"Feel like lending a hand? I know the NHRA offers correction calculations based on weather factors. As you point out, the info is available. All thats needed is a location (Sacramento Raceway), a time (see the table) and date (10/21) and you can find all the info you need for the calculator. I don't have time in the near future to do so... I'd love a helping hand on this..."

I'll see what I can do. Keeping track of the weather is the next step in my bracket racing adventure.

For those with an interest, please check out the new HELP NEEDED: Dragstrip Altitude/Weather Correction Formula thread I've created.

Thanks.

[QUOTE=CoolVanilla]The 20" tire/rim combo measured 1/2" or so larger in diameter than the 18" stocks.

If this be the case, there can be only one logical explaination. These cars are apparantely the bastardized, in-bred offspring of a previous MOPAR, "Christine". These cars defy science, logic and conventional wisdom and have the ability to reduce or reverse the affects of most modifications from what I've seen.
The good news is that someday if your car is vandalized it will not only be able to repair itself but also track down and destroy the perpetrators. Look for this post coming soon!

Density altitude in Sacramento on the day of the testing.

Time .........DA in feet
8:50AM....... -103
9:50...... ......149
10:50 ..........492
11:50.......... 826
12:50 .........1045
1:50 ...........1206
2:50 ...........1298
3:50 ...........1309
4:50 ...........1309
5:50 ...........1194
6:50 ...........635
7:50 ...........423
8:50 ...........298
9:50 ............162

This data might be useful for comparing any subsequent runs at the strip.

ROFLMAO! :D

Finally got caught up enough on business to have some GIFO3 numbers and input to offer:

GSM mod: All runs, dyno and track, were made with the GSM torque mod on and and the fan switch on. Unlike Matt's torque mod, which is quirky and undependable, mine works perfectly each time. Whether it lowers E.T.s is still debatable, but it does give me full control of my car, allows me to do the precise amount of tire-warming burnout I choose, and, on a good, grippy, track, provides just the amount of wheelspin I'm looking for. My runs were consistent, and were respectable.

The cockpit-controlled GSM fan mod provides a tremendous advantage. Despite repeated back to back runs my coolant temp was never above 160 degrees as I staged, with 6 runs made Friday night and 9 on Saturday.

Here's the event breakdown:

1. SVS dyno: My best horsepower & torque numbers: 288.7 @ 5304, 304.8@ 4414

Test results:

A. The Racing Sports Akimoto Funnel Ram air filter seemed to prove the old adage that there's nothing like cubic inches - in this case air filtration area. Filter length choices for the Funnel Ram filters were listed as "6 inches" and "9 inches", but no charts showing precisely what was measured were found. Accordingly, I ordered the "6 inch" filter as the existing K&N RF-1014 filter measures 7 inches, measured at the filter material itself, and barely fits into the enclosure.

When Jason arrived at SVS with the filter, which I'd had shipped directly to him, it became obvious that Racing Sports Akimoto measures the entire component, which includes the mounting snout. Thus the filter element was significantly smaller overall than the K&N, with much less surface area through which to draw air. As a result the approx. 4hp loss with the small Funnel Ram filter element was surprising only in that it wasn't larger.

We hope to provide the 9-inch Funnel Ram filter for testing at GIFO4. That is Racing Sports Akimoto's largest filter, and if it can't keep up with the K&N filter element, then we can get that word out and save folks some money.

B. I tested another component that I'll withhold more comment on till CoolVanilla has time to work his magic analytical powers on the numbers.

2. Sacramento Raceway, Friday, October 21, 2005:

Best RT: .136
Best 60': Inop all night
Best 1/8: 9.063 @ 77.426
Best 1/4: 14.099 @ 98.896

3. Sacramento Raceway, Saturday, October 22, 2005. MOPAR MuscleCar Magic - nothing but Mopar iron allowed, with very few exceptions:

Best RT: .042
Best 60': 2.082
Best 1/8: 9.073 @ 77.644
Best 1/4: 14.103 @ 99.216

My 5.7L ran consistent 14.1s till the temp got into the mid- to upper-80s, then 14.2s for the remainder of the day. Made it to the final four dozen or so cars from the several hundred initial entrants (3rd round of bracket racing) before getting snookered by a blatant sand-bagger. An overall outstanding experience though, with the muscle cars I'd grown up with from the 60s & 70s in abundance. The smell of nitro and rubber, as the ground literally shook from the thunder of these magnificent original Hemis, took me back to the glory days. I get chills now simply recalling it.

A huge thanks to Jason, our one and only CoolVanilla, who put this all together and made it happen, to Matt Robertson who lent his support, knowledge and good cheer to the entire event, and to DiamondRMP for not only a smokin' deal on his R/T rims

, but great camaraderie and insightful analysis of the dyno data throughout the testing.

Sign me up for GIFO4, CV, I'll definitely be needing another fix by then.

CoolVanilla,

Is the correction factor input before each set of runs?

What determines the correction factor? Is it just temperature?

**diamondrmp** · 10-27-2005, 11:30 AM

It was great meeting everyone and exchanging ideas and thoughts. I'm looking forward to GIFO4!! By then I should have my Magnum back.

**BrilliantBlackHemi** · 10-27-2005, 05:56 PM

All you guys are awesome for putting all this data together. We'll try and make some more in Englishtown Saturday.

I see you did this in Sacremento, is the session open for visitors? I'm down the road in Modesto and would really like to learn more (and see & hear) about other Hemi's . . .

**diamondrmp** · 10-29-2005, 11:49 AM

As far as I know it is open to anyone that would like to come and mingle.

That's correct. CoolVanilla always issues a fully open invitation to one & all to attend.

**MattRobertson** · 10-29-2005, 01:56 PM

The more the merrier!

**Meister** · 11-01-2005, 02:07 PM

CV asked me to let everyone know that he'll be back in stride with further analysis & results of GIFO3 testing in a week or so. Business and family commitments have had him overtasked of late.

Safe travels, friend. 'twil be good to have you back.
