I'm pretty sure I used the stock bolt with my Speedmaster. I did need a longer one to start pulling it on.... Or did I drive it on with a hammer and wood block? Don't remember for sure. But the stock bolt is what I ended up with.

 

Bolt problem solved. It turns out the bolt fits much better if you pull the harmonic balancer bolt out of your pocket and use it instead of waiting until you hear it banging around in the washing machine hours later after trying to make a much smaller bolt fit in the crank. Sometimes I make it so difficult!

 

Haha! "Sandblasting" the inside of the washer?? Glad you figured it out

 

Still working fine? Thinking of picking one of these up.

 

Just finished reading this thread and have to comment on post #21 by bmdouble. I've been using a PRW damper for at least 3-4 years, running it to 7k redline repeatedly (Thanks to Way's tune!) with no issues whatsoever. Had I received a defective unit, I would've contacted PRW for a replacement.

 

Yeah Hobine, the Speedmaster is still working fine. This is my wife's daily driver and our trip car, so it probably has 25k miles on it now.

 

PRW installed here. None of the wobble that was mentioned earlier. Heated in oven for 30 min at 275, went right on the shaft.

 

Buy once....cry once. Buy the ATI and be done with it

 

Just installed PRW, no low RPM wobbles, slipped right on after heating for 30 min at 275 deg F.

 

Hi GearheadS now it is more than 10 years, how is that Speedmaster doing?

 

Hi GearheadS
I am thinking to get the Speedmaster crank Pulley, so just wondering if still doing awesome?

 

Sorry for the delay... Yes, haven't touched it since! Lots of miles on it.
