DMPE did my B&M 174 blowers , must have 180 hours on them now. I did have one first day out started making a weird noise, shut down and removed belt, teflon strips where touching, DMPE requested both Blowers removed and sent for a ride back to DMPE and they fixed the problem and returned. timeing issue!. Like i stated before, 180 hours on them now with no issues. They stand behind there work.

Just got off the phone with Bryan. He spent some time with me explaining what he will do do for the inspection. He also told me that they have been working on a replacement blower for the 256 that will use the same manifold and setup. he did not give me a time frame but after he gets my cratered blower I'll start pushing to be a guenui pig.

It's a shame to hear what happened to a brand new blower rebuild on such a low hour motor. But, it does sound like he's willing to work with you, that's awesome.
I'm curious did you pull the heads and check the cylinder walls?
I couldn't tell by the pic's.
I know another member posted a blower pro said it usually doesn't cause any cylinder wall damage, even so it's well worth popping them off for a visual inside the bores and a peek at the valves and it's angle cuts in the head.
I hope they work it out with you promptly.
See ya,
Kelly
Disregard my question about pulling the heads, after reading the whole thread I replied and then went back and looked at the pic's and reread your original post. Just a case of brain fade after getting on the computer after working for 10 hours outdoors in the SE Texas hotass summer sun.

Sent my 256 Weiand blowers off my 575’s to be rebuilt. After reading how weak these rear brgs are I wanted to be pro active. The engines had 122hours on them. I had them Hard Anodize the Rotors, Hard Coat Interior Case Bore, Add Teflon Stripping, replace all brgs.. When I received them back one of the blowers were put together backwards. They sent me a fedex label and had it fixed and returned in 3 days. Very happy with the performance of the engines after the blower rebuild. Picked up almost 2 pounds of boast and 5 mph. Long story short one of the blowers seized up at the Outlaw challenge poker Run. Boat run great on Friday with no problems. Sat after the first stop took off and cruising around 4000rpm’s when I felt a vibration and I throttle back and the port motor died. Pulled blower belt and blower was seized. The rebuilder says that it must have backfired or had other engine failure for it to happen. I video the tear down and there were no missing bolts or nuts from the injectors or housing. I pulled the heads to make sure there was no other damage and everything looks great. There was a chunk of the rotor in #3 but no damage. I think a bearing went south in the blower and caused the rotors to touch. This also was the blower that was put together backwards and sent back for correction. After talking to him and sending photos and videos of the teardown ,It seems like he is not going to stand behind his rebuilds as he said that they do not make rotors any more for the 256 and I will have to buy a new blower. I’m at a loss on how to move forward. If I sent it back he can’t fix it. Need advise please.

Wanted to update everyone on the outcome of this. I sent the damaged blower to DMPE and Bryan took it apart for inspection. Found that the washer that holds the gears to the rotors had cracked and split letting the bolt back off and causing all the damage. He said that these washers need to be replaced every time the bolt is taken out as they crack when retorqued. He had me take apart the other blower and check to see if the washer had been replaced. Well sure enough it had not and you can even see it starting to crack. Well long story short the company (SUPERCHARGERS USA) would not stand behind their work. I did a charge back on the Credit Card but he is fighting it to the bitter end. I ended up spending a lot more money because of Superchargers USA not doing a complete rebuild and taking short cuts. I ended replacing both superchargers with Dyers Superchargers.
