Max YOUR ND Miata Performance! Each of our ND has over 200 runs on the dyno to test everything from headers to intakes (the headers work, intakes really don't) to superchargers and turbos. It must be noted that the ND has the smartest ECU we have ever seen, and it takes AGGRESSIVE action to protect the motor. That means even slight variations in weather can result in the car pulling timing, and it also pulls timing if the temperatures of the car fluids start to spike. As a practical matter this means we see dyno results vary by 20 hp and more with just a mild shift in the weather, or fuel, or coolant temps, etc. If your dyno work before and after a change does not precisely duplicate weather variables and car temps and fuel you are wasiting your time and producing data that is not meaningful.
I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy
Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
