STEP1 Inhalation exchange (genuine exchange filter) + exhaust type 　　- 293/7000 (10PS UP) 42.8/4400 (2.8kgm UP)

STEP2 Inhalation exchange (racing suction) + racing plug 　　- 305/6800 (22PS UP) 45.1/4000 (5.1kgm UP)

STEP3 STEP1+STEP2 + Exhaust type ([metarukiyataraiza] [sentapaipu]) 　　- 313/6800 (30PS UP) 46.4/4400 (6.4kgm UP)

STEP4 STEP3+STEP2+ EVC+ racing plug 145kPa 327/6700 (44PS UP) 46.2/4400 (6.2kgm UP)

STEP5 STEP4 + Control type + revolution revision (EVC) 155kPa 352/6400 (69PS UP) 47.3/4300 (7.3kgm UP)

* expression output torque because of the numerical value which at the chassis dynamo of this inside the company measures this corporation vehicle, differs in the difference and vehicle solid difference of the measurement equipment.

 

すごい、in step 3 that's really metal catalyzer and center pipe. one of these days i'm going to switch from a manual boost controller to the EVC 6
