All cars lose HP with age, just wondering how much the HR will lose after accumulating a decent amount of miles.

 

I've heard that these engines get better with age.

 

heard same have a friend that ran 13.5 in his non rev up with 136k mile

 

IMO it's more a factor of how well the engine has been treated. sure, normal, unaggressive everyday driving will still cause wear/tear on your engine components. but, it is nothing like the wear/tear an engine will experience if it is being driven hard everyday, tracked every weekend, full-throttled after every stop light, etc. From that stand point, the HR is no different than any other engine. The better you treat it, the less HP and overall performance it will lose.

coming from an '07 HR with 30k miles.

 

there is no mathematical formula to compute engine wear

 

If it was a regular Chevy LS7 or that silly V-10 Dodge makes it would lose approximately 18.7% by 100K miles. But the HR is God's engine right next to the B-18C V-Tak. So it gains 9.37% by 100K.

 

Too many factors to consider when asking such a question like yours. Have you rotated the air in your tires on a regular basis??

 

+1 to everybody else's post.

 

All things being equal, with regular maintenance and reasonable use, how much HP on average will the HR lose at, say, 100k?

I'm sure there are varying answers but they is also a range or average figure just like two cars with the same mods won't have the same gains but will be within a given range or average.

 

so how much horsepower should I be looking at when i hit 200k? man I guess i need to start driving my car more! awesome news.

 

nope. there are many, many more factors/variations in performance/HP loss due to age/mileage than than with the comparison you are trying to make of gains with mods.

 

06 Blue, That was just something I heard. I know that a 200k mile engine is not going to perform like when it was new. Sorry for the confusion.

 

Like they say, Honda break in mileage is 100k. Hopefully Nissan is the same =D

 

If my calculations are correct, the answer is 5!!!!

 

Another stupid thread. How the heck would ANYONE know this?

 

engine's don't lose power with age (assuming correct maintenance)..

my friend has an 03 Z with 100k+ miles on it and we went to the drag strip together and he ran 13.6 stock (aside from cat back exhaust).. you can ask him his username is britx

 

I have never heard that engines lose power with age. . .If anything I've heard some engines get stronger or break in . .
