can somebody with a s5 turbo please tell me what your redline is.....


thanx

 

7 grand

 

Before anyone says "I thought S5's had an 8000rpm redline", that was only for the NA engine.

 

unfortunetly i have a n/a body and my tach does say 8000 rpm redline but i thought the turbo was lower and im glad i asked.....thanx for the info guys

 

whoa, are you serious? damn, ive been reving to 8 grand since ive done my swap... my fuel cut is at 8.5k, any adverse affects doing this? my buzzer goes off at 7900, so this must be a function of the tach instead of the ecu?

 

the S5 turbo redline is lower then the NA because the stock turbo sucks and doesn't make power past 6500 anyways.

 

The stock tach is so inaccurate that you were probably only revving it to 7500 rpms, which is fine anyway.

im not going to break anything am i?

 

not if you dont do it all the time. Revving it high is always going to take more life away from any engine than say if you revved up to lower rpm's. Eventually, it will break. Not doing it often will = more life. Its your engine, do as you please.

 

^ nah, i dont think so, i doubt S5 na vs T2 engine parts are differnt enough for mazda to change the redline because of engine durability. what is the optimal shift point then? maybe a drivetrain differnce?

 

Tach off? What I never heard of that, so how am I supposed to know I a idling right,...sounds like a personal problem. Maybe the 3800 rpm hesitation is really 4200, or 2300, who knows!!! Getting some TII driverain huh, me too, I bought a S5 tranny for 150!, lets not talk about the shipping though

 

yea, my 5th gear went out. i found a few tranneys, but i cant seem to find a differntial anywhere. you wouldnt have or know where i could find one do you?

 

call japan star they might have a s4 or a s5 tranny... incase they dont know how to tell the bottom pan on the s4 are 10mm and on a s5 12mm..# is 18669406666

good luck

 

for real...my s-afc reads my rpm 400 lower than my stock gauge..

 

Weird, my friends safc reads the exact same as the stock tach.
