Anyone test new engines by measuring turn-over torque? Standard Practice in NASCAR

[racing97]

Dennis these other scenarios are just for fun don't complicate your build by this just put the motor in crank for oil press and let it run a while for normal break in.

simulator

The Sim tester simulates engine function without the need to start it.

racing97, you are probably right, but my byline pretty well describes my normal mode of operation.....just by way of example, I actually LIKE Henry's sense of humour and directness, I just wish he would actually say what he thinks once in a while....you know, not hold back too much.

BTW Henry, methinks you are getting my business for studs and machining for my engine (head work, rod work, balancing, boattailing etc....)


Anyway, not sure if there is a SIM here in Calgary, may well be, I will look around to see if there is, just as an option...

Boattailing ? Spend your money on something useful like RS graphics. You'll get just as much performance from a sticker.

[Dennis Kalma]

Yeah, but how does the sticker stay on the inside of the case with all that oil splashing about?

Henry,
Thanks for the info on the Simulator. I can see where this is of significant advantage for people building performance motors. Those NASCAR folks don't miss a beat when it comes to extracting every last pony.
Question. Well actually several. When you run a motor on the simulator, do you note the current draw before and after?
Have you found motors needing to be reworked?
How much HP is required to turn the typical Porsche motor?
Have you found a correlation with easier spinning motors and initial performance?
Lots of questions. Lot of things to be learned with a simulator.
Has Porsche ever specified a torque, HP, details of any kind for this procedure?
When you have time, sure, could you post a picture of a/your simulator, if it isn't a trade secret?
Thanks as always,

[Henry Schmidt]

Have you found motors needing to be reworked?OIL LEAKS ONLY
How much HP is required to turn the typical Porsche motor? THE SIM IS 15HP
Have you found a correlation with easier spinning motors and initial performance? I DON'T DYNO THE ENGINES SO I HAVE NO WAY OF TELLING

Thanks Henry, You ARE the Man.

Thanks for the info. Se I thought that 'SIM' would be an acronym for something deep automotive speak such as:

Spectacular - Ingenious - Motor - Measuring - Device !!

-OR-
Special - Instrument - for measuring - Motors !!
