I am planning to have my B&M 177 blowers gone through over the winter and I checked with the blower shop and they said they arent doing repairs on anything but their blowers. What other companies have people used? TBS said they were sending people to Gerry Martin superchargers and I have found Jon Bond Performance as well as Dyers but I dont know if they are still in business. Any recommendations?

Always sent mine to DMPE

Don`t bother with Dyers, they never answer the door or the phone .. the son is running that place into the ground.
When i can`t get thru I stop by and they never open the door . Building is falling apart , maybe they out of business

Sent my Weiand 177's to DMPE.

DMPE, great guys there.
That's sad to hear that about Dyers.

Have them put the key way shafts in them so you have the option to use different upper pulleys.

thanks for the info. I will check into DMPE.
