Hey, guys, been a while since I was here! Hope everyone has been well and, of course, Happy Thanksgiving to everyone. So, made it to the track with a buddy of mine who has been trying to get his turbo blow-through Chevelle into the 9s. He said I should bring my Malibu and take a few runs, too, so I did. With the new, shorter blower belt on the itty-bitty Weiand 142 my belt slip issue is gone and I picked up just a smidge of boost on the top end. Good enough to run 11.8 @ 116 on a dead-hook launch with NO other changes to the combo- same as it's been for the last ~6 years. (My friend in the Chevelle was the next car down the track after me and he got his nine: 9.95 @ 137. I was on the return road getting my slip so I didn't get to see it, sadly.) So, with that little issue fixed the quest for the 10s is now on for me. All my friends have turbo cars and I'd rather not be the slowest of our crew. At least not by a full second! I don't have the time or money to do much, so the old plate nitrous kit I've got on the shelf is getting dusted off and installed over the winter. My question relates to ignition advance. I've done blowers. I've done nitrous. But never together before (at least not on my own car). The motor is 8:1 compression and I run it with 28* of timing advance because these little 142 blowers are known detonation-makers if you get too greedy with cylinder pressure. Pump gas, obviously. Now, if I throw a mild 100-125HP shot on top of the blower I'm wondering how much timing I should pull out. Normally a shot that small wouldn't require much if any but I'm a little concerned how it's going to interact with the boost. Anybody done something similar could get me in the ballpark with a recommendation? Thanks in advance, guys.
