Borg Warner EFR 8374 Turbocharger
$2,642.21
BorgWarner EFR (Engineered For Racing) Series turbos are purpose built units for the performance market & meet the needs of the next generation turbo consumer. Revolutionary from the ground up, each incorporates a long list of features never before seen in a single package. All old technology has been thrown away completely & the result is a whole new breed of turbo, packed full of cutting edge advancements. Great emphases has been put towards a more compact design, making each EFR the ideal choice for applications with limited space available. Outstanding ease of installation & budget friendly (thanks to their 'total package' platform) every EFR eliminates the need to purchase/fabricate/install a separate blow of valve & related flanges/tubing due to their already integrated BOV. The internally wastegated units present another large advantage in savings & install simplicity by eliminating the need for an external wastegate(s), related fab work & otherwise cumbersome materials.
"The Borg Warner EFR 8374 is the 6th size (#6 of 7) turbocharger in the very efficient high performance EFR series. This is one of the most interesting turbos in the line-up with a compressor wheel size similar to the GT3582R, but on steroids with a 62.6mm inducer, 83mm OD exducer. Produces 79 lb/min of max flow that is normally unheard of for a wheel it's size. Supports 750 HP & is truly an outstanding turbo for rapid spool, big HP & high pressure ratios of 45+ psi. The 8374 is the perfect EFR for road race, time attack, street & drag racing when unsurpassed response & yield are required.
