Hey guys I'm not sure if this questions been asked but I tried searching and couldn't find it. I've got an 95 LS and I heard advancing your timing is something cheap you could do to get a little more hp. I've also been told to use high octane gas like 93 or 92 and not to set it above 18 btdc. Thing is, I can't seem to find anything higher than 91 where I live. Is that gonna be a problem? Has anyone advanced their timing? Any help?

 

I am not positive about the LS, but as the the R, the factory range is 14-18 degs. So you should not have a problem if you set it at 18 and run on 91 octane.

 

damn they lowered the highest octane available in cali down to 91?!?!?!?!!? damn yall are getting SCREWED. Im surprised noone has raised holy hell over there about it

 

I don't know if its all of cali, but I know I've looked around my area and all I can find is 91, anyone wanna confirm that? And thanks for the 411 stageone, I think I might wait for someone with an LS to post just to be sure though.

 

The 91 oct. is for all of Ca. The engine is suppose to be @ 16 BTDC =/- 2. You could actually run it @ 18 BTDC & still be within spec. That is, of course, on unleaded reg. I am running my car @ 21 BTDC on premuim. I did have it higher but decided not to push it. I never had any detonation, etc. I also run the colder of the two recommended plugs since my car is race/track only car. I know of several people doing the same in tegs( both ls & gsr).

 

i'm running 20 degrees but you don't want to know how much i'm paying for gas!!

 

well all i know my is distributor wont go further and cam2 purple is addictive

 

So no one else has advanced they're timing?
