I have a FAST 90 on my car and about to install a D1SC setup, and am going to swap out the MAP to the 2-bar sensor. I know the map sensor didn't sit to securly to begin with on the intake, so I used a little bit or rtv and it did fine, but that's NA where it only sees vacuum to ambient at best pressures. Now that I plan to see between 8-10psi of pressure, what is the best way to hold the map sensor in place?

I remember seeing on Hardcore someone had made a bracket to hold it in place, but unfortunately, I didn't save the picture.

Thanks guys.

1/4" NPT fitting like shown. It will screw right in.

^ That's what I did but I actually tapped mine

So then how did you hook up the map sensor to the 1/4 npt? Vacuum hose from the npt to the map sensor using clamps?

I just bent some 1/8th inch SS to hold it down. Took about 5 minutes with a vice.

i used black RTV and a zip tie around it...worked good enough for 6psi with the procharger....

I did the above ,drilled and tapped for bigger fitting. Then ran line to vacuum manifold and ran lines from it to map, fuel pressure ,reg etc. I tried some strapping to hold down map on the back of fast but didn't like that setup much.

Fast is easy to drill and tap.

It's actually so easy to tap, there's no need to tap.

Thanks for the suggestions guys. I'm still up in the air with what I want to do, but I have options.

Ok, so if I thread in a barb to the opening, then run vacuum lines to the map sensor, is it safe to put a t in that line and run a vacuum line to the proflo vavle or is that going to mess with the signal going to the map sensor?

I probably wouldn't do that.

Hmm I wonder if any boost is leaking out back there since I changed my MAP. It feels awfully loose back there when I touch it.
