Got my 588s with the 900sc/10-71 blowers and chiller on them. 9.25-1 with brodix alum heads etc. anyone have a recommendation on how much timing to run. I have the adjustable Daytona ignitions thanks in advance

Personally I wouldn't go more than 30-32 to start and gradually make changes. Nice you went with the Daytonas. Lots of flexibility. I'd think you'd want a short curve with an initial around 20. PM mild thunder and see what he ended up doing. He's got 420 MB's with Daytona ign also. How much boost you plan on running?

6-7lbs. The motors before this were 9.5-1 and 38 @ 55-5800 rpm. All same stuff just more Comp and no blowers

I'm not familiar with the daytonas as of yet however will be soon. Are you able to set the start/crank timing also? Btw Id initially aim for 6psi with 9.25:1. Maybe a little conservative but better than the alternative.

Although come to think of it icdpple on here was running same blowers with chillers if I recall at 9:1 static and seems like he was throwing 8 or 9 pds of boost at them. You could do a search on his 548's and see the details to be certin.

Is that his name on here it's not coming up. It would be good to chat with him on jetting tooo

I would keep max between 28-30 at first get the tune AFR's right work on timing after

Here you go. I screwed up on spelling.

You are right in the ballpark, 28to 30 degrees with an afr of 11.8 to 12 @ wot.With a 9 to 1 motor your effective comp ratio is 13:1 with 8 lbs of boost. you better be running race fuel.
