Racing Beat recommends turbo engines run the leading and trailing set with no separation and no more than 12 degrees BTDC. I tried this with my turbo gen 1 with low boost settings (.6 bar) and found the setting produced low power and slugglish acceleration. I advanced to 20 degrees BTDC on both leading and trailing and improved power greatly on low boost. Also, my distributor is welded up in the "neutral" position. I advise welding up in the fully advanced position, as the adjustment slot needed to be extended with a rotary file to get the 20 degree BTDC setting.

 

so is there any way to tell where that is at on the distributor? how am i supposed to know where im supposed to lock it because without the vacuum advancees hooked up how can i adjust it?

 

couldn't you have just moved the distributor one tooth? And to get this correct you have zero separation from leading to trailing? i thought you just agreed that you should have 15 degrees separation?
