IAT Temps for PD Blowers

[Brian Z.]

Curious as to what everyone sees with PD blowers in this hot ass summer as your:
1. driving in the city
2. driving on the highway
3. sitting in traffic

Also, is the IAT temp reading on my ngauge accurate?

I have a KB blower and typically see when temps are above 90 degrees and humid:
1. 118-122
2. 117-121
3. 128-130
Obviously it's much lower when the temps are lower outside like early in the morning or late at night, but we've had a really hot summer here in Indianapolis.

Mine got to 133 yesterday in stop and go traffic, thats the highest ive seen it.

I've seen up to 150 in stop and go. Deep South Texas. Over 100 every day all summer. When cruising, it's obviously much lower. Around 110-115.

Your Ngauge is reading the IAT2 though, correct?

Not certain which one it's reading with the KB. Which blower are you running?

NGauge will not read the correct IAT2 (post compressor) reading becuase the PID is not calibrated properly for that sensor. I have the Ngauge reading the PCM's IAT2 and another separate standalone IAT sensor read through a Zietronix ZT-2 and the reading are not the same after 100 degrees. I can see both IAT 2 reading displays, and the Ngauge IAT2 is very close to the zietronix until 100 F then it starts to split and the Ngauge reading starts to loose it's accuracy and reports lower reading. The Ngauge at full temp is off and lower in temp then the Zietronix standalone by 15-20 degrees.

The most accurate reading for IAT2 will be from a standalone system like I have until someone is able to alter the PID transfer function for that sensor and make it accurate.

With my standalone IAT2 zietronix sensor with 80 ambient temps I see.

1. 125-130
2. 120-125
3. 130-145

Whipple Flight control monitors CHT to pull power. Should it also be able to monitor IAT2? What numbers on the Zeitronix would cause concern ?

CHT Limiting. The CHT limit is based on the cylinder head temp. After extensive testing using the advanced 3D based calibration, a peak power calibration was made for all different types of scenarios. The S550 uses CHT to modify the power output as temp increases, power levels decrease.

CHT and iat2 can not be compared, but yes WHIPPLE flight controls pulls power if ECT IAT2 or CHT get to high. The only problem is the IAT2 Whipple sees is not available for display through Ngauge or other monitors. Whipple has said they will eventually have a data logging system that will be able to see real time all these parameters accurately.

The 145 f iat2 I referenced is when driving stop and go slow speeds hot day and according to Whipple will come down significantly when the bypass closes under load and air really starts moving.

Roh we spoke a while ago on IAT. I'm glad you posted these. Bravo for moving this thing forward. I believe the centri guys have been able to check temp after heat exchanger and as entering intake. Does a direct PD vs centri comparo exist yet?

Sure there are some with PD setups who have a standalone system like thermo coupler sensors. But for a true IAT head to head between a PD and centi you would have to have these side by side for same conditions data logged right.

I had a stand alone IAT gauge installed in my Lund tuned DOB kit. It read a few degrees warmer than the IAT2 reading on the nGauge. My car runs 10 degrees over ambient on the nGauge at all times. You see a rise when the car is shut down and parked but that soon drops to 10 over and a momentary rise when making a hard pull that too drops quickly.

Can you explain where your getting this IAT data? 10 degrees over ambient is what is read from the IAT1 at the MAF, it's nearly impossible for the air to run through the compressor and not pick heat.

1. What sensor is used
2. where is it connected
3. Where is it displayed

Are any of you guys using this from VMP for your VMP, Whipple, or Kenne Bell setups?? Terry@Beefcake Racing told me to get one ordered...

True but keep in mind that the same heated air is going through a intercooler/heat exchanger before it goes into the cylinders. What Mach just posted is required if you do a Lund tuned Whipple I believe bacause he wants to know the "real" intake air temps. I'm curious what the delta between the MAF IATs and the Real IATs are.

VMP Gen2 TVS - drove it to work the other day in this nice muggy 91+ (car said ambient was 95) degree Florida Heat. Over 40 miles each way to work, mix of traffic and highway. (My drive sucks)

IAT2 (post rotors) monitored on dash, and with the NGauge via VMP Relocation harness

1. driving in the city - 120-124 average
2. driving on the highway - 111 - 115 average
3. sitting in traffic - 125 - 133 average, never seen over 133 sitting in traffic.
