Custom made from a shop that already makes pulleys, would be your best option. Non stop tuning would be a good place to start.

Got distracted and bought myself a new crank pulley. Lol

I definitely owe you a beer -- Just took a look in engine bay, and turns out that I didn't have the bolt in the bottom mounting hole at all. It was sitting on a table -- I must have missed the installation of it.

I installed the bolt and tightened the other two. Went on a drive for about 30 miles and I definitely think that did the trick! the RPM rev range is very smooth from 2k up through 4k now. The engine produces a slightly different note at times that I can notice as well and I even seem to get slightly better fuel economy (although I won't know on this for sure until I run a whole tank through). I didn't have a single instance of hesitation once the engine was warm.

I'm glad you pointed this out -- I would have never thought to check for that extra bolt! I'm going to consider this solved!

Same weight loss, different place. good choice.

Is that true? I lost that bottom bolt and ive been running fine for 2 years.

I would say it must be. I can tell a definite difference in hesitations with my car. Your ecu may be fastened to the bar on the engine block more securely that mine was.

I should also note that my car appeared to run fine with the exception of hesitations. So it's not as though that bolt makes a world of difference. Just improves issues in specific circumstances it would seem.

I ran without mine for years too and then knocked the injector cover one day and the car started to randomly stall. Created a map to prove each injector set and when set to DI only the car wouldn't fire up or would die if it was running. Not sure if the car runs any better but it's a purer grounding source so in theory could do. I actually found that on putting it back on was easier than I remember, you just have to find the angle your arm goes in best and just use a ratchet spanner once it's in by hand, rather than a socket set.

I would guess that if done tight the top 2 would either ground via the injector covers or hold it tight enough against the bar on the block, if the latter then you could be running worse due to poorer grounding.

Now I'm curious to know if I have the bolt. Does anyone have a picture of which spot the bolt is that we are talking about?

The plugs would be at the rear, so the lower bolt is the one on the left. Here it is in the bay. You can get much easier access by removing all the loom from it and then have room to get your hand in.



I guess most people don't disconnect it and just move it to one side which is why it seems a pain to put back in.

if you could not get to bolt maybe running a dedicated ground wire to that point of the DI computer would work

I literally was like, I hated taking this bolt out and putting it in. I am just not going to do it. Wonder if adding a ground would help any stutters.

Thats a pretty dumb design if the mounting was the ground instead of the billion wires going to the ecu having a ground.

It's fairly common practice, just about everything is grounded to the engine or chassis and therefore it will be designed as such. If there was an additional wire it would just be connected to one of those so cut out the unnecessary and bolt it direct. Saves on costs of additional wiring.

Fellas it honestly took me 40 seconds to find the bolt, reach down and screw the bolt in. It took me longer to find my 10mm socket. Instant relief.
