hey, was wondering if a stock 4.125 t1 box could handle an atmo 12a carby motor.

these were about 112hp when NEW.

so say a used one makes about 100hp.

probably. but no box will last if you dump the clutch at 10,000rpm all the time

Absolutely. SSP box should be fine for that power level - there are plenty of NA VW motors around making more than that running stock SSP boxes.

Like any pobjoy steroid engined car - they are ~ 120hp or so.

my current box isnt the single side plate box with the 3.88r&p. mine is the 4.125 box with dual plates.

Power doesn't break things, torque does. An atmo 12A doesn't have a lot of torque compared to it's turbo counterparts, and is probably comporable to a reasonably worked 1600-1800cc VW motor, so I'd say it'd be fine as long as you don't abuse it.

Well, that and I have seen some 12A VW's getting around on the single sideplate boxes with apparently no issues.
If it aint broke,
Make it go faster!!
