felicia gear ratio's

[TeflonTom]

has anybody out there got a list of all the gear ratio's that are available for the felicia gearboxes.. i'm planning some gearbox surgery in the near future

thanks in advance

[skorob2007]

According to a 1996/7 Press release I have, the ratios for the 1.3 54hp and 68hp models are:
1st :3.308
2nd:1.913
3rd :1.267
4th :0.927
5th :0.717
Rev :2.923
Final drive:4.118.

1.6 models:
1st:3.308
2nd:1.913
3rd:1.267
4th:0.927
5th:0.795
Rev:2.923
Final Drive: 3.350


1.9D models:
as 1.6 1st - 3rd
4th:0.975
5th:0.795
Rev:2.923
Final Drive:3.833

[TeflonTom]

thanks very much, that is looking very promising, i feel a trip to the skoda dealer coming on

[pinkskud]

tom are you thinking oilburner box on your 1.6?????

cuz i am.

[TeflonTom]

no, i was thinking using a 1300 box with 4.11:1 final drive and using the fifth gear from a 1.6....

the 1.3 and 1.6 gearboxes are largely the same, the only real differences are the mounting plate on the end, and the clutch levers are slightly different... and of course the 1300 box has a hole for the hall sender... so it should be an easy swap

[Mr Butter]

I thought the diesel boxes were supposed to be a weak point? Whats wrong with them?

Tom, just to see if I get the jist, you want to lower your gearing, but keep a high 5th for cruising?

For general interest, if a diesel box pops, whats the best option for replacement (they dont seem to be that common and are pricey, loads of 1.3's around though)

[pinkskud]

so let me get this right. its gunna be a 1.3 box, with a 1.9D 5th gear, and a 1.6 end plate/mount.

[TeflonTom]

yeah, and the bellhouse adaptor plate from a 1.6

also using the clutch lever, flywheel and clutch from a 1.6

[pinkskud]

i'm with ya, think i might look at doing that to soon. think i might have buggered the diff a little when i smashed the wheel off.

[TeflonTom]

i've done it ed, and i can confirm nothing needs to be swapped over on the gearbox to make it fit, the 1300 box is a direct fit on the 1600 engine, so long as you have the 1600 flywheel and clutch, and obviously the adaptor plate fitted still...


OMG what a difference, the car now feels noticeably faster, more lively and is generally more fun to drive now, i'm amazed how much difference it's made just changing gear ratios.... IMO it's probably the most cost effectgive modification you can make to a 1600 felicia, i paid £90 + vat for this gearbox from skospares in poole, and £46 for the new clutch... and it has increased the torque by approx 10% in every gear at every point in the rev range

How many revs is it doing at 70 tom

that's a good question

i'll have to check next time i take it out for a blast

[anewman]

Probably of little use but for reference the Haynes favorit manual says final drive
estate and pickup models 4.167:1
all other models 3.895:1

All other figures same as felicia 1.3. Got to say I haven't a clue what these figures mean but I assume the 4.167:1 means more pull.

[TeflonTom]

think of it like this....(i'm going to over simplify it a bit)

for example, your engine needs to do 5 revolutions to make the wheels turn once..

now if you change the gearing so that it needs to do 8 revolutions to make the wheels turn once, you dont need as much torque to turn them, but the engine needs to do more revs...

your engine is still making the same amount of torque, but now it is being mulitiplied by 8 instead of 5... hence more torque at the wheels

the downside is more noisey engine and the top speed may be lower

It can be noisier than it already is?

good skills tom. so did you swap you 5th gear over and put an oil burner 5th in?

[TeflonTom]

no i didn't. i worked out the the original 5th gear form the 1300 box was better anyway..
