of talk about changing the gear ratios, but is this needed for road use, I understand for track use, you want it suited to the track.

4)Which box keeps the driveshafts as straight as possible, so no chance of snapping driveshafts, as they maybe at a different angle?

5)Are the long boxes used for the higher bhp engines as stronger or what. Sorry to ask so many questions in one hit, but I need to understand, so I don`t opt for the wrong box?

Any advice greatly appreciated.

Stig,

Excellent response, you certainly know ya stuff. The G50/02 as you have, if I am correct, would suit my driving requirements, i.e. more urge lower down and good pull throughout all gears right up to the limit. By the way, are rev limiters on these engines?

I remember seeing some graph, but can`t find it, where you can move your cursor across it and it shows the speeds, revs, bhp, any clues where it is?

Maybe we can talk more about this on Saturday when I pop over.

Cheers for the info

Whoops!! Forgotto say that I`m sure it was Ted at the factory who said that a lower geared car, gave the equivalent of another 50bhp, as I`m looking at one of the Amerspeed engines around 500-540bhp, this will put mine equivalent to mid to high 500`s bhp and christ, it takes yours to high 600`s.

Scary stuff eh??

Just found the link, but all three graphs are the 6 speed boxes, so no use to me.

BigMack,

Thinking the G50/02, same as Stigs, as he states it is the short ratio box, so although not good for the 160mph plus speeds, can`t see myself getting there that often, so not needed for me, but low down torque/pull/accelleration is immportant to me.

So if you have the graphs e.t.c. for this, could you post them or e-mail them direct to me, but best to put on here for others to see as well please.

Used to have a Lotus Esprit V8-GT and have hit the limiter 3 times in 5th, i.e. 175-180mph, but very impractical for uk roads and I must point out was on a motorway at 4.30am in the morning, nothing about, knew the stretch of road, M3, junctions 5 to 4, a straight 2 mile run, no coppers and no cars, only me to blame if something went wrong!! so I can`t personally see the point of a box that will get me to 180-200mph, when all I will do is quite often the 120-130mph and occasionally the 150mph plus figures.

I have certain runs I go on, know the roads like the back of my hand, all low down stuff sub 120mph, but a real adrenalin rush and there are a group of bikers who also do the run most weekends and it is good fun!!
