rpm question
at 70mph... what should the rpm read on a 6speed manual??... mine reads 3500 rpm on 70... i dont know if thats normal or a defect on the car... anyone knows??? i think thats a little too high at 70mph...
|
normal
|
you sure?? dont you think thats too high??
|
I'd rather it be lower, but given the low power output that the motor makes in the lower rpms, you'd have virtually no acceleration in the highest gear.
|
yea whateva.. but im saying... are all rx8 manual like that ?.. i mean the rpm hittin 3500 at 70mph??
|
The gear ratios are not going to change from one car to the next.
|
At first, it does seem quite odd to have the rpm's so high at only 70 mph, but remember that you've got almost 6000 RPM'S TO GO!!
Rotary engines are always like that, perfectly normal. |
okay.. well i was just wondering... make a note of your rpm next time you drive... man... i was about to bring hell to them dealers at mazda! .hahaa... i guess they got lucky...
|
3500rpm is high on a V6 or V8, this is a rotary the experimental limits of this engine are 13000rpm (blew up at 14000rpm), fewer moving parts=happier spinning at higher rpms
|
The engine doesn't involve stop and go motions, it's spinning around. Much smoother and rev happy.
Also in case you didn't know, the rotors themselves spin at 1/3rd the displayed RPMs, so most of your car motor mass is only hitting 3000 rpm when you are seeing 9000 on the dash. Look at this video: http://www.mazdarx8.co.uk/upclose/vi...699&video=macf |
Not to worry.
3k translates to less than 1/3 max allowable. The Renesis is unstressed at that speed. |
its correct 70mph at 3500... i think on the website somewhere... i ono where but it says you should go 60mph at 3000rpms so yeah
|
19-20mph/1000rpm in 6th gear
|
3000@60 you can add500more for every 10 mph in 6th gear
|
4100@80 so yeah you're ok. Ok, I think this thread is dead.
|
6th gear roughly equates 20 MPH per 1,000 RPM. So your exactly right on the money!

It's not even that unusual, Hondas are the same. A Prelude spins at about 3,500 rpm at 70 mph in top gear. An Integra might even be higher.
