My reasoning for handling you like this is your flagrant disregard to consider or view proven information.
Your supercharged motor is running on 90 octane with no KR. Have you checked the timing tables? Why do you ask? Because your pcm most likely has you running on low octane tables, making minimal power and using more fuel in the process.
In the NA motor a higher combustion temperature increases the EGR temperatures and heat cracks the thin wall between the cooling passage and EGR stovepipe much quicker. This then fills the motor with coolant. The supercharged motor does not get effected by this and therefore..you won't get he pleasure of destroying your motor with your advice, only someone else'*.
Somehow I feel that you would tell everyone here that the lower intake manifold gaskets don't degrade in the Series 2 engine running Dexcool as well. Lemme give you a wake up call pal....you've thoroughly pissed me off and now you get to hear it.
Lower intake manifold gaskets on Series 2 degrade, dexcool speeds this process.
An NA motor as well as an SC'd motor benefit from running 10-15 degrees cooler.
Our cooling systems can keep up perfectly fine with a 180 T stat. If yours can't.. clean the system...it'* probably plugged.
By running your 90 octane fuel, you might think you have no KR...if you scanned, which I am doubting at this point...you would find your timing is most likely in the single digits. That'* why a Yugo passed your supercharged car yesterday.
Dude, relax. He'* got some legitimate points...a lot of the same ones I brought up in my thermostat thread.
I don't understand why people are getting so heated over this...there are some good questions being asked which nobody cares to answer without complaining that we're not acknowledging "proven information". I joined this forum for educated/curious discussion...anyone else feel the same?
I hear people talking about the great gas mileage they get with 180 degree thermostats...but no comparison to gas mileage with 195 degree thermostats. Nothing proved!
I hear people talk about ranges of thermal expansion and their effect on wear. At low temperatures the engine components haven't expanded as much. At high temperatures they expand too much. It seems the happy medium has been placed arbitrarily at 180. Maybe 195 is ideal? Nothing proven!
I hear people talk about hotter thermostats being strictly for emissions. As far as I know, none of them work for GM. Nothing proven!
It'* not that I don't believe you guys...I do! You have far more experience than me regarding the 3800. But the reason I'm asking my questions, is I want to know why it is the way it is. I'm looking to see if anyone has data they can compare...or any real comparative observation to share. I'm after the explanation
more than the answer
, but the answer is all I'm getting.
