Gray Ice Coating

Twin Turbo System

       CAD designed, high content nickel alloy ductile iron manifolds (machined to your kit specifications,  LS3 or LS7).


Chromex finish (polish) or

Satin (choice of  6)

[Withstands exhaust temperatures up to 2000 F degrees.]

Manifold Design:

  • Turbo placement above the oil level allows gravity drain into the oil pan. CNC cut the flanges and weld ½ mandrel bent tubing for the oil drains.
  • Oil drains fastened to the brass pan inserts using high grade/temperature silicone couplers. The oil feed lines are -3 stainless hose with stainless fittings.
  • Two T3/T4 Turbonetics custom turbochargers.

Patented ceramic ball bearing technology

       Turbonetics ceramic ball bearing turbochargers utilize an angular contact ball bearing with silicone-nitride ceramic balls. Yeah, yeah, it sounds fancy but what does this mean? It means that our unit can withstand between 1000 to 2200 lbs of dynamic thrust load vs. conventional unit’s 60 to 80 lbs.

        Turbonetics uses a single ball bearing instead of two, BY DESIGN. The angular contact bearing is the loading surface! The turbine-end bushing bearing acts as a shock absorber to prevent destructive rotating imbalances. The imbalance can damage the turbocharger from inside out. Through computerized modeling and high-speed rotor dynamic analysis, the floating turbine end bearing was found to be the very best way to absorb and dampen critical frequencies that are transmitted through the turbine shaft. On top of all this, Turbonetics design allows the unit to be rebuilt. Try finding a source that will totally rebuild a typical “dual ball bearing” setup. You will get the same answer every time – “buy a new cartridge”.

        The downpipes are mandrel bent, tig welded, and argon purged, 2-1/2”and bolt up to your stock exhaust system with optional high-flow catalytic converters. Each wastegate discharge is reticulated back into the exhaust leaving you with the quickest and quietest wastegate discharge possible. TTi was the first to use the internally gated turbine housing for an externally gated system. Like the manifolds, a chromex polish finish or any of our satin finishes are available on the turbine down pipes and wastegated discharge pipes. Wastegates come in two different brands to suit your needs, either a 38mm Turbonetics Evolution or a Tial 38mm. Either one will hold your selected boost level. A smooth transition gets you the velocity needed for instant boost response.

       As the air flows from the polished compressor housing, to the inlets of our enormous bar & plate intercooler, the intercooler ducting steps up from 2” to 2-1/2”. Each piece of intercoolered charge ducting comes with a bead rolled end to ensure you’re never left on the side of the road with a blown charge pipe

       All intercooler ducting is manufactured from mandrel bent aluminized tubing, allowing us to deliver over 1000CFM of turbocharged air with no lag. On each custom Turbonetics compressor cover is a welded 90 degree cast aluminum elbow that out flows the average silicone coupler. Our industry leading, 2ply, silicone couplers are fastened by 360 degree lined stainless steel clamps, promising a air tight seal.

         Our Stage X intercooler measures in at over 27” long which is 33% larger over our dual intercooler setup on our previous system and utilizes 2 custom cast aluminum end tanks & one 3” x 3” x 3” hand made sheet metal aluminum end tank. On the left side of the intercooler, we adapted a CNC machined 50mm Tial bypass valve flanged that relieves any chance of compressor surge. Between the gigantic 3-1/2” bead rolled outlet of the intercooler and the throttle body, is the last the ceramic coated intercooler pipe. Z06 models have a CNC cut MAF flange to guarantee a stock finish and ease of installation fastened by 360 degree lined stainless steel clamps, promising a air tight seal.
