Stock transmission paired with big motor

[jleavitt73]

Is my stock 74 Super Beetle transmission strong enough for a 1835cc engine? Basically, am I going to break things if I dump the clutch?

[Glenn]

I've broken a stock 74 tranny with a stock 1600.

Abuse it and it will break.

Remember, you're talking about a 43 year old transmission. Who knows it internal condition.

So basically do burn outs at your own risk

[modok]

Never dump the clutch. At least pre-load it.
If it hops then just don't do it.

If you want to impress morons put on some hard old snowtires on the rear

[jpaull]

Not just the transmission, but any wheel hop is gonna kill your nose cone and leave you stranded.

Beetles have a lot more drive wheel traction than RWD American cars. A 40 horse engine can destroy a stock transaxle if you insist on dumping the clutch.

If the trans is in good shape it will be fine as others have said don't dump the clutch from a stand still

[Pruneman99]

I say dump the clutch at will. The guys that build air-cooled transmissions need customers to stay in business and continue to supply us with quality rebuilt boxes.

[modok]

Yeah. do a burnout in reverse!

[kokanee]

[vw moses]

lots of mounts to help trans to be rigid, but if you have a stage 1 pressure plate i heard get a heavy duty throw out bearing shaft, stronger welds at the arms

Would likely have stalled in a forward gear. Weight shift thing, Modoc is correct.

My Rabbit would do burnouts all day in 1st or 2nd but would just smoke the clutch in reverse. Weight shift thing!

You people are funny. that iddy biddy 1835cc will not crash that box w/ stock clutch. If you put a puck clutch in there will split that input shaft in half.

That 1600cc must have 1200 horses to break a stock trans.

Burnouts, huh?

[modok]

Drag the clutch a little bit, to take all the slack out if the drive train, before releasing it all the way.
If you "need" to keep the car from rolling forward at all...
Hold the car from rolling using the e-brake.
Release the clutch and e-brake, and mash the go-pedal at the same time.

I made my e-brake work backward, you push the button to lock it.
Unfortunately, it still confuses me now and then. Outsmarted myself apparently. Few more years of training maybe I'll learn.
Would be safer to just have it not lock at all.

[vw moses]

building a 2332 screamer(51mm carb.45x37.5 valves,1 7/8 exhaust) gonna keep the 63 swing arm trans. that came w/vw i'm not gonna dog it, but will wind it out! see what happens, going to put heavy duty thro-out shaft, got a kennedy stage 1
