Do you guys leave the stock map sensor on the tb and just tap into vaccuum somewhere else?

I think somebody needs to have some flanges made that will bolt up in place of the stock map and give you a nipple so you can hook up the 3 bar

 

The stock map sensor makes for a good plug so i just left it there and just drilled and tapped another barb fitting for the 3 bar map.

 

During my install, I quickly (the key word here being quickly) fabbed a plate that I cut out from some aluminum, drilled some screw holes and mounted it. The oring under the stock MAP sensor seals it. Then I connected the GM MAP to a nipple on my manifold. If I ever get around to it, I thought of connecting a barb to this plate, either JB Weld style or maybe make a new plate with thicker aluminum or steel and thread it on. It probably wouldn't make any difference, vacuum is vacuum, but it would look neat.

 

leave the stock map in there(TB) and then tap your intake manifold for another vac source.

 

Problem is that after a certain PSI won't the stock one be damaged and then no useless if you ever need it again?

 

That's a good question.......does the map sensor just not register the higher psi or does it actually break?

 

I made a block off plate similar to Farnsrocket's. Mine has a nipple connected to it. I used my Missing link as a template.

 

Just make a plate for the hole you created and make sure the 3-bar has its own dedicated source!

 

hey Doodoo, how did you connect the nipple to the plate??

 

Here's how I did it about an hour ago

 

It does the first until it does the second.

I think Speed PHreak has popped a stock MAP in the 8-10psi range. They read boost and all, but it's pretty near the limit of their diaphragm's travel and they don't last as long due to the stress... lasts a fairly long time, but it's not 100% reliable like stock.

 

I ruined a map by purging my nos. I think I over pressurized the manifold.
I would remove the stock map. Then fab your own block off/nipple set up.

 

... great info!!!... i wish i was boosting that hard...

 

Looks good Hatchblack!
