Do you work on all Mopars or just Hellcats?
+

We specialize in the Gen III Hemi platform — Challengers, Chargers, and related vehicles including Scat Packs, Hellcats, and Redeyes. We're focused on the 6.2L and 6.4L performance variants where we can offer the deepest expertise. Not sure if your car qualifies? Just call us and we'll tell you straight.

Can you guarantee specific horsepower numbers or ET times?
+

Honestly? No — and any shop that does is overselling you. Power output and track times are affected by tuning, fuel quality, weather conditions, track prep, and driver. What we can guarantee is quality parts, clean installation, proper supporting mods, and a build spec that's realistic for your goals. We'll set honest expectations before any work begins.

Do you tune in-house?
+

We work with a trusted, experienced tuning partner on every build. We coordinate the entire tuning process — you don't need to source your own tuner or manage that relationship yourself. It's part of how we deliver a complete, finished build.

Whipple or Hellion twin turbo — which is right for my car?
+

It depends on your goals, your budget, and how you use the car. Whipple installs are typically more streetable, respond faster at lower RPM, and integrate cleanly with the factory engine bay. The Hellion twin turbo kit produces strong top-end power and is popular for serious street/strip applications. We'll talk through both in your consultation and make a recommendation based on your specific situation.

How long does a build take?
+

It depends on the scope of work, parts availability, and our current schedule. We give you a realistic timeline estimate before work begins — and we communicate clearly if anything changes. We'd rather be honest about lead times than rush a build.

Can I still daily drive my car after modifications?
+

Most of what we build is designed with real-world use in mind. A car spec'd for the street gets built differently than a dedicated strip car. During your consultation, we'll talk through how you actually use the vehicle and build a package accordingly.

What does E85 conversion involve?
+

A full E85 conversion typically includes upgraded fuel pumps, larger injectors, and a flex fuel kit that allows the car to run on E85, pump gas, or any mix of both. The tune is then calibrated to take advantage of E85's higher octane and better cooling properties. It's one of the highest-value modifications for high-boost applications — more timing, more power, safer at elevated boost levels.

What supporting mods do I need for a big pulley or boost upgrade?
+

At minimum, most significant power upgrades require fuel system work — pumps and injectors that can keep up with the demand. Depending on the power level, you may also need cooling upgrades, upgraded heat exchangers, and a drivetrain assessment to make sure the transmission and driveshaft can handle the load. We won't install big power on a car that isn't ready for it — we'll tell you what's needed before we quote the exciting stuff.

Can I supply my own parts?
+

In some cases, yes — we're happy to discuss this during your consultation. We prefer to source parts ourselves when possible so we can stand behind the quality and compatibility of everything going into the build. If you have parts you'd like to use, let's talk through it before assuming it'll work.

Will modifications void my factory warranty?
+

Performance modifications can affect your factory warranty, and the specifics depend on the modification, the dealership, and the circumstances. This is worth understanding before you start — we're not lawyers and can't give legal advice on warranty matters, but we're happy to talk through what we've seen in practice. Do your own research and understand the Magnuson-Moss Warranty Act if this is a concern.

Do you offer a warranty on your work?
+

We stand behind our installation work. Warranty specifics vary by service and parts — ask us about this during your consultation and we'll be clear about what's covered and what isn't.

How do I get started?
+

Give us a call at (646) 996-8443 or fill out the build request form. Tell us about your car, what you're trying to accomplish, and a rough sense of your budget. We'll set up a no-pressure consultation — no obligation, no sales pitch — and figure out together whether we're the right fit for your build.
