Congrats to Mr. 5!!!

What do you think the times and MPH would be if you were running an auto with your setup???

The manual with CDV delete, racing clutch, and LSD can be a very potent combo!

[stressdoc]

With the right software tweaks and a hotshoe driver its manual tranny ftw. Until we get DCT.

I was talking to Terry about this and we think that there would've been probably about 2 tenths off of the time.
I haven't had a chance to look at my shift times but I'm assuming that they were about .3 of a second and I shifted 3 times. If I had an auto, the shifts would have been .1 second, but incorporating gear ratios and other things, we think that .2 off the time is reasonable.

What about MPH???

It's funny too how the first time I hit 11s, I hit 11.80!
The DA was about 1500 ft.

Here are my mods:

-GIAC Stage 2+
-Snow Performance Meth
-Approximately 103 Octane
-AA IC
-AE Exhaust with High Flow Cats
-Macht Schnell Downpipes
-Macht Schnell DCI (still in production)
-Wavetrac LSD (You gotta love the traction!)
-ACT Clutch (This clutch is rock solid! No hickups or slips whatsoever)
-275/40 17 Hoosier Drag Radials (Special thanks to RacerX for letting me borrow them!)
-Back Seats out, Passenger Seat out

So, I'm thinking that this makes me the quickest 6MT to date.
Anyway, below are my slips.

Here's the vid:

Congrats Craig..... watching your car go quicker and faster down the strip was incredible. You are one heck of a driver

By the way, I had two hand-held weather stations with me all day and there was a noticeable variation between them. This is what I record on Saturday:

10:00 am --> 700 to 750 ft with 60% humidity and 55 F temp
11:00 am --> 800 to 850 ft with 50% humidity and 58 F temp
12:00 pm --> 900 to 1050 ft with 45% humidity and 60 F temp
01:00 pm --> 950 to 1050 ft with 40% humidity and 62 F temp
02:00 pm --> 1050 to 1100 ft with 38% humidity and 64 F temp
03:00 pm --> 900 to 950 ft with 36% humidity and 68 F temp
04:00 pm --> 800 to 850 ft with 40% humidity and 64 F temp
05:00 pm --> 750 to 800 ft with 45% humidity and 58 F temp

As you can see, at Famoso, temps and DA drop very rapidly after 4:00 pm. That's why I usually like night sessions more than morning sessions Unfortunately, DA was just not as low as it was in the end of November (100 to 200 ft)

So looks like the Dragtimes 833FT DA listing is about 200ft off. I usually just use that because its convenient to check different tracks in the nation. Unless the Drag times is EST, which would mean 11am which is nearly identical to what you have listed. (800-850DA, 58F)

"Looking for maximum horsepower for your 135i or 335i? Our 135i made 440rwhp / 426rwtq using the JB3 with a race gas map, Riss Racing downpipes, Riss Racing catback, Code3 intercooler, and the BMS dual cone intake. Staggering 175hp gains at the wheels, or almost 225hp at the crank! This map powered our 135i to 1/4 mile times of 11.8 and trap speeds of over 120mph! The worlds fastest N54!"

Mmmm, both 11.8s. I wonder how equipped that 135i was.
how much tq and whp are you putting down mr.5?

[ultimateracing335]

I don't know how you don't break half shafts with the manual. As soon as i get on the power off the line they snap. Is your car lowered??? Maybe my car is to low??

[Mr. 5]

I was going to talk about this because I think that the actual DA is one of the most confusing things and I think a lot of people get this wrong.
Mo, I don't know the way your meter calulated the pressure, but I was talking to my friend who's meter I was borrowing and he explained everything to me.

First off, the meter that I borrowed was a $600 DA calculater and it is extremely acurate and this is where I came up with an average of 1500 ft above sea level. I was wondering if it was wrong during the day but I didn't know exactly how it was working. Now I know.

There is a difference between relative pressure and actual atmospheric pressure.
Relative pressure is what weahter stations use to see if the pressure is above normal or below. 29.92 is the baseline of every area since that is the actual pressure of sea level.

Actual pressure is exactly what is says. It's the actual pressure for that particular area. Weather stations don't use this because they "normalize" their area to the relative pressure, which is 29.92 (sea level).

Example:

Denver is about 5000 ft above sea level. Going by the chart in the link below, you will see that the actual pressure in Denver is about 24.90, but if you go to weather.com, you will see the pressure listed at 9:45 Denver time is 29.97.
http://www.engineeringtoolbox.com/ai...ure-d_462.html

If you use the 29.97 for the DA calculation then you are going to get an extremely wrong calculation. Sicne 24.9 is actual and 29.92 is the baseline, then you can see that 29.97 is .05 higher pressure than the normal so you would add the .05 to the 24.90 making the actual pressure right now as 24.95.

So...After all of this explanation, the sea level for bakersfield is about 500 ft above sea level making the actual pressure aproximately 29.38.
My meter was displaying 29.32 so it looked like it was close to a normal day.
29.32 should be used in the DA equation and not the numbers that dragtimes dictate.

Mr 5, how are those carbon brake pads doing. can you update us?

That's BMS' auto135i. It's done a best of 11.72 at around 122-123mph at Fomoso with cats. In that trim it put down 432hp to the wheels. Several of BMS' customers are quicker though, and one even faster! Granted the MPH was at Sac so its questionable.

[Kroy]

great results Mr. 5. Congrats!

The last dyno that I did was about 426 whp and 435 wtq, but the race gas should bump it up a little more.
I almost hit 400 whp on a mustang dyno.

In my experience, Dragtimes' DA and temp numbers have always been off. It collects data from the nearest available airport, which could be as far as 5 miles away if not further. It is always better to collect data on-site directly from the track to get a more accurate number.

Craig, thanks for the explanation above, it certainly clarifies some of the mystery behind it

Regarding the devices I used, I actually used 2 different hand-held weather meters. One was $350 and the other was over $2,000. Both came with certificates of accuracy and required paperwork, yet both gave a noticeable variation in numbers However, I continued to monitor the weather every half an hour throughout the entire event.

Also, please note that Bakersfield is at 300 ft above sea level and the track is in McFarland (24 miles north of Bakersfield) which is 615 to 635 ft above sea level. But even weather data collected from McFarland's weather station relies on info from Bakersfield. The temps in that area vary greatly due to the vast fields and random winds in the area. When I left the track and went to lunch, the temps outside the track (just 1 mile away) were nearly 7 degrees cooler with lots of clouds and there was no sun (very opposite from the track).

In the end, DA calculation should be used as an approximation at best. I honestly think that even if we use two identical devices of the most expensive model, we'll still get a variation in numbers To reduce some of the inconsistency, I think the same method should be used consistently.

Anyways, it was a pleasure seeing you run and break records at the track Craig and hope you continue to raise the bar. Your car is a beast Your next step should be Sacramento anytime from November to December with DA of -400 ft

what RPMs did you launch at and what were you shifting at?

Yah, I wasn't questioning the acuracy of your gages but I am interested in what is involved with determining the actual DA.
I appreciate your responce.

Ya see, for me...I've had it all wrong all along. I would get a standard DA calculator that I would find online and enter numbers that I would find on the weather.com web site. I would usually get a really low DA but that was because I was entering the relative pressure instead of the actual pressure.

Thank you very much Sir, and I really appreciate you setting up these track days. I would absolutely love to destroy the pavement at Sac!
Hopefully I'll have the same car though because I just passed 67,000 miles.

I was launching anywhere between 3-4k rpm.
I think that you can see the rpms climb to about 4k in the video.

Oh sorry.
I only saw the launch question.
I was shifting at around 6700 rpm.

the same for all three?
1-2
2-3
3-4
