The plugs have no burn marks on the base or threads. The timing mark is still on top of the ground strap. Way to much fuel in it for now. On the dyno it only made around 800 at this boost level. With 12 psi on the launch and 24 with in .5 seconds. These turbos really shine above 30 psi. We are using tires from a car that runs 4.20's with 30 runs on them. they replace them at 25 or so. It does like timing at this level. drop a degree or two and power falls way off. We are adjusting the tune and chassis. Installed lighter rear springs and adjusted shocks. The video was at 5500 rpm launch will be higher next time. Wheel speed is still slow through .75 secs. Needs more power earlier in the run. And we had snow flurries today. It will be a week or so before the weather clears up. We are hoping to go to VMP as soon as the weather allows. Or a trip to southern states may be needed. We got the shifter problem fixed today, A problem with the shift box. Trans has good pressure and convertor looks like it is on the right track.
You may find out that you don't need to launch at a higher rpm as you lean on the mixture
a little at a time. If you're that rich, there will be plenty of power on hand as you lean on it. Just keep a sharp eye on those plugs. They are your best window into the engine with alcohol.
Depending on how rich you are, you could find yourself leaning out the mixture several times
in small steps before you see signs of heat on the plug. Alcohol runs surprisingly well at very, very rich mixtures. I've been 20% rich at times. It seemed like forever leaning the mixture in. You should see times increase with each step, and should definitely feel the launch pull increase with each step. Don't get too anxious in the process and start taking larger jumps in the leaning process. 3 percent at a time should be fine. As you see the heat starting to come in, switch to 1 or 2 percent changes. You think the power is great being at this rich level, just wait. You're going to love it.
As a comparison note, I've found that my setup is running best with the base burned completely off and the first thread of the plug just starting to show heat, or more precisely, slightly less than half of the first thread burned off. The plating that is.
The ground strap is showing heat less than half the way.
For me, you're in the favorite stage of the tuning. You're going to find a lot of untapped HP as you lean her in.
One more note. As you lean her in, revisit the timing to make sure you're still losing power when you take a few degrees away. If you find at some point that you didn't lose a bunch of power after taking a few away, make that your new timing. The flame speed is going to change as you lean on the mixture.
