Nope, the ones I manufacture are 43mm in diameter. They provide a much lower drive ratio than the cheap, aluminum underdrive pulleys you commonly see on eBay. It's almost like the alternator and water pump aren't turning at all.
They're pretty impressive- barely larger than the crankshaft itself.

If I were to post pictures of my revolutionary invention, others would just steal the design and copy it.
You'll have to take my word for it that my pulley improves engine cooling while freeing up at least 10 BHP, improves the longevity of the oil pump gears, and triples your chances of scoring a date with Charlize Theron, all with no negative impact on alternator performance.
I can show you one of the early design concept sketches, though the finished product implements numerous improvements over this early drawing:
Real answer: Is there any one specific pulley you're inquiring about, or were you hoping that all aftermarket pulleys, regardless of who makes them, are of exactly the same dimensions?

So i don't have to explain please see my build thread. Space is at a premium and need to reduce the diameter of the pulley to make room for a steering rack.

You're getting trolled because your question makes no sense. You want to know the diameter of "an underdrive pulley" without specifying which pulley you're talking about, or what brand, or any other details that might help us answer your question. If you want a good answer, you have to ask a good question.

And, to be fair, we have some expressions in American english which are just as absurd. To quote the great philosopher Beavis: "How come they call it taking a dump when you're really leaving a dump? I mean, you're not really taking it anywhere... "
