GrimmSpeed is on your side with our new 160 Degree Thermostat. Our thermostat will make an immediate and direct impact on your engine running temps. The 160 Degree T-Stat will bring your engine coolant temps down 20-30 Degrees. Many OEM style T-Stats can have a very negative effect on your vehicle, if they fail, they fail closed and your car will overheat. But not ours! If there is a failure with our T-Stat, it will fail in the OPEN position allowing coolant to flow and keep your engine temps under control. Given the fact most Subarus are turbo'd, this gives you even more of a reason to want to keep those coolant temps down. In turbo'd applications, the engine coolant must also cool the turbo and the engine oil. This places a greater strain on your oem thermostat...all the more reason to install the GrimmSpeed 160 Degree Thermostat! During testing, we have also found that our 160 Degree Thermostat keeps the engine coolant at a more stable temperature. Quick Facts: 20-30 Degree cooler engine coolant temps Horsepower gains due to the ability to tune more agressively Less chance of the engine killing detonation Fails in an OPEN position compared to competitors products
You may set a check engine light for "coolant temp below threshold" Like my car did when I put in a napa 160 degree stat, it also got horse**** gas mileage. Maybe different on newer cars....
but the GS one fails..... Open. I think that is kinda cool. $53.00..... That ain't too bad, I'd hit that. ( I can haz a good guy discount please?)
This all locks the same http://www.importimageracing.com/mm...MSthermostatsMASTER&Category_Code=wrx-cooling And again i say... When has a Subaru thermostat ever failed?
I had one fail closed on my RS 2 years after i got it. My car overheated and i had to replace the unit.
But the thing is - the cooling fans will still turn on at the factory temperatures, so this is really a moot point.
As dumb as this sounds, you *may* need to get your car re-tuned if you install one of these. There is a correction table that applies a % to your ignition timing based on coolant temp. I do not recall off of the top of my head how much of a correction is applied and to what range.
This is on the 06. I'm not sure if Base Timing Alternate comes into play? If not, then there shouldn't be a change in timing between 140F and 194F.
Ok, thats enough guys. If you have constructive thoughts regarding this product, feel free to post them. Anyone else trolling or flaming will get points.
You may not like the bad mouthing but the problem is this is a joke. And I am sorry if I don't want to see people suckered in because they don't know any better.
so after reading the constructive posts, how do you justify your product being a logical upgrade? seriously, tell all the potential customers why they need your product.
did you not read the rest? please help us with the following topics in the products function ability. if you want to expand on the pricing feel free. - POOR GAS MILEAGE - CHECK ENGINE LIGHT - MAY (PROBABLY SHOULD) GET A TUNE thanks.
Ok, that's a little better. I'm not taking sides, but would appreciate a little more professionalism and grownup behavior around here.
If you can do it without bad-mouthing or being cocky, then fine. Constructive criticism is what we're asking for here. And to be completely honest, your post had nothing to do with "helping out a user" or not "wanting to see people suckered in" It was banter, plain and simple. And another thing, us mods tell you guys this EVERY TIME Grimmspeed makes another product announcement. Just leave it be ffs.
So the one sold by import image is about $8 cheaper than yours. what about the Grimmspeed unit justifies the price difference? and don't say shipping. your local, we have to pay tax.
I can, however, speak to this one. As per the compensation tables posted above, unless you're lowering the coolant temps below ~140 degrees (and on most other Subaru's, the compensations zero lower, at between 80 and 120), there is no need for a tune. The alternate compensation table is not relevant here as it represents the minimum timing that would be used as base ignition timing, if it exceeded the base timing plus all other compensations.
I wont post our Price. Ours doesnt have a fail safe mode... But when you have a failed thermostat thats wide open. Hows that any better for driving?
thanks for the information, i stand partially corrected. i'l sit back and wait for the rest. keep it to PMs?
Just because you make an engine run cold does not make it better or create more power. Having to cold of stat can also cause overheating problems.
I have run a 160* t-stat for over 4 years now without any CELs or other issues. It is likely the same unit that is being sold here under a different branding. It did not require a retune, and ran just fine. The best feature of this thing is that it fails in the open position, meaning that in the unlikely event it DOES fail, you still get coolant flow.
yea not sure what the big deal is, i ran a similar tstat back in my sr20det (prone to running somewhat hot)
Alternate shouldn't kick in at all. When tuning Fuji's previous setup, he too, had a 160* thermostat, drilled, and nothing fishy ever happened. Car ran normal.
tough crowd! best of luck justin, from previous sales im sure they will sell like crazy. maybe not as much as your magical ebc's have but they will sell. usually the northern guys like a little bit hotter thermostat, any plans on making any 170's?
No need for a tune. If I'm not mistaken this one should be the SAME as the Crucial Racing one. I didn't much like the fail safe thiny. Anytime it DOES overheat if you forgotten to plug in your fans, it'll lock the stat OPEN. Even when it cools down, it'll be LOCKED OPEN. When the stat is HOT, it is not likely it'll shut, it'll stay OPEN. SO when you have overheated your car, you need to drain your coolant or water with Water Wetter and UNLOCK the thermostat so it can close. If not you are likely to run COLD on cool nights because the stat is WIDE OPEN. I had no issues running this in the cooler months. I bent the locks apart to keep the stat from LOCKING OPEN. I didn't like that feature. If it overheats, you'll see the temps on your temp gauge. You're NOT gonna let the car run, are you??? lolz
When my water pump sprang a leak on the 2.5RS, I had it replaced at Bloomington Subaru Acura (not my 1st choice, but it was convenient as I drove past it on my way to and from work). The t-stat on the new pump assembly was faulty, and the car started to overheat about half way to Eden Prairie. To their credit, they replaced it with a fresh one the following day, but I wasn't real happy about having to run it at 236F along 494 (I had the laptop plugged in, so I knew exactly how hot it was getting). So, yes, OEM t-stats fail (even brand new ones), and when they fail closed, the car overheats. I'm not entirely sure of the benefit of running a t-stat that opens at a lower temp, but having been on the wrong end of a failed t-stat, failing open seems like a bloody good idea to me. Stuart.
I run a cooler tstat and I have no complaints. No CEL's, no problems. Let the man sell his product. If you don't want it, it's simple.. Don't buy it. There are wayyy more products out there that serve less of a product than this. Go bitch about the turbo whistler or the interfooler if you want to bitch about something that's useless.
if you've ever run a 160 up there in MN in the winter with an upgraded radiator. then you would know it takes a bit longer for the car to warm up. I've been selling thermostats for a long time. the northern folks like the 170's better sure it may only be a few degrees, but with the added failsafe especially when changing radiator/hoses it's the extra piece of mind customers may want. It may not be for you, but i assure you 160 and 170 degree thermostats do not sit on my shelves or collect dust
