Haluaisinpa tästä nähdä rehellisen penkkivedon back to back. Ekaks mopo säädetään optimiksi vakiolla, ja sitten tarvikkeella. Muu on mutua ja markkinamiesten höpinöitä.
Tuossa ei säädetty laitetta, mutta back-to-back wetoja on ollut paljon. K&N vs OEM suodatin. Testi on vanha, mutta en usko että lopputulokset tuosta nykyään minnekään poikkeavat.
Kuten yleensäkin, K&N tiputtaa tehoja, eikä luultavasti ainakaan paranna suodatustehoa.

We ran the following tests regarding air filters on a stock 929 with OEM exhaust, Hindle bolt on and Hindle full system:
OEM filter 3 runs:
OEM Exhaust best run: 121.5
Hindle bolt on best run: 124.0
Hindle full system best run: 133.5
K&N 929 replacement filter:
OEM Exhaust best run: 119.0
Hindle bolt on best run: 121.0
Hindle full system best run: 129.5
"Whacked" filter (all paper removed, both screens remained)
OEM Exhaust best run: 124.5
Hindle bolt on best run: 127.5
Hindle full system best run: 137.0
These test were run on 108 Octane Sunoco "pump" race gas on a DJ 250 and were made without any third party fuel management system (i.e. PC111 etc.) The test site is 530 ft above sea level and all readings are SAE sea level temp and pressure corrected from "actual" 80 degrees ambient temp and 74% relative humidity.
The same set of tests run on Torco Stealth 14 followed almost identical curves, but yielded an average of 3 additional HP except for the full system with the "modified" OEM filter which produced 144 to 146 HP in 12 consecutive runs.
Pair system was removed (and sealed) while the flapper was IN during all tests.
