  • Supermiata S1

    For 2017 we have added the turbocharged S1. S1 adds a Trackspeed Engineering EFR6258 turbo kit, big wing, splitter, 6 spd trans, 15x10 wheels shod with Maxxis RC-1 245/40/15 and allowances for more creative cooling mods up front.
    S1 builds crossover to NASA ST4 almost directly. Turn the boost up a bit for ST3 or ST2. ST4 seems to have the best fields. Currently 6 cars built for S1, more on the way. S1's are about 10s faster than Spec Miata lap records.
    220whp regulated max power, 2300#

    Why did you decide to go with VR-1s instead of RC-1s?

      At 10sec faster than SM what are you doing about brakes?

        There's also a spec BBK for the class.

          They are a lot faster when you can't slow down for the turns. ;-)

              Not spec brakes but we do have some cost containment features.

              Any Wilwood caliper in front, 11.75" max rotor diameter. Iron rotor only. Rear brakes can be 2 piece rotors but must use OEM calipers. Beyond that it's free.\
              Plenty of brakes.

                I thought that might be the case but with Spec Corvette running a street tire I figured VR-1 wasn't entirely out of the question.

                  You guys have done an excellent job with supermiata. The cars look racy. That's how a miata should look.

                    That was carefully considered during the development. Can't just be fast, they have to look fast too

                      S1 race at ACS 11/5/17

                      This is from race 1 last Sunday. After the quick SuperSprint we reform and invert grid on the cooldown lap then run another SuperSprint. This is the format both days with initial grid being set by individual qualifying Saturday morning.
                      Andrew and I had a good battle. His car was a bit freer, getting a bit better mid corner grip. Mine set up tighter so tippy toe mid corner but coming off turns much better. At ACS, my set up proved more raceable and quicker. At a more turn-y track like Buttonwillow or Chuckwalla, I think his set up would be better.
                      We did high 1:48's in the race, 65 ambient. That without an ACS specific setup which we were all too lazy/busy to do. That would mean lower ride height, lower splitter, a bit of wedge, car tilted to left, more RF camber, no Gurney flap. Probably worth .7 to 1.0s if we did that.

                      The cars don't have huge top end speed because of the relatively wide tires and aero but they launch off low and mid speed turns like a rocket. They drive like the S2's just a bunch faster. I find myself taking more of a "V" line in some turns. So instead of going in super hot and looking for highest min corner speed I overslow maybe 1-2mph to rotate more mid turn so I can line up the exit and get back to WOT sooner.
                      Sort of the same thing you do in grip limited cars with a lot of power. Not that the S1's are severely grip limited, just that they launch off the turns so well.

                      Our initial setup plan proved to be spot on. The cars have a perfect balance between stability, agility, power, brakes, aero and mechanical grip. A very natural and intuitive feel. Easy to drive once you calibrate yourself for the speeds. Those coming from faster cars will find them easy to drive at the limit. Those coming form lower powered cars might need a few weekends to get used to the power over steer available through the top of 4th gear.
                      But that's a good thing. A very good thing.

                        S1 battle at WSIR

                        William and I had a great battle in Race 1 this last weekend. Started P2, fought my way into the lead. Had some transmission troubles which dropped me back to 4th. Trans came back to life so I chased my way back to get 2nd right at the line.
                        Diving into the lapped Spec Corvette in T9 while fighting for postion on the last lap was ah, memorable. A little rubbing with William's car along the way
                        Short but intense race!
