Ok. I might get a couple people that dont like this idea but "theoretically" i want to know if it will work and what I can expect.. Let say a guy has a motor that he wants to run a noisy gear drive in.. I know getting rid of the knock sensor will mess with the timing really bad so what if the guy just swapped out his computer controlled distributor for a vacumn advance HEI set up?? I know I will probably get a engine light and thats fine, what I am curious about is if the knock sensor either being unplugged or just not able to do its job will result in any other problems.. like with it mess with any other part of the computer controlled parts of the car? The guy wants to run a noisy gear drive and this seems to be the logical way to make it happen without throwing the timing out of wack.. Let me know guys cause I barely got my feet wet when it comes to computer controlled vehicles...:hail:

 

You can do it but you'll want to get a good ESC module that isn't so sensitive. This way it only picks up real detonation. If you want you could disable the ESC check in the ecm and just run without the knock sensor. Keep your ears peeled every time you fill up on a new tank of gas but it should work alright. Without eprom tuning I think it's a bad idea. That's like using mechanical lifters and forged short skirt pistons with solid motor mounts and a stiff suspension....noise and knock sensors don't go well.
You could definatly do it but like I said, you'll have to run the WOT ESC check patch and disable the check in the ecm. If you don't the ecm will give you an SES light and retard the timing until the car falls on it's face.

 

Just an observation here, but if he is gonna run a noisy gear drive that means he's gonna be running a non-roller cam?! I've never seen a noisy gear drive for our roller cams as they have a different mount on the front of the cam.

 

Roller cams aren't needed. Just hydralic to keep the valvetrain noise down. Mechanical lifters be it roller or flat have to be adjusted for thermal expansion and so they will we loose on a cool engine. Mechanical rollers would probably be worse for noise since the ramp up rates/slopes are almost always steeper than that of a flat tap. I guess the only time the roller might make less noise is if you were bouncing the lifter off the cam lobes.

 

i think he was refering to the noisy gear drive.

all the gear drives for GM OEM Roller cams have been listed as "quite" gear drives.

 

Yes, thank you. I think Jon looking VERY deeply into the noise issue with the knock sensor!! But that's ok! We all have to keep on our toes!!!! :lala:
