No proof needed, only the opinion that two bolts (case half) are certainly not enough to hold the bottom end. I also have had cases with the lip damaged from mounting them this way...

Another two data points:

- My technical editor, Tom Woodford just talked to someone last week who had a four-pronged engine yoke snap and break on them.

- Tom Gould (my Pelican partner) told me that at Otto's, he's seen these engine phyiscally bend and deform under the weight of a fully assembled 911 engine.

To reiterate, I recommend that you only use the five-arm tool, specifically manufactured to hold these 911 engines.

Are you talking about the factory P201 "4-arm" yoke or do you mean the generic 4 arm engine yoke?
-Chris

Yes, the regular, beefy factory, or factory-replica one broke...

Cant this thread just go away? :p

Not until all the cheapo stands (and 2x4's) are cleared from the garages of the World. :rolleyes:

Guys I am sorry to bring this up from the grave but I really cant believe some of the nonsense that has been said here. I was looking for an engine stand and this was on the first page of results.

I am looking for another engine stand(second). I completely agree with what has been said except that it is required to have a 5 bolt specific stand. Those bolts hold the power of the engine on them. You are going to tell me that the engine block is going to be damaged by putting the engine on a non specific engine stand? Those bolts can handle the power/force of a modified engine and then other smaller thinner bolts can hold that power multipled by the Transmission and gear ratio being put on some drag hoosiers. How on GODS earth will supporting the engine on those same holes by any means damage them.

All I hear is hearsay, no proof no nothing. Just a bunch of opinions founded on absurd statements. LOL the ENGINE breaking the cast because it can't handle its weight; that is just hilarious.

For example:
Lets take a 911 996 Turbo modded to 700awhp/600awtq doing a first gear launch. Assume it has all the supporting mods to do a hard launch. Lets see 3.82 First gear Ratio, with the stock differential/final drive just for fun so 3.44.

Torque LBS on the wheels in first gears is: 600 x 3.82 x 3.44= 7884 lbs just to put things in perspective about how much force is envolved with the car running.

Screwing things wrong, not properly securing stuff, not taking addequate measurements will hurt you much more than using a standard engine stand.

How does it hold the crankshaft in or even hold the pistons at 7k rpm. I can see it bending during a honing/boring process(honing plate reduces it or atleast makes it similar to the stress of a combustion cycle) but seriously by the weight of it self? Well I guess that can happen if you use one screw on the thinnest and longers part you can find and then support the engine.

Apparently not!
