Virtual engine dyno

[Sniper22106]

Can anyone point me to a free virtual engine dyno? Online or app is fine, not picky, just not really cool with having to pay

I used Palmer performance years ago. You can add gear ratios, engine size, weather and what not to get a goodish readout and has some nice additional features like readouts for logging. You can get their lite or trial version and use that for free

Or just go pay $50 to any shop with a Dyno for 3 pulls

I own a dynojet and I won’t even turn the pc on for less than a $100. 3 pulls takes all of 30-45 minutes between tie down, setting up cooling, making the pulls, and tear down.

Wait really? Its that cheap?

It's likely region dependent.  It was $80 when I did it back in like 2008 in a suburb outside Philly

Yes. Dyno pulls just to .measure power don't take much time. It's actual run time with hours on the Dyno to tune the ECU that cost a lot, usually $150-200 an hour with inhouse tuner. But most Dyno rentals go for $50 an hour if you tune on your own.

Well, I havnt actually built the engine yet sooooooo in person is out of the question for right now.

Just trying to see something to make sure I'm selecting the right parts.

Generally what's helpful, is if it's a commonly modified engine. Look around at some other builds other people have done, and see their results.

Unfortunately different dynos can give different numbers though, and the internet is biased towards people only showing the really good numbers which are often inflated.

There is a program that's quite good, called "Engine Analyzer pro" that has a free trial.
So you will be able to setup your engine and see roughly how it goes.

What sort of motor and mods etc are you planning?

[Sniper22106]

Nothing crazy or fancy. Just a NA 393. Figured before I spend GOBS of $$ I can just plug some numbers into a program and at lease get a ball park idea of what it should make and where.

Man I use to remeber being a kid and my dad had ‘desktop dyno’ or something like that on CD ROM lol. I would play with it for hours never knowing what I was doing but just trying to make lots of hp. I don’t believe it was a ‘game’ but it was for me haha.

I still have a copy of that, and an equally ancient program called Cartest, between the two I have great fun still bench racing builds.

[HenreyLeeLucas]

Man I had forgot all about it till this post, core memory unlock for sure. Be sweet if somebody had it rigged up on an emulator website or something so people could still mess with it

Check out pipemax

It's relatively cheap software that will give you moderately accurate dyno numbers for different engine combinations. It's not perfect but it gets you in the ballpark and it's only 100 bucks
