At Noonan Ultimate Race Engineering, we put the racer first. We consider ourselves partners in our clients’ success. We plan together, race together – and when our award-winning race engine components deliver the champion’s trophy, we celebrate together. Each and every Noonan product comes with an unmistakable stamp of quality, bringing to skilled racers high-performance equipment tailored to their needs.
For NHRA turbo racers concerned by the revised valve size ruling of 2015, we’ve thrown all our resources at developing this Promod Turbo cylinder head that’s fully NHRA-approved and meets the new regulations without sacrificing any horsepower or packing on any excess weight.
All Noonan cylinder heads are manufactured from high-quality tempered billet material for outstanding durability in a light, economical package and finished with 3D CNC machined contouring for our signature sleek look.
We aren’t just interested in providing quality you can feel. We’re fully invested in providing quality that lasts. Time after time, race after race, Noonan’s turbo cylinder heads deliver consistent, race-winning results. That’s down to the resilience of our fully billeted products.
Durability-enhancing features of the Promod Turbo include spring oilers for demonstrable improvements to spring durability and deck-faced O-Ring and valve cover O-Rings for tighter gasket seal without silicone sealants. With the ability to accommodate 9/16” push rods, racers will have no trouble customising the Promod Turbo for maximum longevity in even the most punishing race conditions.
We also offer the useful option of installing Drain Back Drillings to suit late-model blocks. This painstaking process reduces oil retention in the top end of the motor, enabling oil to be returned to the sump or tank for more economical and reliable performance.
We’re the first-choice cylinder head manufacturer for heavyweight racers for one reason – we’ll settle for nothing less than the best. And as our track record proves, the best is exactly what you’ll get, with Noonan Racing.
