Hybrid timing

Postby Chard10 » Mon Apr 16, 2018 10:16 am

Ok so I got my motor back in and running but I was wondering if I needed to set the timing different from factory with all the upgrades I did? Hybrid 2.3 /2.6 with 2.6 valves and cam Weber and pacesetter headers. I set it at 6 but seemed to be reved pretty high ?

Webers have an idle adjust screw, set the idle to 800-1000 rpms at normal operating temps.
You have the emissions deleted, so timing won't be stock. Advance the timing gradually until it starts to ping under load, then back off until it quits, reset the idle as necessary. This should be where it runs best, record the numbers so you can easily return if necessary.

Under load? Do you not set timing at idle?

After you determine the optimum timing, yes. But to determine what's best, you have to do it the "old school" way. You're not actually adjusting it under load. Adjust. Drive. Adjust. Drive. etc. ...

Ok thanks I kinda figured that but just wanted to see if maybe it had already been worked out but no prob! And thanks again it’s been a fun project and I’m ready to get it painted so I can take it down road and stretch it out
