Procharger Belt Issues? Here's a fix: AAM Supercharger Brace
The ATI Procharger supercharger was one of the earliest forced induction kits available for the Nissan 350Z and Infiniti G35. Over the last couple of years we've encountered a minor, but consistent, flaw in the design of the ATI Procharger unit. When the pulleys are upgraded, additional stress is placed on the superchargerís main bracket, causing it to flex. The angle of this flex causes the main belt to shift on the cog pulley under load. The end result of these actions is more rapid wear of the supercharger main belt, premature wear on the kits jackshaft assembly, and a loss of supercharger power and efficiency.
The AAM Competition Supercharger Flex Brace is the solution to this problem. Preliminary testing has show the AAM Comp Supercharger Flex Brace significantly reduces this flex and helps maintain belt longevity and supercharger power output. Constructed from the highest quality billet aluminum, the AAM Competition Supercharger Flex Brace can be used with Nissan 350Z and Infiniti G35 vehicles equipped with an ATI Procharger unit.
Note: A properly functioning jackshaft bearing greatly increases the effectiveness of the AAM Supercharger Brace. We will be working with Procharger to provide the best possible pricing for new jackshaft assemblies for those whose bearings have prematurely worn or those who have old units which are in need of fresh components.
AAM has already sent me two sets of bolts overnighted, (one set was the wrong length so im waiting on another set).. So I should be getting them tomorrow overnighted with instructions.. So far AAM has been really good with customer service and trying to make the mistake on bolts right...
How does AAM send you the wrong bolts twice? I mean, its cool they're helping you out, but it seems like they would already know what length bolts they need to send with the brace, yes?
LOL, very true. You guys can blame it on me. I ordered bolts for warehouse stock that were a little shorter than the ones we stock in the shop (which we use for install on the bracket) - I never noticed the difference until Jason pointed it out. And I forgot to add the 3/8-16 Hex Heads in the package
Everything is corrected and should be to you in no time! No more extra cash spent on belts, you should be romping on it by the weekend. Thanks for your patience Jason!!
I think these pics/thread combined with the AAM instructions will save other owners time and frustration..
Jason, Thanks for the input. I'm glad you got it on. I'll work on tidying up the instructions. I'm sure it will save you from a future of frustrating belt issues. As far as the 30 minute install time - well that's a bit of an exaggeration on my part. Coming from the guys who designed and installed the bracket countless times over the last four months, maybe - especially with some specialty tools (Mercedez Benz low profile allen ratchets, custom cnc tools etc - LOL, we have a habit of making our own tools). I tried the install myself this week and I agree, it is a serious PITA!! 2-3hrs minimum unless you've done it before. But the results are well worth the frustration ! Let me know if you ever need anything else.
Bro, I didnt even drive it.. After the install i was beat (combined with my daily job)..
I will give an impression today..
Thanks Clint, I know now that I have done it once I can do it again faster but I doubt 30 minutes.. I need some of those benz tools etc..
Personally I think removing the entire bracket to do everything is much easier, and doesn't take all too long. Really only thing you need to do is remove the serpentine belt, intake, and charge pipes (all cog belts can stay in place).
Custom tools definitely help out the job though, for example one I made specifically for Procharger setups:
Shitty pic, my camera sucks. Basically a 5/16" 1/4"-drive socket with an 8mm allen key epoxied into place. The allen key sticks out enough to perfectly bottom out in the main bracket bolts (with idler pulleys and spacers behind them). Break them loose with an allen key and a wrench, or a regular 8mm allen socket and a breaker bar, then switch to this with a 1/4" ratchet. The small ratchet and socket that's as small as possible allows for a lot more clearance between the ratchet and fan shroud, making everything a lot easier and quicker (also leads to less swearing). Although now that I think about it, cutting the socket in half would make it even smaller, and easier to get in there...hmm.
