[quote=""tabasco122""]apparently a ft lb is one pound of force applied 1ft away from the fastener. So since it was 2-2.5ft of pipe, it would be about 600-750ftlbs lol.[/quote]

Damn. I thought it would be more.

Subarus - screwed up by wannabe mechanics since 1972.

Actually, the two guys who owned that wrx before me were both engineers and great mechanics lol, i doubt it was overtightened.

Are you only talking air compressors or the whole lineup, including electric impacts?

[quote=""mjannusch""]A crank bolt put on at around 150 ft/lbs shouldn't take 600+ to remove. ???

I mean think about that - that'd be like me (not a small guy) hanging on the end of a 3' long breaker bar and the bolt not even moving.[/quote]

One would think that... But try to pull off a virgin Honda crank bolt on a timing belt car. Not many impacts can do it.

[quote=""tabasco122""]shit gets tighter over time. The axle nuts on my first wrx i ended up breaking a breaker bar. The second one required my 300lb self bouncing on the end of a 24" cheater pipe. You do the math for how much force that required lol. Spec is 162ft-lbs. The stake on it also increases the torque needed to remove.[/quote]

[quote=""tabasco122""]Another good one is subaru cam gears. Ive stripped that shit out using a breaker bar more times than i can count, even with the proper fitted 10mm hex. Wont do them without an impact now lol.[/quote]

Truth. I've also stripped those bolts out with proper tools. They're fuckin tight.

I'm getting 813 *nm with a 2footer and 1016 *nm for a 2.5footer. This is if you don't jump on it. I *think, again not physics major lol, that you can gain more force by jumping on it because gravity would accelerate you a little bit.

How did you get to those numbers?

It should just be 2ft*300lb for 600ft-lbs, and 2.5ft*300lb for 750ft-lbs shouldn't it?

Oh yeah, now that you spell it out, it's obvious :lol: OOPS, 813 *nm and 1016 *nm. Which is the same haha. I would do well at NASA :lol:

That's why that one Mars rover crashed :lol: Metric vs SAE units :lol:

It's not that there's tech in them. It's quality of materials.

That said I have that "ultra quiet" oilless harbor freight 27 gallon and it's quiet.

So far (I've only used it for a day) it's good. Decent airflow and recovery.

Imma get a big husky two stage when I’m ready. Mainly for the warranty.

My go to will be a 2 stage Ingersoll but I don't have a place for it so I figured this $330 one will do the job. If I get a year I'll be happy

Older hf compressors were alright but I’d put them on the lower end of the spectrum nowadays.
