Important Notes on Your Modular Straight Gate

Turbosmart accepts no responsibility whatsoever for incorrect installation of this product which is potentially hazardous and can cause serious engine damage or personal injury.
Consult your local specialist before setting your desired boost pressure, setting boost beyond your engines capability may result in engine damage.
The Modular Straight gate is designed for use with a turbocharger that does have an internal wastegated that is electronically controlled.
Consult your local specialist before setting your desired boost pressure, setting boost beyond your engines capability may result in engine damage.
Correctly setting up a sensible boost control strategy to ensure engine safety is highly recommended.

Recommendations

Allow for adequate cool airflow around actuator
DO NOT Mount the wastegate so that the top motor housing is less than 100mm from a heat source
Turbosmart recommends that your wastegate is fitted by an appropriately qualified technician.
Turbosmart recommends that the engines Air/Fuel ratio is checked while setting the desired boost pressure, as any increase in boost pressure can cause the engine to run “LEAN”, resulting in possible engine damage.
Turbosmart recommends that boost pressure is set using a dynamometer and not on public roads.
Turbosmart recommends that a boost gauge be permanently fitted to the vehicle.

FITTING YOUR ACTUATORLESS WASTEGATE

Mounting your New Turbosmart Modular Straightgate

Slide the actuator head through the turbocharger mounting bracket. Once mounted on the bracket, secure bolts to hold actuator in place. These are located in the box. It's recommended to leave nut on the shaft to hold the position roughly of the home position which will be matched up later.

CAUTION! Ensure all nuts are bolt are tightened up after final fit up.

Install Actuator through bracket

Using the supplied hardware mount the actuator and rod onto the modular straight gate adaptor.

Actuator secured onto bracket

It's important to test the calibration before attaching the wastegate to the car, this will allow us to test the calibration before being unable to see the position of the valve.

Applying Actuator Preload / Ensuring Wastegate Flap is Closed

CAUTION! This step is important

In order to ensure the actuator does not suffer any stiction/temperature creep issues or the wastegate flap does not stay slightly open, it is important to apply a small amount (1mm/0.039”) of preload to the wastegate actuator. Understanding of the OEM specifications on calibrating and setup required to mount the actuator. In the case below the rod is completely in the home position. The straight gate too is in the close position. Allowing these too be matched allows for clabritation to be intialised. Following the manufacture's guidelines is important.

Closed position

This step is important, it's required to allow the modular gate to work correctly. With the electronic wastegate in its home position. Matching the straight gate valve to this position should allow for calibration to start.

Open position

To apply 1mm/0.039” preload, simply turn the adjuster nut 1 full turn in the clockwise direction.

To lock the actuator in this position, turn the locking nut by hand until finger tight, then proceed to tighten nut firmly to secure actuator in place. (6.5Nm / 4.8 ft lb)

Start Engine and Check for Leaks

Congratulations, your Modular Straight gate is installed and ready for use. Double check all fittings, lines and mountings then proceed to start engine and check for leaks.

FITTING YOUR MODULAR WASTEGATE

Mounting your new Turbosmart Modular Straight Wastegate

The weld flanges should be welded to your exhaust system. The weld flanges are compatible with Stainless Steel and Mild steel welding rod material.

For best results, an attempt should be made, if space allows, to mount the Straight Gate at an angle to the exhaust flow to allow for better flow than a 90-degree mounting. See the schematic diagrams below for examples of mounting positions.

(Best Flow) Symmetric mounting allows an excellent flow of exhaust to the Straight Gate

(Good Flow) Angle mounting allows a good flow of exhaust flow to the Straight Gate.

(Poor Flow) 90 Degree mounting gives poor exhaust flow to the Straight Gate and in some circumstances may contribute to over boosting.

Not Recommended - Less than 90 Degree Mounting. An angle mounting as shown in not recommended and gives extremely

poor exhaust flow to the Straight Gate which can contribute to poor boost control and over boosting.

Caution Do not place the modular straight gate near a significant heat source as this could shorten the life of the internal electronics

Fitting the Modular StraightGate

Prior to mounting the Straight Gate, place v-band over weld on flange by unscrewing the nut on the v-band as far out as possible and then squeezing the bolt in a syringe motion to expand the v-band (squeeze the dots together below). Once the v-band is in its fully expanded position, slide the v-band over the flange to allow for the wastegate to be installed.

Using the 3/8” deep socket and a torque wrench Tighten the V-Band to 7N.m (5 ft/lbs). Ensure the wastegate is home correctly while torquing the nut to not have a false torque as this will likely contribute to exhaust leaks.

Torque should be rechecked after a heat cycle.

Clocking Modular Straight Gate

The actuator can be removed and rotated through 3 different orientations; these are every 120 degrees. The actuator 3 x M5 Allen bolts that lock the body to the actuator. It may be required to remove the snap ring ensuring not to lose it.. Once these are removed the actuator can be rotated to two other positions of the three.

TROUBLESHOOTING

Wastegate not actuating - Confirm electrical connector is plugged in.
Poor wastegate actuation – Confirm no obstructions in actuator rod path.
Boost creeping at high rpm - Wastegate flow path is poor, wastegate is too small for the application, ensure ball joint is not seized
Failing the above, submit a technical request form with information about your engine, oil type and photos of the installation and our expert technicians will respond as soon as possible.
