Thanks, Ellis. 8)

I think once I get that crossover pipe down to one silicone coupler and some pInt sprayed on it, I'll finally be halfway happy with how the underhood looks. Then I need to make a new reservoir for my air to water and put all the Chevy leaves and shackles on the rear and fix the frame and start on the new front suspension and fix the drip rail rust and put new weather stripping in and put new door speakers in...

I may be forgetting some things though. :mrgreen:

I've got to trek over to Hiney's sometime this week and have him run the camera for me. I found the return springs that the throttle body came with so I'm going to try to put them on tomorrow evening. Have it hold the TB closed longer.

Even a slight load will spool the turbo enough to open it up, and a 4" hole doesn't *kinda* bleed off boost. When that sucker cracks even a little it dumps all the blower boost. It still drives a lot better, I just think if I could keep the blower boost a little longer it would help spool the turbo that much more.

Never, ever tell somebody that, DF. I've been making that mistake my whole life and the second you tell somebody there's no rush they will take it to heart and pretty much never finish what you're asking them to do.


So, my mom calls last night asking if she can borrow one of my pickups to go get Christmas trees. I looked out the window at my Ford Ranger, with its flat tires, empty gas tank, and engine that hasn't ran in almost 6 months. Needless to say, mommy gets to take my supercharged Dodge over to the Christmas tree farm to get whatever she's after. That should be an interesting trip. :lol:

She and her boyfriend actually borrowed it once before to haul something, they were both laughing about the biker they blew smoke on when they gave it back. I'm still waiting for that guy to recognize my truck in traffic and come up and stab me. :lol:


Also, I'm bringing my timing back some. It was 32* out this morning and I didn't think the old turd was going to start. Before the timing bump it would have fired like it was 90* out.

I dug deep into the most desperate areas of my fab skills for this beauty. :lol:

Image

It seemed to help a lot, idle boost is back up to 2psi and there's not as much of a gap between blower bypass and turbo spool now. I also brought the timing back down to the middle of the slots, and unhooked the AFC to make sure mommy isn't putting on a smoke show for everyone.

With no AFC, max boost is 20psi. It's not very wild up top anymore, but whether that's mostly because of the AFC or the timing drop I don't know yet.

I've also developed a belt squeak at any interstage pressure above 5psi. I blame this on the paint I put on the drive pulley, and as such will never paint anything I own ever again. :mrgreen:

She seems to be very happy with where the timing is now, a tooth jumped and back to the middle of the slots. The fired right up this morning, just like old times, and there was a minimal hazing. There isn't anymore fuel knock when revving the engine, Nd the idle seems to be smoother than either of the other two places I've had it so far.


It also doesn't seem to haze as much at idle now. Before the bump, on cold mornings, it wasn't obnoxious but it was pretty visible. With the bump and at the end of this slots, once it finally stRted it pretty much made my entire house disappear behind a screen of smoke.

I started it this morning and stood there watching, and honestly couldn't see any smoke. Or was at least 32 degrees, so it looks like I'll be able to keep my dignity and not plug it in until it gets in the teens. :mrgreen :

I know what kind of video you animals want to see, me decimating a set of 35" Nittos. Those things are too expensive for that. :lol:

Honestly, I've still got to swap the rear leaf springs before I can even try to get on it below 3rd gear, and even then, I don't think it's gonna be blazing the tires off through 3rd gear. My truck has never ft like it had that in it. I'd rather get a drag strip or dyno run vid TBH. Though I still feel the numbers are gonna be pretty weak. :lol:
