Although the 1991 Camaro rs has the potential to be a vrey fast car,the speed is limited to 110 mph by means of a fuel shut off chip located in the dashboard.

Answeri have replaced the stock chip(extremely easy to do)with a chip from eBay which removes the speed limiter.that let me hit 145 on a flat freeway with two over weight passengers and a bunch of camping gear.probably about 500 extra pounds.i then replaced the stock manifolds with pace setter shorty headers and a high flow y-pipe.i welded a Flowmaster super 40 series muffler directly to the end of the y-pipe(sounds amazing).i removed all stock emissions and topped it with a k&n filter.i replaced the stock speedomiter with an aftermarket 220 mph speedo and changed the speedo gear to match my 18" panthers.after all that my tranny went out so i bought a monster 700r4 off eBay with a 2200 stall.the speedo was checked for accuracy and i went out for a top speed run.it reached 165 real quick and slowly climbed to 175 and was done.i have the 305 ci v-8 and tbi. so for almost $3000 i gained 65 mph on the top end. it was pretty impressive for an all stock block and rear end.PLEASE DO NOT ATTEMPT THIS ON THE STREET,ITS NOT SMART AND I SHOULD SMACK MYSELF FOR DOIN IT. AnswerI have a completely stock 5.0L 305 v8 91 Camaro R/S, haven't done anything to it other than regular tune ups. Couldn't tell you the exact top speed cause the speedometer doesn't go high enough but there is no fuel shut off in mine. I've had the needle completely buried on many occasions and it was still gaining speed. I'd say at least 130mph but could more
