MWR Velocity Stacks for Suzuki GSX-R1000 (2017+)
MWR relentlessly redesigned the velocity stacks for the 2017+ GSXR1000, that they are now the new standard in Yoshimura's Racing Team bikes for both Tony Elias & Josh Herrin. Rather than Yoshimura's own, "Works Stacks:, set includes lower stacks / upper stacks & bolts. The first tests have already been done by WSBK & BSB teams showing that the MWR stacks deliver the same power as the official YEC stacks just much less cost!
Direct from Wilco, the founder of MWR, and the genius behind these championship-winning intake designs;
"We designed and made multiple versions of stacks for the new Suzuki GSX-R1000 and sent them both to the most successful Suzuki Race Team in the world to test them. They already use the MWR "WSBK" filters so the entry was easy. To make all things about the tests clear I’ve added two dyno graphs of both tests.
Both tests were completed by Yoshimura USA
Test # 1
As you look at the dyno graph you see both MWR perform well but not enough to beat the Yoshimura Works stacks. The best MWR stacks increased the power with 3HP compared to the OEM stacks but were 2 HP down (on top) compared to the Yoshimura Works stacks.
So we went back to the drawing table and designed a completely different set. Sent them over to Yoshimura USA again for testing; and received great results.
Test #2
Red line = Yoshimura Works Stacks
Blue line = MWR stacks.
Over the complete range, the MWR stacks are slightly better than the Yoshimura Works stacks and around 12,000 RPM significant difference in power & torque.
This test made the Yoshimura Racing Team decide to use the MWR stacks in both bikes of Tony Elias & Josh Herrin.
