• Failure to follow these rules may result in your threads being locked, deleted, or moved. Depending on the severity of your actions, or frequency of your actions, your user account could be suspended or banned. These rules are to help protect both buyer and seller.


    1. CONSOLIDATE all of your for sale items into ONE thread only. This means there will be NO making multiple sales threads for different items regardless if the parts are related or not.

    2. PRICE IS REQUIRED. We do not permit ads without an asking price for each item. "Best Offer" is not an allowable substitute for posting a price. You may ask for $1 but a price must be listed regardless. If a price is not listed with in the first 24 hours of making your sale thread IT WILL BE LOCKED or DELETED. Once a price is listed a bidding war is not permitted. If the seller gets an offer that meets his asking price, the seller should honor the asking price and sell for that amount.

    3. EBAY LINKS AND OTHER LINKS. We allow links to ebay ads, but you MUST have a buy-it-now price posted, or an asking price to stop the auction in your ad here (Not just in the link). If it is from another site or from here, do not use a link but post the full text instead with pictures if you have them listed. If a BIN price is not posted, then your thread will be DELETED.

    4. CITY / STATE are required info for each ad. Information must be posted in the first post of thread, NO EXCEPTIONS. Buyers and sellers reserve the rights to privately ask for full contact information on any purchase or sale. 24 hour notice will be given, if you do not comply your post will be DELETED.

    5. NO TWO PARTY SALES. This means no more "I'm selling for a friend" posts and will be deleted immediately with no notice. Seller assumes all responsibility of anything they post for sale.

    6. NO FEELER THREADS. You are either selling it or you aren’t selling it.

    7. POST COUNT AND/OR TIME LIMIT. We are requesting that you spend some time with us before you start a For Sale thread. A pre-determined minimum number of posts will be required or 1 year since creating the account + an intro thread (just so we know you aren’t the Prince of Africa). Any for sale thread posted out of the For Sale section to circumvent the rules will result in being deleted. Those who do meet the criteria and post outside the section will have their thread moved, constant violation of this will result in an infraction.

    8. NO BUMPING OR TT’ing YOUR THREAD MORE THAN ONCE IN 48 HOURS. Don’t worry your thread will still be a bold read until a user reads it and if people are really interested they will let you know. Post warning will be issued if in violation and on the 3rd warning, the thread will just be locked.

    9. NO THREAD DUMPING OR I DON’T LIKE YOUR PRICE. Don’t post in a person’s thread just to tell them they are too high, either move along and say nothing or throw an offer to them. The person can sell it at whatever price they think someone is willing to pay. Offenders will be issued a warning, if it is a constant issue then an infraction will be issued.

    10. KEEP YOUR THREAD UP TO DATE. This is really for your benefit, so you don’t get 10 PMs asking if you still have it when you already sold it.

    11. NO WEAPONS. As Admins we have determined that no weapons will be allowed to be sold, this includes knives, guns and anything else deemed a weapon (even if its a wall hanger only). We ask that if you want to sell these items you seek out the appropriate websites elsewhere to do so.

    12. Pictures are REQUIRED. Pictures of all items for sale. This is to help BOTH seller and buyer. As a seller it is MUCH easier to sell something if you have pictures of it. As a buyer you feel better seeing exactly what you are buying. Pictures should contain the item/s for sale and a sign of some kind that has your username on it. 24 hour notice will be given, if you do not comply your post will be DELETED.

    FRAUD & RISK. Buy and Sell at your own risk. Grand Prix Forums and its staff are not responsible if someone rips you off or doesn't send parts out in a timely manner. This classifieds section is a free service for the community, and it is YOUR responsibility to handle all transactions in a low-risk method. DO NOT contact us if there is a dispute between you and someone else, we are NOT INVOLVED. You can help minimize fraud risk by doing these suggestions:

    Pay using PAYPAL, using a credit card. This way, if a part does not arrive, you can do a charge back through your credit card company. If you gift it, then you have no recourse to get your money back when things fall through. Pay the 3% and have the buyer protection. Using someone else's paypal and gifting to pay for goods is violating Paypal's Terms of Service.



    Always ask for full name, residential address, phone numbers of both buyers and sellers. An honest seller should have no problem disclosing this info to you privately.


    Shipping things C.O.D. is risky. Try to use UPS or Fedex, so that you can track shipments. Have someone sign for it if it is expensive.


    Ask for references from other members, hopefully from other members who have been registered for longer than one year and are active here.


    Use your gut feeling. If something seems too good to be true, or a seller/buyer seems a little shady, don't take the risk.

    TIPS:
    -Post pictures: with mobile phones these days and auto uploads, it’s not even really hard anymore. Have it automatically drop in Photobucket, grab the Img tag link and paste it in.

    -Give good contact information if you aren’t going to be on here a lot.

    -If you are going to disappear for an extended time (vacation, time in jail, what have you), then give us a quick note that you aren’t going to be around. People will trust you a little more.

    -Look around and gauge your price with other items. Just cause you bought it for $1000, doesn’t mean it’s now worth $1,200 or even the original $1,000. You are free to ask what ever you want, but an item that is priced right will sell quicker.
  • The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Milled down a gen 5 LIM and supercharger. Extra 1/4 inch of clearance.
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

I thought this wasn't needed with the new core design.
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

New core is 2-1/4. Just playing around to see how much hood clearance I can get.

I don't think anyone has ever reduce supercharger and LIM thickness.
 


Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

OH! I actually didn't even realize you milled down the whole thing! SWEEET!

I was talking about the H bar.
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

i know many asked you the same question and i asked you many questions but i have read the 5 first page and here are my questions about the older version you wrote that you can fabricate the older version so i want the older because its 2 inch thick and for fiero Hood clearance i want this version .the questions is for the gen v ( older ic )
1. someone asked you if it can fit on a zzp machined lim and you said that the core size cannot have the pcv port but on the revised zzp can it fit and drill a hole for the pcv ?????? i asked that because i want a ported intake runner with my lim and i dont see that you made these lim with ported intake runner
2. can i use a garlock sc gasket and trim it to fit the ic you made or can i fabricate a gasket that will fit your ic with a zzp lim ????i know you recommend rtv sealant but want to try a gasket and will check for leaks ( i dont like rtv )
3. last questions if i can fit a zzp lim what is the version i will need revised or not ???? breather or not ?????? thanks a lot very confusing question i hope you will understand the questions thanks a lot
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

1). You can use on zzp manifold. Use gen 5 with gen 5 supercharger there rear hole may line up with my PCV rear hole. You will have to check it. There tiny groove will not work on my intercooler so you will have to connect front valve cover to TB yo get proper PCV.

2). I only recommend RTV! Don't wast your time!

3) use gen 5 lim with gen 5 supercharger for best air flow.
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Your work is really fascinating and cool. I am very interested in how that milled genv and lim turns out. Does everything still line up properly?

I am still trying to figure out a way to get a tiny bit more clearance with my SD hood. Currently it takes more force than i'd prefer to close it, and there are two spots on the supercharger that are hitting the hood and wearing down on both the charger and the hood. Debating on just grinding those spots down a little bit on the supercharger and then repainting I guess. I tried adding a few washers to the hood but that didn't help really, and I don't want to gain gaps on the outside.

I cant figure out why this phenolic stuff isn't used for more. I mean I could grill a steak on my genV with my SSIC and now I can leave my hand on it comfortably at any time. And I am loving having functional PCV.

If I understand phenolic correctly, it literally just has practically zero heat transfer properties right? Why not somehow apply this theory to the intake somehow. I mean one of the main reason cold air intakes are so ineffective on our cars is because even if you insulate the box significantly it still gets heated by the crossover as it makes it way to the throttle body and sc. Would it be theoretically possible to build like a phenolic box and some kind of phenolic tube that could go over the exisiting piping and throttle body or something? or even just some kind of blocker plate over the headers/crossover or something. I know you can wrap headers and ceramic coat them, but I have wrapped ceramic coated headers and it still doesn't make much difference.

Maybe those ideas are too complex for the properties of crafting phenolic material or just too expensive, but if it really does block heat that well it makes me wonder if it cant have vastly greater possibilities.

My intake temps (before supercharger), are always well over 100F with my mod level during daily driving and id like to find an alternative...
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Working on the Milled gen 5 install. Will have more info soon.

Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Are you still running the egr with your intercooler install?
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Is there any credence that running the egr with an intercooler will gum it up and not make it as effective to cool the air?
 
Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Yes. But PCV, EGR and just the intake air will also put some stuff on the heat exchanger.

I've had mine off a couple times and I didn't think it was excessive being on there for 3 years.

On the plus side the build up also builds on the rotors making the supercharger more efficient.
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Have you noticed any gains after you switched to the new style core?
 


Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

My new car is not modified to the extent as my old car. That said, the new bigger core has more cooling!
 
Re: Phenolic Intercooler Gen 3 Gen 5 L67 L32 Eaton M90 SuperCharger 3800

Will the notch for the larger alternator case clearance (post #461 and #462) be incorporated in the final design for the Gen V or will this need to be a special request?

All will be notched from now on.
