whats the general purpose of an hightemp "(180degree) thermastat?
(even if I did manage 10,000 miles last year.)
do you think there is a noticable increase?
Stock T-stat is 195 and you can get 180 and 160.
I have the 160 but most will tell you not to go lower than 180. I do not have any issues with the 160 but mine is not a daily driver(even if I did manage 10,000 miles last year.)
Higher running temp is supposed to help gas mileage (so the automakers believe), but if it does, it is negligible.
If you put in a lower t-stat you may never get out of the warm-up loop and your mpg gets worse because of that.
.
back in the carb days, a hotter intake plenum helped keep the fuel suspended in the Air Fuel Mixture.. so it really DID help out in the older NON FI cars.
newer fuel injection that is directly squirted into the intake port of the head doesnt NEED a high intake temp to keep the fuel atomized.
For every 10 degree's you drop the intake air charge is worth 2% HP.
2% doesnt sound like MUCH.. BUT.. bear with me.
2% of 300HP is 6HP
if you drop your intake temp from 200 degrees down to 160 that is a 40 degree drop.
so take the 6HP and multiply it times the 4 and you get 24 HP.
I'm sorry, but 24 HP is "noticable and you can FEEL IT".. and it's a substantial increase in power considering most chip manufacters claim "about 20 hp increase"...
Headers.. 30HP increase
So for the cost of a 300.00 chip.. or a 800.00 set of headers you can almost pick up the same amount of power from a LOWELY 20.00 THERMOSTAT.
Alot people will argue this point, but you have to consider that these people have "products" they are trying to sell, or they just want to argue either way
I'm not trying to sell you ANYTHING and I dont want to argue.... just stating the facts based on my personal experience.
Dyno numbers are pretty subjective, and I dont "race dyno's".
I can go to three different dyno's on the same day and get different numbers.
Whereas I can drive to 3 different dragstrips and get the SAME NUMBERS..within .01-.02 and MPH numbers that are "DEAD ON" the same.
MPH numbers are far more accurate than "some guys dyno" that may or may NOT be using the correct settings.
Dyno numbers are easily fudged by using differnet correction ratios...
Unless you have 3 dyno's set up exactly the same.. the numbers will be different.
I use a REAL TIME DYNO.. "the dragstrip" that tests my car in the exact manner that is it used...
no load factors to "fudge" no correction ratios to fudge.. no BS.. just REAL TIME ACCURATE DATA.
I have timeslips showing the improvements.
I have extensive logbooks documenting these gains.
Do I feel the need to "prove anything"..NOPE.
If you dont want the "FREE HP".. no skin off my back.
For every 10 degree's you drop the intake air charge is worth 2% HP.
2% doesnt sound like MUCH.. BUT.. bear with me.
2% of 300HP is 6HP
if you drop your intake temp from 200 degrees down to 160 that is a 40 degree drop.
so take the 6HP and multiply it times the 4 and you get 24 HP.
Are you guys using the Hypertech 160 degree thermostat?
That being said, about how many tenths did your shave from your 1/4 mile by going to a 160 tstat?
