what up guys.....i was looking at the hsrk, i want to buy it....but i was also looking at buying a granatelli mass air flow sensor....estimating 8-22rwhp that sounds nice....my question is if i buy that sensor will it also become heat soak and will i need the hsrk ??? im buying the new maf but will i also need the hsrk ?

i agree JUNK!!! a few have had it and changed back to the stock maf. adm and lpe are the only mafs i would do they are the same. you will need a tune to run the and have to have it calibrated to work

Not worth the money on any car! There was a guy on LS1tech that put one on his LT1 and lost 6rwhp on the dyno! So I would say spend your money on better mods!

ok guys........not getting that mod !
Why, what changed your mind? J/K.... If your looking at buying a MAF for some type of gain, look at the LPE version(same as adm's). Its a black powder coated aluminum 4" unit w/o a screen. Seems to be working fine for me and a few others out there....:2cents:

Following the "No Vender - No BS" Rule it is hard to defend GMS MAFs when I am Granatelli from GMS (Granatelli Motor Sports). However the LFP or ADM as you guys put it, is no more then a tube with FORD MAF Electronics in it. You are taking your system from a Frequency based sophisticated and thorough system and going to a very simple analog based system. It is a step back to say the least. LPE does not even use it on their own turbo cars. This is the reason it requires custom tuning. If you are all willing to go the route of custom tuning then why not run the proper frequency meter and tune from there. As for loosing power with our meters....not likely...we have a 1 year no questions asked warranty and our tech staff can help ALWAYS.

We have the exclusive aftermarket contract with Hitachi on Ford Meters and Delphi on GM Meters. To say our parts don't work is like saying the factory meter does not work. :dunno: think about it

Its not really a No Vendor site, its just a no vendor BS site.

Meaning Norcal is not going to defend vendors that line his pocket like the other sites.

I thought the ADM MAF was a GM piece?

SSLS2, I would not waste your money on a HSRK. I have done serious testing with it and although I was once for it, I have found its not worth doing. I did this by recording the HSRK sensor and the stock IAT at the same time with my HPT analog to digital inputs and logging to a computer. There is no benefit to running one or at least the Vector unit I tested. The theory sounds great, but doesnt pan out.

No comments on Granatelli as I have no clue. Sounds like a little work would be involved with your MAF tables to get one dialed in to whatever intake you are runnning?

Welcome Granatelli !

I'm gonna have to disagree with you on the HSRK sensor (at least the one from IEATSRT8).... I've done some testing, and some data logging with a Dashhawk... and while not as sophisticated as an HPT, the HSRK into the Airbox along with the CAI & Seal from IEATSRT8 read consistantly lower air intake temps (with 50% of the heatsoak) as compared to the factory mounted IAT on the MAF.....

Yea I thought so too. Originally....

There is no way to test to results of a HSRK kit unless you can log IATs at the same time (stock vs relocate). You cant do that with a DashHawk. IATs are extremely confusing if you are trying to test from day to day or If you pop the hood to swap sensors you lose that blanket of heat and things change.

So anything but simultaneous logging is just seat of the pants.

Believe me, I was a huge proponent of the HSRK. Just didn't pan out.

One of vectors claims to fame is the new style sensor reacts faster. Well the stock one reacts fast enough and during testing seemed faster than the Vector.

I have not tested the IEASRT8 but in talking to him he did not want to make any claims to being faster or less prone it heat soak. It is a better fabricated part than Vectors when it comes to mount and the nice connector he uses.

So in my book the HSRK is the #2 waste of money mod right behind the LS7 TB.

I just cant find my self recommending someone blowing $100 on something like this.

IEATSRT8 HSRK (IAT Relocation)

There is no way to test to results of a HSRK kit unless you can log IATs at the same time (stock vs relocate).
Actually my test was on a roundtrip 20 miles each way, and it was in the middle of the day.... Sept 9th about 50 minutes total 2:00pm - 2:50pm:

I tested on the highway for 20 miles (each way) in 90 degree heat - 70 MPH, and I can say that the IEATSRT8 HSRK does work...(when moved into the airbox as compared to the Stock mount IAT)

The IEATSRT8 IAT read consistantly between 100-102 IAT on the dashhawk, with ECT 198 and Transtemp 206...
on the way home with the stock IAT (in the MAF) plugged in the IAT read consistantly between 109 and 111 on the dashhawk with ECT 198 and Transtemp 206...(sounds pretty 'consistant' to me)
I don't think the sensor is lying, I just think that relocating it to the airbox, has alot to do with the cooler temps...

When I turn on the car in the morning with either MAF sensor plugged in (Stock or IEATSRT8) the temperature is about 1-2 degrees above ambient for both / either....

Please stop bad mouthing all HSRK's until you test them all....

I know you always "qualify" your statement to vector's HSRK, but let's just face it you probably got a bad sensor, ask for a refund, or an exchange.... :biggrin2:

By the way I love SS-Shootout.com ( alot of good info )

You are right, I always qualify that and say I have not tested the IEATSRT8.

But I have done hours and hours of testing with IAT's in general and I don't care whos they are, I learned you cant test them the way you did. A slight pause in your trip will elevate IATs that you can't recover, change in head wind, etc. Engine coolant temperature is a small factor with IATs'.

Besides I (note I said I) really dont care how the IAT reacts after 20 miles of driving. Its much more important how it reacts after you sit stopped for 5 minutes and then the next 1000 feet after that. The fact you have drive a mile let alone 20 to get data indicates there is a general flow problem with these trucks.

If people would spend as much time and energy into getting a little cold air into the airbox as they do the HSRK they would be 100 times better off.

I will further say that I was using a vector intake at the time which sucks as much under hood air as it does headlight air. So the fact the IEATSRT8 has a superior seal might contribute to the improvement of a relocate.

And how did you prove your HRSK was even reading the corrrect temperature at 70MPH in the 100 -102 range? I found the vector to read cold thus simulating impoved conditions.

Thanks for the compliments on the shootout site. Easy to add data as I am in the online web business. Nothing fancy but it works.

So you are right, at this point I dont know if IEATSRT8 works better or not. I do know, IAT's are finicky.



Thats my :2cents:

Not quite sure what you meant by this, but I was monitoring ambient air temps, and they were consistantly 90 degrees (no fluctuation)... the stock air box sits on the washer fluid tank, so it too "soaks" up heat from the engine compartment, but only 'about' 50% as compared to the stock located IAT (10-12 degrees vs. 19-21 degrees)....

Another observation I didn't go into was the recovery time... now I didn't go as clinical as my other test, but rather will give my 'seat of the pants' recovery time of IAT temps from a stand still..... (stopped at a light) the recovery times are probably three times as quick (from about 10 seconds for the IEATSRT8 to about 30 seconds for the stock IAT)... recovery defined as getting back to the normal reading or the average range for each sensor....

again just my :2cents:

Once again, just comparing it to the Vector. It was a linearity thing above AAT. The higher the temp, the more the error.

I suspect the seal on the airbox plays some part in the results of a HSRK. If the IEATSRT8 is pulling cooler air across the HSRK/IAT then its going to work better.

If the Vector had the same exact sensor but it was pulling heat soaked air from under the hood back into the box and past the HSRK/IAT its still reading heat soaked error (no change).

Most people are looking for the HSRK to improve the performance away from the stop light/tree. If you sit in the staging lane or traffic for a couple minutes IATs climb regardless. Shut the truck off and it will burb hot air all the way to the filter.

You want to see IATs drop fast, do something like Skiba or Balistikss has done.

Until we can get to that point, there is no winning. Just look at the IAT tables in your tune. Doesnt take much temp elevation and your timing is in the gutter.

I have access to a IEATSRT8 HSRK but really dont want to put my Vector intake back on to test it. In the middle of tuning for my ADM intake.

Feel lucky your HSRK has a real plug on it and not the micky mouse one Vector ships !

I will agree that the IEATSRT8 CAI + IAT + Seal probably works better than your (probably defective) vector setup did (that you tested)....

I definately see an improvement (imagined or not), and do not see any draw backs other than compared to a "theortically" perfect intake set-up (that keeps the stock airbox on top of the heat soaked washer fluid).....

Asking a question like: can you get a better set-up???
Is like asking the question: can our engines make more horsepower???

Answer: How much money and effort are you willing to spend? :cheers1:
