I might be cooking some hoses, but it seems to only last a short while, right after boosting. I know there is a lot more heat under the hood now and I need to address this. I want to heat wrap everything, and I am also considering venting the hood somehow (maybe buy a vented hood?). The oil feed and return lines are hooked up the way they're supposed to, I think. I haven't been leaking oil from them (at least I don't think so).
At first I thought i was smelling crankcase vapors or something from the boost blowing by the pistons, but I raced a 2004 mustang GT yesterday and things weren't too pretty for him heh heh. And as soon as i learn how to launch the car without tire spin all out through first, things will be really bad ass.

you shouldnt be blowing anything by the rings.....they are actually quite good. they are not the weak point on your system and would probably handle 25 psi. if your oil return line is not a perfectly straight downward path to the oil pan, then oil will build up in the turbo and will spit out the seals...this mixed will all the raw fuel running through the system when you roll on the throttle will cause a smell that i would somewhat relate to what your smelling, and it would only happen after some hard boost..
hows it running now? is it still dying at wot? and hows the transition from vacuum to boost?

it's not a perfectly straight path to the pan. It is generally a straight shot down, but the pipe hose has a slight curve in it since I kept it on the longer side. Hmm, I guess that could be it. Marbro also brought up that it might be the raw exhaust gases from my wastegate opening and venting under my hood.
Other than that smell, things are running fine. Transistions are excellent and WOT is AWESOME. As I said, my friend's poor V8 mustang yesterday ate some dirt of mine.

definately wrap that pipe that is coming out of the turbo, because it is right in front of the wastegate. so its running good huh?? alright ......let me know what settings you have the msd at right now as far as when it starts to retard the timing, and by how much per pound of boost.

yeai bet that burnt tire smell is that pipe getting so hot and that rubber boot next to the turbo giving off that smell. you dont want the oil return line to be on the long side though. you should shorten it so its the perfect length. hey and your a good welder.....you should weld a pipe that runs off the wastegate, and cut a nice little clean hole in the side of your side fender and have it exit flush with that...that would seriously be sick.

hahah that would be sick. The funny part is I thought about doing that exact thing. When the wastegate opens up, just have it scream out of that hole. haha. Right now I just have a short dump tube going down, but I'm thinking I should do something like that now.
I'll shorten that oil line though. Maybe that will help things.
If you have those ignition tips you mentioned lightshow, I'm all ears!

yep it deals with your msd ignition. what are the current settings on that. like when it starts to retard the timing and by how much per pound of boost or ATM or BAR

The start point is set to about 2.5 psi. Kinda a safety setting for trying things out I suppose. I have the fine tune knob (in car knob) around 1.5. I'm not sure if that second number is in psi... just the numbers on the control its self.
