I feel sorry for you guys. Gotta wait till to 5250rpm before your car starts really moving. By 5250rpm I'm already pushing 300 horsepower. AMERICAN MUSCLE BABY!

I have a 98 prelude with low miles, vtec used to come in at 5250 rpm (factory specs) but after buying it in California and driving it home to Idaho, vtec comes at around 5500 rpm. It doesn't come on as strong and noticeable as it used too. I am wondering if this is due to altitude change or a problem with oil pressure (too much oil being added to engine when it was changed?) I would appreciate any comment concerning this matter.

"I feel sorry for you guys. Gotta wait till to 5250rpm before your car starts really moving. By 5250rpm I'm already pushing 300 horsepower."
...and after getting to 5250rpm the low-petrol warning light pings on and I pull over and fill up the petrol tank while the Daewoo Matiz I just overtook passes me by.
"AMERICAN MUSCLE BABY!"
You weren't one of the bad guys in '2Fast 2Furious' were you?

Sorry lads, you're all wrong. The VTEC RPM you mention is a guide and the shift to the higher rate cams is governed by oil pressure alone, though this should occur at the aforementioned revs. And don't be too hard on the yanks, American muscle is cool, it's just not as fast as what spawns from every other corner of the globe.
Apart from the Ford GT40.
Which was designed and built in Britain by the British.
And the Cobra was built by an English company called AC. All Carol Shelby did was put a huge engine in it, and ruin the weight distribution and balance of the car.

Has any american car ever beat 100 hp/liter on a non-turbo engine?
From the factory I mean.

Yes, it definitely kicks in at 5250 revs, though how anyone could fail to notice this escapes me.
