Steve M Forums Junkie Location: Adelaide Registered: June 2003	Re: 18 rgu tech questions Mon, 23 June 2003 17:11 None of the timing marks on the 18rgu pulley are 5 degrees. I reckon I've figured out why the books suggest different timing. The book I've read is, due to its age and the compression reading in the back of it, for the high compression 18rg. If you ran 12 degrees in a 9.7:1 CR engine I am guessing that it would ping really badly, would I be correct. However in an engine with only an 8.7:1 or and 8.3:1 CR it would be about right. We have an 18rgu with 9.7:1 pistons so we will stick with the 5 degrees. One suggestion to sort out any confusion could be to advance it until it is just pinging and then retard it until it doesn't ping anymore. This worked really well with the old 18r-c we had.
