We put a stock SR into My friend Wardle’s S12 notch and it ran a 13 without any bullshit, just custom exhaust/FMIC by Joe at union. and he ran that 13 on tires that were fucked and quite a few boost leaks.
S12 is the best S chassis. Most solid and most light, also most overlooked.
Are u getting rid of the secondary butterflies completely?
just heard a lot about how it gives more torque and power lower in the rpms when set up properly, but is it really worth the complexity to keep it as intended. though if u get rid of it completely u could probably get better flow in the topend theoretically.
We will be keeping them because there is a very noticeable difference having them hooked up correctly. There is a way to remove the factory vacuum system that makes them work by using a Volvo cruise control vacuum pump and a relay and some creative wiring.
It simplifies the system immensly and actually makes it work a little better.
Removing it will yeild no extra flow unless you were to do extensive work to it and were requiring massive flow rates. It’s plenty good enough for up to 400hp.
So it’s been quite awhile with no updates until today.
The parts I ordered came in today, except for the piston rings which they neglected to tell me that they couldn’t get. Fuck Nissan employees can be really dumb.
