I'm doing some upgrading of my intake and thought I'd share some pics of the O/H.
you still are running a IAC don.. looks like thats what the black sensor is on the bottom cloth in the middle?
I have it mounted on the throttle body, but it's not being used. The IAC feature is turned off in the EMS software.
thats what I figured
What are you up to now Don? Looks interesting....
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.
Gonna try to add more N20 this year or just more boost?
More fuel, nitrous, boost, suspension and tire.
I look foward to the videos Don.
I'm biting at the bit myself.
PLEASE!!! Show us more.
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.
The throttle body mounted to the upper plenum cover.
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 with the adjuster bolt and the spring plate with springs.
Springs and spring plate set atop the poppet valve.
The cover layed over the valve and bolted through the plenum and into a support plate inside the plenum.
Runner entry plates bolted to the plenum. The runner entrances use an eliptical flare design.
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.
