Starting a turbo build...Videos of it running :D

[theman53]

I have plans for the turbo to manifold 
I want to find a VNT 17vb and then use my AKI 76 log manifold. By that time I want to have it intercooled as well.

[theman53]

I overtightened my oil pressure compression fitting so I am making another. I still don't have the fan sorted out. I know it works since I hot wired it from the battery and it spins. I am just going to throw it together and start driving soon. I have the rear bumper and the interior/fan stuff and then it is done for a while. I will try to post a video of the first trip.

oooh LUCAS its gettin close!! Great Excitement Is Coming!

PRaise JEsus.

Can I still send you those parts if I ever order them? lol

[theman53]

Yes you can send me anything you want...I just may have to test fit them to make sure that they work for our stuff. I would hate for you to pay all that shipping for nothing.
JOKE...I don't even have an MKI running anymore
Seriously, if you need me to recieve stuff and ship it up north it is no problem. I will do it for actual shipping costs unless I have to make a pallet and it costs me money of course.

I drove it and have a video on my phone of the first few stalls. I thought I was in 1st, but I was in 3rd and the new 6 puck sprung hub clutch is different to get used to. I drove it about 5 miles. To the 2 gas stations about a mile from the farm. EGT's were sky high. I had to work to keep them under 1,000 F . I did hit 1,100 once for about .33 seconds.

I had to leave the farm and come back to the wife and the BBQ. I have to redo my oil sender I made out of key stock as it leaks like crazy. I still have some fuel, not much comming out of the barbed return lines that I think will disappear after a few runs.

GILES pump, port and polish, and turbo are amazing. The thing runs like a scalded cat...and I haven't even had the pedal past 1/3 to 1/2 the way down. I don't know I could with the EGT's so high. If you push the pedal it immediately responds. It is almost like it is asking me "is that all you want" LOL I can't wait to rip on it.

I only have the DP on for exhaust right now though. Amazingly just a 3" DP is plenty quiet enough for me. I will definately go 3" no muffler straight back. I won't drive it anymore until I get the leak sorted out. OH my oil temp gauge isn't working either 

[theman53]

BTW I built 15 lbs of boost and then the manual boost controller kicked in and stopped there.
I am worried about the EGT's. I am building boost much more rapidly than the 300D I drive now. But I don't know for sure if I have a boost leak or not. How do you test for that?
Also, I lapped the wastegate, but it seemed ghetto to me. Is there a new wastegate available just in case?
I turned down the main fuel screw 1/8th turn and left...if I am building boost and everything else is good is that how you get EGT under control?
Let this brand new to TD newb in on your tuning secrets. thanks Lucas><>

[lord_verminaard]

Wish I had the answer.  I've got the same problem but not nearly that much boost or fuel.  Haha.

I have an idea that my problem might be a leak from the exhaust manifold or the coldside of the turbo. 

Make sure your timing is not too retarded.

I'm jealous of your boost, heh.

Thanks guys. I feel a little too special when I am the only one on my thread posting LOL.

I have oil pressure sender v.2.0 here that I am going to run over and try tonight.


I am hoping that will fix the leak and not put my stock wire in such a bind since I moved it from the end to the side.
I will drive it some and see what happens after making the adjustments noted here. I have to watch ebay for my amp *hartke* I want too, so it will be tight tonight:D I may wait until tomorrow since I don't have the plates transferred yet. I have insurance on it, but couldn't do the plates. It is actually the wife's car and she hates it, especially now that she has to go to the BMV to get the plates switched. Anybody like primus? "I've been to hell, its called the BMV, anybody ever been there knows exactly what I mean." That is pretty much Holmes county one there.

[theman53]

Have 200 miles on her now. Way too much on boost fuel. Headed to the despirately needed FAQ to figure out how to limit it.

[theman53]

How much weight can the MKII Jetta carry in the backseat and trunk? Over a 300 mile trip. Repeatable without damage #s if someone has that or owners manual info. Thanks

[theman53]

I have adjusted just about every stinking thing on the car and still there is too much on boost fuel. Any boost over 5 psi and it rapidly climbs to 1200 and I let off. I am going to re read the FAQ on making your TD a faster car and do the opposite to try and get the EGTs down. Anyone know how the star wheel works? I thought I understood it after reading the FAQ but when I adjusted it there was absolutely no change?

[theman53]

First fill. 34.8 mpg.
EGTs are pretty much under control. ... It took 7 turns UP on the star wheel and the slope of the pin rotated to the least aggressive point. I got to turn the settings back to where Giles had them to start on the rest of the settings.
Starting to get fun

[gnavs]

Of course the pin is going back to the aggressive point once you're done break-in, right?   

[theman53]

I don't think I will EVER have air cool enough to run the pin on the aggressive side SAFELY. I have even ran the max fuel down to the point it didn't want to idle and turned down the pin to give more acceleration and it is still wicked hot. It almost seems like the pin allows more fuel than what the max screw is set for. I for the life of me cannot see how anyone could use a 12mm head from the 4bt on these if they give more fuel like the giles pump does. Mine is just the 9mm head IIRC. I turned boost up to around 15 and it slows the climb of EGT, but unless the EGT go down exponentially over 15 I don't think I will be running the aggressive side

[lord_verminaard]

Glad you could stop buy last weekend.  Car has a lot of potential, for sure.  Feels like it's just getting started at 10 psi. 

I think the boost pin actually does increase fuel past what the max fuel is set to, if I remember reading the diagrams correctly lol.

Intercool that thing and crank the boost up pronto!
