Enjuku's  700 rwhp rb25.. testing and adjusting NOS engagement.. throttle response and tip in. All the power in the world is worthless without good transient response on a drift car. Just listen to that on off transition... all on a R.S. Enthalpy rom tune.Solid E85 setup with a Holley  programable  NOS controller, super responsive GTX 3582 at 25 psi.#rsenthalpy #enjukuracing #s13 #240sx #rb25 #rb26 #s13 #holleyperformance #turbobygarrett #tune #formulad
