Sometimes you feel you need to get there faster...expecially at night... so when the toll barriers are lifted up, u step on the accelerator like never before and the car jumps to the next gear with ultimate response, getting to the 4th gear you found out your stock to 140kmh, stepping out of the pedal for a moment, you hit again, what seems impossible became....... (I reserve my word) giving you the access of up to 7500rpm you feel the power coming out of the exhaust channel as the car jerks to 180kmh getting ready for the next flight of 200kmh....
If I may ask what are the disadvantaged of such high rpm and advantages if any.

Lexusgs430:
Not always advisable to hit the redline, if your engine does have the ability to maintain such engine destruction.
Vehicles like Honda S2000, BMW M3, M5, Celica vvtli etc etc etc
Perform @ optimum when the red line is engaged.

CityNG:


That's not true.

There is no need to ever go into your red line for prolonged times.

Torque is what you need and that occurs at low rpms, unless of course they are on a closed track and doing speed contests then all bets are off.

On a side note, I am getting a better understanding on why well designed cars become a wreck as soon as they land on the shores of Nigeria.

All these high rpm shenanigans, coupled with bad oil and gas plus our total lack of regimented maintenance culture spells doom to vehicles.

Lexusgs430:


I never mentioned prolonged times. The configuration of the engine, determines if redlining is agreeable with your engine.

CityNG:


And I never said you mentioned prolonged times.

Any foray into the redline is bad for the engine hence why the engineers placed a redline limiter on ALL mass produced engines.

The configuration of the engine has no effect on the rpm. Some cars have a higher than normal redline, S2000 and any Rotary engine as examples.

Lexusgs430:


I will stick to my original point, some engines like the S2000 (which I own, is safer to redline).

CityNG:


That's fine but you're still wrong.

No car is safe to take to redline. I don't own a S2000 but I read up on them extensively.

Power drops of at around 8,300 so going to 9,000 is simply a waste and valve float will occur.

You are free to drive your car as you wish but I will discourage others not do bounce off the rev limiter as it's totally unnecessary. There's no power up there.

Lexusgs430:


When you are on a track, you would understand the excitement of redlining !!!

CityNG:


Trust me, I'm the last person you want to preach to about being on the track (both in a car and on a bike), performance driving/riding or redlining

The Evo if properly setup would be a pleasure on the track (but the heavy maintenance service schedule). I Would not be caught on an okada (mum says they are not safe).

No extra maintenance than what you're doing on your S2000 but vastly superior cornering progress and even more so when weather turns nasty.

My has never liked motorcycles starting from my Triumph Tiger 750 that I rode in high school in the early 80's in Ibadan.

PS:

Evos are one o the few vehicles that do not need any setup to compete very well in SCCA.

No worries. Hopefully our fellow forumites have learned a thing or two from our tete a tete

Any car can be upgraded.

Even a Ferrari that we all know is an epitome of automotive engineering

http://www.hennesseyperformance.com/ferrari-f458.html

Just because upgrades are available doesn't mean the stock car is bad. That an upgrade path exists just means that the car is recognized as being receptive to upgrades.

City, some folks think hitting the redlines equates to speed. The 3 SUVs I've own I've never redlined. I've done up to 180km/hr in them and their tacho still read 3000rpm for V6 and 3500rpm for the i4. The higher the RPM, the more you flood the engine with fuel, the more the engine suffers stress built up, the higher your O2 sensors, heater sensors, and catalytic converters get damaged, worst nightmare engine blow out.

I've helped a friend in company of his mechanic pick a Nissan Xterra V6 from Lagos And I was heading to Ondo. His mechanic was driving and flooring the pedal with recless abandon all in a bid to push the truck to high speed. I warned him he could get something damaged he laughed and said "oga, you sef dey fear, why oyinbo put big engine inside motor and I no go fire am? No be today I dey fire motor and nothing go do engine" I stopped at Ondo only for me to receive a call from my guy to rush come to Lampese, Edo. I went there and discovered that the engine had a catastrophic blowout. The piston tore through the banks crankshaft got twisted, oil and water spilled and the engine was wrecked and that was the end of journey. They had to push the truck to a filling station just after Lampese where they stayed for three days and another engine had to be installed to continue the Journey.

The engine was already faulty.

The actual term redline comes from the red bars
that are displayed on tachometers in cars starting at the rpm that denotes the redline for
the specific engine. Operating an engine in this
area is known as redlining. Straying into this area
usually does not mean instant engine failure, but may increase the chances of damaging the
engine.
