in my 94 dx, when i go for a top speed run, i top out at 121 it says on the speedometer, now i do have 15 inch wheels with 195/50/15s so i wanted to know if the speedo was off. i did race my friend with a berretta, bone stock and when he was at 115 i was at 110. all the top speeds i have researched and people i have talked to say that the top speed is around 110. so is mine that far off???

please help cause its really bugging me

 

I'm sure it's off. I went from the stock 185/65/14" tires to 195/55/15's and now it is off by 5mph at most speeds. At higher speeds it's even more off.

i did the calculator thing and its not off by much, like .3 or something like that. well does anybody have a dx civic (92-95) that could tell me what their top speed is???

 

93 dx hatch, b18b. topped out at 130-133mph

 

sweet (130 mph) but i wanted to know what everybody gets to in the d15b7 motor thanks guys

 

118-121 mph depending on how far off the speedo is. The speedlimiter is at 116 mph.

By changing to a Si/EX gearbox and ECU (even with CEL's) 128 mph is possible in 4th gear, but that was 3 years ago!
