Fellow board members:

Did a search and found nothing but I was wondering if this has been discussed before...just a couple of questions:

1. What does PS stand for? I'm assuming it's the metric equivalent of horsepower or 745Watts.

2. Assuming that 1 HP is equivalent to 1 PS, why the difference in power between the JDM and US specs? What is the factor in the reduced HP?

Just wondering.

 

I don't believe HP=PS (but it's very close, if my calcs are correct). The JDM engines show 7 more HP because they're running at a compression of 11.7:1 compared to US 11.0:1....the gasket on JDM engines is a bit thinner. Don't know what PS stands for, off the top of my head...

 

Mr. MacGyver:

So it's as simple as that...wow. They are allowed more compression due to their octane ratings at the pump (What is the max octane over there anyways?).

If I were to order a JDM head gasket and install it, will 93 octane be okay to run without causing detonation?

 

PS is also known as "metric horsepower" and it stands for Pferdest

 

Thanks Doc,

240hp x 1.0139 = 243.336 PS
250PS x 0.98632 = 246.58 hp.

Very enlightening.

 

Hi Virus and Doc,

I believe PS is not even equal to the metric Horse Power!

1 HP (imperial) = 1.01386950 HP (metric) = 0.745700000 kW
1 HP (metric) = 0.986320236 HP (imperial) = 0.735499000 kW

Regards,


Peter
