Whipple 2.9L CHT 225F IAT 160F in traffic

Wouldn't you want to see downstream (iat2) on the dash instead? Good indicator of a pump problem or flow restriction.

Iat1 stays as is which is what the cluster shows. We add iat2 and a harness that connects to the imrc wiring and that reads to the PCM. Unfortunately we don't reflash the cluster so it does not read iat2. Iat2 will never be that hot.

Right, but answering to the question of the lethal AIT harness used with a Whipple cal. The Lethal harness moves the AIT reading from the MAF to the AIT 2 location post compressor correct? This would not work with the Whipple cal becuase it would then eliminate the reading from AIT 1 and the ability for the whipple cal to see and calculate the difference between AIT 1 and AIT 2 correct?

Absolutley, but the whipple cal does not yet have the ability to show this even though it's calculated by the PCM. My understanding is Whipple is working on a full data logging setup with flight controls and I'm sure AIT 2 post compressor will be seen.

If I get the harness, would it work with a whipple tune or does it interfere with anything? I would want it to only be able yo see it in the dash , I dont have the ngauge

No, we supply a pigtail to IMRC connector, which works perfectly.

It would be great but not needed since the PCM does all the thinking for everyone. Since the pump is controlled by the PCM, it can also set a code when not working.

It would not work.

All kits now feature a plastic MAF, plastic air box that is enclosed (better sealing) and plastic air tube. All helps reduce heat.

It really doesn't matter what supercharger you have, you will get hotter inlet temp (pre SC) on a hot day, black pavement, etc.

The intercooler system effectiveness is far greater when ambient temp is higher so you won't see those temps post SC.

Pics on request for anything below:

I have a mid December 2015 Whipple airbox (not sure if they are still evolving). Its a fairly beefy box and partially enclosed.
Some air from behind IC core and from drivers wheel well enters.
The fans in front of the IC throw air centrifugal outward as well as thru the IC core. The airbox pulls from the wash air when stopped in traffic.

I cut some metal to ease airbox lid installation but it can likely be done without. Hard to recall after the 8th beer, and yes, this kit could be installed drunk cause its that thoroughly laid out.

I silicon-ed one gap at the air box metal plate. William sent me a different metal plate that would have fixed issue. He also had me rotate MAF forward from seeing a couple pics I sent him. Not sure if there is a different airbox then what I installed. Ill have to check the airbox porn thread...

As far as IAT1 vs IAT2:
I was talking IAT1. Would love to log/observe both.

We should be able to get IAT1 wayyy cooler than that. I likely botched something in the install. Was I supposed to cut up the stock airbox and inlet to mount to the Whipple airbox?

Dustin,

So if you've changed the MAF and intake casing is the one I am running now sufficient? Also, my nGauge shows IAT2 on it, would that not be accurate? I have it always plugged in and it usually reads about 25 above my IAT1 which I can see on my dash. Also, my intake is pretty dirty, is there any way to swap this out or is it good how it is? I have heard different things before about a clean intake vs a dirty intake so I am curious what you have to say about this.

 

[sigintel]

Can you set nGauge show IAT1 and IAT2?

We don't cut the stock box.

You can cover the box in heat resistant shielding, but when the fans are on, the entire engine and components heat up.

In general, the factory hood does not do very well in removing the heat from the engine in traffic. Does good down the highway, but city streets its not very good.

Not in this application.

There is no difference at highway speeds, during traffic, the plastic components stay cooler than aluminum or steel.

Not sure what IAT2 it's showing but most likely it is not accurate.

As for a dirty intake, not sure if you are referring to air box or filter. Filter should always be clean, but the filter is massive so it takes a lot to cause an issue.

Ok cause the nGauge even says I can monitor ECT's, so I was just curious if all of these features in the nGauge were accurate. I am referring to the filter. How do I go about getting a nice new clean one? I have the open air box not the enclosed.

Just wash your filter. You don't replace these every time they get dirty like a paper one. You can hit just about and auto parts store and but a KnN air filter cleaning kit.

ECT is a valid pid so you can monitor. But there is no sensor so it's a calculated value based off Ford models.
