you still are running a IAC don.. looks like thats what the black sensor is on the bottom cloth in the middle? Im suprised...
I have it mounted on the throttle body, but it's not being used. The IAC feature is turned off in the EMS software.
I'm o-ringing some sealing surfaces, adding some additional fasteners to get ready for higher boost numbers (over 30 psi), changing materials of the fuel rails from anodized aluminum and plastic to stainless, fabbing an air bleed valve for the internal fuel rail, and whatever else that comes to mind.
You know me better than that. I wouldn't leave you hanging with one little picture. Custom 100mm throttle body. Configured to be GM friendly.
Last defense poppet valve I developed this poppet valve to guard against intake manifold backfires. It's common to see alcohol and/or nitrous cars turn their intakes to shrapnel. This device has saved me countless times throughout the years. The design is pretty unique. Not the easiest way to make a poppet, but this design keeps the package short.
The cover layed over the valve and bolted through the plenum and into a support plate inside the plenum.
A sandwiching support plate on the outside of the plenum to make for a better seal between the plenum and the runner entrance plates. I use a Motoseal sealer on the mating surface of the runner entrance plate to the plenum.
A closer view of the runner entrance support plate. The notches in the support plate are to clear the electronic injector bosses.
