adaomakin -- not to answer for Don, but I think he was saying he got the DELTA between heads down to 75F from 275.

I like it when a GT3 is reeled in easily, and a GT2 can be caught and passed.
That is pure track driving satisfaction...

The timing is really hard to compare considering the mods I did. But to answer your question, here is my timing from idle to full boost and red line (linear):

54 kpa 1000 rpm - 11
65 kpa 1300 rpm - 11
76 kpa 1756 rpm - 16
88 kpa 2193 rpm - 32
99 kpa 2630 rpm - 30
110 kpa 3067 rpm - 30
121 kpa 3504 rpm - 28
132 kpa 3941 rpm - 28
143 kpa 4378 rpm - 27
154 kpa 4815 rpm - 24
165 kpa 5252 rpm - 24
176 kpa 5689 rpm - 22
187 kpa 6126 rpm - 18
208 kpa 6563 rpm - 16

I think the timing is actually the weak link in a well tuned CIS motor. I had the fuel head mod (17% more fuel, shaved the fuel pin stop, tuned my WUR (early model) to provide enough cold pressure to start, warm pressure to start and cruise at 14.0:1, and enrichment to provide 12.0:1 at 4 lbs of boost. At idle I had 0% CO. I had 12.0:1 all the way to red line.

With the proper timing, you could bring the turbo to life a bit quicker and back it off on top.

Correct.

thanks!
