RPM to MPH

8589 · 04-03-2009, 01:06 PM

3.000 RPM's = 65 MPH
or
4.000 RPM's = 87-88 MPH

Both numbers in 5 gear, is that about right?

i would say just about, ive never paid attention to the rpm to mph conversion.

My 3rd gear goes all the way to 80 at 4,000 ish rpms is that normal? i never use 4th or 5th

YEAH, THAT'S OK ...4rd is for passing and 5 for jumping bridges/buildings stuff like that

not very worry but I read of owners doing mid 30's to 40's on a gallon so made me wonder since mine get constant 25 mpg every fill up

yeah normal.

What about my car making a superchager or electric car noise every once in a while? lol my car has a 5 sfe engine & sometimes makes a cool sounding noise.sounds kinda like the road warrior when he press the button.it happens once in a blue moon but when it does it last a while.

LOL! please explain this noise a with a bit more detail... does it sound like it has a blow off valve? or does it sound like you have an after market air filter? not sure what your saying?

I send your Q to a mind reader, she said: engine will blow up in the 6 bluemoon, engine is 5 SFE (short for safe)

My SC seems to get about 20.5 mph per 1000 rpm, so I am at 61.5 mph at 3K rpm and 82 mph at 4K rpm. The NA will be at higher rpms at the same speeds.

Riding in high gear on low rpm will get better mileage but fouls plugs faster. I mean you don't want to ride around going under 2500 RPMs. You'll get alot better mileage if you use 5th gear when going 55+. Of course you won't sound like you're destoying your engine.As for the sound, is it when you are slowing down? It may be the tranny whining.

I've heard throwout bearings make a weird noise. I'm only 19 and I dont have much experience with that but from what I've heard they do make noise when they go bad. Maybe?

you seems to have mastered your SC

mine is a blend and a foster child so DNA is not available. so appears my engine goes slightly relaxed at highway speeds which I like, thanks.

also PM send

swift978 · 04-05-2009, 11:30 PM
