Harman Motive : GT-R Upgrade Results

Dyno Graph: Stock R35 vs. Final Stage 2(+50whp and +55tq)
Harman Motive Blog

Harman has done a few upgrades to their GT-R. All dyno runs were on a Mustang dyno, on 91 octane fuel.

With the midpipe installed and still running the same Cobb Stage 1 map we saw a gain of 16whp and 13tq. Beyond that huge gains in response and spool can be seen along with a slight increase in boost. The stock midpipe is definitely a major point of restriction on the R35.

Results of Testing

Stock 401 393 11.8 psi
Cobb Stage 1 426 414 14.0 psi
Cobb Stage 1 w/ Harman Motive Midpipe 442 427 14.3 psi
Cobb Stage 2 w/ Harman Motive Midpipe 450 448 14.9 psi
