I need some recommendations from you 9 second gurus. My best is 10.61 @129 on an unprepped track in Germany. I am running a forged 346 with stock heads, Fast 90/90, and an NX direct port kit jetted to 200hp. I believe the jets are 26N / 14F. I am also running a Ramchargers timing tuner. I think I am pulling too much timing out of the car. I set the tuner to pull -3 degrees every 1000 rpm starting at 3000 rpm. My computer is tuned to pull 2 degrees after 3000 rpm so I am seeing a total of 16 degrees pulled by 6800 rpm. Is this too much on pump gas? Should I pull the timing all at once? I have tried to run 100 octane mixed with 93 octane and the car lost 3 mph in the 1/8th mile. My car also weighs 3650 with me in it. I plan on removing the air bags, passenger seat, front and rear crash bumpers, and the power steering. I am just trying to get a 9 second pass before I leave for Iraq in a few months. Thanks for any info.

What plugs are you using?

Should only need to take out around 8* of timing.

When the N20 comes on you want all the timing out that you are taking out.

I am using the NGK BR-7s for the 200 shot. I have some TR-8s for the 250 shot. 8 degrees is all I need to pull for the 200 shot? Thanks for the info.

Well, I changed to the 250hp jets. I found that I had put a .020 on the fuel side of my #6 nozzle. It should have been a .014. I also had my tuner lower the 2-3 shift rpm and speed to see if it will shift. I am only taking it to the 1/8th mile this weekend in hopes of hitting the 6.40s. Then its off to the 1/4 mile in a few weeks.
