I have had on of these G-Tech meters for about 6 months now....When I first got it I tested my truck in approximately 60-70 degree temps and ran consistant 4.7-4.8 - 0-60 and 13.1-13.2 1/4 mile with a best of 12.8.

I decided yesterday to play with it for just a bit and I was running 5.5 0-60 and ran one 1/4 mile and ran a 14.0. That is terrible times for a truck with my mods. It was 92 degrees outside, so it was pretty hot, does heat make that much difference??

I would think that I should be running high 12's - low 13's at worst. Can you guys help me with this....Thanks!!

 

Well I was at the strip yesterday and the best I could muster with mostly a stock 03 L was a 14.05. It was 86 out..... There was another L owner there, Arron, and he was running in that area as well. He said the last time he was out he was running 13.7's. So I think the heat is a big factor.

The heat really saps the power on my stock L. I used to own an '88 Mustang 5.0 with heads,cam, intake..... and a Vortech, and the heat really killed that car too. I believe supercharged engines in general lose a lot of hp in the heat, but the L and the Stang are my only personal experiences.

 

Its more the humidity. When the air is full of moisture due to humidity, there is actually less of it to use for the blower. When the humidity is lower, their is more air for the blower to use hence more power. Wait until the fall comes and that crisp nighttime air returns. Its like getting a new mod.

 

Forced induction motors lose about 2% of their power for every 10-degree increase in ambient temperature. Normally aspirated motors only lose about 1%.

The best race weather for our trucks is:

50 - 60 degrees ambient temperature
Barometric Pressure over 30 in.
Humidity below 75%

Ambient temperature and power are indirectly proportional. Ambient temperature and traction are directly proportional.

Ya Hoo

Let's see it is 92' and about 97 % humidity out here in South Florida so when fall come I can look forward to an 8-10% increase in my allready tire shreading performance.
