For those anxiously waiting for the production release of the HTV1320-LSJ, we are proud to announce the product is available. As many of you are already aware, from the buzz in the www.cobaltss.net and www.redlineforums.com forums, the HTV1320-LSJ that has been under development for the past 12 months but has now completed it final testing and analysis, and is ready for YOUR Cobalt SS or Saturn Red Line. Harrop wants all users to be well-informed of the performance advantages of the HTV1320 supercharger. This upgraded supercharger is larger then the production equipped M62 it replaces (1.3L vs. 1.0L) and a great deal more efficient. Modified engines will certainly be able to take advantage of the benefits offered from the HTV1320-LSJ.

Further features of the HTV1320-LSJ include:

Eaton's latest TVS technology in supercharging.
Bolt-on solution for the 2.0L.
No adapters required, simply remove the production M62 and replace it with the HTV1320-LSJ.
Interchangeable pulleys - shipped with an 80mm/3.1" diameter pulley. Alternative diameters will be available upon request.
Designed for the higher-flowing LS4 throttle body, but the original throttle body will also fit.
Powder-coat finish is standard.
Service free the HTV1320-LSJ superchargers are OE-quality. The supercharger is a sealed unit that requires no maintenance other than typical OE-style checks.

Although the HTV1320-LSJ is mechanically a bolt-on solution, re-calibration of the ECU and any ancillary items will need to be addressed (upgraded fuel system/injectors etc). Contact your installer/tuner for full details.
