you guys with built up motors....... Its a small mod but i havent done it yet.......HPP3 and 160* stat. If i get it now can i keep it as long as i have the car no matter what i do to it (i.e. 10 years, an ARE). And something i always thought about was whether these 2 mods made you motor work harder and put stress on it by haveing it always run fluids and the fans. Do they?
Re: you guys with built up motors....... The 160 t-stat you'll most likely keep in the car as long as you have it. As for the HPP3, it will all depend on whether or not your custom tuning will be compatible with it. The only custom tuner out there that still allows you to use the HPP3 is MTI. Any other of the tuners won't let you use it, so you'd have to sell it or put it on your mantel. <img src="gr_stretch.gif" border="0">
It doesn't put more stress on your engine by having it "run more fluid", etc. The water pump is always turning; it's driven by your belt. The t-stat just controls when the coolant is allowed to circulate throughout the engine. With the 160 t-stat, the coolant will begin circulating at a cooler temp.

Re: you guys with built up motors....... Well heres the thing. I would just use it for the fans with the stat. And since i have a Granatelli MAFS i cant use the tuning. The only other thing i would use it for is the rev limiter. Now if custom tuning includes raising the limiter then would i be better off getting the fan switch? I just would think that its more to think about having to switch a fan on and off. I think you guys running 10's and 11's resent fan switches as a starter mod. Or am i wrong. should i just get one?
Re: you guys with built up motors....... The fan switch is a good mod, especially if you dragrace alot. It was nice to have while sitting in the staging lanes on a hot day, really cooled the motor off quickly. My only problem is that I had mine hard-wired without being tied into the ignition off/on relay and I'd forget I had it on sometimes. I was rewarded with a dead battery a few times <img src="gr_sad.gif" border="0">
I've been running the Hypertech fan setting for nearly 3 years with no problems, and I also have the 160F T-stat. Definitely get the T-stat, it keeps the coolant under 185F and therefore helps to reduce knock retard.
Custom tuning is the way to go. Wait until you can get someone to tweak your PCM with LS1-Edit software, you will be happy.

Re: you guys with built up motors....... Is there a big difference between the 160 and the 185...I heard that the 185 really shows no difference...but the 160 does??
Opinions Please.. <img src="gr_stretch.gif" border="0">
I find that when at the track if you let the car cool down to about 160-170 in the staging lanes it will run a lot stronger..

Re: you guys with built up motors....... Trevor...
I just had a PCM tuned by MTI. It should be here any day now. I got an e-mail from Jayson saying that he no longer recommends the use of an HPP3 with his tuning. Here is an excerpt from that mail:

Hope this helps!

Brian, I have a 180 stat, and with the HPP3 180 fan settings I usually stay at 190 to 205 depending on weather and how long I’m sitting idling vs driving. Sometimes it gets down to 185 while driving. I’m not sure what MTI sets the fans to for a 180 stat, so we’ll see with my new PCM if my running temps change any.
My car seems to run faster at about 190 to 200. Below 190 it feels slow, and above 200/205 it feels slow.

Re: you guys with built up motors....... I was told by a couple different mechanics that if you put in a lower thermo, and run cooler, the car will remain in "closed loop" and the computer wont run right if not up to full temperature. Someone want to elaborate on this??

Re: you guys with built up motors....... "I was told by a couple different mechanics that if you put in a lower thermo, and run cooler, the car will remain in "closed loop"
Actually, I think they meant to say it would remain in open loop if it didn't get warm enough. But, even that is not the case. With a 160 thermo it will still easily make it to closed loop operation. 160 degrees is where the thermo starts to open. Actual operating temperature will usually be between 174-182 degrees, depending on conditions.
So, no problem! <img src="gr_stretch.gif" border="0">

Re: you guys with built up motors....... My opionon is that if you are going to do Heads/Cam in the future and plan on getting your PCM reprogrammed stay away from the HyperTech Programmer. Plan everything out at one time where you want stuff set at like fans and rev limiter. That way you will only have around 450-550 in PCM reprogramming instead of 750-850! When LS1 Edit gets here, if it gets here that will be an awesome tool for all of us.... <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

Re: you guys with built up motors....... there is a post above about a guy leaving his switch on and draining his battery. If you dont hard wire it and just plug it in, doesnt it still maintain normal opperation? Its not like if i gorget to turn it on the fans will never start and the engine will overheat it is? And what about that situation with that one guy whose motor overcooled?! <img src="images/icons/rolleyes.gif" border="0">

Re: you guys with built up motors....... Doug thats what i was thinking of. I plan on a cam within a year and heads soon after that. (around when i graduate). So i see no point in the hpp3 for rev limit and more rpms, and for that sake cooling. But, im not going to spend some $400 on tuning for just the rev limiter, and fan settings. I would wait till the cam. So this brings me back to my question. Do a lot of people have a fan switch with the 160*? and should i get one?

Re: you guys with built up motors....... Alot of people have the 160 T-stat and manual fan switch. From what I've seen and read the LS1 makes peak power at around the 178* mark. So the 160 thermo would put you right in this range and the 180 a little above. The fan switch will allow you to turn on your fans manually otherwise prepragrammed through your computer I think at 215 or something like that. In my view it's a good mod because it's something that should never need replaced by the lastest and greatest update!
