The new VTDA is a compact, Velocity Tuned intake, designed as an alternate to those wanting more intake sound but still want to retain some temp controls.The standard configuration is insulated though uninsulated can be specified depending on preference. No hoses are necessary with this box though a fresh air feed will improve breathing and temps. Fits all 1.8T transverse engines as well as the 3.2 on TT's and R32's. (Sorry, No A4 or longitudinal fitment available)

The VTDA is a slightly different approach to intakes. Different from Most on the market, but retains some similarities to the TTDA. Construction is similar. Powdercoated or stainless over Microseam Phenolic tubing. It is open ended, terminating in a 4" Velocity Stack style inlet The tube is Smaller in diameter (6") but longer (9.5").

The inlet is very close to the fender vent, so a majority of the air will be pulled from that area. Since it is not sealed like the TTDA, some engine compartment air will be pulled. Insulation is retained, however, so there is still some heat control, both reflective and absorptive. R14 rated Air Bubble/Foil lined for lightless. 97% efficient at bouncing off reflected heat. Front fresh air feeds can be set up Like this For minimal heat ingestion. Check the temperature Data here: Dattalogging the VTDA

Due to the open ended design, the intake is louder than the TTDA which approaches stock levels for quietness. Noise is never intrusive though. It can best be described as "Breathy". Tubes are Microseam Phenolic, and Powdercoated Galvanized steel or stainless wrapped for a good appearance.

The V-stack inlet is flush mounted and a cone diverter is added to the K&N filter cap to speed air flow into the filter box.

Like previous designs, this can be specified to fit a 180TT/VW, 225TT, or 3.2 TT/R32 with simple adapters. Installation is very simple as no feed hoses are needed. Properly positioned, front feeds could be set up to direct a flow of ambient air to the V-stack opening. A bracket, now standard, makes installation a snap. Click on the install notes above.

9/05: Stealth Bracket added

12/1/05: Now improved with a Stainless backing plate for improved rigidity.

1/06: EDM cut Brushed aluminum universal mounting tang added, improved 6mm stainless hardware with Nylock nut to avoid dropped hardware! Picture

2/06: Either bead blasted (stainless models) or Satin black powdercoat (all black tube models) brackets for improved appearance

2/06: Powdercoat option added. Wrapped, Bead blasted, powdered and Baked. Second coat of clear with certain colors for an elegant, tough finish. Currently available colors here in the various color albums!

'07-'08, Construction methods improved for better durability and heat handling

Based on initial testing on My car, the New VTDA flows better than a TTDA which was no slouch to begin with. The V-Stack design obviously helps in this regard. G/Sec tests show a nice advantage to this design, particularly at higher RPM's. Comparative flow graph can be seen here.

Heat ingestion has been measured and the VTDA should be superior to open element filters and uninsulated brands. There is no intake "Swirling" to disrupt flow as in the BMC intake

On Noise, the intake is louder, but never obnoxious. Due to the shrouding of the filter by the C/F tube, noise can be equated to roughly 1/4 the sound of a loud open element style (P-Flow etc).

With the insulation eliminated it is only slightly louder so there is no real benefit to eliminating it. The Turbo can be heard spooling as well as diverter valve air release. It is more aggressive and "sportier" than the TTDA, particularly at higher RPM's.
