Pretty quick in full street trim. Proper VBOX test and best guess using backwards lights at drug track lol
Many many twins set ups here > http://www.riceracing.com.au/vbox-iii-testing-tuning.htm
(click on any of the FD3S car) with VBOX link to see boost pressure, AFR, accelearrtion settings and most importantly real HP at the wheels! that equals reality when you apply physics to estimate bhp from the engine and the weight of the car!
Alll kinds of twins and motors tested (stock, T28 internals, RF420\'s, sequenatial, no seq, front mount IC, stock mounts, even stock std Spirit R Type A!!!) ported motors to std 13B-REW\'s up to 20psi boost pressure, allkinds of dynos and most importantly real world back to back tests over set speed acceleration increment tests.
