  1. Driveshaft Shop Stub Axles

    Hey Racerteck, So are you running the same 35 count, 30 degree pressure angle splines on the outer stubs and flanges as well?

    Great Job! Bring it to Pacific sometime. Would love to check it out.
  3. Driveshaft Shop Stub Axles

    Most of them sell 930 "style" cv's. What they really are is VW bus cv's. The original German cv's used, will be better than new Chinese ones. I drag raced and sand duned for years with those joints and broke a LOT of parts. Never a bus CV. Off road racers prefer the 930 cv's because they will worker at steeper angles than the bus cv's.

    A part number for those bearings would be helpful.
  5. Z car IRS vs the NHRA

    I would agree that even real NHRA inspectors are very much on the honor system. I have been asked if I have a driveshaft loop, and saying yes was good enough. Even when they find something they don't like, they usually let you run, but ask you to change it for next time. But I have also seen where they will give you warnings about approaching a milestone ET and not being equipped for it. .
  6. Z car IRS vs the NHRA

    Way pro active. I'm just thinking about where I want to go with my racing. Right now I am in Sportsman. (12.00 and slower) but the car will go 11.8x. So I spent the last year trying to slow it down to stay in the class. Not much fun. I could move up to Pro, but I really don't like racing from the rear view mirror. Which leads me to making the car go faster. (way more fun) I like racing the Z, and have done pretty well with it. It works well and runs the number, but I know there will come a time when I have to do something about the ass end. It might be due to breakage. But it might be due to rules. I don't care much for the big tire solid axle thing. I like the way it looks, and drives right now. The easiest thing to do is add weight, choke it off and stay in Sportsman. Not my style. So as you can see, I'm waffling back and forth.
  7. I have found that mine has way cooler engine compartment temps with lots of initial timing. What dist does it have? Do you have a vac can? If so, try setting it at 34 degrees full advance without the can, and the hook the can to manifold vacuum, instead of ported vacuum.
  8. Z car IRS vs the NHRA

    The driveshaft loop I built for my truck was a 1/4" wall piece of pipe cut 2" long, and then welded to a bracket. The one on the Z is two pieces of strap bolted together. Since the Z isn't a swingaxle design, I am thinking a couple of clam shells bolted to the transverse arm might appease them. Kinda surprised no one else has run into this issue.
  9. Z car IRS vs the NHRA

    right out of the rulebook. "Cars running 10.99 (*6.99)or quicker that weigh more than 2,000 pounds with independent rear suspension without upper and lower (both) control arms must replace swing axle differential with conventional differential housing assembly (Example 1963-1982 Corvette). Cars with independent rear suspension with upper and lower (both) control arms may retain swing axle assembly regardless of weight or e. t. " Yes, sorry for the confusion. The point I was trying to make was, since the Z only has one trailing arm, transverse arm, control arm, (you choose) there is no way to mount halfshaft loops between the upper and lower, since the upper doesn't exist.

    Some pics of your progress would be helpful.
  12. Z car IRS vs the NHRA

    It appears I am at the crossroads, between sinking $$ into the IRS, or going to a solid. ( I really don't want to cut my car up) I am still .8 seconds away from trouble, but my car is stock back there, except for the ZXT axles. Not sure if I want to commit to making the IRS live, when the rest of the car is already legal to 10.00. I have motor upgrades sitting in the shop, but the car is already too fast for Sportsman (footbrake) and if I jump to the next class, I want to make the car run 10.90's, so I can run it in the Lucas series, in S/ST. If upper control arms were fabbed up, with halfshaft loops, and a set of wolfcreek style axles were used, I wonder if they would let me slide to 10.90. WHOLE lot less work than going solid.
  13. Z car IRS vs the NHRA

    I know there is a lot of fast Z's on here that run down the 1320. (or 660) But with the single trailing arm rear suspension, we are only legal to 10.99. I am wondering if anyone has built an upper trailing arm set up (even mock) with halfshaft loops to get past the rule. I see a lot of you guys spending time and $$ to make them live. How do you get past tech? Thanks.

    PMed. I want the diff.
  15. Pegasus Roll Bar

    While I'm not sure what the Pegasus bar looks like, (the website pic looks generic and not application specific) I can give my input on a couple others. The autopower bar with the diagonal brace limits the travel of the seats, even though MSA says it doesn't. I am only 6.0, and with stock seats it would have been too cramped for me. The base plates were not formed or welded to the bar properly. There would have been gaps. (useless) Or it would have tried to pierce the fender well when sandwiched together. In hindsight, the car is too small to need a 2" bar anyways. I was pretty disappointed with it and just sold it at a loss. Next I ordered a Chris Alston rollbar kit. (probably very similar to the [email protected]) The main hoop fit the roofline very well. but the bases were directly in front of the seatbelt pockets, and to get it back far enough for me to fit, I had to build up the floor so the hoop could attach to something somewhat flat. The rest of the kit was literally a box of tubing. Everything had to be cut and notched to fit. It was a lot of work, but I am happy with the results. The car is street legal (ish), but only sees 1/4 mile duty since I don't trust all the distracted drivers these days. I did run the door bars and while it really stiffened the old flexible flyer up, it is a pain in the ass the get in and out of. Not for daily use, or maybe I'm just old. If you are concerned with seat travel, or seatbelt location, you might want to ask questions before pulling the trigger. And MSA will lie. Just my .02.
