Turbo, Supercharger & Nitrous Installs Done Right
Boost or bottle, single turbo or twins — Wisco Speed & Performance installs, plumbs, wires, and tunes power adders for GM and Ford performance vehicles. Every setup is proven on our in-house dyno before you get the keys.
Forced Induction & Nitrous Specialists
The Fastest Route to Serious Horsepower
A well-built engine is the foundation — a power adder is what puts it over the top. At Wisco Speed & Performance in Rosendale, WI, we handle the complete job: the turbo kit, supercharger package, or nitrous system, plus the fuel system, intercooling, plumbing, wiring, and supporting hardware the combination actually needs to survive. Then we tune it on our in-house dyno so the power is real, repeatable, and safe.
We work across the GM and Ford performance world — blown LT muscle, boosted Coyotes, nitrous-fed strokers — and we're honest about what your goal requires before a single part is ordered. The install, the supporting mods, and the tune all happen in the same building, so one set of hands is accountable for the whole combination.
Boost · 01
Supercharger Installs & Tuning
Instant throttle response, linear power, and a whine that announces itself — a supercharger is the power adder for drivers who want boost from idle. We install and tune positive-displacement and centrifugal supercharger packages across the GM and Ford lineups: LSA and LT4 swaps and upgrades, and blower kits on LS and Coyote engines.
- Complete blower installs — GM LS/LT & Ford Coyote platforms
- Factory blower upgrades — LSA & LT4 packages, pulley & heat exchanger upgrades
- Fuel & cooling done right — injectors, pumps & intercooling matched to the goal
- In-house dyno tune — the whole combination proven before delivery

Turbo & Twin-Turbo Installs
Nothing moves the horsepower needle like a properly executed turbo system. From single-turbo street setups to full turbo conversions, we build systems that make big power without giving up drivability. Boosted LS and LT platforms, forced-induction Coyotes — this is the work our shop is known for.
- Single & turbo kit installs — complete plumbing, intercooling & oiling
- Power-adder conversions — like nitrous-to-turbo on LSA platforms
- Supporting mods scoped up front — fuel system, drivetrain, forged internals & cooling
- Tuned and verified in-house — boost, fueling & timing dialed on our dyno

Nitrous System Installs & Setup
Dollar for dollar, nothing adds horsepower like nitrous — and nothing punishes a sloppy install faster. We set up wet and dry systems the right way: proper jetting for the combination, fuel supply that keeps up, window switches and safeties wired correctly, and a tune that keeps the extra cylinder pressure from becoming an expensive lesson. Whether it's a street car with a 100 shot or a drag build leaning on the bottle every pass, the system gets sized and set up for how you actually run it.
- Wet & dry system installs — plate and direct-port setups
- Jetting matched to the engine — honest advice on what your bottom end can take
- Safeties wired in — window switches, purge & bottle heater done correctly
- Tuned on our dyno — timing & fueling verified on the spray, not guessed
