LSA powered cars traditionally suffer from lag or hesitation off boost when first applying throttle. Instant Throttle Response is created by the Venturi effect top shape of the XAIR OTR Body combined with the large oversized Green Filter. A massive voluime of Cold Air from in front of the Car is rammed/sucked straight through the filter then channelled directly up and around the curved top section creating a Venturi effect and forcing its way into the Throttle Body.
The XAIR OTR has the largest air filter panel on the market, the filter size is 460mm x 180mm which provides more Air Flow than even the biggest Pod Filters as well as supplying much cooler air from in front of the car compared to the superheated air from within the engine bay from the traditional Intake location. Extensive testing and research has proven that the larger the Filter area, the less restriction & servicing required. Outlet Dimensions are 96mm internal diameter, 108mm outer diameter for the Plastic and 100mm internal diameter, 106mm outer diameter for the Gloss Black and Carbon
The filter brand is Green Filter Europe - Custom Made for XAIR and known to be one of the best in the world (as used on World Rally Cars) and proven to flow substantially more than other brands such as K&N etc. In 99% of applications the Green Filters do not require re-oiling, simply wash with warm soapy water every standard 10,000km or 15,000km Service! Guaranteed for 100,000km!
Designed to incorporate/run with the Factory MAF Pipe Element located in place in our custom attachment hose. VF LSA Kit comes complete with Hose Attachment, breather line attachment fitting and Powercoated Brackets to Tilt the Radiator Back.
Note : We utilise the Factory MAF which is removed from the Standard Intake Pipe and is then installed straight into our attachment Hose. However because of the Throttle Body and MAF Pipe angles combined with the MAF being so close to the throttle body we've found a lot of the LSA cars suffer from Reversion so a full Custom Mafless (Speed Density) Tune is recommended.
Note : For Chevy SS Cars running Auto Transmission with LSA Conversion you will need the Low Profile Heat Exchanger Adaptor Bracket
On a standard car we are seeing Gains of 35-40kw when bolted on and Custom Mafless Tuned.
PRODUCT TESTING
Initial test Car was a 2014 Auto Gen F HSV GTS. On the stock Power Run on the Dyno it made 318.9 rwkw (415kw at Engine). With XAIR OTR Bolted on and no other Mods it made 336.4 rwkw (437 kw at Engine).
Our next Test Car was a 2016 Auto Gen F2 HSV LSA R8 Test car, Dyno Sheet shows 3 runs,
1) Stock Car - 296kw at the rear wheels (384kw at Engine),
2) XAIR LSA STAGE 1 - LSA OTR Cold Air Intake & Overdriven Crank Pulley with Dyno Tune - 365kw at rear wheels (475kw at Engine),
3) XAIR LSA STAGE 2 - LSA OTR Cold Air Intake, Overdriven Crank Pulley, 1.7/8" Primary Headers, High Flow Cats, Twin 3" Exhaust with Dyno Tune - 412kw at rear wheels (535kw at Engine) - We tuned it to the absolute maximum to see what sort of Power we could extract - see above video for this max power dyno run. For the final tune we brought the power back to just over 400kw at the rear wheels (520kw at the Engine)
LSA ECU TUNING
The X-Air High Flow OTRCAI Body has been designed to create a Venturi effect and Ram Cold Air in. Combined with the High Flow Green Filter this means that your car is receiving a lot more volume of cold air than was ever intended.
With the OTR installed because of the Throttle Body and MAF Pipe angles combined with the Factory Maf Pipe being so close to the throttle body we've found the LSA cars suffer from Reversion when the throttle snaps open and shut. For this reason we recommend a custom Mafless Tune be done by a reputable Tuning company. This combined with the XAIR LSA OTR will improve power and throttle response dramatically from standard.
REPLACEMENT FILTER / CLEANING KIT
Depending on driving conditions (exposure to dirt/debris/mud etc) with regular cleaning the XAIR OTR Green Filter should last up to 100000km. Order Replacement Green Filters and Cleaning Kits Separately.
