Has anyone else read this.. it concerns a camaro v6 but could really help us out.

He even has dyno and track data to prove this... cheap hp

WOW pretty interesting. Would be interesting in getting back some expert feedback from this forum. Would just opening up the hood scoops have a similar effect with the current set up or would the placement of those sensors make that big of a difference?

Do a search on HSRK on here. Many threads about it.

...

It's not nearly as much about getting cold air right on the filter as it is about getting the sensor away from the very hot front of the engine. Cold air on the filter is always good, but the data suggests that heat soak originates with the engine and mounting area for the stock sensor.

....

So couldn't we shield the MAF/IAT sensor with an intake insulator to achieve the same effect?

I have been looking into a HSRK for the past week or so. It reasonable that the MAF/IAT heats up, it's located right on top of the coolant hose. I was thinking a cheaper alternative to the HSRK, and less risky given the controversy, would be to wrap the coolant line and possibly the MAF/IAT. It would be easy to tell if this was keeping the plastic from becoming heat soaked, just feel it after letting it idle for a while. I did seem to get the idea from some of those other threads that the HSRK did have a better IAT that could send data to the computer in shorter intervals. That’s just my opinion, I am by far an expert on this but it seems like a relatively straight forward concept. On a related note my last car was a '95 grand prix and after sitting in traffic for a bit the power loss from hot temp readings was incredible, not that it had much power to begin with.

I was thinking a cheaper alternative to the HSRK, and less risky given the controversy, would be to wrap the coolant line and possibly the MAF/IAT.

What controversy? There is no controversy from anyone who knows what they're talking about when it comes to HSRK/IAT relocation kits. The empirical data is out there and the concept is simple and sound.

I don't see how there's any possible way that wrapping components with material that still wouldn't be 100% efficient in keeping the heat away could possibly ever be seen as simpler than installing the ridiculously simple HSRK.

Again, this subject has been covered ad nauseum in other HSRK-related threads...

....

....

Isn't the IAT sensor integrated into the MAF now? I know on older GM W bodies the IAT was a separate sensor located in the intake before the MAF, but I thought they went to an all-in-one type setup. If that is the case we would need to isolate the wires that control the IAT to move it down further on the intake tube.



Some are and some are not.

From left to right on mine I see: Yellow, Pink, Black, Red and Brown / White. Anyone care to wager a guess as to which two are the ones we need to cut and splice?

Seriously, before you do something you'll regret, search on HSRK. There's tons of data on this. If you had searched, you'd know that the HSRK kits use a dual sensor arrangement and don't require any splicing or cutting of wires.

...

No worries, I'm not worked up about it. Based on your wiring post I was just trying to stop you from causing more work than needed. But try this...

Move your mouse to the upper right part of site, select "Search". Type in H then an S, followed by R and finally K. Then select "Go". Then reap the rewards!

Seriously, good luck finding the info you need. It's a worthwhile mod.

....

Actually there was no "Snarkiness" until this... Calm down there big guy. OP wasn't who I was directing my following posts to, they were to the guy who started talking about cutting IAT sensor wires. Anyway, I've given all the info needed to find the answers so I'm out. Back to V8 land for me...

....

Your not making any more HP than what you allready have. Relocating the IAT just removes it away from the heat source, keeping it from being heat soaked. Giving it a more accurate reading of the ambiant air temp, then being affected by the radiator or engine bay heat. When the area that the IAT is mounted in becomes heatsoaked it takes that reading and the ECM pulls timing. At a certain point it used to be around 80-90 degrees the ECM will cut timing anyway on stock programming when ambiant air gets to that point.

According to GM Parts direct the V6 and V8 have different MAF's maybe because of the size and the MAF and IAT is built in. Taking a gander at it they look to have the same wireing. Some of thoes HSRK have a break out harness so that you can remotely hook up a IAT w/o splicing like the old days.

Thanks for the reply, and good information. Unfortunately, my time at this forum is done. Which sucks since I would have liked to continue the conversation.

Not sure what all went on here before I read this thread, but on the topic of HSRK, I agree Swat444. It's incredibly easy to do and inexpensive. It'a also reversible in less than 5 minutes if you change your mind.
