Full-Race is proud to release the T4 twinscroll F1-35R.

Turbonetics has filled the void for a Twinscroll 35R turbocharger. Using the highly efficient twin scroll turbine housing design with the highly acclaimed F1 turbine wheel and 56 trim 61mm compressor allows the turbo to spool sooner, make more low end, more midrange and top end power than a standard singlescroll 35R. In addition, Turbonetics backs this unit with their 1 year No-Fault/No-Hassle warranty.

Until now, the only way to build a Twinscroll 35R was by using a one-off turbine housing intended for diesel tractor use. This housing is not available in North America, and it is almost impossible to get internationally. Also, it is not a true t4 inlet as the openings are much smaller. As a result, if a GT35R was to be used, it had to be singlescroll. After receiving input from many of our road race and drift competitors it was clear that they needed better response, earlier spool and more lowend/midrange power than a standard 35R could offer.

Turbonetics' solution to this was to use 35R wheels in a T4 turbo, allowing it to utilize any of their traditional twinscroll T4 turbine housings AND a true T4 inlet
