It's the VMP TVS that Roush Stage 3 and 427R owners have been waiting for! As they say, "Dynamite comes in small packages". M90 supercharger owners know that there was only so much they could get out of that blower. So, VMP and the engineering team set out to create a package that was a direct, bolt on replacement for the M90, knowing that the key to greater output was greater input. That's why so much attention was paid to the porting of the massive inlet area. This baby can breathe! Couple it with a VMP Port Matched high flow elbow and you're ready to rock. We have elbows that accept both stock GT throttle bodies as well as GT500 bolt pattern throttle bodies. Pulleys range from 69mm to 85mm for up to 15psi of boost. Smaller sizes available in 8-rib, an OD balancer can be used for even more boost. Up to 250 rwhp gains are possible depending on modifications and boost levels.
Whether you have a factory Roush car or a Mustang GT with the Roush blower added, you will now be able to take advantage of the latest TVS supercharging technology. The VMP 1.9L TVS uses the latest in Q-port inlet design for maximum flow. The higher-efficiency TVS rotorpack is less prone to heat soak than the older generation roots blowers.
To take full advantage of the higher-flow of the TVS supercharger the kit will utilize a driver side inlet and come with all necessary parts.
- 1.9L TVS head unit
- VMP High-Flow inlet elbow with proper vacuum line and PCV line fittings
- 05-09 will receive an open element CAI with 113mm maf and zip tube*
- 2010 already have a drivers side inlet and will re-use the airbox*
- All necessary mounting hardware, vacuum lines, and instructions.
- One pulley of your choice from the drop down menu above (use same pulley as Roush/VMP 5.0L)
*2010 RS3 already uses a driver side inlet, the factory ram-air airbox is retained, this will reduce the upgrade cost. The factory intake flows well and is a true cold-air that pulls from the grill area. Aftermarket intakes like the Roush-421529 may be used if so desired.
The stock dual 55mm throttle body is re-used, the kit will support the use of the of the stock bolt pattern FRPP dual 62mm polished TB M-9926-3v
The blower will be available with pulley sizes ranging from 8psi up to 15psi. 10psi and above a fuel system upgrade is recommend like the VMP Fuel Pump Voltage Booster
The VMP TVS is an upgrade for the following RoushCharger Supercharger kit part numbers: 420112, 420114, 420116, 420023, 402863, 420024, 13106066M90, 13106066M90C
Disclaimer: For 82-85mm pulleys we recommend the stock 75mm idler and stock Roush belt. For 79mm and below we recommend a 90mm idler.

The first test we did was with the TVS and the largest pulley we make (85mm). We ran it with the same tune we had for the M90 with the 2.49 pulley. We made nearly 40RWHP/40RWTQ gain with 1-2 psi less boost! Had this been a stock M90 blower without the pulley upgrade we would have gained over 60RWHP and 60RWTQ. It gets better, if you have a 2010, no tuning and no fuel upgrades are necessary at this extremely low boost level!
Next we installed a VMP Plug and play fuel pump booster along with a 75mm pulley. We are still using the stock Roush 38lb injectors. This set is under 500rwhp and very safe for a stock motor that is under 50,000 miles.
For our final stock motor test we upgraded to a GT500 TB and went down one size on the pulley to a 72mm, wow, only recommended for low mileage engines!
