BMW G8X S58 SINGLE TURBO KIT PTE HP COVER TOP-MOUNT

Designed by Enthusiats for Enthusiasts. We decided to bring a new approach to our usual turbo kits while keeping our word for this one, top-of-the-line components and race-focused performance.

We designed our manifold out of multiple trial and error tests, no matter how much someone tells you you can CFD a manifold design, nothing is going to be able to accurately simulate exhaust pulses and race conditions. The manifold primary runner sizing was determined as 1.25" Nominal Internal Diameter, where it provides good transient response and its volume has capacity to sustain 1400+ WHP applications while keeping EGTs and EMAPs within 7%, each cylinder. Additional to this, we opted for a long runner design, which will create a unique deep exhaust tone.

Unique Clip-In Chargepipe design is meant to be easy to install a provide a secure seal of the chargepipe, paired to the HD Clamps on every joint, you will not be dealing with couplers and hose clamps, which means a tight and secure boost pressure system! (Only added with Turbo Included Kits.

We will powder coat your compressor housing at no additional charge in a wide variety of single coat colors, please send us your choice of color and we will gladly evaluate your request, special and multistep colors will have a charge of $250.

Additionally our manifolds all come Ceramic Coated with Cerakote Titanium, you can custom order your Cerakote color for an additonal $150
