Does anyone know if the 160 degree thermostat offered at lingenfelter will work with the supercharged lsj motor

 

Every time this topic has been brought up, it's been shot down. There is no actual gain from using a lower rated T-stat on these cars. PM qwikredline for more input on the topic.

 

Joe's right, lowering your coolant temp does nothing beneficial for the car. I believe it will actually make it throw a CEL for abnormally low engine temp.

 

if you can keep the ECT lower, it should yield gains. It's possible that PCM tuning would change and cost you power but all things being equal a colder motor will make more power. This would be especially true on the LSJ where the IC resides in an aluminum housing bolted to the block and IC fluid is being warmed by the engine.

 

Tell it to NASCAR. F1. NHRA (dont even run coolant) cold motors = less power. Car runs on the T/Stat as it is. Give up you wont find a 160 T/stat anyway...

 

Im assuming then either the gas or something else is different to help with pre-det?

 

I can't understand what you're saying.

im pretty sure zoomer is actually right... however, gains would be VERY minimal (like a couple HP) at the cost of reducing your engines lifespan a good deal. you would see a very minimally cooler cylinder, which would allow maybe 1 more degree of timing to be ran.
to summarize: no, there is no point in doing it, and no one recommends it

 

ideally you want to run an ic engine as warm as possible without overheating which causes the engine coolant to boil (at about ~260F).

running it as warm as you can makes the engine as efficient as possible and yields the most power.

 

What, maybe I'm not following you correctly. But the IC fluid doesn't even go through the block.

Yes the intercooler is located in the mani attached to the block.

OP > You can run slightly lower than 180* water, but not too much. Aluminum blocks tend to make best combustion around 180* water temp. I found luck in lowering into the mid 170s by drilling 3 small holes into the stock thermostat and setting the fan speeds and temps on at different than stock rates.

 

There is an optimum combustion temperature for every engine. Lowering the water temp in these cars I don't think would help any.

 

Oh sorry.

 

 

No gains. GM designed the motor to run at this temp, period.

 

simply put... run the car hard without it fully warmed up... then let it fully warm up and run the car hard... take notes.

my car runs it's best at normal temp, around 176 - 179. lowering your intake temps will help, but the coolant? not so much.

 

This isn't NASCAR F1 or NHRA...

 

this is exactly what ever one needs to get in there heads.. when u go jackassing with everything on ur car..**** starts to break and then u think to urself how could this of happend?? nascars drag cars and nearly anyone that can go fast usually runs just pure water in the coolant systems. water is the best heat remover and works great on the ic setup in our cars.. even water wetter helps. if u wanna help keep it from getting to hot in the summer. note ( use coolant in the winter and dont forget to check ur blinker fluid)

 

blinker fluid...lol

 

WaterWetter WILL NOT cool your IC temps unless they're hot enough that you've already likely blown something, it will help lubricate the system though. WaterWetter will help you get more uniform engine coolant temps, I found that with 50/50 + WW I run in the upper 160's when its cold out and around 180 on warmer days.

 

how can your coolant temps be lower than mine? mine is consistently around 190?

 

i think the two cars have different thermostats. Most of the 2.2's i read about have temps around 190-200*, whereas most of the LSJ guys have temps at 175-185*

 

you will actually make less power with a colder thermo on the lsj than with a stock thermo.

 

i have a 2.0, you have a 2.2 When i had my 2.2 it ran a good 10 degrees warmer on average.
