That's my buddy's time-attack build. He owns a local shop that handles track prep for all kinds of cars. We all own and race miatas together in WRL and NASA, in addition to the typical Porsche DE stuff.
Our WRL team names are Winning Formula and Le Formua de Winning.....lol. We are Porsche guys, so if anybody is ever at a WRL race, come say hello to a fellow RL'er….
A 600hp, 2200lb miata is crazy fast, it's a tick faster than my GT3 on Pirelli DH takeoffs, and is getting even more power this offseason.

245 to 275 size slicks typically
That's easy to do. That same weekend I turned some 2:07's and could easily get into the 6's with fresher tires, clean laps, and different brake pads. I was having way too much ABS jump in from the Ferodo DS1.11....they just don't offer the control needed when you are trying to really wring out every last bit. I was unofficially racing him for lap battle honors, but you tend to not "send it" quite as aggressively through T5 and T16 when you are in a 150K car that you have to drive home in.
The car would certainly do 2:05's with a little more setup and open laps like they had. I had to run my laps in the DE sessions, not the time attack sessions, so a bit more traffic.
Was turning 2:11-12's on stock Cup2 tires. Car will do 2:10 or perhaps lower on Trofeo-R. I'll get some data in March.
Sadly, the V8 miata will be getting more power and less weight, so I won't be able to touch it come next year in terms of pace. Next year that car will be in GT2RS performance land......

Here's another video of us lapping at Putnam together. No clean laps, but we both turn 1:11's in traffic, which illustrates the pace of both cars. We both turned 2:09's earlier in the day.....the cars are actually pretty evenly matched, he has better high speed aero and GT3 is better under brakes. 2nd gear corners favor the GT3 a little bit too.

Will be fully caged soon. It was a street car that turned into an engineering exercise to support three other customer V8 swap projects, then morphed into a full on time-attack style car, and now will be fully caged with a new motor. It wasn't until one of our WRL team's co-drivers engineered and now sells a heavy-duty front wheel bearing/hub assembly that can take the stresses, that the car could see enough track time to even see what it could do. Now that it can keep a wheel bearing underneath it, he can now cage it and drive it more. Otherwise, it would nuke a factory style wheel bearing in a couple 20 minute session on slicks.
The biggest issues the V8 swap faced were oiling at high-g loads (custom dry sump), brakes big enough to handle those speeds (Stoptech calipers and rotors), and wheel bearings (custom HD wheel bearings).
While these types of projects are cool, it also makes me also appreciate the durability of the GT3. You can lap a GT3 all day long in 90 deg. temps and it just keeps taking the abuse. That's the difference between a small street car modified to be as fast as a GT3, and a car engineered from the ground up to be a street car for the track and race car.
