Actually it does. Up to about 10-15 degrees difference in tests I have seen. Contact DaveO or MotorDyne to find the details of those tests. I did it also myself with a Craftsman Laser Temp gauge and I was surprised of the difference with one on and off. It HOLDS the heat in more with one on.

If you remove the cover, I would also recommend cutting the rubber molding around the back of the engine comparment in the center and spread it out to the sides so it allows air to flow out of the engine compartment to help cool everything as well.

Please trust people who know this car better than others and who have tested it many many many times in different conditions. That is why mentioned the two above.

 

Wrong.

 

Well your results obviously are skewed. Especially since there are many other tests that show it gain heat with it on.

It's only common sense that removing the cover will release the heat that is trapped and allow it to have airflow over the intake plenum.

 

Whatever you say, Chief.

 

interesting

 

When I tested it myself, there was no difference.

Guess we are both wrong.

But since all you and "Earl" care about is jumping all over DaveB, what would you care about my tests

 

And how did you test it? What equipment did you use, what kind of driving conditions, etc? Please show us.

Like I said, its common sense the engine cover does not help and it does hold heat in. Removing it allows air to flow over the engine so it will decrease the temps.

 

Do you honestly think a drop in temp of 5 degrees on scalding hot 170+ degree intake manifold is going to make a lick of difference in terms of performance? Have you ever done back to back passes with a G35 and noted the difference in trap speed between a scalding hot motor and a cold motor? I'll give you a hint....there's no difference in trapspeed. Trapspeed = available power.

 

i forgot to mention that, in retrospect to my previous post, my top plenum is just slightly warm to the touch w/out the cover on on my 2 hour drive home from fresno to elk grove (alot cooler than when cover was on)... this is coming home at nearly the same time and with same external temperature both on both instances with and without the cover on.... so yeah, i can honestly say than it'll run cooler with cover off...

 

Yes more proof that its cooler. Unlike a few here who have no clue how things work.

 

When Tony and DaveO actually decide to test their mods at a track, I'll then accept thier findings concerning the performance of running with or without a cover.

 

Track does not equal to DAILY DRIVING YOU IDIOT.

Track IS NOT A TEST for HEAT of a engine cover. It helps for daily drivability when you do stop and go. Wow HOW STUPID ARE YOU?

 

Seeing that track driving is the most extreme type of driving concerning engine heat soak, I'm uncertain as to what you're alluding to when it comes to "daily drivability". My track and data log tests show proof that the cover does nothing to impede power production. Isn't power production the purpose of this so-called mod?

What's suppose to work in theory does not always apply to the real world. Nuf said.

 

Enough of your clueless one bs.

 

Same old response. Absolutely nothing to back up your claims. Only weak-*** reponses.
