Tin cans rattling under the hood at 5psi.

[boostmaster]

Fresh build and can't go past half throttle or 5psi without KR. I have check everything grounds, cam sensor setting, fuel pump. Just can't figure this one out.

Data logs????

Data logs????

Don't have any I'll have to try and get some tomorrow. At any rate the KR though it is very audible doesn't show up on the knock gauge or the scanner.

180 off on the cam sensor?

Check your water and oil. Re torque the heads. Could possibly be lifting the heads.

Bottle knock means too much timing. Are you using the same balancer from before?

Fresh motor... better pull the oil filter and cut it open. See how the break-in is going.

Cam sensor 180* out , already verified that and no change. Now as for the stock hub.....hmmmm. I now have a internal balanced crank so I had the stock hub modified to remove the counter weight and neutral balanced then I reinstalled the crank trigger. I did'nt think it would have an affect on timing.

The ring on the balancer determines ignition timing. If it's moved, it will throw off timing.

At this point I would throw a timing light on and verify base timing.

Took the ring off to verify it's location against another hub. It is very close but I do need to verify base timing......... I'm getting old forgot all about that. And to boot I gave away my timing light 2 years ago never expecting to use it again. Hell with most of the OBDII cars you can just about verify everything with a high quality scan tool. Compression calculations came out to be about 8.70:1 but even with that I should'nt be getting knock at 5psi.

Any chance you got some bad gas?

 

[Chuck Leeper]

maybe the "knok" is the belt tensioner beating itself to death????

Remove belt turn car on and rev it up a bit see if noise went away also recheck torque converter bolts make sur they are tight
