im running 420's, SFMU, SAFC, MSD Dis-2, and my timing adv. at 16 psi is 17-17.5. my STFT are an avg. of +7. how much timing should i pull? sorry if this is a tad scattered of a question. im not all that familiar with the adj of timing in regards to WOT and high psi tuning.

thanks
tim

none IMO

Yeah don't pull any..just be sure to use at least 92 octane gas

you shouldent have to pull timing unitl up around 20 psi

best time so far 14.3 @ 101.1mph(no traction)
fastest 2GNT with a hitch! until proven wrong...

yea, around there.. keep an eye on the advance as you keep upping the boost, start pulling timing past around 20 deg i say... and umm, make sure you give it enough fuel :-)

~17 is almost perfect for 16 psi. I have run up to 22 psi on stock ignition timing. I had to run it a little rich at the 22 mark to keep the egt's down, but it worked well.

I ran 18psi the other day on the dyno and I only had 17deg. timing.

yup this is exactly what my car hits all day.

No timing needs to be pulled

I also remember Matt_95tgs running 24 psi on the S16g with stock ignition and stock timing (around 17 degrees)
