anyone hear about the jms perfomance package, includes jms CAI, sct tuner, underdrive pulley set, and choice of gear set. With just these mods they ran a 12.4 quarter mile. Just wondering if anyone has used products from this company.
While I agree with your comment in general (careless dyno numbers and et times tossed around for profit), recall that the guys with 400+ rwhp have hella issues hooking up with all that torque at launch. The 1/4 mile times is NOT simply a matter of who much HP you have. For instance, a guy just put on a Saleen blower, and got 430rwhp! Ya know what he did in the 1/4? 13.00. He spun tires through 3 gears.Redfire said:I have a friend that has a 04 Cobra that he has had on the dyno that produced 490hp at the rear wheels and he runs 12.1 in the 1/4 mile and 1.8 60 ft times. He is running 12lbs of boost. I find it hard to beleive that the JMS setup will run 12.4. Just my .02 cents. I am tired of low 1/4 mile times everywhere when they aren't real world numbers.
