good infoomg i had a realization, the brand from autozone is ValuCraft.
it was like 15 bucks.
they ask me for make/model... i tell em, they say they got nothin for tstats.
i say ok type in "4128" for your part number. and it pops up as valucraft tstat. thats the one.
when you open it up, the actually tstat inside the box has the words "motorad" etched in it on one side, and "germany" in it on the other
Yeah some guys ran some logs with their Super chips and saw that once the coolant hit 195 the engine started to pull timing.yep tstat will keep your engine cooler, allowing for more power. our engine respond VERY poorly to heat. example at 180 degrees I ran .4 faster at the track than at full temp. ive heard that once you get above 195 degrees or so you loose about 20-30hp
the stock one is 204 i belive. i have a 180 t stat now and I promise it makes a diffrence. go out and floor your car when its at 160-180 degrees. feel how fast it goes. then drive it around for a while and let it get up to full temp 220-230 w/e it gets to. drive around and get good and heat soaked and then floor it. you WILL notice the diffrence.
You still need to do the fan mod for summer driving. Otherwise the fans still dont turn on till you hit 219 or so. Winter driving the car will never see over 200. Here in PA it runs at 185 in the winter, and with a fan mod of some sort summer driving I can keep it in the 190's to 188 in traffic. And yes... the car is much more aggressive with a cooler block.
