    Question: Rear Main Seal info for 87 B2K

    You would need to fix the switch and/or any relays that may be faulty. In the chip you can set the parameters for automatic OD engagement, or prevent it from engaging automatically alltogether. On mine, OD only engages when I press the button (still in gears 2-4) and automatically disengages...

    Question: Rear Main Seal info for 87 B2K

    I'm surprised your OD isn't already manual-only operation. In my Callaway supplement to the owner's manual for '87, it says that the auto-engage logic for OD has been disabled in the chip. I've read my chip out and verified that this is true (essentially set to auto-engage at 255mph or...

    WTB Dymag Gen II Wheels

    I believe Lee G. (the guy you got 4 gen 1's from recently) has an extra set. Are you looking for ZR-1 or GS?

    Value of Dymag wheels

    If they need refinishing, about $1200-$1500 a set - $1500-$2000 if they're ready to go. A set went for $1k at this year's carlisle. A set went without bids on ebay recently for $1800 and sold off auction for somewhere north of $1500. That should give you some idea. I am interested if you...

    Choose your weapon: Electronic countermeasures - what is in your arsenal?

    Cross, I don't think this thing's all that powerful. My understanding is that it's weaker than a normal radar gun but powerful enough to send confusing "reflections" that cause the radar gun to calculate an oscillating speed (and read blank since it's looking for a steady speed). It has a...

    Choose your weapon: Electronic countermeasures - what is in your arsenal?

    Oh, I've been hauled in down in Hazzard County before, but that's a whole different story!

    Choose your weapon: Electronic countermeasures - what is in your arsenal?

    You haven't seen the "vehicle radar cloaking device" (VRCD) by stealth technologies. It worked so well the FCC shut them down! I have one and tested it by going by one of those "your speed is..." radar trailer signs. It's pretty cool as you approach and it's registering speeds of people in...

    Being draw in by the callaway..

    Callaway C4's came in 2 series, the '87-'91 RPO B2K twin-turbos and the '91-'96? supernaturals. The supernaturals were LT1 (except for a few ZR1's) based and did not use forced induction, just stroked with improvements to breathing. The twin-turbos have more power potential. The used stock...

    Help! Lean Condition, Need Help

    My finger's still pointing to the microfueler or it's vac feed, and here's why. The calibration in the stock computer's prom will not change by itself. When the prom goes, it will usually lose a few bits, and this will throw off the checksum, which will put the car in limp mode and throw error...

    Help! Lean Condition, Need Help

    Since you have a '90, you don't have a MAF (it would be pegged anyway if you did). As Surf has probably already told you, your problem is probably related to the Callaway Mircofueler system (drives the extra 2 injectors). Unfortunately, it's not adjustable for specific RPM ranges (just fuel x...

    713 rwhp 1990 Callaway Twin Turbo - I'm back with new numbers!

    All I can say is incredible - what would that be over 800 at the crank? I live up in Seattle and would love to see that beast sometime. It'll be the motivation I need to get my project going!

    Newbie Questions

    Welcome to Callaway ownership and the forum - you're gonna love it. Now let's see some pics!! For the tires, I'd go with the ones you listed. There are only a few choices left in the 255/50/16 size (Falken is the other that comes to mind, but I know a few people who have them and say they...

    If anyone is seriously interested in this car, I'd be happy to run down and check it out for you (not a full PPI, just another set of eyes). Your only risk is that I may talk Steve out of selling it! :L Tom
