Finished a swap of a 195 stock thermostat to a 180 degree thermostat today. Had to do it two times to seal it right and I thiiiiink that I may have gotten some more power from the warm engine. TRhe current MM and FF said that I could get 4-6 hp from this easy swap. The only difference that I notice is that MAYBE I changed in speed to rpms. I was at about 2000rpms- 60 mph and now at 2000rpms to around 62 mph. I said MAYBE. Does this sound right at all to anyone???

 

The engine speed to vehicle speed should not change since it is directly related to gearing not engine power. You probably do have a few more hp however.

 

I dont know but my car is different now. I t may just be in my head but it seems like it idles rougher. ANyone have a similar experience????

 

no other takers???

 

i just went to a 180degree thermostat and im my car is running cool and strong. i also went to a hi flow pump though too.
