Sensor leads may benefit from using a braided steel sleeve that is grounded at one end. The sleeve acts as a Faraday shield to help keep the leads from acting as a radio antenna and picking up stray voltages (interference) from a noisy environment. I use this all the time for thermocouple leads in my lab.

Yep, It ran with the CHT in close proximity to the lead to #3 so I suspect that it will be fine. I'll loop the sparp plug wires around the back of the tin and approach the plug to #3 from below and outboard of the plug. I'll lead the CHT up and slightly back so it'll be at closest approach about 3" .

The really critical leads in the harness are already sheilded and the sheild is grounded at The ECU.

It seems I have a crate down at the local FedEx Freight depot. It looks like my engine made it from Georgia to Washington in 5 days. That's hauling ass I think in the winter.

Now that Dave's engine is fantastic, I should introduce myself. I will be your next patient!!

Congratulations to you both, it seems like a lot of hard work was put in to make yet another IV scream.

Now if Dave's curse doesn't come back we'll be fine....

BTW- Based on what we saw this week in the lab we may have a 200 HP 2056 before a 200 HP production grade 2270....

All done Kevin, it's at home in the garage. I couldn't pass up the dry weather so I went down about 7:30 and got it. They were also treatening storage fees. It looks like it shipped fine. I've got a big cleanup up in the shop, but I hope by Sunday night to have on a dolly. I can't see getting it in the car for another month or so.

Right on Dave! I can't wait to hear it run! I bet you are out cleaning the garage now. You have the patience of a saint if you can wait for 30 days without at least putting it in the car. (IMG:style_emoticons/default/biggrin.gif)

Made a partial run with added timing, lost power and gained CHT.. Now we are going the other direction with a 2 degree timing reduction..

AFR- RPM fuel values are done :-)

After this verification pull it's time to play with variables like oil, fans and etc...


What are the AFR's and timing curves



I ALWAYS target 13:1

If we post the timing curves someone else will try to use them and may harm their engine, without this cam, CR and set of heads these won't do anyone any good..


What CR is this engine running?
