Looking for a Throttle body spacer with the 1/8 npt fittings for my external boost/vacuum gauge sensor for a 102 mm. I got the one from zzperformance but it’s to small. Calling them tomorrow but just wondering if anyone knows of someone else Or where else to “T” into ? Thanks

I have a spacer but it's not thick enough to tap I think. Also you might have clearance issues at the radiator with your air intake tube.

Maybe drill and tap the supercharger snout?

Thanks but not interested in going that route

You could use a nitrous plate and just plug the second fitting

Thanks. This one is way more than I want to spend

This one is way cheaper, might work for you

ur not seeing boost after the TB before the rotors only vacuum, will have to be in manifold after the rotors, unless ur turbo or centri blower

Then where should I “T” into???

What are you trying to accomplish, just measure "boost" pressure? You already have sensors than can provide that info through the ECM, but if you need a mechanical / direct measurement, you'd need to drill into the side of the blower (ie a "runner").

Without drilling or tapping looking to run an aem vacuum/ boost gauge

Just tee off of the fitting that goes the bypass actuator.

Thanks. Is that the small black hose with what looks like a spark plug boot?

 

[Joegngs]

Thanks. Figured it out

Thanks to all, 07gts is right, didn’t get any boost readings on the aem gauge from the sensor on the spacer, I ended up putting the “T” at the boost actuator and all is good. Getting boost readings now and ended up leaving the spacer in as well but plugged the ports.
