I found the rest of the supercharger to be very robust, never saw bad needle bearing in any of the jaguar 3.0 superchargers I've refurbished, I replace them if I take the supercharger apart. You will get new snout bearings especially the front snout bearing which is getting the belt side load. Since the labor is the same as just a coupler, I recommend that you get a rebuilt snout or a new (genuine) jaguar snout. From that experience i can tell you the isolator will most likely fix your noise and get you another 50k more miles, this is what I sell the most of. I've sold over 500 for the 5.0 superchargers, /itm/112433728322 note different size isolator. I've sold 215 isolators in the last 2 years for the 3.0 liter /itm/112433704125. From my experience your Isolator is Bad, I know its bad because you have the stock torsion spring isolator that goes bad in all the Jaguar / Land Rover supercharged vehicles starting at 50k miles. I can offer you some lower cost alternatives. SCOL is the absolute best, I have no hesitation in recommending them if you want them to check out your supercharger. Not sure if it can happen, but I wouldn't mind another 30HP if possible.Īnd here is Ed's reply - A knowledgable fellow: I have already done the VELOCITY AP crank pulley and tune, so it's pushing 450hp at the moment. There is also the other option which i am of course investigating - Quality superchargers has a "performance" pulley upgrade, which gets about 7% more power by changing out the Snout Pulley. that has new coupler, bearings, gasket, etc. Now i can also order a rebuilt snout from ebay for $400ish.
SUPERCHARGER ISOLATOR FULL
Then around $1600 to do a full rebuild with new vanes, etc. then $750 for the whole supercharger bearing overhaul. They quoted me around $4-500ish to do the coupler and snout bearings. They also said that these units are not rated past 125k, and that after 100k they would generally do a vane replacement and rebuild the unit including all bearings and "wearables." Which means that it may be worth my while to do those as well. Now the obvious question is given the PITA to take the snout of the S/C off, as detailed in that Jagforum post above, What else should be done while you are in there? Superchargersonline said that basically, the couplers go early, 40-75k a lot of times, and that around 100k miles the snout bearings will go too.


those springs break, and the solution for longevity is to replace the coupler with a solid unit, as shown above. It's made with springs to dampen vibration to/from the engine. Basically, the coupler is the part that fails. There are several routes to take on this project. And I spoke with Superchargers Online, a Simi Valley company that sells parts online, and also has a shop. I am talking with Ed, the "quality superchargers" guy on ebay.
SUPERCHARGER ISOLATOR UPDATE
*** *** FOR ALL INTERNATIONAL ORDERS, PLEASE CONTACT US TO DETERMINE YOUR SHIPPING COST.OK, brief update here. *** * ** ALL ORDERS MUST BE PRINTED OUT & PLACED IN THE BOX ALONG WITH THE SUPERCHARGER. *** IF YOU SELECT CORE, YOU WILL BE REFUNDED FOR THE CORE EXCHANGE ONCE WE HAVE RECEIVED YOURS & INSPECT IT TO MAKE SURE IT IS IN WORKING CONDITION. This allows the air to fill for more time & will discharge with less then 5 degrees of rotation allowing air to exit the rotor pack with out a drop in performance.

The blower portion of the inlet is modified past stock housing allowing more air to enter rotors using out rpm based port design. They are ported and built to push the LT4 to new levels. Race Port is for those looking to push their LT4 o the absolute maximum limits! Race port is for the RACE APPLICATIONS ONLY & carry NO WARRANTY. Our blower’s are cut on a Centroid 5 axis cnc and proven to gain up to of 60 hp and 40 ft lbs over a stock blower when selecting the full tilt supercharger port package. Consistency from blower to blower you know your going to get the same power every time.
