7 - 8 lb S/C Pulley
 

Since I have swapped at j35a3 in my CL last year after I blew my j32a2 with the supercharger I am looking to get the 7 - 8 lb pulley but I am having a hard time finding the part number for it so I can purchase it. I have the high boost pulley on the supercharger now which produced 4.5 - 5 lbs with the j32a2. Correct me if I'm wrong but with that same pulley isn't it going to be a little less boost on the bigger displacement j35a3? That's why I want to get a 7 - 8 lb pulley.

Here is a 4 rib 3.12" pulley I found for you back in Jan2017 from summit racing when you were asking a similar question:

https://www.summitracing.com/parts/vor-2a034-312

Then Marcelechka chimed in with the comment below recommending a 3.2" pulley based on his personal experience.


You can find this pulley/PSI 'discussion' on page 6, starting with post #204 on your thread below:

It should help refresh your memory and help you decide. It just might turn out to be a 'grand experiment', in regards to which size to get for the PSI you are looking for because of the added displacement of the J35A3 vs a J32A2..

Hopefully, Karanx7 with chime in with the pulley configuration he is running with his M60 on a J35A3. :dunno: :) :thumbsup:

Thank you Zeta! Yes, I remember that I had talked about this subject awhile ago. My hbp is 3.33" (stamped right on the s/c Pulley) and my alternator pulley is 3". I think I'm going to purchase the one you mentioned (3.12"), only because I don't think that S/C can support much more than that. Also don't want to blow it up again. Lol
On a different note, has anyone had any luck with the AEM EMS 30-6051 working with the manual harness? Researching online all I've found was that boomslang makes a jumper harness that works but has some issues with certain things.

I used Pulley Boys Comptech 4 Groove Keyed Pulley 3.2" diameter. I was just tuned last month, we saw 8lbs on the dyno with that pulley.

Here's the link:

Nice find on the pulleys bluedc2.

And that schematic looks to have the information 2ndgentl needs to get his AEM EMS 30-6051 up and running. :wish:
Very informative post. :thumbsup:

Holy shit Bluedc2!!! Thanks a lot for passing all that info, very much appreciated!!! Are you running a J32 or J35, because 8 lbs of psi is around where I'd like to be. Also, what kind of power were you making at 8 psi?

Thank you Chris! 320 hp and 290 tq @ 7psi with a slipping clutch isn't bad at all!! Sucks that you have to do a clutch job real soon though. Do you have a clutch in mind that you're going to use? Also, are you running the stock flywheel or aluminum? I need to hurry up and just get my car dyno'd now so I can have a before and after the S/C results. - Joe

Just to clarify, Chris, are you utilizing:

the 'Base 3.0" alternator pulley'

OR

the 'High Boost 3.275" alternator pulley'

To get to the 7-8psi with the pulley boy 3.2" S/C'er shaft pulley? :)

I'm thinking you have the 'base alt. 3.0" pulley because Marcelechka claims he achieved 10-12psi with a 3.2' S/C'er pulley using the HBP Alt. 3.275" pulley noted above without the FMI.

I wonder if I should either get the 3.0" or the 3.12" since I have a J35. Im thinking the 3.12" will give me 7-8 psi?

Damn, sounds like you've had a lot of sleepless nights with that CL, but glad you moved forward with it and got everything resolved! I love seeing people still interested in these CL's after knowing there's hundreds of other cars out there to choose from. That must of been hard to see your engine blow as it was getting dyno tuned...

I had the HBP (3.33") on my j32a2 and it was producing 5 lbs of boost. Ended up blowing my engine (didn't get it tuned soon enough). I went through two j32a2 engines from the junkyard and both were bad (one had a cracked block, and the other had low compression). That is why I ended up with a j35a3. Did you purchase your jumper harness through boomslang or Dezod? I just want to make sure I get the same setup as yours. I can't wait to hear that whine again...

All the Dezod kit is a AEM box switched to hall sensors and the Boomslang harness.

Dam, that sounds like a nightmare. I'm sitting here thinking why would the previous owner think that a 'timing belt drive pulley with reluctor' from an automatic engine, either J35 or J32, would have worked on a manual transmission CL-S configuration. :ugh: The part numbers for the automatic '02 J35 TB drive pulley' is the same as the automatic '01-03 J32 TB drive pulley'. So, that means you / your mechanic had to hunt down the cause, the wrong TB drive pulley, and then purchase the correct one to eliminate the CEL.:whyme: By that time, unbeknownst to you, the engine may have already been damaged, in some way, to cause it to 'grenade' on the dyno after being fixed with the proper 6-speed TB drive pulley.

Just an FYI, Chris. You may already know this or have it already installed on your car. There is a Mugen fan switch and low temp thermostat modification that turns on the fans sooner to get things cooler. From what I understand, with this mod, you don't 'gain' any power per se; however, it keeps you from 'loosing power' when stopped or in slow moving traffic. :shrug: It will affect the cabin heat function, slightly, in colder climes, so be aware. The part numbers are below IF you don't already have them installed and are interested:

THERMOSTAT 19301-XGMR-0000
FAN SWITCH 37760-XK5-00N0
RADIATOR CAP 19045-XGER-0000

Furthermore, if you or Joe need to replace or upgrade your OEM radiator to an aluminum one there are options which are discussed on the thread below:

:thumbsup:

Thanks Zeta, for the information on the Mugen fan switch mod. I will look into that. My tuner is wanting me to go meth injection once the summer heat hits. When it was on the dyno 3 weeks ago the highest intake temps we saw were about 98 degrees which is pretty good. The CL isn't my daily driver, its more of a weekend warrior for me. It sits in the garage usually 6 days out of the week.

Is this the kit I need? Also, I already have the AEM EMS SERIES 2 30-6051, do I let the tuner switch the box to hall sensors or is that as easy as it sounds? I see a smaller box attached to your green harness, not sure what that is. Sorry for all the questions, but things that really interest me is like my caffeine in the morning. I get excited when I learn new things. Lol

Not sure what I'm looking at in the red circle:

Thanks for reminding me Zeta about those items. I had all those parts (except the aluminum radiator) on my j32a2 but can't seem to find them after the j35 swap (I think I may have left the stat and switch on the first engine I bought from the junkyard that had the crack in the block). I am putting these items on my Christmas list along with the aluminum radiator!

^^
That's the 'Connector A' 'Connector B' 'Connector E' box diagram illustrated in the middle of the schematic supplied by Chris in post #6 above.

Wow Chris, the 4th one you've owned! That's awesome! Every time I run across a clean 03 6-speed CL-S on Craigslist or FB Market I always have drawbacks whether I should buy it or not. Then I think to myself "what the hell are you doing...." Lol But for the price these cars are going for it's kind of hard not to want one. I really can't think of another car as nice/quick/reliable/sporty/luxurious/and different as these cars that you can buy for under $5k

2ndgentl, this is what I would do:
1) make a copy of the schematic Chris provided in post #6
2) contact Boomslang directly and talk to them about making you a 'harness' compatible to the AEM 30-6051 to 2001-2003 Acura CL MT based on the schematic provided.
3) cross your fingers and toes that they agree; otherwise, they may not agree because that 'harness' may be proprietary to Dezod :(

Thanks Zeta, I will contact them this week and cross all fingers and toes. Worse case scenario I will contact Dezod (I have him on my FB messenger and had talked to him before) and ask him if he could make me that harness.

Keep in mind, worse worse scenario.

If Dezod refuses to make ONLY the harness for you, for whatever reason. Technically, since you have the schematic, if you can source all the appropriate connectors, wiring and the box the CL harness connects into, you could make one yourself. Sourcing that 'stuff' online should not be that hard and readily available. You will have to follow the schematic and 'pin' the wires to their appropriate connector location. It will just take time and patience. Then of course, there is the matter of switching the AEM EMS 30-6051 box to hall sensors, which should not be to difficult, although opening the box will probably void any warranty. :shrug:

Good Luck!

Nice Chris.:)

Wow Chris, a million thanks! I feel like you have held my hand guiding me through the light. Lol Should I just personally message him and go from there? I wonder if I should also ask him how to switch the AEM box to hall sensors

2ndgentl, if you find out how to do this, on your AEM EMS 30-6051 unit, make sure to take plenty of pictures and show us what exactly you did. It would be a first here on the forum. :thumbsup:

Most definitely Zeta! I will be sure to take pics of everything I do that I think would be helpful to others. I also have a neighbor across the street from me that races his car at Sebring, Florida. The guy reminds me of the "Rain Man" but in tuning/building race cars from scratch. The guy has been doing his own work ( fabricating, tuning, ect. ) for over 40 years. He races a 93 body style RX7 which the car looks like it's on steroids and there is absolutely nothing stock on this car, including the frame, body, suspension, ect. Where I'm going with this is that he is very helpful on helping me out with any questions I have about my car. I'll see if I can find any pics of his car later. I messaged Dezod (Chris) and now waiting for his response. I don't expect him to respond me on a Sunday, but I'll post a pic of our conversation afterwards
