tuning N/A 3800 WOT timing

[GPGTP]

my experience is with L67 sc'd 3800's so I'm not use to the n/a timing requirements. A buddy of mine has an 04 GT, I'm not sure what kind of max timing these engines like. Can you guys help me out?

23-24 degrees.

dont be surprised if when you scan him you see higher max kr values stock than you are used to seeing with L67's on an initial scan , every L36 car I have scanned has shown 8* or more stock

L36's are higher compression than L67's and most people run them on 87 octane not premium like the L67 requires so they tend to have a lot of kr lower in the rpm's thru midrange - basically the areas where you would not be in boost with an L67 , up top they can take more timing than your typical L67 will like Brian is saying

00 Impala here, I could only go 18*, 91 octane, but 100* heat....

I took the belt off my SC and was watching nearly 40* at WOT (since NA puts me at a different area in the timing table, ie not the .92 column). Of course, I was still commanding SC'ed AFR's so the wideband was reading about 11.8:1 which is fairly rich for NA. Thing actually hauls ass though for being NA! Especially when you take into account I'm running a blower cam (XP) with stock L67 compression, L67 intake "runners", and a giant chunk of aluminum blocking the intake path (the supercharger).
