Performance Builds & Dyno Testing in Ellensburg
Complete performance builds for gas and diesel vehicles, planned as one combination and verified with Dyno Testing in our own shop.
Big builds go best with one shop planning the whole combination. Whether it is a high-horsepower Corvette or gas performance car, a lifted diesel truck or a serious 4x4, Crossroad Garage in Ellensburg plans the engine, induction, fuel system and drivetrain together, builds engines and transmissions in-house, and checks the results with Dyno Testing.
Built as one combination
Power goals touch every part of the vehicle. We start with how you will use it, what is already installed and your budget, then lay out the build in stages that make sense. Parts are chosen to work together, so you are not buying twice when the next upgrade shows a weak link.
Performance build services
- Engine builds for gas and diesel performance projects, done in-house.
- Forced induction: turbocharger and supercharger upgrades with the supporting parts they need.
- Fuel systems sized for the build: pumps, injectors, lines and filtration.
- Cooling, intake and charge-air upgrades.
- Drivetrain built to handle the power: in-house transmission builds, driveshafts, gears and axles.
- Brakes, wheels and tires matched to the vehicle's new capability.
We are a Texas Speed & Performance dealer for LS cams, cylinder heads and engine parts, and we build and install them in-house.
Dyno Testing
Our chassis dyno lets us measure the vehicle instead of guessing. Dyno Testing is part of how we plan, verify and troubleshoot builds.
- Baseline runs before work starts, so you know where the vehicle stands.
- After-build runs to measure the result of the work.
- Build verification: confirm the combination is running the way it should before it goes back on the road or trail.
- Drivability under load: reproduce and diagnose problems that only show up under real load.
- Dyno sheets for your records, so you have the numbers from your own vehicle.
Diesel, off-road and drivetrain builds
Performance work often connects to our other specialties. See diesel engine builds and repair, diesel transmission builds and repair, off-road builds, lifts and suspension and gears and axles for 4x4s.
Performance build FAQs
Can you build my engine and transmission together?
Yes. We build engines and transmissions in-house, which makes it easier to plan them as one combination.
Can I just get a Dyno Testing session?
Yes. Call to schedule. Tell us the vehicle and what you want to learn from the runs.
Do you work on gas performance cars too?
Yes. We are an Auto & Diesel Performance & Repair shop, and gas builds such as Corvettes are part of our work.
