Rotary Engine Builder • Mazda RX-7 & RX-8 Specialist • Porting & Drag Racing
Forged in Fire — Built to Last
“Average Vlad Dad extraordinare
Rotorhead • Paid Firefighter • Winger of things”
By day, he answers the call — a paid firefighter running toward the flames everyone else runs from. By night and every moment between, he’s deep inside the soul of the Wankel rotary engine, chasing perfection one apex seal at a time.
Puerto Rican born with three decades of rotary mastery, Vladimir has built a reputation that precedes him in every shop, every drag strip, and every rotary community worldwide. From hybrid RX8 builds to full race-spec 20B monsters, his hands have shaped engines that don’t just perform — they dominate.
Every engine that leaves the bench carries the weight of thirty years of obsession, precision, and an uncompromising refusal to cut corners.
Complete rotary engine assembly from teardown to first fire. 13B, 13B-REW, 20B, and Renesis platforms built to exacting tolerances with race-proven methodology.
Pioneering hybrid rotary builds — merging RX8 Renesis internals with RX7 housings for the ultimate power-to-reliability ratio. A signature Impaler specialty.
Half-bridge, full-bridge, and peripheral porting performed with CNC-level precision. Each port profile is matched to the build’s target RPM and power curve.
Rotor balancing to 10,000+ RPM specifications. Every component weighed, measured, and matched. Powder-coated finishes for engines that perform and look immaculate.
Drag-spec and time-attack engine packages. Built for the abuse of forced induction at extreme boost levels. Proven on the strip with teams like LadyBoss Racing.
Hands-on training for the next generation. Teaching the art and science of rotary engine building — because knowledge shared is knowledge multiplied.
“El enfoque siempre es igual — mejorar hoy más que ayer.”The focus is always the same: be better today than yesterday
“Taking pride in your work is not the same as being prideful.”Vladimir Gonzalez
“I’m always investigating to improve the next build. Siempre estoy investigando para mejorar.”The Impaler Method
Every measurement triple-checked. Every seal seated with care. The build is done when it’s right, not when it’s fast.
Unlike builders who hoard trade secrets, Vlad shares openly — documenting techniques, explaining the why, and training the next wave of rotary craftsmen.
Every build is a laboratory. Every engine returned from the track is data. The pursuit of the perfect rotary engine never ends — it only deepens.
From Puerto Rico to worldwide — building a global community of rotary enthusiasts who lift each other up. The competition is with yesterday’s self, not each other.
From street-driven rotaries to full race engines pushing the limits of forced induction. Every project is a testament to precision engineering.
Full 13B-REW rebuild with bridge porting, balanced to 10K RPM. Turblown manifold, Link ECU management. A beast built for the strip.
The Impaler special — RX8 Renesis with RX7 housings.
Half-bridge ported Renesis for max NA response.
Monster motoring. Built and tuned for peak boost.
Race-spec engine for LadyBoss Racing team.
The holy grail of rotary — triple rotor perfection.
