i just was looking at a s5 and was woundering why they redline 1000 rpm more than the s4?

cos s5 has lighter rotors than s4

only s5 n/a has the 8k rpm redline

My S5 rev limits at 8500 - 8800 - who knows how accurate the stock tach is though - LOL

that is so true, on the dyno my tach read like 4k the dyno computer said 3600 ish

ok so whats going to blow up if i hold my s4 to 8,000. and what ever that is can i just get one off of a s5?

wtf.... whats your concern with this high revving nonsense, you dont even make power up there have you felt hot bad the power drops at high levels??? its worse than 1500 rpms lol

I quite regularly run rev limiter at events - been doing so for 12 years on this engine. If it was a no no Mazda would have made it lower.

I will run ANY car that has a limiter, on it, with no fears.

Dont rev a Celica with a 2zz-ge engine up to rev limit too many times. You will loose a valve or two.

Also the S5's only redlined at 8,000 RPM's if it's a manual transmission. So someone told me. Don't know how accurate that is though. But I've seen it. I was in a 91 GXL Automatic and it redlined at 7,000 when my 90 redlines at 8,000. *Shrugs* So I suppose it's true.
