FAQ
Why would I upgrade my factory Diverter or Bypass Valve?
Fundamentally, factory Diverter Valves are built to a price point rather than with performance in mind. At Turbosmart, we want you to have the best performance available. Our upgraded valves are designed to overcome the limitations of factory equipment with improved sealing and valve dynamics. A Turbosmart Upgraded Valve will ensure you have all your available boosts with maximum response.
How does the Turbosmart Valve provide performance benefits?
The Turbsmart Range of direct replacement valves utilises our Unique Boost-Balance Valve Technology, featuring a positive seal O-ring on the Piston Face, and are made from motorsport-proven, hand-assembled billet aluminum. These features ensure the fastest responding valve and incredible boost-holding characteristics in a virtually indestructible valve.
What is the Turbosmart Boost-Balance System?
Our Valves are designed to ’actuate or open’ via a pressure differential rather than relying solely on boost. This means we can run the lightest possible spring for a super-fast response, but it also means both sides of the piston are subjected to the same boost pressure when accelerating and under load. This means, regardless of how much boost you run, Turbosmart Valves will not open unless you want them to! You have all your boost pushing it closed at any point in time, PLUS the spring itself!
What is the Turbosmart Positive Seal O-Ring, and why does it matter?
As mentioned above, due to our Boost-Balance technology, the piston of Turbosmart valves is constantly being pushed into the valve seat when accelerating and under load. Turbosmart valves use a Viton O-ring on the face of the valve, which ensures the best possible seal against the body. This seal means maximum boost pressure at all times & improves boost response.
Can I Vacuum or Smoke test my Kompact Valve?
You can vacuum test these valves. However, you will need a high-flowing mechanical vacuum pump – you cannot use a hand-actuated vacuum pump as these do not replicate the flow your valve would see when fitted to an engine, meaning you will likely achieve nothing except for a ’False-Positive’ to a leak test. These do not use an O-ring on the side of the piston and are not based on a diaphragm like the OE equipment; instead, the design focus is on sealing, speed, and overall flow. This design and absence of a diaphragm or O-ring also mean you cannot use a smoke test to test or validate a Turbosmart Valve.
How Much Horsepower will these valves handle?
More than you have! Due to the unique Turbosmart Boost-Balance System, you can’t have too much power or boost for the Kompact Range of Vales & at no point will they leak based on ’Too-Much’ anything. The more boost you run, the better they will seal. With that said, highly modified engines may be able to find the limit of how much these valves can bypass when open & this is the only limit. If you’re at this level, you may consider a remote-mounted valve with more flow potential to avoid audible compressor surge. However, at no point will the valve open or vent due to too much boost or power.
Availability & Shipping
Standard Shipping applies to every order — rates are calculated at checkout, with tracking provided once your order ships. Track your order any time at eurospeed.co/pages/track for a live delivery estimate. International delivery is available at checkout, with rates calculated for your location.
Delivery time depends on the product. Most in-stock parts ship within days, while carbon fiber and made-to-order items may require production time before they ship. For the specific timeline on any item, check the Availability & Shipping section on that product’s own page — the guide below covers our general shipping types.
Shipping Overview
Depending on the item, free air freight may be available for select carbon fiber components, with estimated shipping around 1–2 weeks after dispatch. Larger hoods, oversized body components, and certain made-to-order items may require sea freight and longer delivery windows. If timing is important, please contact us at support@eurospeed.co before placing your order.
Shipping Coverage
EuroSpeed ships to customers across the United States and internationally. Shipping is included in the price of eligible products for your convenience and covers the initial cost of delivery to your destination.
Import duties, taxes, clearance fees, or customs charges required by your destination country are not included and remain the recipient’s responsibility.
Order Processing & Fulfillment
Every order is reviewed, processed, and prepared before shipment. Most in-stock products are processed within 1–3 business days, though some orders may take up to 5 business days depending on fulfillment location, product type, order volume, or courier pickup timing.
EuroSpeed stocks select high-demand products at our U.S. facility and international fulfillment centers. Because our catalog includes many vehicle-specific and specialty parts, not every product is held in-house at all times.
Some orders may ship through our trusted fulfillment network, which may include verified manufacturing partners, authorized distributors, regional warehouses, and international fulfillment centers.
- Orders may ship from a U.S. warehouse, international warehouse, manufacturer, or authorized fulfillment partner.
- Some products may require additional handling, processing, production, or quality-check time before shipment.
- Orders enter fulfillment shortly after being placed and may no longer be eligible for cancellation once processing, production, or shipment preparation begins.
Custom, Made-To-Order & Oversized Items
Custom, made-to-order, and oversized product categories may include carbon fiber steering wheels, hoods, trunk lids, fenders, front lips, splitters, side skirts, diffusers, bumpers, body kits, widebody components, select spoilers, rear wings, and other large carbon fiber components.
Many carbon fiber items are made to order. Some products may already be stocked and ready to dispatch when available, but if inventory is unavailable, your purchase reserves the next available production slot instead of waiting for a separate restock listing.
Production time: Production can take 1–4 weeks depending on product type, selected options, finish, current queue, and quality-control timing.
Shipping time: Shipping can take 2–10 weeks depending on item size, freight method, destination, customs processing, carrier delays, warehouse transfers, and final delivery location. Carbon fiber steering wheels typically ship faster, with shipping usually taking 3–7 business days after dispatch.
By purchasing custom, made-to-order, or oversized items, you acknowledge and accept the extended production, fulfillment, and shipping timelines associated with these products.
Tracking Updates & Delays
All orders receive a tracking number once generated by the courier. Tracking may take 2–3 business days after dispatch to show movement in the courier’s system.
Certain international, oversized, or freight shipments may show limited updates during transfer between fulfillment locations, warehouses, customs, or final-mile carriers. In some cases, tracking is provided or begins updating once the item reaches a regional warehouse, local carrier, or final delivery network.
Shipping timelines are estimates and are not guaranteed. Delays caused by high order volume, weather conditions, customs inspections, carrier disruptions, production queues, warehouse transfers, holidays, or other external factors may occur and are outside of EuroSpeed’s direct control. These delays do not qualify for cancellations or refunds unless the carrier officially marks the package as lost.
