Spool Performance Billet Manifold B58 Top Mount Turbocharger Kit

Spool Performance Billet Manifold B58 Top Mount Turbocharger Kit

Posted by Elyse Cruz on Aug 3rd 2023

"Spool Performance is proud to introduce our one-of-a-kind top mount turbo kit featuring a 5-axis machined billet exhaust manifold. This process has allowed us to create a unique manifold that features ultra short runners providing maximum heat energy retention up-to the turbine while avoiding common issues with cast manifolds like cracking and increased weight. The 5-axis manufacturing process has also allowed us to create an extremely efficient flow by equalizing wastegate port design allowing for excellent boost control with a single 45mm wastegate. The result is a fast spooling and lightweight manifold that delivers almost nonexistent levels of backpressure and is easy to install. The modular nature of the manifold design allows us to offer these kits with a wide variety of turbo options. The kit can be configured with a Spool IFX water cooled ceramic ball bearing or Precision air cooled turbo."

(B58 Spool Performance Manifold)

After countless hours engineering our manifold design, we were able to create an extremely efficient twin scroll flow channel in the 5-axis machined wastegate flow ports that allows for excellent boost control. Our manifold is milled out of high strength steel alloy billet blocks that have minimal heat expansion. Being able to mill the flow paths into the block has allowed us to use short but smooth flow channels up to the turbine housing. This retains maximum heat energy and reduces turbulent flow energy losses in the system allowing for a faster spool and ultra-low backpressures at higher engine speeds. The modular design has also allowed us to create variations quickly to allow for a variety of turbocharger options. 

(Wastegate Design)

The wastegate flow ports are one of the most overlooked but critical components of a good manifold design. Through CFD optimization, we were able to design a wastegate port with equalized flow between the turbine runners and the wastegate ports minimizing turbulence when the wastegate is closed. Our system also uses a single 45mm wastegate reducing the amount of parts in our kit.

Turbochargers:

The Kit is offered in a variety of PTE air-cooled and Spool IFX water cooled ceramic ball bearing turbos as follows:

PTE 6466 Gen2 Ball Bearing Air Cooled -900HP - 1 year warranty

PTE 6870 Gen2 Ball Bearing Air Cooled -1100HP - 1 year warranty

SPOOL IFX-900 Ball Bearing Water Cooled -900HP - Lifetime warranty

SPOOL IFX-1050 Ball Bearing Water Cooled - 1050HP - Lifetime warranty

SPOOL IFX-1200 Ball Bearing Water Cooled - 1200HP - Lifetime warranty

* SPOOL IFX-1400 Ball Bearing Water Cooled - 1400HP - Lifetime warranty available on special request. IFX-1400 utilizes a different riser on the manifold accounting for a bigger wastegate and positioning correction for the bigger frame.
