Type 1 DTM shroud

[clooney]

there are quite a few threads on this but most are a few years old. Has anyone fitted and ran these recently?

I have had good luck with stock type 1 cooling, but i am thinking of giving the DTM a try for my new build - just for the sake of trying something different

new engine will be 2276, Tims Stage 3 heads CB Snakeskin valves, 1-5/8 exhaust ports Oteva springs, titanium retainers, WebCam 86C, Thorsten lifters, Pauter 1.4, HD aluminium pushrods, 10.5:1 CR, 48 DRLAs, Berg 26mm pump, CSP relief cover, Scat 2 quart sump. full trim, full interior bug, weekend driven , mostly street fun. transmission is 8 years old Rancho built, stock ratios, 4.125, super diff and old SAW axles.

Hi Clooney,
As you may know I wrote the T-4 Upright Conversion Manual and worked with Joe of Oregon Performance the creator and Jake Raby who took over Joes operation.

My manual is based on DIY, with T-1 and T-4 parts using a 36 hp fanhousing with doghouse. Using a T-4 engine and the T-1 fanhousing did a great job up to as far as I can prove 160 hp, and actually heard of more power full engines in Europe.

The DTM was designed to put out more cooling air equally to both sides of the engine. Down The Middle, and also had separate cooling to the oil cooler.

Again never heard of a DTM overheating.

Now lets go into the Gray area !!!!! The Type IV has heads that are 1/3rd larger then T-1 heads which dissipate heat much better then a T-1. Some actually have a hard time reaching running temp..

Even though you have smaller heads with the air the DTM puts out you should not have a problem.

As for the T-IV heads being larger most likely is the reason why my Cali Style worked with the T-4 engine .

As you know the DTM does not have a thermostat, that may be something to consider if you live in a colder climate as I do in NY. Then again your engine is not a T-4 so it may run hotter, which may eliminate the need for a thermostat.


Everything I said was a guess. Lets hear from someone that has a T-1 with a DTM.

It will be interesting.

thanks Joe, no, not concerned at all with no thermostat flaps, i prefer an oil thermostat instead which i run in all my motors.

i am curious to know the fit and finish of the DTM too, especially at the edges/corners and also the manifold area.

Well you will love this story, but also get a good look at DTM construction. This is a Type IV version.

You may have some fitment issues, we are talking fiberglass.

Would it be hard to have a thermostat operating at the shroud intake? Just thinking out loud, I've never seen a DTM in the flesh.

I have seen a few on T-4 cars, as for T-1 DTM's man, I would think think they are a bit rarer.

Clooney, you can see the bits needed for mounting that I show in the photos. Even mine I Had to make my own surround engine tin.

In the photos was the patent in cardboard hand made to make your one tin.

I have one that i am installing as of now and i see a lot of work a head of me.
I will need be be working with fiber glass to fit the case tight. i am finding alot of leaks that are not with OME tin. It just dose not drop on and go,but maybe it's just me.

jg405i ,
Nope it is not just you. But go on Youtube and put in TYPE IV beetles. There are a heck of a lot of DTM, with T-4 . Maybe some T-1, never looked????

I have heard of some install issues and the reason a lot of parts like the surround tin is a issue even on T-4 is because of the age differences of bugs engine compartments.

Even on my Cali Style there is some fitment issues, the guy in this video went is quite skilled and even went into useing heater boxes.

So if they are so great are they still available for purchase for a type 1 engine?

A friend of mine had some bidness in California he had to attend to, and while he was there, (He is a Porsche freak) he went by a place called Powerhaus. Nice looking shop and all. He said they had billet engine cases and building them into 700 hp supercharged and turbo motors....he said they would blow off about any street car out there. Powerhaus uses these fan shrouds. May not be what you are looking for, but they are cool.

Kevin Zagar has had to fit many, and he hates it. They require tons of work to fit. I did one before, and had to slot everything and shorten the alternator stand about .200".

Not a type1, but I did one on a 2.0 914 base engine quite a few years ago.
That combined with the 914 3/4/5 gearing was absolutely epic. That car would keep up with 911's all day long and the engine wasn't a big build.
Cooling was fantastic, constant even oil temp, and no issues on the hottest days pushing it as hard as I could.

I think this was a 4th gear pull. So...it had a ways to go.
