vortech 2.87 pulley not right
Here's the deal...
We made the 3.125 and the 3.33 thinner on the top and bottom end ribs for clearance issues on some of our Mustang systems. The 2.87 was never used in these systems, so we never changed these pulleys. If you want to use the 2.87 that we have, you will have to get the material on the top milled down. Or you could get a custom pulley made.
With all that said, it seems that there is a 2.87 on a car with no problems. Was there any modifications made to the pulley or the housing???

Booger,
When you purchaced the 2.87 dia pulley from Vortech, Did you tell them what application it was for (350z/G35)
If so they should have told you that it would need to be machined and that they would do it for a nominal price.
All that said........ All of Vortech 6 rib Driven Pulleys (same Family) should be of the same Design, if you change Design in ONE you should do it in all.

okay....
my findings.....
my 287 went on WITHOUT any machining whatsoever....
this "machining is a must" idea made no difference on my blower....
Boog- i think your jackshaft headbolts are stickin thru the bracket too far, and thas what rubbed..... make sure you have the washers on them ((non blower side))..
you might need to back em out a turn or two, or just add an additional washer to them. (YOU DO HAVE THE WASHERS ON EM, RIGHT)?
theres no clearance issues even close, other than that...... (by close i mean 5mm or so)
WTF would you be sold this part for, (i was told the 287 WOULD work fine) if it doesnt fit??
also, some pulleys coming with stamps on one side, the other side, no sides, and the newest:: no anodizing (makes me think theres other issues??)
i know the guys at V know their stuff, but wtf??
heres the 333 versus the 287

I give this information out to the best of my knowledge. I am not an engineer and I am not going to ask an engineer every time someone here has a question. I told you all what the issue was and how to fix it. Most of our pulleys are made the same, but these are different. If the problem ends up being with the pulleys and not the hardware on the jackshaft, then you can return the pulley for a refund. You guys are doing things that we haven't done or condone doing. This is new ground for us all, so please cut us some slack. Sorry for the rant, but I do all that I can to help you guys out.

steve--
im not bashin ya or tryin to give you a hard time. I have always been a fan and supporter of your products, but as for your last claim of " not condone doing", well, i had a phone conversation w/ you in regards to this pulley swap, and you definately told me it was okay.
Is it not, now??
i am concerned..........

As far as warranty goes, it's not OK. We sell these systems with a pulley size to our specs. Any smaller than that and we have to look away. Sure we will sell the parts, but we won't make any promises. For one thing, this is why we do not call the 3.125 pulley a "9 pound" pulley. It could produce that on these cars, but no promises.
Forced,
I agree with you that the harshness of some of the above posts are not helpful. Come on guys, lets play nice. I appreciate the contributions you make in this forum.
On the other hand, I definitely do believe that Vortech has some accountability here. Vortech has been in business a long time and as professionals, the company has an obligation to disseminate true and correct information because whatever you say IS going to be believed
If I tell a friend that I think he will save money on gas if he fills up with a half water, half gas mixture and he does it, then I have little responsibility if he screws up his car. I never claimed to be an expert. However, if my friend took his car into the dealership and they told him to do this, I think they would owe him a new engine.
I truly hope that Vortech will step up to the plate here and take responsibility for this unfortunate event. I am sure this has been very distressing for Booger, and he seems to be taking it in stride.

The car is not here right now so I cant check it . But Im sure it was not rubbing up against any of the bolts for the jackshaft assembly . Its rubbing against the assembly it self .And it scrapped the crap out of the jacksgaft assembly . Tomorrow I will take off the 3.12 pulley and take a pic . There has to be some thing different between my assembly and Esemes assembly or difference in pulleys . I would just like to find out why , so no one esle has to go through this . The pulleys look the same , so there must be some thing different in my assembly . ....Bill
The quote "this has been very distressing for Booger" made me chuckle. It's a $50 pulley, not a family tragedy.
I agree with Steve (Forced) on this one. Vortech has to walk a fine line here between letting us make these types of mod w/o necessarily sanctioning it. If they felt like 9, 10, or even 12 psi was completely totally safe for the stock compressor on the stock motor then they would ship the kit that way.

Its a $90 pulley shipped...but yes its just a car......lol......Im not to happy that my Jackshaft assembly is all chewed up but I dont think it hurt the bearings inside . It only took 5 seconds of running to chew up the outter edges of it . If you look at the pulley...it was damaged far less .

OK...My girl friend is back with the car . I went out and looked at it, to see what could be the possible differences between mine and esemes [Scotts] . There can only be 3 things . [1] The stem on my pulley is shorter [2] The inside diameter [ look at my damaged 2.87 pulley ] is smaller [3] The out side diameter of the jackshaft assembly is bigger . I measured the stems on the 3.33 and the 2.87 and they are exactly the same . So we are left with the other 2 . By looking at jackshaft with the 3.12 on it now , I would guess its the assembly it self that is larger . IMO....Bill
