Yesterday dyno session with friends Rallycross car...
So, we have little problem. Friend rebuilded 13B PP engine. Rotors are Renny rotors now...
It had really long intake with 62 throttlebody. Now it has 50.(unfortunately I dont have picture now)
Header is abit different too... (shown at that pic)
Those are 3 changes made to this thing. So, problem is that it not making enough power. Power and torque curves are identical with previous setup, but just much lower!
Could this header collector be a problem? Well, I know it is but
Also, what best lengt for intake? And how we can calculate optimal for our setup?
