I had some open spindle time to I developed a new version of the venerable bathtub intake repop.

This new version uses the same bathtub base and adds a billet lid converting the entire setup to full sequential EFI, with a front style throttle body.

Not sure if anybody is interested in this, but it turned out pretty good so I'll go ahead and post it up. If there is an interest in this EFI Bathtub, let me know I will create the casting patterns to lower costs. Currently it is available only as a billet, which is expensive. As a casting, it will be comparable in price to the original.

If you already have a Bathtub v1.0 (carbureted) you can convert to EFI by sending the base back and I can rework it for the injector bosses (NO welding) and then buy a new lid.

Before we get into the pictures, some highlights:

- The injector rails are hidden underneath in the valley, which conceals the fuel rails, injectors, and injector harnesses making for a clean installation.

- The overall height is very low profile, quite a bit lower than a factory carb/air cleanser setup, and should fit under the hood with ease.

- Vacuum provisions are provided in a "panel" at the rear of the manifold, above the distributor, provisions are for power brakes, auto trans, MAP, and manifold referenced vacuum for the fuel regulator. If not needed these can be plugged. Provision is also provided for a MAT sensor by the front throttle blade.

- This can be used N/A, or also in turbo, Procharger, or Torque Storm force induction.

- Clears stock and aftermarket valley pans w/front PVC.

- Throttle body sizes from 90 mm to 102 mm are supported. Shown is a 92 mm.

It started with a 100 lb block of aluminum and ended up weighing 7 lbs. when completed.



After about 40 hrs. of spindle time, it's starting to look like an intake:
