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 $175 Shipped
I machine orders of 3 at a time.

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

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.

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.

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.
