    How to read turbo maps...

    There have been a couple of guys who wanted to know how to read a compressor map. Hopefully, I haven't made any mistakes this time (unlike the last) and this will prove to be useful to you in your understanding of a compressor map. Reading a turbo map isn't as difficult as it looks. The map displays 4 key pieces of information. A. It displays the pumping efficiency of the compressor (meaning the amount of actual air that it pumps in contrast to the amount of heat that's created while wasting e...

  • Cruise Control Switch Repair

    Cruise Control Switch Repair

    It seems that ALL the cruise control stalks you find at the JY nowadays are non-working. The Cruise switch doesn't work. Tired of paying $40 for a new stalk, I decided to dismantle and attempt repairs to what I had.

    The stalk is glued together and there will be some minor cosmetic damage during the dis-assembly, but if you file down the burs before gluing it back together it is not serious.

    This is the stalk I am going to repair.
    First, separate it at the join...

    V5 A/C compressor tear down / re-seal...

    Pictures of tear down and re-seal of Harrison V5 air conditioning compressor. These are very common on the 60V6 engines. They are very costly as a re-manufactured unit. The parts to re-seal them are about $30. I did this write-up for another forum but figured it would have interest here. I started with this unit. I had it on my 1972 Chevy Nova until it started leaking around the housing o-rings. It still cooled fine, it would just lose freon over about a 2 month period. It will go on a 2.8 car...

  • WOT-Tech pistons and the CR Calculator

    WOT-Tech pistons and the CR Calculator

    With all of the different top-end swaps and bottom-end builds out there, I was talking to Ben at WOT-Tech about the Diamond pistons and how different setups would affect the compression ratios (CR) of the pistons he was offering. I wanted to pass this piston information on to the users so that they could then determine what their final CR would be with any setup. Due to marginal sales, WOT-Tech has decided to no longer list or stock specific CR pistons anymore. What does this mean to everyone? It means you can tailor the pistons to suit your specific application, no matter what components you are using. ...

  • Cheap Strut Tower for 88-96 Grand Prix

    Cheap Strut Tower for 88-96 Grand Prix

    I found a cheap way to sure up the rear on 88 to 96 Grand Prix's. The front strut tower braces from 88-93 Cadillac De Ville will fit with slight mods. I think most of the full size gm cars from this time period have the same size brace. First take the ends off, it is two bolts for each side. I used a Dremel with a pack of cutting wheels from Walmart. I cut squares the length of the cutting wheels around the holes, meaning the size pre-use (they get smaller as you use them). Once you are done wi...

    How to Re-New Your Cracked Dashboard

    I searched the forum for any postings on this subject and drew a blank. Although this fix is related to any F-Body, I wanted to share it as a possible solution for anyone replacing their dried, crusty or shattered stock dashboard cover with a durable new cover and one that includes an inexpensive way to solve the lack of vent covers that most of these covers present with. Here is what you will need to do the job correctly and fast, too....: To avoid "a thousand words" that follow... here are th...

  • No Description of Part

    We're sorry, this part currently has no description to go along with it. We are working on trying to get as much information as available for each part as well can, but it will take some time.

  • Air Conditioning System Replacement Tips

    Air Conditioning System Replacement Tips

    This kind of repair involves more than just an R&R of a damaged compressor, since the old refrigerant must be removed from the system and stored in a proper container. Also... once the new compressor is installed, the system MUST have a near perfect vacuum established or the A/C will not ever cool properly. To avoid any woes (Whoas!) for your A/C repair, here are some suggestions for the fix that are "The Universal Baker's Dozen of Auto A/C Repair" : 1. Change the Accumulator at the same time t...

  • Testing and Cleaning your Digital EGR

    Testing and Cleaning your Digital EGR

    OK, now for a somewhat fun article: cleaning/testing your Exhaust Gas Recirculation valve, or EGR. Let's start with some engine theory. The EGR exists primarily to reduce NoX emissions by recirculating exhaust back into the intake system, where it displaces oxygen, one of the key components of combustion (thereby lowering the peak temps which prevents nitrogen and oxygen from combining). There are also a few other benefits that come from EGR usage; preventing burnt exhaust valves through lowering co...
