We always try to come up with new ways & new idea to help the industry we are in. Well one day we sat down and thought, wouldn’t it be a neat idea to help a customer break in there motor they have built here? That way we can monitor the engine and everything it does to make sure our engine are 110% when it leaves here. Well we put that thought to the making. We developed a engine stand where we can put just about any engine we build, hook it up to our engine stand and put the engine to life. Its speed regulated with max rpm of around 290. Here is a video of the initial run with a stock SR20 engine.

ummm.... oil?

I see none, that looks like a great idea that was executed horribly.

Honestly as an engine builder I agree that spinning up an engine to test it is a good idea, but you should also be priming it with oil at the same time. 290 rpms may not be fast but it doesnt matter.

I hope you revise your design or setup before "testing" any fresh built engines.

i'm no engine builder, but i was thinking oil might be a good idea too. maybe they lubed all the required areas before the test?

Snow Trooper

even assembly lube wouldn't last though

maybe they have some of that magic oil in there like the infomercials.... "...now watch as we pour sand into this running engine that we drained the oil from..."

So, you're spinning that bottom end with no oil lubricating it?

This looks like a much better idea, even better if you hooked up sensors to it and had readings coming from the engine. (i.e. afrs, oils press)

Thats the same guys though^^

Snow Trooper

which doesnt look like an engine dyno...

who knows

I'm not sure if any of you realize this but Mazworks has been building cars for a long time and like a lot of you I'm very sure they know the essentials of engine lubrication as much as all of you like minded individuals. So I'm pretty sure they aren't going to build this test stand and then take that same engine and just say eff it here's your motor.

In other words stop being overcritical.

Yea, i noticed that.

I thought spinning the crank by hand a few times to make sure everything cleared was enough. I don't get the point of the 290 rpm test.

An explanation would be nice though.

0MazworxRacing

Umm well of course it will have oil in the system. That block was lubricated and it was just use to test the system out. Were not dumb enough not to provided proper lubrication when testing other engines. This was just to test it out.

Here is a full longblock getting the startup.

So what do you all check after you cycle the engine on this stand and before you give it to a customer.

RACEPAK

its a simtester.

you set the rpms to about 300 and when the engine breaks in you should see a rpm increase

checkout fiatnutz videos on you tube,

xxbulaxx

Do most motors build enough oil pressure at 300rpm? I know my ls1 wouldn't(cranking at 3-400rpm) until it fired up.

MR.johnson

i dont know why you would waste your time.

Snow Trooper

Ok, awesome and thats what I wanted to assume. BUT this is honda-tech and you just never know, lol.

LightningTeg

Doesnt break in require an actual running engine? You cant tell me the rings are properly seating from this

TinyT

no, they are not at all.

this seems really pointless.

mkriebs

Agreed. Doesn't expansion from heat mean anything in engine break in (rhetorical question, because I know it does)? I think this would be doing more harm than good, because when the engine heats up, the parts expand, and would essentially "move around."

Neat idea, but keep working on it.

TinyT

how is it breaking in? the rings arent seating. from my research iv found the only thing a simtest does is let you see if you have oil pressure and to make sure nothing is catastrophically wrong. waste of time, put a motor together right and one doesnt need a silly machine like this.

Desir Performance

Wow you guys are so one minded, we should be lucky and thankful to have guys like T1, Miller and the guys from Mazworxracing thinking out side of the box, the only i see wrong that they did was show a idea before it was completed. I mean think of the possibilities of something like this for the the home builder, completely build your motor and run your harness and a base map then set the rings, check for knock, pull the pan check for shaving etc... all this before installing in the car. This is one of the reasons why we can get ahead as soon as someone sticks there neck out with new ideas it gets bashed down. let these guys finish before you call it silly if anything lets help him improve it.

mkriebs

You don't understand the workings of a motor and properly setting rings and you're EFI 101 certified?

Eesh.

For rings to tension, they need to expand due to the heat of combustion. Without heat, there is no way to get the rings to expand to real world tolerances. When the tension rises on the rings from expansion, the ring would have to reseat in the cylinder.

I'd much rather spend the time putting the wiring harness into the car and installing the engine into the engine bay, rather than a test stand. As for testing for knock, you do realize theres no load being put on an engine on a test stand, kinda hard to create load cells without load. Thats where a dyno/engine dyno comes to the picture. Same way how you can rev your car just fine on neutral with a shitty basemap, but when you go driving you knock the engine to garbage.

As for breaking in an engine, it should be done by loading the engine, thus causing the cylinder pressures to rise and push the piston rings tight into the cylinder wall, you arent getting that by just running and revving the engine.

Besides, if you have to check your newly built engine for shapnel, then maybe knitting is a better hobby

mikeymcm

we used to have similar setups like that in our shop to test compression and to lubricate the engine.
we had two setups.
one setup used emptied out bell housings with a starter on it with we attach to a battery charer.
the other was a small motor with a adjustable belt that mounted under the engine stand, you fasten the belt to the crank and spin the motor.
both worked okay.

mkriebs

IDK man... last time I knitted, there was shrapnel in my scarf. Bad ****!

Regardless, how is an engine going to knock without any combustion?
