just want to make sure I am doing it the rite way in round two and figured I would make and post this to double check whilst I wait for my piping and ic to come in. The only thing I am not sure about is should the iat sensor be on the intercooler or the piping after the intercooler and before the diverter?

Switch the boost gauge and the MS feed. Getting your MAP sensor signal from right after the throttle body tends to be problematic because the air is very turbulent there and will cause your tune to be screwy. Actually most people tend to tee off of the FPR for the MS. Looks good otherwise.

Sweet, thanks for the advice!

I forgot to put the line for the diverter...that comes off the same pipe as the mbcv/diverter.

The diverter needs to be run after the throttle body, not before. Also IAT sensor needs to be after the intercooler.

Yeah, what I said doesn't actually make sense...and the iat I was planning on putting into the end tank on the cold side of the ic, but I could put it in the piping also. Really want to make sure it will be cooled by the air to avoid heat soak.

I would move the mbcv line to near the compressor outlet.

dustinb

Heatsoak really shouldn't be an issue on the charge pipe side. I think you definitely want it to be an accurate representation of the air going into the throttle body, so I was put it about half way or closer up the cold side charge pipe.

T the MS line in with the FRP line, you'll have much less noise there. And then T the boost gauge line off of that one inside the cabin, makes for easier and less hose routing.

Sweetness, I am sooooo glad I made this thread. Thanks alot for the recommendations!

x2 thats exactly what I did

Would it matter which port I take the signal for the diverter off of? I think no but I am not positive.

not really no.

just tee the MS to the FPR, then tee the boost gauge off that inside the cabin.

Just for reference, this is how mine is laid out (Not a current pic, but the important bits haven't changed)

Looks great, I will probably run the line from the tee into the car and under the dash I will tee once again for the boost meter and megasquirt. Is there any benefit to having a filter on each line or could you just have 1 filter after the tee off of the fpr? I feel the latter is the better but would like someone elses input.

I wouldn't.

If you do this, then boost will decrease as RPM increases. The reason is that pressure drop across the IC is a function of the mass flow per unit time through it. The more air you pass through the IC, the more pressure you lose across it.

If your MBC is referenced to pressure before the IC, then pressure after it will decrease correspondingly. By placing the MBC takeoff after the intercooler (but before the throttle) then the system will maintain a constant pressure after the IC by gradually raising pressure before it to compensate for this drop.

^agree

Oh, I thought having it close was better for keeping the pressure steady. I guess I'll move mine.

So this is what I am going with, there will be one filter on the red line coming off of the fpr. Thanks again to everybody who helped aim me in the rite direction!
