      the OEM bolts were never removed when the crank was balanced.

      Here are the options for Crank Triggers, they all have there draw backs.

      OEM ABA crank mounted wheel.



      This was caused by high WHP 9k rpm shifting. The mounting bolts sheared under extreme shock loading on off throttle.
      Not typical of OEM street car but high HP racing this can happen.
      This happened to me twice before I ditched the OEM setup.

      There are a few options for alternative crank triggers.

      EURO TDI pulley mounted


      034EFI 16v or ABA pully mount kit


      Front/rear main seal trigger wheel



      Flywheel trigger.


      This is the piece i had made to fit behind the 1.8T fluid amper that makes it fit a ABA/ABF hybrid
      all i have to do is drill the mounting holes after i determine where to clock it.

      this piece fits as close to the front main for strength against high rpm oscillation and the mounting
      holes are not adjustable so nothing can move it's position.








      If you like this option i can have the trigger wheel made locally $185 Shipped

      What took out that trigger wheel? I've seen something like that happen before but only when they've been removed and refastened.

      The OEM bolts sheared.

      My new setup fired up on the first pull of the trigger. I am very happy with the results.

      There's not normally much stress on those bolts, any thoughts on why they sheared.

      I believe it was due to HIGH RPM 9k shifting on a 400whp setup.
      the repeated shock loading from shifting from full throttle to full throttle
      over a 1500mile period. this has happened twice in the same amount of time
      which is why we designed our own for duribilty and longevity.

      So checked the timing today... Dead on the money.
      drives great. i smacked 8krpm a few times on the way home. no issues..
      I will be racing it Saturday June 5th if all goes well then yes i will
      make more to order for $250 shipped.
      Keep in mind this Trigger wheel will align the 1.8T pully for the
      ABA accessory setup on a 16V ABA hydrid. I.E. 16v crank timing gear.

      OK well this is the product



      and it installed. Some Assembly Required.

      Accessory pully alignment


      So if you want one it is a 2 week turn around from order to shipment.
      they are made to order.

      update.
      3000 miles daily driving no issues 1 race event 10 passes. all good.

      I have ARP rod/ main/ head bolts. H beam rods, JE forged pistons. ect ect.
      OEM Forged Crank


      Piston and rods

      OEM crank trigger bolts sheered


      OEM Trigger wheel


      New solution, External wheel




      This alignes the serpintine belt pully from a 1.8T to a ABA acessory bracket setup using a 16v Crank Timing gear/ 16v head.

      so there is no way to achieve this on a 9a with ABA serp setup?

      there is a way, after hours on the bridgeport and custom mounts for sensor i have it installed. i need to know how this wheel is timed to ABA OBD2. where on the 60-2 wheel should the sensor point when CYL1 is at TDC?

      034 tone wheel. with ABA space kit. 3 hours on bridgeport. custom spacing on sensor, and wheel set to 14th tooth after the 2 tooth gap at TDC. this is confirmed

      I will be working on my Corrado tomarrow, I will count but i believe mine is 14 teeth before .
      I will confirm it tomarrow.
      I do know this is the same setting as when i used the internal OEM trigger wheel.

      My sensor is mounted to trigger 14 teeth after the space on the wheel at TDC. So the pick up sees the missing teeth and fires at the 14th tooth it reads after the missing ones. this is programmed into my EFI. All Aftermarket EFI are programmable to any number you want.
      I used this setting on the OEM crank trigger wheel and the external mounted one i made.

      This is at TDC. See the gap.

      So this piece is to be used with the 1.8t crank pulley. I'm assuming it acts as a spacer to work with the Ina abf serp setup.

      It will align the 1.8t harmonic balancer or Fluid amper to the ABA Accessory bracket.

      Yeah so my milled ABA pulley from bbm won't work, damn

      Any difference in 1.8t pulleys? I would really hate to buy the fluidampr for around 400

      I just deleted 400 messages. I would score a 1.8t crank pulley from a
      Wrecking yard or buy a used one for cheap.
      A lot cheaper then the fluidamper. The oem 1.8t harmonic balancer
      Is good for 8500rpm.

      I suppose I could, If I were to make a mounting bracket for a VR pick up
      Maybe I should make it for the OEM VW sensor to mount.

      That is 034efi's bracket and VR sensor. the bracket is altered for the position of my wheel. Inside the crank pulley not out side.
      If I were to make one it would look like that but mount the OEM vw sensor. cheaper that way.

      Any benefits of using the stock sensor over the vr sensor?

      Also this is a 60-2 tooth wheel correct?

      Lastly, how much for the whole setup?

      Benefits of using the OEM sensor is you can use the one you have.
      yes 60-2
      not sure with sensor bracket.
      I'll let you know
