We are the 2017 Super Lap Battle Unlimited RWD champions. We took our Maxxis Supermiata Cup S1 race car and did a quick conversion for this event. We fabricated a crude but effective front splitter the size of Kansas. 10mm Alumalite and some bits of aluminum from Home Depot. Wing was a standard APR GT-1000 we had in the shop. Unlimited RWD allows far more modifications. We frankly didn't think we stood a chance at a podium let alone the outright win against some of the high dollar equipment we were up against. Because of the success of this simple build, we have decided to build an entirely new car from the ground up to take full advantage of the rules for 2018.

This is our winning lap of 1:44.983. This is the fastest a Miata has ever gone at this track by several seconds. A few weeks later we went back with stiffer springs and older tires, did a 1:44.69. This is about 1.5s shy of the Porsche GT3 cup car record on this track.

BP4W stock head, forged everything. Same flow as a stock engine, just more robust.

That's about it. Not exotic, just very well balanced and easy for the driver to extract all its performance potential.

Very nice. You should come over to the Time Attack even Australia has, or maybe we could come to yours.

The $40-50k usd cost to get our butts kicked at WTAC does not represent a good ROI. If you would like to sponsor us however..

That's so true. A ridiculous budget is required to compete in the top tier of WTAC at SMSP.
No chance at WTAC outright win here with 300RWHP. You would need more like 500+.
You would have to beat the Porsche time by about 10 seconds to consider winning open class in World time attack here.

The only cars to have gone faster around SMSP than the fastest Time attack car are the defunct A1GP cars and Red Bull RB7 Formula 1 car.
Only some other Open Wheel categories come close.

Awesome news, really enjoyed the walk around on youtube. Glad all the R&D has paid off.
