CVF does but dammit I forgot to look up the part numbers up for someone on here.
Unreal.
So my best memory is I used one pulley from a 440. Can’t remember if it’s the top or bottom pulley but it will get you to 6% over.
If I can find them I’d drive the pump 25% over.
Of course I’m shifting at 6500-6800 rpm. If I was turning it higher I’d slow it down a bit to keep the belt on.
But you can bet all you can afford to lose but I’d test the 25% over pulleys on the dyno and if it didn’t throw the belt at 7500 rpm I’d run the 25% over pulleys and not even worry.
Edit: I profusely apologize to the member that I promised to look up the part numbers for (that’s bad English so I apologize for that) but my dad got sick and I had to come to my parents place 3.5 hours away. I might not go home for several weeks depending on how it goes. So I apologize that I forgot to look them up.
