Same here, very nicely done, been running it for 2 years on my 2275 with no complaints.

So did I but the ad is misleading.
It's not welded and balanced, they get them from VW which are already balanced and they just weld them up. They do not balance then after they have been welded.
How do I know? I asked them and what they said was "We don't add any metal to the fans".
I think mine needs to be checked.

Sure. Just like a tire and rim may have runout, yet be balanced.

No kidding?
Mine spins smoother than the other, non welded, I had. The non welded did not explode, but the center hole stripped right out. Perfectly round. Always replace the fan adapter when replacing the fan.

| I think most shops do that-they just tig it with out adding filler rod and do not re-balance. The only place I know that re-balances is Berg. Ask before you buy to make sure if thats what you are looking for. |

You mean the fan hub?
Where do you get that? Do you use OEM? or aftermarket?
I somehow think an old german fan hub is better that any new one, but some vendors are beadblasting old stuff.
Won't that remove some material and make the fit less tight between the fan and hub?

I bought it brand new and new shims from Kustom1 when I got the fan.
Good tight fit.

X2 on Berg. Awesome welds.
They shave metal from on the edges so they spin true. |

I use these on 2 of my performance motors and a 3rd in another complete 2165 engine parts kit. Despite in the ad not showing the grinding on the edges, all three came to me with them.

I purchased one from CarCraft due to price.......came in a empi package. The blades looked like they were brazed & every other one at that. I cannot shim it enough where it's not rubbing something.
Well be ordering a berg. |

Does anyone offer a welded non-doghouse fan? The narrow fan?

At what speed does the stock fan stall?
Are there fans that cool to 5800 engine RPM?
Can short bursts over the fan stall speed as experienced by running through the gears on a street car be tolerated without overheating?
Is the stock fan safe to 5800 - 6000? |

I not impressed with the weldeds that I have seen either...
Most of the welded fans that I have looked at have the little tabs that protruded through the side plates, burned down FLAT leaving a butt weld.
Now relying strictly on the somewhat carbonized welds to hold everything and not the mechanical interlocking of the metal.
All it takes is one bad weld and its all gone.
A somewhat carbonized weld? What on earth are you talking about? You really think that a twisted tab past a slot is a better mechanical connection than a tig weld? Especially with the forces on the fan at speed? Back to school my friend
I would think that some precision brazing would be better because of the
lower heat and a non-destructive flow AROUND the crimped structure
to be much stronger.
You are probably right. And if you did the work yourself if you had the skills, then sent it off for balancing, it might survive at the 7000 or so rpm where the fan cavitates and is no longer effective.
Welded fans are scarry looking to me personally and I have just relied on
the "loose belt slip" to keep the revs from getting to the destruction point.
There is nothing to be gained by a fan that CAN spin at 10 grand anyway. |
I think the point of this was that a cheap welded fan is no better than a non-welded fan, and that a properly welded and balanced fan would allow you to rev without fear of destruction. |

fans do not cavitate. cavitation only occurs in liquids. back to school for you my friend. |

Every nub is not suppose to be welded. Every other one should be, to allow some flexing. And yes air will cavitate

Well that's news...I guess we should inform all of the jet engine design engineers that their calculations are all wrong, and that thrust models are not limited to airspeed through the compressor stage... I am sure they will be knocking on your door to consult. |
