Default Top speed for stock 89

Can someone tell me what the top speed should be approx for a relatively stock 89 (see mods). Does anyone know how much if any having the top up/down makes in top speed. The other day i went out for a pleasure cruise-top down. Not planning on going fast, but ended up on a very deserted long straight road, no wind. It felt so good that i topped it out at 133. Is that about avg or should it be higher?

They should top out at about 150 or so.... You need the top up to get there though

I believe youll need the top up, and somewhere between 150-160 is tops
