I was not sure what advice you were trying to give
Your last reply is the sort of direct answer that I wanted. If you have a Civic then your advice is what I want.
I have several very old British carb cars, and what stops them revving is the breathing, which also represents a steep decline in torque. When you say "increasing the revs on the same engine wont decrease torque but if it wont rev higher the formula cant be applied" does not make sense, because if the torque wont decrease then the engine will rev higher. With or without a formula, if the torque does not decrease then the engine will rev higher (if the rev limit is removed) which means that the engine will deliver more power in lower gears.
However you then say "honda didnt just cut the revs on the accord for a longer life - they cut it by detuning the motor which of course does make it more reliable because there is less stress", which suggests that if I get the rev limit removed, it will be pointless because the breathing will make the torque drop off rapidly as it goes over its present electronic limit. This point of your does make sense.
I'm sorry if I appeared to "suddenly become an expert" but ambiguity confuses me. With the electronic limit removed then either
- the engine will rev higher without loss of torque
or
- at higher revs the engine will no longer breath and so there will be a loss of compression on the pistons (loss of torque) which will be dangerous for the pistons
On my engine it seems strange that the high lift cams only come in at 6000 and then the engine hits the end stop at 7200, it just feels as though it would go on to 8000 without loss of torque. But will it ???
That is what I want to know, without ambiguity, and also where I can go to get the rev limit removed if this is safe to do ?
Alternatively, where can I go to get the engine remapped so that the high lift cams come in earlier, hence more torque (power) earlier in the rev range ?
Finally, if I decide to get serious on this engine and go to improve its breathing, where to buy parts and the sorts of prices ?
