    i dont know what the actual speed was, but i have maxed out 5th gear at 7500 rpm. calculated by the speedo it should have been 150-155mph, but the speedo is a bit inaccurate that high from what i have heard. i need to actually data log it once.

    The JRSC won't make any difference to the top speed, the K-pro might. Our cars are redline limited as far as top speed goes. At stock redline the top speed is approximately 134. With K-pro its going to depend on what you raise your rev limit too.

    Yes, stock the EP fuel cut is at 6800 if I recall correctly. With K-pro it is changable.

    Speedometer. In the EP it is notorious for being a little innacurate at high speeds. People have reported seeing the speedometer go over 140 on a stock EP but that is due to its innacuracy.

    agreed.. i was with my friend when he hit 145 on the speedo... i didn't think it was possible for it to go that fast... especially considering that all he had was intake and exhaust.

    with the rev limiter set at 7700 (kpro), stock trans, and a 215/45/17, your top speed will be about 160 mph

    that depends on the tire size. with stock tires, the speedo is a couple mph optimistic. seems to be the most accurate with a 215/45/17, which is a touch taller than stock.
