... this thing will pull all the way to 5000 rpm with only slightlyslower acceleration right at the end...
i sure don't do it every day, but i have done it three or four times.and the stock tach might be off 100 or so but still close enough to say i went to 5000but it doesn't vibrate or make weird sounds and it is still pulling plenty strong so i think doing it occasionally shouldn't be to dangerous.i also had to replace my front crank seal because the old one was a cheapo dnj i think.
these things reach peak hp at 4800 rpm at which point the early has about 105 ft/lbs while peak torque is achieved at 2800 rpm and is about 130 ft/lbs, i believe that the engine was intended to be used in this range(redline is 5400 and normally from my limited experience there is about 500 rpm of overrev designed into most engines), i tach it to 4400 every day and it handles that perfectly fine.
Agreed!...“Well, one has to consider that the Toyota engineers were constrained by various factors-…”
so now that i've driven it for a while, .... i plan to turn it back to stock as it was designed to not harm the engine in the stock configuration......
Yeah, the constraint is I don't have a knock sensor installed yet.
The ears can hear a loud ping, but the knock sensor will read it at a much quieter level
