Mine's fairly loud.. but it brings a smile every time it goes off "ahhh that's the sweet spot"


I love making it beep when there's someone new in the car "wtf is that?! is your car ok?!"


Besides, 90% of the time I'm driving, the windows are down to hear the engine and beep together.

 

I'm not adding much here but, I agree with everybody else here. That buzzer is awsome. I'm actually wishing it was a bit louder, oOo also wishing that it had the shift up light, similar to my rx-7 lol.

 

One of the main advantages of having a buzzer 500rpm before true redline is that it allows your eyes to stay where they need to be - on the road ahead. In a turn your eyes are well away from the instrument panel and even your peripheral vision isn't going to help - the rotary is far smoother and faster reving than most other engines and it can be hard to get a sense of where you are in the rev range by sound alone. That buzzer twigs you into upshifting, which should easily be done in the time between when the buzzer sounds and that last 500rpm is consumed.

 

I agree....I have an 04 too and I can barely hear mine... I'd like to think I wore the damn thing out

 

idk why this beep is such a big issue! i actually love it, i redline sometimes just to hear it!

 

ok, so I guess the buzzer is just preference, but on the issue of shiftpoints....clearly the people saying you should shift no later than 8500 aren't really thinking this through. even if I lose power in say second gear for example from 8500 rpm-9000 rpm, I am still going to accelerate with a higher rate than i would if i were to upshift right before that into third, which has about 40 percent less leverage or so.

 

On a full reset one of the options on there shows for the buzzer being "on" not sure if there is a way to disable that unless your a wiring Ecu wiz even so , the buzz saves me from redlinning out and bogging the car in between gears. BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEP!

 

yeah, no doy. it's a mad dyno world.

 

This should be the buzzer:

Have you tested this? Where are you getting this from? I don't know how you're getting 40% more torque in 2nd rather than 3rd (by looking at gear ratios?), but in any case it's horsepower that accelerates the car, not torque. And from the dyno charts I've seen, power takes a real nose dive after about 8,500 RPMs.

Granted, entering 3rd at higher RPMs may give you a leg up when you actually shift to 3rd, but are you sure that staying in 2nd is worth the extra 500 RPMs when you finally shift to third? I'd have to see some real-world numbers to convince me of this.

I'm not saying that you're wrong, but I would need to see some hard evidence to convince me of this.

 

Ok, think of it this way:

When you are in 2nd gear at 8500 rpm going about 62 mph or so, would you rather continue on up to 67 mph and lose maybe 10-15 percent power by the time you get to 9000...or...shift up to third at 62 mph and IMMEDIATELY lose about 36 percent of your mechanical leverage and go down to 6200 rpm where the motor is not as powerful anyway. so basically there is no possible way that you would not be faster shifting at 9 versus 8.5.

 

Peak power starts at 5,500 so you'd actually be gaining, not losing, save for the amount of time it takes you to shift

 

haahahahahhahhahahaha! that just made my day!

 

wow i didn't realize the rx8 makes peak power at 5500! that's news to me. could have sworn it was 8500...


although i am naive to expect a sensible comment from someone who boasts utilizing synthetic oil of the wrong weight no less...



But anyway, the point is really quite clear: the loss of power from 8500-9000 range would not be nearly enough to offset the 36 percent loss in leverage when shifting to third. (the loss is even more when shifting from first to second).

 

I think that he's talking about the fact that HP and torque converge at around that range. Peak HP is around 8,200 I think.

That doesn't bear out my real-world experience with driving an 8. Especially when going from 1st to 2nd, it seems better to shift early.

 

so...losing 65 percent of your leverage when shifting from first to second ( 66/40 = 1.65) somehow is better than taking it to 9000 as you gradually lose maybe 15 percent of your power at most? That makes so much sense it almost makes my brain hurt.

 

So you'll take your potential mechanical gain through the transmission over the fact that your engine is producing less power?

The torque advantage of staying in a lower gear kind of assumes that power is the same in either gear. An advantage in gearing is all potential, it means nothing until you apply power.

 

Learn to read before trying to be a jackass to me, I said peak power STARTS at 5,500RPMs

 

haha you aren't getting what my statement is....

Yes, you do lose power past 8500, but the mechanical leverage advantage of the lower gear more than offsets it. that's all i'm saying.

oh and also check this vid: http://www.youtube.com/watch?v=21HwiUsEmLU why would he shift at 9500 everytime if shifting at 8500 is better? just a thought.

 

Play nice!

.....and to answer the OP's question -



here it is, behind the pod.

A piece of tape in the middle will effectively silence it.

The fact is what kind of power... Torque or Horsepower, you can't automatically assume he knows what you are talking about.

Ok, people from Drag racing should come here, they know more about this.

Good example, http://www.youtube.com/watch?v=YiYpOveuhMI

Look how he kind of bogs down from first to second. Also look at the loss, Can you honestly tell you are losing A LOT of power in second gear? No you can't, and in fact shifting at 9k from second to third gear will more then make up the loss from shifting at 8.5k. Why would you only shift at peak power, won't you want to go further so that you are higher up in the rev band for the next gear. Also the rx-8 doesn't drop off much after redline.... so I still don't see the point.
Mazda should've made the redline to 8.5k to make all you people happy and have a car only redline to a crappy 8.5k and not 9.2xxk.

 

Hey thanx.

now to decide if the process of removing the pod is worth it.

 

Sounds like a lot of people here need to learn about gearing.

All you care about when you're accelerating is accelerating. "Peak output" of the engine doesn't mean a damned thing, it's power at the wheels that matters.

Your total linear force, the total force that you're putting to the ground, which is what matters when you're accelerating, is a function of both your engine's output AND the multiplicative effect of the gear that you're in. Try accelerating at "peak power" in 5th gear and it'll be pretty clear how much slower it is than accelerating at 9000RPM in 4th, no matter the fact that your engine is making "less power".

Just because you lose 5% of your peak power by going a little further along the rev-band doesn't mean diddily squat if you lose 50% of your gearing advantage. Just imagine shifting from First into Fourth. It doesn't matter if you shift at "peak power" or not, you're gonna go nowhere fast. The same effect happens on the 1-2 shift too, it's just a lot less noticeable because the gear ratios are closer, but that loss of gearing advantage is multiples higher than the relative meager loss of power between 8500 and 9200.

The actual feet per second that you're accelerating will be MUCH greater by holding your gear than you'll get by shifting "at peak" and this effect is magnified because when you do shift later, you'll end up that much higher up the rev-band for that next gear as well, bogging that much less.

Go to a track and watch what the V8 owners are doing. It doesn't matter that they make peak output at 4500RPM and it's all downhill from there (and to a much greater magnitude than the RX8 experiences). They're gonna shift at 6800 anyway. Because even though their engine is 'petering out' so to speak, the power at the wheels, the power that is actually moving them forward, is still greater than it would be if they went to a higher gear.

 

ya so thanx for saying basicaly the same exact thing I have been saying, but with more gusto and energy. well done. I don't understand why some people here don't understand what mechanical leverage is.

 

I just learned sooo much reading those last few posts.
