whats the max you can run on a 2.3 whipple II gen? 2.75 with 4lb lower?
I bought Ricky's blower.
For anyone thinking that it's "strange" that I just now am having issues with the blower, it's because I didn't install it immediately after receiving it. I accumulated supporting mods slowly and made sure all my bases were covered before installing it. I'm not made of money.
The blower was installed correctly, everything hooked up properly, verified by my tuner. The moment I fired the car up is when this noise developed. I am not saying or even implying that this was something Ricky did maliciously whatsoever, it's just what happened. Whether it be from shipping or what, the problem exists regardless. I understand buying used is a buyer beware situation, and I am not questioning Ricky's integrity at all. He helped me get a hold of everything I needed to get the blower installed.
I'm still trying to figure out what to do with the blower, that's why I haven't been in contact with Ricky since this occured. The price tag from Whipple for a rebuild isn't really friendly, so money is an issue for me. I'm doing what I can to get the situation figured out on my own.
I would have a hard time believing an active member would knowingly sell a bad blower to another board member. The repercussions from doing that kind of thing are pretty severe around here. I can imagine your disappointment. Let me throw a few things out which may help you isolate the problem.
I imagine there was sufficient oil in the blower cases before you started the engine. True statement?
Did you change the oil?
When you inspected the blower did you see scratches on the rotors or inside walls?
Any visible damage to the outside of the blower cases or pulley?
How was it packed when it was shipped? (Don't overlook shipping damage especially with something so heavy) Did the shipping container show any signs of being dropped? The box getting dropped or even shipped "pulley side down" could damage the drive bearing. If was just shipping using "peanuts" that is not good. Imagine the weight of the blower working it's way to the bottom of the box when it comes to rest on the pulley. On a cross country trip riding in the back of a bumpy truck with 4 days worth of constant hammering could take it's toll.
Turning the drive pulley by hand. Is there even the slightest resistance, binding, rough metal siding action?
Describe the noise in detail. Is it so loud you want to shut the engine off immediately?, how long did you run it for, did it get any quieter as it got warm? It will be hard to distinguish the sound between a bad helical gear and a bad bearing but chances are its a bad bearing.
Funny as this may sound, sometimes small shards of metal may settle in the bottom of the oil sump and sit there. When the blower is turned over the metal can find its way into the drive snout where it can get caught in the bearings. Remember that 4 day trip and all the shaking the blower was subjected to.
Worst comes to worse you open up the front case and look for signs of damage. Make sure the wear marks on the gear mesh are centered and even. wiggle bearings, check races and move shafts "in & out", inspect the case and rotor seal surface.
Hope this helps.
