I noticed that the stock tach is not very accurate, just driving around town, it seems sluggish to move. But are you sure its that off?

it prolly varies car to car

Dear Lee,



HOW DO YOU KNOWWWWW?????????????????? hahhaa https://www.nopistons.com/forums/pub...1047683785.gif

WHAT!?!?! The tach is off. I'm going to verify it with an aftermarket, and then compensate with my driving TRUE 7,500 RPM's here I come https://www.nopistons.com/forums/pub...1047683473.gif

driftin at the track, spun out, slammed it down into 1st and held a burnout as everyone else went by me.



lsd unloaded into a one wheel peel, all of the sudden is was around 8 and bouncin off the limiter, i was like oh **** and let off, and bang, big backfire. scared the **** out of me.

when alex pheiffer drove my 1st gen @ thunderhill, he'd pitch it over turn 5, and hit the gas tach would be pegged @8k and you could still hear the engine revving.... s4 block btw

so on a stock s4 you can rev the motor out to 7k safely? i have an intake thats it but never really push my car past 4.5rpms? would that hurt it ?

holy babied s4 batman, sell me your car.

you're actually doing a disservice by not visiting the redline at least once in a while. a trip to redline helps get rid of damaging carbon deposits and keeps everything moving properly.



a redline a day keeps the mechanic away.

So what, the actual rev limiter is at 8100rpm? If you ported it and modified it to suit, but kept standard ECU (if that's possible) it would therefore happily pull to 8100rpm then limiter itself? Sounds good...
