hey guys i just bought a 89 hatch si for 500 bucks at an auction andit hauls ass.dont get mad i still love my accord. anyways i was kinda testing out its limits and trying to find out the top speed for each gear and i dont hit the rev limiter. it has a d16a6 engine and the redline on the tach is around 6500. todya i pushed that sucker to about 7500 and the limiter did not kick in. now im wondering if the prior owner chipped the car(it was already lowered and had a custom exhaust ), or is the revlimiter suppose to kick in at a higher rpm. i just dont want to push it more it can handle it. thanks for any help. what should the stock rev limiter kick it at ??
