Hi I'm doing a single turbo harness conversion but should I get a fast reacting iat sensor for a 500hp build.
Thanks

 

Yes, the fast reacting IAT is better even in a stock FD, some even relocate it to the post IC charge pipe.

 

Hi what brand iat sensor would you use also what connectors would you remove for the harness mod.
Thanks

 

C. Ludwig on the forum sells these for the FD.

Here is a link to his website: 12mm Intake Air Temperature Sensor (FD RX-7 direct-fit)

 

You can also get them from IRP, Just email them or send Ihor or Rich a PM, they'll get it to you quick.

 

Hi should the iat sensor be before or after the water/meth injection.
Thanks

 

You can use the triumph sensor, Wannaspeed sells them with PnP harness.

There are lots of discussion on where to put the sensor, some put it before the WI nozzle some put it after. I don't really know which one is the best as I didn't hear any ill effect on either configuration, but I'm putting my IAT at the stock location and the WI nozzle in the post IC charge pipe.

 

Can anyone chime in on how reliable/bulletproof the Triumph sensor actually is?

I was about to get one, but the guys over at FDRX7.com told me that they are poor quality, unreliable and will not stand up to the job and to leave the stock one alone.

Anyone been running one for any length of time with/without problem who can prove/disprove this?

 

Strange, I've only heard pretty good things about them but no first hand experience with it, was going to get one though. I know a fast acting IAT sensor is highly recommended especially with AI.

 

FWIW..IIRC from the AI stickys and his other posts, on mildly modded cars...like mine, Coleman recommended that the sensor be before the nozzle so as not to affect maps.
My IAT was relocated some years ago, even before my AI system, with no ill affects.

Hi wouldn't you want to put the iat sensor after water/meth because when it start to inject the temp changes.
Thanks

 

I suppose if you're tuning with it, then yes. But my car isn't high hp, I'm still on stock twins and near-stock boost levels. I added AI/WI just for additional safety, cooling and carbon control.

 

There are two different Triumph sensors. The green one and the black one. Always bet on black...

 

What's the difference?

 

The black one is built more "robust" so durability with elements higher than the green sensor. Both provide the same readout. As long as you don't have puddling and saturate the sensor you'll likely not run into problems with either though.

 

The green sensor was an earlier model and the thermistor was directly expose to the air flow.
The black one is a newer/better design where the sensor is protected by the brass tube.

Go to TRIUMPH 2007 DAYTONA 675 AIR TEMP TEMPERATURE SENSOR 2100807 items in Los Angeles Motorcycle Salvage store on eBay!

the bad version is top right on the page.

 

The element itself is more robust? Still open element?

So looking at that page the black version appears to be a closed element sensor?

 

So basically the good sensor to buy is the one posted at the top on the URL.
Thanks

 

What is the response time with the shrouded Triumph sensor? I can't imagine it's going to be much better than the stock sensor. The point of the open element sensor is quick response after all.

 

That's exactly what I was getting at.

 

This is a coolant temp sensor. Fully shrouded. Guy doesn't know what he has.

This is the "old" Triumph air temp sensor. No shroud. But, ooops, it's black.

This is the "new" Triumph sensor. 12mm Intake Air Temperature Sensor (FD RX-7 direct-fit)

 

I get it now. The one people want (the good, revised version) is sold by C Ludwig/LMS EFI.com.

 

Alright, thread revival time I suppose. I'm not looking to pay $90 for one of these from wannaspeed, but am unsure which version everyone likes these days. As far as I can tell:

Original green sensor, exposed thermistor: T1290510

Alternate black replacement, exposed thermistor: T1290627

Alternate black replacement, 'shrouded' thermistor: 70416A
^(this appears to be what wannaspeed sells)


Which is going to work best for me with a heavily modified car and PFC?

 

Bump, wondering which sensor is best to buy.

 

It's up to you to decide after reading above. The open element version is going to be the fastest but probably not as long lasting. Haven't been to the wannaspeed site for a long time but IIRC he did some testing against the OEM sensor with faster response. Seems like $90 shouldn't be all that big of a deal for someone with a "highly modified car".
