seeing as that thing makes 130 hp, and has a posted top speed of 121 mph, you haven't hit 144, trust me.

e30 speedos are notoriously inaccurate at higher speeds, and I'm sure those yo-boy wheels you have on there probably aren't at the correct tire profile size, so that will just compound the fact.

I clocked my car with a cop buddy of mine who was off duty with his radar gun, and found that at 120, I was 9 mph high, and at 125, 11mph high on the speedo. This is with stock wheel & tire size.
