The new turbo engine!

[yvre]

What happened?

[TOM / EINHEIT 11]

here is the finished ,, New, Turbomotor ,, which belongs to Big D of ,, LUFTKRAFT ,,

Big D owns this bug for more then 20 years. He was one of the first ,, Cal -Lookers ,, in switzerland.

Just minor changes were done since then........the engine & the wheels are new.

Wish him luck and many wins on the strip.........

What happened?

When it warmed up, it started puffing smoke and fouling the plugs... junkyard turbo: lesson learned. At least I hope that's the problem.
So I rebuilt the turbo, put a better breather box on the engine, and now I'm still waiting for a smaller oil feed line for the turbo so I can start it up again. I hope my problems will be solved now.

Very clean setup, Tom. Any specs on that engine? Will he come to EBI?

[TOM / EINHEIT 11]

Sam P......

Thanx for the flowers. Yes it looks and works very well. For the specs i have to ask Big D first. Because its brand new...he didnt tell us to much about it.......he wants to test it first and if he is ok with everything we will have the details soon

He will not go to EBI because he has a appointment with the MFK ( motor vehicle controll / tech check ) at the same time and he wont risk a engine damage at the races a day befor he gets the tech check papers for street legal use the turbobug

The last update was a loooong time ago, so here are some pics of more stuff I did to the car.

Although I liked the look of the previous exhaust, I needed something slightly more discreet and quiet for the street, so I started building a muffler system.

Next thing: getting a decklid on there...
My old one was pretty rusty, so I didn't mind cutting some holes in it.





Then I closed up the big holes, and drilled some smaller ones in it. 





I still need to close the hole for the carburetor. Not an easy task, I've spent more time staring at this decklid than actually working on it. I'm doing my best not to make it look too ugly.

That is amazing! Great fab work.   

[vwcab]

Great lookin' car,love the mods.Saw it @ freddyfiles. 

[Paulus]

Look pretty cool !! 

[Wünderwolff]

The coolest thing is, it is really all handmade by Sam himself, complete header of the turbo, rebuilt turbo, all piping decklid ... really all of it.

Everytime I see it I long for a turbo, even though Sam curses the day he installed his 

[sam P]

Aww, don't make me blush...
True, this thing is a pain in the ass, but I think I'm not the only one to admit that turbo projects can get out of hand very easily... That softens the blow somewhat...

Last summer, EBI2 tech inspection waiting line:



The super shitbox was the car that sparked my interest in vw's, so I'm really fond of this pic. Thanks Charlie48ida for this great shot!!!

[yvre]

I've always loved that car!
What problems are you having with the turbo?

[sam P]

Well, the biggest problem is that I'm never really finnished with it. I keep changing stuff, and instead of driving the car -like I did a lot in it's pre-turbo days- it's always in the garage being worked on (or actually more "waiting to be worked on")...

Very nice Fabian! 
Do you use a special filter on your camera? You made my car sparkle in the sun! Or is that photoshop?

Ha i like this car, kinda makes me want a turbo...

[sam P]

Thanks! And since you brought this topic back up, a small update:
I made this:

Boyscout water injection 

[vwcab]

Hey Sam,help me out,but why that water injection,what is the job for that?
And how does it work?

[donder]

Hey Sam,help me out,but why that water injection,what is the job for that?
And how does it work?

 well, (what i think of it) water expands when being heated, thus creating a higher compression ratio in the heads and I even think it cools the gasmixture and makes sure that there is no selfdetonation ( or less fast due to the cooler mixture)
how it works, i assume that the chargepressure of the turbo puts the boyscout bottle under pressure and the water exits through a smaller tube into the carb/collector where it gets sucked in by the venturieffect.the boostpressure makes sure that the amount of water is even with the boost.

Please correct me when i'm wrong, i'd like to know too.

That's pretty much it, Donder. The water injection is mainly used to prevent detonation; as the water turns into vapor, it absorbs heat in the combustion chamber, allowing me to pump more boost into the engine without hurting it. I don't know if it really rises compression in the chamber? The main purpose is cooling. It's the nostalgia way of intercooling.

System works as Donder described, the more boost, the more water it sprays. I also put a valve after the bottle so it only starts spraying above a certain pressure (I can adjust the spring pressure of the valve with shims) And i can change the size of the nozzle in the velocity stack.
I like this system because it's so simple and natural, it just uses the pressure of the engine to work. Plus it's cheap. (Instead of other ways with electrical pressure switches and pumps...)

Sam, that's some sweet work on the deck lid......I ran into the same problem a while back, I just mixed up some glass and had a run with it

Thx guys,for the info about the "water injection".
