wut is synchromesh

[cyue005]

Hi guys

just wondernig wut da heck is synchromesh in gear boxes

 

[Oakley]

I think it for bringing the gear from the engine into synch with the gear to the wheels. The reverse doesnt have one thats why you have to let the engine revs go down to get in in!

 

[SteveJJH]

it speeds up the gear you are trying to get into to match the speed of the shaft/gear you are trying to connect it to. does that make sense?

 

[cyue005]

startin to haha wut if a gear box doesnt have synchromesh in its forward gears

 

[SteveJJH]

then you would have probably have to double de-clutch on your downshifts to speed the gear to the correct speed.

Then it would be like the very early cars...not too easy to drive

I used to have a Citroen AX and that didnt have a syncro-mesh on 1st gear.

cheesr guys understand now

oh yeh wuts the best method to dump the clutch for 0-60 test or quarter miles

do i keep constant rev n hold at grab point n just feed it in gradually? or do i do violent as dump

 

[viceroy]

as quick as possible so you dont get bogged down or loose too much traction is the best..try holding the revs at 3000, 3500

Depends what car youre in and where it produces maximum torque and power.

In a 172 youd have to go higher than that as it produces maximum torque at mid 5000s and 172bhp @ 6250rpm so if you dumped at 3000 it wouldnt be very good!

 

[SteveJJH]

but its probably still enough to spin the wheels

i have this demo on a S4 on friday u see wut i m sayin now? ahahhaha
