Hi, is there somebody who knows what this gearbox is made from and what power it can handle?



Thanks

GARETH T

nto sure mate,,,, but i wouldnt mind it

Bart

These are the ratios:
Gear ratios
1. 1/ 2.70
2. 1/1.95
3 1/160
4. 1/1.25
5. 1/1.1

Would this be suitable for a road - 1/4mile sprint car?

GARETH T

very low geared,, is it a quaife? how much?

Bart

I don't know what it is. It should be a dogbox used in rallycross.
That car had 'only' 380BHP and 550Nm and the box had never problems with that power.
My engine is 500+BHP so I don't know if it is suitable.
Price is only 2800 euros.

GARETH T

you would hit top very fast i would think mate

Jim Galbally

1.1:1 in 5th? it'll do about 120mph flat out

GARETH T

but how fast will it get there

ian sibbert

do you have a pic of the cradle and lever? and a better view of the syncros...it dont look like a quaife centre case but its hard to tell...

Bart

No, this are the only pictures i have.
Is there much difference in the gears shown on the pictures compared to standard gears?

is the gear selection for 1st gear on a dog leg ?

looking at them gears i would say its a quaife, looks cheap, brass selector forks, narrow teeth pitch

ane even though the car it cam from only had 300ish horse i would like to bet you dont have anywhere near its 550nm of torque on a 500 horse engine ?

gareth it's get there quicker if you werent changing gear every 3 seconds

550NM is 405lbs-ft - easily achievable for a 500bhp engine I'd have thought.

not all the ones ive seen ! the majority of the so called 500 horse conversions struggle to make 380ft/lb

GARETH T

gear changes dont take long in a dog box though

Bart

I have some more information, the gears are made by a company called BROCEK. I never heard of them, they also make spare parts.
My engine made 492BHP and 540Nm @ 1.8 bar boost so with more boost it should get over 550Nm.

sounds like you got a good motor there pal never heard of that make of gears tho mate

Bart

I think I'm going for a FIXIT gearkit or if someone else can tell me more about this gearbox please let me know.

cossiemanden

My old engine made 394bhp and 507nm at 4400rpm so it´s possible to get that kind of torque

I own a fixit gearbox, and are WERY pleased with it

POPEYE

quick pic of your 3dr again bart. my second car 3dr out there
