There is a great article in Motor Trend this month written by Van Tune on page 12. The article goes into great detail about how conditions (baro pressure, humidity, elevation, temp) can influence you car's performance.

For 1000', you loose 3.6% of power on a NA motor

For every 10 degrees, you loose 1.5%

For plus or minus 1-inch change in pressure you gain/loose 3.6% power.


Motor Trend corrects ALL thier times to standard elevation, 60 degrees, 0% humidity, and 29.92 pressure.

So according to Motor Trend, my car runs 14.41@96mph I could only dream.

interesting

I think we all need to move someplace with those exact conditions year-round.

I've always thought it was wierd that the cars they test in the mags ALWAYS ran much better times that the ones in real life. Now I know why I can beat cars that the mag times say are just as fast or sometimes faster than my car.

while i don't believe too much in corrected times this goes give me something to shoot for. even though i had no traction last night with the times i ran i would be into the 13's on a cooler day. and the baro was at like 28 and falling. a storm was moving in. drag radials and fall weather will help.

VQdriver

it's entirely possible! just go out and do it! i ran my best time when it was 85 degrees or so. i wonder what gains my ypipe will give me during a cool night. before my ypipe, i could only extract a best time of 14.6 during a cool summer night. now i run 14.6 on a bad run in the heat! so get psyched to run 14.4s! i need more power.

SithMax

Damn, that's a really nice time you got! 14.6 with just an intake and 14.5 with intake and y!

VQdriver

thanks. the power is definately there and i'm consistently faster now.

Sonic

Uh, at 28, a hurricane would be moving through.

yea i read that article too, its pretty interesting.

i believe it was a high 28 and falling slow.

Sonic

Hurricane conditions.

SithMax

And?

Sonic

A barometric reading in the 28s going into the 27s would mean a hurricane was overhead. I think he means 29s but he won't correct it.

SithMax

If you think that a hurricane is the only thing that causes severe lows then you need to watch more of the weather channel. And even it was 29, who cares? There's no reason to mention it more than once. Cut him some slack.

Sonic

I will sir. Thank you for putting me in line. Now I feel like the BIOTCH that I am.

BTW, do you know Steve, have you ever met him?

SithMax

LoL, where is that smily from?

BTW, nope. I'm assuming you do though and that somehow makes a difference. Whatever. No skin off my nose. I'm just really tired of watching fights break out on the boards. Not trying to make waves.

Sonic

It's my smilie now, its hosted on my ftp account. I VERY rarely get into fights with people, and when it is it is always with someone I know.

SithMax

Well what the heck was going on last week or so with that thread that jumped 7 pages in like 3 hours with you Doug, oh, I mean *SprintMax* and that jerky guy? Sure seemed like a fight to me

ya thanks for sticking up for me, but me and greg do know each other and this is all we do. try to dog on each other all day long. it's fun. It seems like were married because all we do is argue over stupid $hit.

except for me

Synki

Dave B...let me ask you this. Since the best bar. pressure is around 29.xx. What would you say is the best weather to get good times? I drag in summer, fall, winter, & spring. I think the fastest times i produce are in late fall/early or late winter. What would you say?

Sonic

You did it to yourself dude. Everyone else knew to just let it pass.

02BBQ

hey the smile was there, i hope were cool

no free ride for you

Sonic

It's cool.

Dave B

Actually, the higher the baropressure, the more power you will make. The closer you are to the east coast, the higher the baro pressures, typically. I don't know why, but it seems to go that way. Here in the midwest, we are lucky to see baro pressures exceed 30.1, but I've seen some timeslips from of the northeast tracks showing 31-32 baro pressures which is like running at 2000-4500' BELOW SEA LEVEL. I firmly believe this is why nearly all the fastest Mustangs, F-Bodies, Maximas, Hondas, etc reside in the northeast. Running under a 32 baro pressure has almost a supercharging effect on a NA motor. Go over to newcelica.org and you'll see that two guys (the fastest NA GT-Ss) ran 14.3-14.4s@98mph in mostly stock GT-S Celicas last winter in New Jeresy. The conditions were a 32 baro pressure, 40 degree temp, sea level, and 10% humidity. It doesn't get any more ideal than that. Funny thing is, they can't figure out why they are only able to run 14.9-15.1s@93mph now.

Low humidity, low elevation, low temp, and high baro pressures will always produce the better ets......assuming you can hook up.

i think Steve wants to give you one and needs an excuse

Sonic

Hmm, unless Steve was born a female, it isn't happening.
