Big Boost will be announcing a release and pre-order date next week on a new set of upgraded twin turbos for the S55. We have been told they are stainless investment castings with a 40% larger area in the exhaust turbofold over stock, dual ball bearing and inconel lightweight turbine wheel/shaft. As for power potential, we’re told the compressor wheels will be a billet aluminum for 800-1000 whp or titanium for 1000+ whp.

Perhaps most notably, this fits OEM style downpipes so if you have already invested into after market downpipes that can be re-used. Additionally, they are providing the intakes/chargepipes.
