BD Turboguard

Blow-off signal is received from the APPS, or a micro switch on the go pedal, depending on application. The BOV is mounted as close to the intake manifold as possible. Boost pressure pushes against both the top and bottom of BOV during cruising/acceleration keeping it seated(along with slight spring pressure). When the pedal is lifted, signal is sent to a spool valve cutting off the pressure to the top of the BOV. The pressure inside the intake is then able to open the BOV, preventing the charge air from rushing back to the turbo and causing a "bark." Yes, it does work well. I don’t think that it is manditory on a diesel, but when someone pulls out in front of you when your making 65psi, you'll probably be glad you have it.

HID--

In your application, I'd think a 16 housing would be perfect. 18 would be a little large.

There was a dyno test series in the TDR mag which showed max HP with the 16 housing on the 35. Larger than that, you need a full 4" because the housing is no longer the main flow restriction.

Spoolup with the 16 would still be reasonable enough, especially with the manny tranny.

The only prob with mounting the 16 housing is that it MAY require a new downpipe. The 16 housings I've seen pics of don't use the cast elbow like our 12wg and 14wg housings do.

From a stock 12 housing, you should lose at least 150° on the top end and maybe pick up a little HP.

Hohn thanks for the info. I am told that that is the next step for the pulling I do.
