Kris Lauffers Notchback

[Felix/DFL]

Such a good one.Can`t count how often I watched those vids...Yeah the towball is a very neat detail 

The fan is directly fit to the crank(T3)

i know.
i'll elaborate a bit.
the flywheel will come off as well, BUT when is wedgemating, 8 dowling and so on necessary?
so,
the fan will come off, but it might be a good thing to know, what can work and until what RPM, what use, what time... so if someone tested this, maybe it was in this notch.

Hmmmh, BUT the fan turns slower than a bug fan! Ok the it is directly connected to crank and so will rev directly, that is a problem...

So what`s the problem does it explode or does it come loose? O both?
Anyone tryed to weld the typ-3 fan? I think a good balancing job would even help a lot...

Nothing will keep a type 3 fan together in any motor with any horsepower. Doesn't matter if it's welded or anything. First few fast revs and it gone!!!  Listen to Eric Justis.  He lost a few and tryed EVERYTHING.  When his car was at EBI 1 I told the owner then to be careful and it came off. Lucky he was able to save it and get it back on for an easy and VERY careful drive home to England.      Dave Rhoads

@Dave: I had long discussions with Eric Justus and Mark Herbert about that toppic. I can see the problem with the fan mounted directly on the crank, getting all the vibrations instead of getting them softened by a fan belt. I had my fan welded and balanced with the crank and flywheel. Engine is still not in the car but I will give it a try. I don't want to have the type 1 fanhouse in my Razoredge Ghia!

Do you think a 82x94, CB 044 CNC oval port, 42x37,5, FK10, 1,4 rockers, IDA engine would produce to much power/revs to high for the type 3 fan?

@Jason: You said Kris was running a 2442 cc with type 3 cooling. Was that working? How about the smaller 2054 cc motor? Did that one work? With what kind of cam, heads, and so on?
Cheers,

Georg

It doesn't matter if it's welded or anything. The type 3 fan is big and heavy. Any type of good horsepower will rip it apart.  It's the quick reeving that rips them apart. Everything wants to move faster than the fan can keep up with.  Good luck with everything.    Dave Rhoads

Mark and I went over this allot before I built the engine in my squareback too... the issue I see with your setup is more the cam/rocker/carburetors... heavy car ( compared to a bug ) you want your power down low to get it all moving... your choosing things that are going to want to make power at higher RPMS which will push the limits of the fan... my engine is 82x94 all under the deck lid and makes power to 6500 with a small cam - 120 and 44x37.5 heads and 48 dells,  it still makes 150+ and is a blast to drive...

my fan is fully welded center & rosies... and knock on wood... it has not blown up yet... 

on the other hand your carbs aint fitting under the decklid... take the easy way out... just build an upright

I believe the problem is when trying to race.  The RPM's are up high and you drop the clutch. The weight of the fan wants to keep going and the crank has been brought down suddenly by launching the car.    Dave Rhoads

Dave is right. I never blew the fan off my engine while driving it. I spun it off coming off the starting line at carlsbad once, in front of my house and then it finally grenaded right off my launch in vegas. I was fortunate enough the it blew out of the bottom of my fanshroud instead of the top only damaging the shroud and not the body at all. I tried to keep that motor together with that set up as I like having the t-3 set up as well, but racing wise I had to put on a t-1 pulley...and when it got down to it, I enjoy racing more than driving 

[nicolas]

maybe another option is to fit a pulley insted off the fan for races and drive the type3 fan on the street.
for me it wouldn't be an option, as i need something that will always hold, but maybe Georg can hold his foot up and not pushing the limits.

i always thought the square of Anthony pulled great, never looked up the enginecombo, but what you say makes a lot off sense as well.

and just to be sure. you don't want the fan to blow up, i had one that gave way (not at high revs, but because it scraped the tabs away against the housing) and that caused allready big problems. i found fanpieces everywhere, even stuck between the cylinderheads.

[Felix/DFL]

The best it ran was a 12.24 @ 109 N/A with all of the type 3 tin. Only the 48 IDA's stuck through the engine lid.

Soooooo how could that happen than? 

Maybe I had only luck but I never had any problem with my 1776cc with orig. fan, and I was launched not the softest way. Best ET 15.0. Max rpm 7000 1/min

The 2.2 I am building at the moment will also get the complete typ-3 tin (welded and balanced fan). I will see what happens and do some feedback if I bet on the wrong pony or not.
In my taste a typ-1 fan just looks wrong in an typ-3 back. Then you could even transform it to an porsche style fan to get it even more worse in style. jurks...

[Gary Justus]

7K ?......That's a butt load of rpms. You'd better check your tach. That video showed a nice, but modest run. That ain't hammerin'. There's a world of difference between 15's and 12's. Eric had extra long bolt, numerous balances and welds from people who know what they're doing. You've gotten a lot of good advice and guidance here.

[Felix/DFL]

Just to get it clear of course not 7k launch rpm  Mostly I came of the line around 4k.

YES 12`s are not really comparable with 15`s. My new aim is in between. Extra long bolt sounds as a good idea!
Maybe someone has got a pic of a good welded typ-3 fan?

[PIMPPRIDE]

another thought that could factor into saving my fan is I only lightened the flywheel to 14lbs... not the usual 12½ and start with a very very nice late model fan.. or NOS one if you can find it...

Anthony / ISP WEST

[RhoadsVW]

In that vid the notch spun the tires a lot so the rpm's never droped that much. If it would have hooked up at all it would be having fan problems.  Dave Rhoads

Anthony, I just love the look of a type 3 engine with just IDAs sticking out of the engine bay. To make it look more stock, I had the cutout widened by the Bug Box so that the IDAs fit. 
As the car was and will be a street car with just occasional racing at the lights... ahh... christmas tree on a race track of course... I hope it's holding together.

[PIMPPRIDE]

that does look dam good... plus you will benefit allot more from the tall intake manifold vs. being stuck using short type 3 ones... being squareback forces me below the deck...

Looks good Georg.When will it be ready?
 

[Bryan67]

Seems like if you`re running IDA`s and you`ve opened up the engine compartment why not just use type 1 tin and fan?

[Rennsurfer]

The engine compartment on a Type 3 always looks scenic with IDA carbs.
