!!!!

First shot!

I was waiting on the IAT to come from DIY Autotune along with my EGT sensor. Well I was running the fuel pump checking for leaks anticipating it coming tomorrow when all of a sudden I hear "excuse me" hahaha . Turn around mail truck dude came down my driveway and I didn't notice. He left, I clipped the IAT in and grabbed camera and tripod. Grabbed a fire extinguisher (on the opposite side of the car closest to me..) and cranked.

THIS IS THE FIRST START THE CAR HAS SEEN!!!!!!

That is truly a fantastic sound, great job you have done there.

started easy, very cool Jon! Any clue about the wandering idle? Lean or too much initial advance?

The idle advance is not fixed because I didn't calibrate the TPS sensor. This is literally the first time the car turned over. Its a completely different motor, 2.9L, 8.5:1 CR, so my old map is not very good for it. It was wandering on my timing table between 12 and 16 degrees advance in the idle bins. I also don't run an idle control valve so it oscillates if idle advance isnt locked.

How was the oiling problem resolved?

pulled the head, machined out the holes wider. Is that the prob you were asking about? yeah that was a pain.

What about the smoke coming from the manifold and/or the turbo ?

Thats oil and grease and cutting fluid burning off.

You feeling ok, Jeff? you just said something (sort of) positive to Jon K!

Yes, that's it.
I need to get a look at one of those heads to understand why it's done that way. Seems a goofy way but I suspect I don't understand it correctly. Having pressurized oil at the head bolt seems to introduce another sealing problem for the head gasket.
Good that you have it up and running. Things were pretty quiet from "New Sweden" for a while after the oiling problem surfaced.

Yeah with work and the other crazy projects going on... it gets busy sometimes you just need a break

Nice work Jon, but having been at sea for 9 weeks, what was the oiling problem in a nut-shell??

Sounds pretty nice Jon, looking forward to the exhaust system, what are your plans? What do you think of these? http://www.turbochargingdynamics.com/category-12-Turbo_Exhausts_and_Parts.php

Thanks Jon

The TCD exhaust is nice - but my setup is custom using a 4" in and out magnaflow muffler and 4" piping all the way back

but first I have to put the cylinder head back on and fix this farking oil leak :(

I think 3" would be a better choice to help speed the hot temps of the exhaust out the back. 4" will cool the Exhaust faster and result in less velocity and cause "more" pressure than 3". Don't sound right I know but simple physics. Now if you wrap the length with insulation tape that is a completely different story.

Arguement emminent...

there's nothing to really argue - supras with my turbo make more power with a 5" than a 4". The "cooling" aspect of the exhaust is not very important as is being able to get it out without having too much back pressure.
OKay, not real familiar with tiny CI turbo'd engines, more with 500 inch plus and thats what I am basing my comments on. Half bank of a 500 inch engine.

Shouldn't matter either way - you want some back pressure, but you want to be able to move a ton of volume quickly. Unfortunately some of the "tiny CI" turbo motors can move more CFM than 500+ block motors.

No need for back pressure in a 4 stroke, its all about the velocity.
Hot exhaust moves faster than cold.
Too large of an exhaust and it reduces velocity but not because of it cooling, larger exhaust actually keeps it hotter.
The problem comes in the the gas can expand further, the same amount of gas is being moved in the same amount of time.
However a 4 stroke benefits from scavenging in that the exhaust velocity helps to pull the exhaust out of the cylinder though has very minor effect on a forced induction engine.
