New 5th/6th/8th gen performance header now in production in USA
A pre-production prototype header assembly with specifications nearly identical to the Two Brothers Racing [TBR] 5th gen VFR 800 header is now being constructed in southern California.
This is a new thread duplicating a post on the VFRD '5th & 6th VFR 800 Header build' thread. The objective of this new thread is to give the project described below an opportunity to stand on its own four cylinders. There is a metric ton of valuable data and opinion on the old thread, so if you're
Jozef - our favorite dyno technician in the world and head of tuning at Attack Performance - has provided the maps he built on the dyno for:
5 gen VFR800 tuned with Power Commander 3
6 gen VFR800 tuned with Power Commander 5
8 gen VFR800 tuned with Power Commander 5
These maps will work well on any 5th, 6th, or 8th gen VFR800 with the new performance headers, a good quality hi-flow air filter [We prefer the K&N HA-8098 filter] and a good quality slipon muffler.
