Pulley - Mina or Eurotoys?
#21
Not to add fuel to the fire, but I figured I would do a search on the cobra forums to hear more opinions. This really does not add any value, but at least you get to hear more perspectives and opinions.

I work for a big aerospace company, so I will ask the aero engineers tomorrow what they their thoughts are. I am sure they will want to know they exact material because there are different grades of Al or Steel. Either way it will be nice to hear a technical opinion.

Regarding the steel pulley: The install instructions warn to be sure you place the steel pulley eactly on the shaft to ensure proper alignment with the pulley's ribs with that of the belt drive pulley's, not doing so may necessitate high heat to expand the pulley for removal then proper placement. High heat can damage the blower snout. This is not the case with the aluminum pulley. Anyone who claims the aluminum pully can slip likely has been sucking on the outlet end of a NO2 nozzle. Unlike other manufacturers who use superchargers with keyed shafts, Jag specifically uses non-keyed shafts due to the extreme super tight clearance of the shaft to pulley equation. Furthermore, there is absolutely no room for dissimilar metal electrolysis to occur. My aluminum 1.5 Mina pulley showed absolutely no sign of electrolysis nor slippage during its nearly one year tenure.

Love it; I was in need of some humor Tuesday morning!

fergs03R, vance580 hit the nail on the head. If you're good with a cutter then you'll save a bunch of time (no jacking engine, etc.) Slice the stock pulley in fourths without cutting into the s/c shaft. The pulleys tension on the shaft should ease (Whoa! Trying to keep it clean here.), then nudge it off. The re-install is much easier, especially that the 1.5 Mina pulley is aluminum.

What helped me for the install too was a long 2x4 up against the pulley with a buddy holding it then get back at the other end of the 2x4 and hit it with a BFH to press the pulley on that way you have more room to swing and you wont knick up the pulley. Just make you tap it on and its straight before you go to this. It make it going on a lot better since I had more swinging room.

Not to mention my issues with euro toys and mike providing incorrect lower land rover pulley for a jaguar that pushed seal into chain and resulted in all the valves bent on a bank. I feel bad cause I should have caught this and Mike has agreed to help with repairs for their part in this. As I have said, everyone makes mistakes but its how theyre handled when they happen that makes the differance. This is unfortunate as someone with a Jaguar probobly kept their stoker and just got a 4.2l balancer from a junk yard and sent back to Eurotoys for core screwing everyone in the process. Land Rover and Jaguar 4.2's balancers are differant in many areas, this being one even though they look the same at first glance. I have recommended Mike for years and this was a bumpy first time mistake. Its been handled now and everyone is satisfied with the resolve and I apprieciate the great customer service and comminucation to resolve the issue. Makes for a great company...
