andrigs fan

I saw the aftermath of a fan explosion a couple weeks ago at a race over in Ohio ,at least I think that’s what happened. Not sure of the specifics or what happened, but it sure ruined a nice looking shroud. Maybe this composite fan won’t cause as much damage if it does come apart.

I may be wrong, but as I look at it, it seems the hub of the composite fan would round out before the fan shattered

I have a new Berg fan I bought, probably 25 years ago, never used that i just mounted on a alt to check play. Axial was.008", radial was .020".

There are 112 points that would need welded, if you so desire. Also, for the material, intake manifolds have been some form of plastic/glass, whatever for a long time.

Want to see how long something lasts? Try to purposely destroy it. Destructive testing.

I am thinking about getting one of these fans and running it with my doghouse system ( all cylinder tins and flaps ). Where i live i am going to need all the cooling i can get with 9.5:1 compression and the tropical climate.

[mark tucker]

being as light as it is, if the addaptors fit corectly it should need no balancing if the machine shop that made the mold had a clue what they were doing. I would suppose a shop that does turbos could balance them perfectly if some proper sized addaptors were made. truing up run out may help.
I did try to balance one of my fans that I spun up in the shroud.I got it about half as bad as it was, thats as far as I could get it.possiably du to side to side run out. I put it on my 2028 for 80000 mile of lots of zinggers & fun. before I sold the car, as far as I know it's still in there.
one thing to remember side to side run out will try to flex the fan back to a straight non run out plane when it gains rpm, the more rpm the more it trys to "right" it's self. this can be catastrophic for a fan thats not strong enough at the shaft area. I would of liked to seen a spider in the back side of andrigs fan, but it may not be a issue, only time and high rpm will tell,it may not need one. I also wonder about alt cooling, that may or may not be a issue as there are pullys that have fans aswell as some alts that have the internal fan, so it may not be needed in andrigs fans.
in the end we just need to do testing and try to read between the lines. blind test by owners are just that, blind.
If I were to try this fan on the same engine take the air flow reading in front of the fan with std type vw heads then again with super flow heads there should be quite a change in reading due to the different air flow through the heads as the supers have less fins, and a big hole between the ports thus reducing pressure letting more flow through. IMHO you need a fan that will flow and make more pressure than the oe fan. how close to the shroud the fan is makes a differance there too.

I would like to hear a recording or video of the test engine running with this fan. I am curious because Andrig mentions that it sounds louder and different than a stock fan.

Looks like page 3 hasnt sprawled into garbage yet.

Forgive me if it was already mentioned but what is the fan made out of?

The nice thing about this fan is if you really want to balance it even more you actually have material to remove unlike the stock units. You have to be careful on what you take out of course but it's still and upgrade.

I know a hand full of people, and have seen many here on the samber, who complain about how noisy the stock fan is. I wonder if this new one ends up being quieter if it can be marketed as a quiet fan.

Respectfully, read pages 1&2 and visit his website.

I’m not touching the material question as I’ve already gone off on that one.

Andrig clearly tells everyone this fan is louder than stock...

I never really noticed the fan noise on my car. I assumed all that noise I heard on other vw's was those dam pea shooters on the oe fluffmer.I woods thought a curved or even just angles blades wood be quieter and take push more air with less pumping losses. but Im no "rocket sciantest" I just drive the dam thing with dinamite straped to my back....WEEEEEEEEEEEEEEEEEEEEEEEEE BOOM I have worked with lotsa diferent balde types.some are better than others.some are simopler to manufactiure than others. this type weather straight or curved or angled would be no different making the mold or molding it unless a lip was added. it is what it is we will have to waite and sea. too bad rock krushier w=isant hear he claimed to hold pattents of blade desyne and was a ex spurt in his field.

These came in too late. It was 117* last week and I was driving my doghouse type 1 . If the initial reviews don't suck I'll probably order one of these to try. Worst case scenario, I'd rather have a plastic fan explode than a metal one. I've seen exploding metal fans break fins off the heads.

I've never noticed fan noise either...especially when driving. Where I live you keep the windows down or die from heat stroke

Fan noise, what's that? I can't hear a fan over the roar of the 45 Dells at WFO anymore than I can hear it over the whine of the straight cut cam gears.

For all the questions here regarding the materials of construction, noise and balance.
Buy one and try it. For the price point. It's an inexpensive component.
Test it yourself!

I'm on the waiting list. I wanna support a new innovator in the business.
Help the man out.

Remember when HPMX Gen 1 carbs came out? Guess who did the R&D?
You guys did. Then EMPI improved the carbs based on customer feedback.
Hell I have a set of EMPI D-series door stops. Those are gen 1. And suck ass!

The material is a trade secret... OK, 'nuff said. The balance... well, it's so light it doesn't matter to me and I'm sure it's pretty spot on anyway. It looks like a quality unit.

I'm just mainly curious about the sound. I think it would be a good idea for Andrig to post a video or recording that shows that.

Some may love the noise. Many could give a damn about noise they just wanna go fast Maybe it's not noticable, but perhaps it is very loud and sounds like a helicopter. For example, I don't like the sound of loud straight cut gears personally, but some people want that sound. I for one would just be interested to hear it on an engine. It isn't a deal breaker, just a suggestion out of interest. I'm sure a video of an engine with this fan running will pop up soon enough anyhow.

I'm keeping it in mind for my next top end overhaul scheduled for next year.

At 27:25 Andrig's runs the fan prototype, in a 36 HP DS fan shroud.
IMO the electric motor makes more noise that the fan.
