Redline?
#6
LOL, he's obviously being sarcastic hahah... BTW, the RX8 can happily rev past 12K but there is no need for that since it's way past peak power...
As for the redline on the tC... Once again, anything over 7 wouldn't be needed since it'll be way past peak power once again... I know I wouldn't wait for it to hit 7 to shift :D

remember the 2AZ will have one thing that the current toyota performance motor won't have (2ZZ) low end torque. this motor does not need to spin past 7000rpms to generate power. in fact whenever someone gets one on the dyno i'm pretty sure power will fall off after it makes its peak power @5600rpms. sure one can argue that on the next up-shift will land higher in the powerband but again this car will make its power a lot lower than what i'm used to. on a n/a high revving motor you want to land as high as possible in the next upshift cause the 2ZZ doesn't make peak torque until it hits 6800rpms and 7600 on the horsepower. with the 2ZZ, B18C1/C5, K20A2, F20, you want to take it as close to fuel cut off, but if you were driving a f/i or big displacement motor its not neccesary.

You don't want to land as high as possible.. What you want to do is land in the meat part of the torque curve... Depending on if you want to do short or long gearing... And obviously since "peak" power is at 5500, anything other than 5500 is going to drop...
Just because it peaks at 5500 don't mean that theres no advantage to going past it... If the curve is relatively flat, then having a redline all the way to 10K wouldn't be an issue... (other than the obvious engine ware...)
Just wait till people have dyno, but just be ready to make quick shifts when you buy the car...

Still, "as high as possible" does not fit for any car... The correct definition of the perfect shift is "land on the meaty part of the torque curve" That means either a bit before it or RIGHT on the peak... Being as high as possible mean a car with say 8K redline, but peak torque is around 5K... If your gear is set to ____ into next gear at 6K while redlinning, you'll actually be slower compared to shifting at 7K... To meet the 5K torque power...
It's no biggie tho, but if you played enough racing games... There are other combiniations you can do to a transmission to enable you to be quick or faster top end... But idealy, no matter what you're trying to do, you want to land in the meat of the torque curve...

that's why i said shifting at or near cutoff in a tC has no performance benefits unlike a celica gts, s2k or rsx-s.

name me one high revving motor that revs @8k that has a peak torque at or around 5000rpms.
My point being, redlining a motor is NOT the fastest way to accelerate... The reason why you DON'T see 8K cars have peak power around 5K is because everyone who builds a car knows this is not useful and having a higher redline which will slow the car down will only wear it out faster...
I see what you're saying for the GTS, and I know you have to keep it in lift... But still, what you are trying to achieve is to be on the meaty part of the torque curve on the up shift and NOT be as high as you can be on the up shift by staying as close to redline or past redline....
That was my whole point...
I'm not trying to diss or anything but obviously you aren’t familiar with Honda and their technology involving high-rpm engines. The 00-03 Honda S2000 has a redline of 9000rpms (not to mention the ideal shift point for the S2000 is 9100 in order to keep VTEC engaged) and most of their other models including their Acura line up have high redlines for example the Integra Type R has a redline of 8400rpms and one extreme example would be the Spoon S2000 which has a 11000rpm redline... so to say that "it is impossible for the TC a standard piston engine to achieve such a high redline..." is ridiculous. Also... theoretically, a rotary engine has no redline but due to the limitation in materials and such, it is still set at 9000rpms

If I had a motor with an example right off the top of my head, why would I use that as an example?

when i first got my car i ran it in pomona, carlsbad, autox at qualcomm over 2 dozen times and took it to streets of willow twice. of all those track times the 1/4 mile track showed me my cars performance in the straight line the best. if i fell out of lift/powerband my times were always slower when i landed in lift on the first upshift. the higher i landed in the powerband which brought me closer to peak torque and horsepower the better my times got. when you drive a high revving car you have to take it at or near cutoff so the upshift gear lands closer to peak torque and horsepower, cause peak torque and horsepower is not going to be @4000 or 5000rpms but over 6k and 7000rpms. why do you think silencei2 wrote this about the s2k.
The 00-03 Honda S2000 has a redline of 9000rpms (not to mention the ideal shift point for the S2000 is 9100 in order to keep VTEC engaged)
