Heat information

[MMarauder03]

I'm running my stock mm with just exhaust work done today at 600 ft. The heat is about 110 on the track 50% humidity, how much slower will my mm run compared to better conditions... Say 75 no humidity give or take? Anything I could do to keep my mm running faster?

as to how much it will slow down your car I do not know each engine and how it reacts is differnt.

But what you can do to help the situation is find a way to cool the fuel down and you can also run water injection into the intake to help cool the air down as well.

We use to run the fuel line through a make shift ice bucket and we would fill it with dry ice to cool the fuel before it got to the engine.

An extra cool fan in front of the radiator might help you out as well.

The correct answer is:
Go back at night when its not hot.

You are merely wasting your time. Atleast in my car you would be.

Here you go. Read up on Density Altitude and Dyno Corrections for temperature and air density>>>>>> http://wahiduddin.net/calc/cf.htm

I did a quick DA for your 110*F/50% humidity and assumed a dew point and barometric pressure. Answers was DA = 5281 feet.

At the 75*F and "near zero" humidity (you don't get to zero even in the desert), the DA = 2901 feet. I'd say that the current 110*F & 50% humidity conditions will degrade performance significantly.

You are welcome to do the HP/Torque conversion factor for yourself. :D

I use this site, does the calculations for you, just pick your track and date of the event and it keeps a database of weather info.

So running in the East coast's hot humid weather is like drag racing in Denver Colorado...:eek:

First time I ever ran my mm. I was running 15.40's consistantly at 93.33 or 93.36 mph trap speed. Beat a twin turbo Nissan 350z that must have fallen asleep on the line! His r/t was 5.7 seconds. Lol. I corrected it for my last run at 98 degrees 45% humidity. So i would have run a 14.75 all stock for now minus my muffler swap and cat delete. Could have done better but I'm dead set on gettin boost now!

Weather Conditions .75 second difference from best to worst.

I've been itching to hit the track since having 4.10s installed but I will wait until it's in the 70's at night or fall/winter. No sense in running in this hot humid weather and put more wear on the car.

I'd be interested to see your run with the 4.10's. I watched all of your videos when I was considering purchasing my MM :beer: I had to run it just to see my base times for future mods... tune coming soon. :D

Thank you kindly :beer:

Trust me it's itching at me pretty badly to run but I want to get another driveshaft with fresh hardware before I start launching the car hard.

I'm hoping to get another 0-90 vid up soon.
