What can i tee on the IM?

[lars y]

I have four nipples on the intake manifold, and i have five things that need to be connected to it.
Its a BOV, MAP-Sensor, catch can, power brakes and the fuel pressure regulator.

Wich two can i tee together to the same nipple without making trouble?

Thanks

MAP sensor can be t'd into the FPR line or the emissions 'P' port. Everything else should have it's own designated ports

 

[Clutch450]

You can "T" into the MAP or FPR line
Do not "T" into the BOV or Catch can

 

[lars y]

Oh, ive heard i shouldnt "T" into the MAP line, since it needs to know exactly what the pressure in the IM is.

Im not running with the emissions system or the stock IM.

I was going to "T" the BOV and the AFPR together, as the AFPR is just a membrane so it shouldnt be messing too much for the BOV?

 

[NHerron]

It will make a difference, don't do it. Keep the BOV on it's own designated signal.

Thanks for the clarification on what you want to do.

I'd say your best bet is to tie the FPR & MAP together. The brake booster line would be kinda tough to T into, since you would need a specific adapter/reducer and the catch can ...well it's dirty.

FYI The most common place to add a MAP sensor for a boost gauge has been the FPR line for a while now. Make sure to boost leak test the system afterwards

Best bet would be the map and the fpr eve4ry thing else should have its own source

+1 on FPR and MAP

I have my FPR and BOV line into a T because I only have 3 ports on my intake manifold, and I'm using the other two for brake booster and PCV. I had it separate before and now together, it makes absolutely no difference. BOV goes off exactly as it did before under the same pressure.

 

[NHerron]

Maybe for you. But more often than not people have had response times change when t'ing into the BOV signal.

If you want to free up a extra port and don't car about emissions, put your boost gauge on the p port on the throttle body and there you go. I plan on t the map and fpr.

I used my MAP sensor T on the Booster line with out a problem, It is not hard to do it, Just use a 1/8 T adapter and add some Thread locker and that's it,

 

[lars y]

Alright, thanks guys!
I will tee the FPR and MAP together, it seems most people recommend that.
I`m making everything from scratch here so its no more work for me to do that.

By the way, i was told i really shouldn`t tee anything into the break booster as it will 'chug' in a lot of air when i hit the break pedal.

Why not use a vacuum distribution block?

 

[lars y]

Hmm, yea i haven`t seen one of those before, ill look into it, thanks
