Bouncing an engine off of redline without any load accelerates wear and tear. Why on earth would you want to do this to your car?

 

That limiter is there for several reasons.

1. lowers the wear on your throwout bearing which is under load anytime you push the clutch
2. Lowers the stress on your spider gears if you should actually try to launch it
3. keeps you from shredding the clutch on launch

 

Wut?? The new 3's have launch control built in to the ECU.... Bruhhhh......

 

You shouldn't be revving the piss out of anything that's not in motion. High revs = no speed = expensive repairs

 

LOL!!! @ you guys. It's a brand new Mazda 3. The OP has 150k worth of fun before even beginning to think about a clutch replacement or the freaking throwout bearing. Lol. I won't even begin to discuss the engine, which will keep on spinning happily for a quarter of a million miles with ease.

I've owned an S2000, an 8th gen Civic Si, <--- (both with 8,000 rpm rev limiters) a 2007 Scion tC, and now an 89 240SX with an SR20DET and the MZ3. I've revved the piss out of the S2k, Si, tC for 100k each and all were sold with the original tranny parts in perfect working order. No issues.

The 240SX is 25 years old and the imported engine and tranny and fine, bouncing off the 7,500rpm rev limiter every time I drive it.

The Mazda 3 gets ABUSED daily. I'll end up selling it prior to 150k or crashing it before any transmission wear catches up to me. The OP is in the same board. He'll either trade or crash the MZ3 before the so called "wear and tear" from free revving the engine catches up to him. So why not enjoy the car you're paying for? I don't understand people who buy a sports car and keep it in the garage, rarely revving it even 50% of the rev range because they are "preserving it" for the next owner <--- LMAO!!!!!!!!!

 

I've blown through throw out bearings in less than 100k. It happens, and its expensive to replace.

 

Thinking you will get 150k out of an abused clutch is hilarious. You can wreck a clutch in 5k if you're reckless, let alone 150k (hell, you can wreck a clutch in 10 miles if you really want to).

 

I shift properly and rev match when downshifting. I rev the engine sky high but still pull of smooth, quick shifts and have no doubt that this clutch will last me until I'm ready to dump the car or upgrade the clutch if more serious power upgrades become available.

Obviously if you're dumping the clutch during launches and don't know how to properly drive a manual transmission, the tranny will fall outta the engine bay in no time at all. Lol.

My 07 Civic Si was modified and dyno tuned, revving to 8,600rpm. I beat on it daily for 115k miles and even did half a dozen time attack track events with it, all on the original clutch. It was repo'd in perfect working condition @ 115k miles.

You said earlier that you ABUSE the clutch, and in this post you're saying you use it hard but.... smartly. There is a difference. "Abuse" to me means using improperly,and no clutch will last long while being "abused."

to clarify, I am NOT trying to launch off of redline. I only want to be able to rev for fun and it's a little disappointing that I can't go over 4

What exactly is fun about revving a 4-cylinder engine in neutral? Worry about driving your car, not showing your friends around you how you can push a gas pedal down while sitting still. No one cares.

sooo you wish you could do this?

 

In short you cant.
