this is my plymouth valiant 1965. I bought it really cheap the engine is the small 170 with 3 speed manual and it runs really good. but I'm hungry for something cool so I thought that I should build turbo on it,
I have built turbo on many other cars especially volvos.
there will not be some badass stuff on it. Just stuff I have lying around
(it is the sound I'm after) :p
note that I am not so good at English "i am from sweden"

some pictures of the car








flames! :)

the turbo manifold is under construction


that's it for today, more updates coming tomorrow
 
Amazing work. I see a Mad Max in Sweden. I am guessing you will support it off engine brackets when done.

I have a turbo-charger left-over from my Mercedes 300D's. Thinking it would look neat on my slant someday.
 
Ingenious idea,curious how well sidedrafts,work in turbo installs.Subscribed.
 
Interesting - a draw through turbo.
 
I like the short,straight shot,reduce spool times.Heard of blow throughs before,that Solex makes it interesting.
 
My little 170/6 surprised me , I like it, short stroke and spin happy, subscribed
Welcome mopar_person :coffee2:
 
her is some more pictures, this is what I've done today, oil return for the turbo


the turbo manifold


now it is done :)






first test-start will be tomorrow and I'll film it so you can see how it goes,

BillGrissom = yes i will build some mounts to the turbo and carburetor.
It will bee a mad max construction :p i have had a volvo with a fun turbo placement on but it is scrapped now.

Bonus picture of the crazy turbo volvo :p the volvo had 20 psi of boost :p
 
That really is a neat set up. I would add a heat shield between the exhaust side of the turbo and the brake master cylinder just for some safety.
 
her is the film its alive :) small settings remain

Side drafts are a perfect carb for a draw through under the hood. Something about compressing air and fuel through a red hot turbo scares me a little though. But that setup sure helps in carb tuning, no special turbo mods needed. Is one carb gonna be enough? That is a 2.8L. Bill, That 300D turbo may not be suitable as Diesel turbos have seals that dont work well with vacuum behind them. Looks pretty solid, and very cold there!
 
I'm amazed how you fit the exhaust outlet between the turbo and firewall! There couldn't be much room there. I love ingenuity. I love creativity. Nice work!

I lost you. Diesels don't have any manifold vacuum, since they always run wide open throttle (i.e. no throttle plate). While in boost, it seems both a gas or diesel intake manifold would act the same. I think the only seals are between the oil-filled bearings and each manifold side. Might be other differences with a diesel though. The oil sure gets blacker and worse. The 300D engine is 3.0L vs my slant's 3.7L, but the slant can rev higher so the turbo might be slightly undersized. The inlet doesn't look small though and looks like a standard Garrett turbo.
 
OK, time to find a 1/4 mile track :blob:

hmm great work. It seems you are pretty expert in this mechanical work. Anyhow I like your ride specially the fire strips on the hood are looking great. Thanks for sharing.

Chrysler used a draw-thru configuration for their '84-'87 TI turbos. The center section had an additional seal to keep oil from being sucked in under vacuum conditions. The later blow-thru turbos omitted these seals (for cost reasons I presume). I like the earlier turbos, even for blow-thru as they seem to hold up better.

Using a diesel turbo in a draw-thru configuration may have oil consumption issues.

The turbo trans am was also a draw through. It was a dog.

True. I wouldn't build a draw-thru setup for the street because of the intercooler explosion possibilities, but for racing-only, they might be okay.

I know it's possible to make considerable horsepower with draw thru setups because of examples such as Buddy Ingersoll's 2-liter Pinto that he raced in NHRA's AA/Modified Compact class with great success.

That car weighed 2,350 pounds (with driver) and ran mid-nines at about 135mph, consistently, and won a lot of Modified Eliminator races.

It was a 120 cubic inch motor on gasoline with no intercooler and no water/alky injection. That would indicate about 475 horsepower, or almost 4 horsepower per cubic inch. A 426 hemi making that kind of power per cubic inch, would generate about 1,650 horsepower, so it got MY attention.

It was a draw-thru setup with the stock-type, 2-valve 1971 Pinto motor (the German one) hooked to a Doug Nash 5-speed. It inspired a few copy-cat cars with similar drivetrains... and on built by Buch Ball of Washington (state) ran well enough to grab the NHRA national record. OHIO George Montgomery also built one... all draw-thru cars.

I wouldn't want one, but apparently, they CAN be fast...

thank :) a problem I've noticed with draw through turbo is that if it's cold out side about 20- celsius, then ice is formed in the carburetor and the engine dies, so it is not a good setup for cold climates :p
