n20 timing retard question.

I'm wondering when to retard the timing, when the n2o engages or at a specific rpm. I'm running a mild bolt on motor on a stock tune for the time being (until winter when it goes under the knife) and I know I don't theoretically need to retard the timing for safety reasons but want to do it anyway to see if I can't gain a little top end as well as be safer, etc. for example, I'm running an msd6 digital and a nitrous outlet dual window switch with the lt1 plate system at a 100 shot. Should I set the timing retard to activate on the first window stage when the nitrous starts at say 3000-3500 rpms or on the second switch at a higher rpm like 4500 rpms, etc.



thanks.

Here is a diagram I made for another LT1 guy...the wire marked for the Crane ignition retard will connect to the retard wire on your MSD box also.

Stroked96bowtie was correct that you will want the timing pulled as soon as the solenoids are active.



Please let me know if you have any other questions.

ray thanks for the diagram it will come in handy in a couple days when the kit arrives.
