Slant 6 Turbo 68Dart Project

Well, got a set of 6 new plugs just to do some experimenting with. At $10 for a set of 6 it's ok to have a few sets with different gaps laying around. These ones stock look like they have a setting of .028 already without doing anything, checked on my gapping coin. I'll pop the plugs out of the slant, but I have a feeling they're the same. I did hear from someone that a wavy line near the peak power on a dyno could be a plug/ignition issue, and if you look at the hilltop of the dyno sheet I posted, they all wave up there.

I want to make the most of this setup at 10psi and make it super solid. 10 is respectable and safe, and probably will make the most longevity of spooling the Chinese turbo till I get a different one. I may find someone who can also weld up a more complex charge pipe after the intercooler with fewer silicone couplings. On one of them I saw air visibly escape the coupling while the car was on the dyno, so I know they're not up to snuff really. The pressure in the manifold charges up quick enough, but apparently under higher pressure it does leak, so that needs to be sorted out.

I don't know if you can see it in the video, but in reality it looked like a little puff of air and it was slightly smoky looking.

Someone on a seperate turbo mopar forum suggested I build a det-can system so I can listen to the motor. I REALLY REALLY like the idea of this, and will figure a way to integrate it to one of the inputs on my stereo, so at any time, I can switch to "engine" input, and listen to the motor via a microphone amplifier to listen for detonation and set the timing audibly. I'll make a DIY about it once I finish it. I think it's a rather good idea. The whole limiting of 18 degrees is kind of limiting in the longrun, so higher may still work, and then I could hear it, back off, and change the timing till i get something really well and report back on how it works.

I want to have a very well tuned 10psi system and see what can be done with a purely stock slant with a turbocharger bolted to it. If I get 225whp that would be ...so... cool.
