Searched and couldn't find anyone but most of the users are in the 7-750 range.

If you plan to wring out the gears and hit those high rpm shifts on a FI s550, I would say better safe than sorry especially since it's usually a fairly easy job to be done while going FI. On a non FI s550 unless you are making some crazy high hp hardcore build I wouldn't bother with it.

I got a 17 GT and going to take my chances and "not" do them with my Whipple Stage 2 kit. See what happens.

My friends 2018 whipple gen5 A10 broke the OPG at the track with less than 5k miles on the car. 10 rib kit 20% lower 3.75 upper, fore fuel system, e85, trapped 117 in the 1/8 and opg went right after he let off. He said the A10 downshifted really hard after he let off and then no oil pressure. I took apart the engine myself, all the bearings were toast and there were was metal in the oil pan. Scared me into doing them in my car.

The people that have replaced them say it has to be done. The people that haven’t say they are not worried about it. Some snap off snouts after replacing OPG. Some don’t.

Going fast is expensive. Spend your money how you see fit.

Exactly right.

Hopefully stock crank pulley!


Couple useful tips if NOT doing OPG/Crank sprockets (my car makes 913 whp and is 100% bone stock long block):
1. Keep it off the rev limiter!
2. Keep a reasonable rev limit--7500 rpm is usually enough. If centri blower car and you need more boost, pulley down vs. more rpm.
3. Keep the stock balancer.

ya'll need some snake oil to go along with your opg's?

Replaced mine in my 18. I'm well over the 900 mark though.
