Finally Going Single! Part 2 by cohbra

Got the car out again today. It was perfect weather for cruising around in Colorado. I've got some issues with high EGTs while cruising that I need to work out, but in general it is running pretty good. I still have a small stutter in my idle every couple of seconds that really bothers me, but I'm not sure if it's a miss in the ignition with the new coils or if it is something else. I've always had it, but I was hoping the new IGN-1A coils would fix it.

On a side note, my new 3D printer should be here in the middle to the end of next week which opens up a whole new door into fabricating parts. I have been talking to a local casting facility who can cast parts for me after I create the molds on the printer so I'm really looking forward to that.

Well, it's been a long-time-coming, but Steve Kan is finally going to make another visit to Denver two weeks from now. In preparation for cranking up the boost, I spent the last few days working on the car, mostly I was trying to get a solid pressure test on the entire intake system. I never realized just how hard it is to hold back 30psi in a 3" pipe. What a pain in the A$$ that was. I ended up having to double up on all of my clamps. The next test is to get everything hot and see if it will still hold. I also had to put my UIM in the mill and shave off about .015" to get a good flat face on it again. 

Now I'm left with trying to decide which plugs I want to run, and I honestly don't feel knowledgeable enough in that area to feel comfortable with making my own decision. I want to ensure that I'm fully prepared when dyno-day comes. The plugs I'm running now are the NGK R7420-105's all around. If anyone has some recommendations, I'm all ears. I'd like to have an extra set before I get on the dyno, but I'm not certain that I want to stick with these NGK plugs I have now.

Since it's been a while, and to refresh memories, here's my mods. I don't really have a specific HP target, but I intend to let Steve push it as far as he feels is safe for the mods that I have.

Mods: To4z 0.7 a/r turbo, Pineapple racing built street port w/OEM 2mm seals, Power FC, 3 Bar Map sensor, Water/Meth Injection, 850/1680cc injectors, FJO low impedance injector drivers, AEM Uego Wideband O2 sensor, Dual Walbro pumps w/ -8 supply & -6 return lines & separate 10 gauge wiring for each pump, AVC-R boost controller, synapse 50mm wastegate, IGN-1A marine coils.
