This is a great forum with loads of information. Would like to see some real ET's to compare to mods done.
I ran my 300C and was somewhat disapointed.

Air Temp - 88 degrees F
Track Temp - 100+
1500 miles on odometer
In Drive, let transmission do it's own thing.
1st Run - 14.850 @ 95.33 mph
2nd Run- 14.814 @ 96.11 mph
3rd Run - 14.846 @ 95.23 mph.

Car is stock. Have Borla exhaust ready to install and Volant intake in the mail. I'll try to post the times after each mod.

Thanks,

Russ

Yes, this would be great to see what ACTUALLY happens rather than an endless parade of 'butt dyno' claims after installs.

I'm sure the 88 degree outside temp was not helping your times out at all, of course I am pretty sure some on the forum have run lo 14's Stock and close to 100 mph for a trap speed. That is strictly from memory though. My understanding is the best runs are done with ESP off, throwing the tranny in 1 and power braking to about 1500 RPMS

Welcome Russ. Great first post. Timeslip, no less!

Lot's of good info and great folks here.

Enjoy!

Looks great, but what were the barometric pressure and the altitude adjustments? We need to know those also for any later pass so we can compare apples to apples

Russ you're the kind of forum member we need

It would be great to add the Volant first - then run it

Then add the exhaust next - and run it

Those two sets of #s would be really interesting to compare with your stock #s

All - Thanks for the welcome!!

jcsganga34 - First run I used power braking (about 2000), 2 & 3 just gassed it. A little more wheel spin without power braking, but ET no different. Didn't attempt manual shifting because I'm looking for a baseline.

NR - Yes timeslip. Runs approx 30 minutes apart. Didn't list all the intermediates. Did get a .101 RT (not bad for grandpa, but won't mention the other two). Should have run the week before (50 degrees and 10 mph tailwind), but was helping my grandson.

mspeas - Here in Orlando we are at SL. I forgot to get the pressures, but in this bracket, probably only worth a few hundreths.

zilla - The Borlas are here and the Volant should be here tomorrow. If I'm working alone I'll do the Volant first, but if my grandson is available, I'll do the Borlas (2 person job)

All - Again, thanks for the welcome.

I can understand SL in Orlando. But, what I mean is altitude adjustment for whatever the barometric pressure is. You may be at sea level in real time, but in barometric pressure you may be at 1000 feet. So whenever you race the next time that has to be considered for any E.T. correction. Hence my statement of "apples to Apples".

mspeas - As an ex flight instructor and military avaitor, I understand the relationship of pressure/altitude (approx 1"/1ooo ft) and will record it next time. Typically this time of year dosn't change much (usually 29.8 - 30.2). I forgot to mention that I did record RH at 66% (affects air density) which has a slightly larger effect.

At any rate, if these products do what they say they'll do, I shoud see it in the ET's

May not run this Friday, but for sure next Friday.

Have a nice set up here in Orlando on Friday nights. Cost $10 per person, + $5 to run. It's sponsored by the Sheriff to keep kids from racing on the street. No classes and with the typical amount of cars, trucks, bikes you can run about every 1/2 hour between 6:30 PM and 10:30 PM. Six staging lanes, so real easy to grudge race or put a little money down.

Now that is what we need in Central Illinois. However its still a little cool here (47 degrees) for racing just yet. We should start in a couple of weeks.

Russ, Great to have another Hemi owner who is willing to make a pass or two. N.H.R.A. uses altitude correction factors to establish National Records which may have been set at different tracks. There is no correction factor used up until 1200' above sea level. Density Altitude Correction factors are used by Bracket Racers trying to dial their cars in to run the same number(within 1/100) on different occasions. Obviously, when comparing the performance of different cars on different tracks it is necessary to try to equalize the conditions and eliminate variables. But where I find I doze off is when I hear people say "I went 15.50, but I really would have gone 13.90 using XYZ correction factor or under other conditions". I don't know about you, but I much prefer racing cars than computers and math tables.

QB409,

I agree with you, being an old "60's", "Class" Drag Racer as I am. Back then it was all heads up and he who got there first, WON. Today with the brackets its as you say "computers and math tables".

Sorry, I like the old way also.

Old School Super Stock

Mike, A 60's class drag racer, I have got to hear more! Any photos from the day that you could post? What class did you run? Any info would be appreciated. I have a great book that you would enjoy, its called "Super Stock - Drag Racing the Family Sedan" by Larry Davis. Lots of Day 1 photos and excellent history. I missed the party the first time but have relived it recently. Tried to explain to my not so old insurance agent details about my 62 Chev Bubbletop 409/409. Finally gave up and said "you know, the Beach Boys car-a 4 speed dual quad positraction 409". Just so members don't think we're a couple of old school gearheads getting off topic, there's lots of useful info that was learned by staring at that last amber bulb that is relevant to a new Hemi owner , even if the new cars do have 9 onboard computers.

First time out my Magnum went 14.22 at 99 MPH, factory stock. I am convinced the car has a 13.90 in it, no correction factors necessary. QB

Don't mean to highjack this thread but you have a Bubbletop? Very cool! It's one of my favorite cars of all time. That's a great book and should be required reading for anyone even halfway claiming to be a gearhead. This is my current version of '60s class drag racing. The Super Stocker is mine and the injected hemi AFX car is my brother's.

Those are two great cars! There's something about velocity stacks that just about does it for me. Sold my bubbletop 2 years ago to a guy in Scotts Bluff Nebraska. Wish I still had it now. But there have been a few other big block Chevy musclecars since then. I am a Mopar convert now, and I'd take either one of your cars in a minute. With all the controversy about 2 vs. 4 doors on the Charger, I just say to the critics, go and drive any Hemi powered LX car and tell me it dosen't remind you of the good old days. I just call them "Four Door DoorSlammers". QB

QB409,

So you're "convinced that the car has a 13.90 in it". Do you know that my D/S Junior Stock 57 Belair that was not a daily driver<G> in 1964 ran right on the then National Record of 13.92E.T. @ 104MPH. That was with 5.57 Gears, 7" slicks, 4-speed and an Rochester injected .060 over 283 and we sure didn't drive it to the strip. That car (and still is - I still have it) was at that time 3227lbs factory shiping weight. Today your (mine) 300C at almost 4500lbs runs just as fast and you (we can) drive it to the strip and get 25MPG getting there. I, along with all of my friends, felt that when they killed the muscle cars of the 60's that the HP wars were all over. And they were for almost 30+ years. But now they are back and look what we are getting. The SRT-8 (getting 19MPG - don't remember the 60's cars getting that kind of gas mileage) and all of the others out there. The Cad's, the Vetts, the GTO's, the Mopars, (were the HELL is Chevy?) and all of the hot so called "imports". God it's great to have been in both the 60's and now.

More war stories on demand<LOL>

Mike

P.S. AWD 300C,
Very, very nice. Didn't like Mopar back in the day, because I had to run against them. But its different now, I drive one<G>. GM is not building a Chevrolet sedan I want since they stoped production of the 96 Impala Super Sports.

Thanks! Yeah those stacks draw a lot of attention. When we go to car shows together I insist on driving in first. If I follow my brother's car, no one ever sees me.

You're right Mspeasl, we're lucky to have experienced both eras of Horsepower Wars. It's a great time to be a car nut!

Today I installed the Borlas (140112). I put the back end on ramps and the job was easy (about 1.5 hours) with the help of my grandson.

Then took it back to the track.

Air Temp - 85 degrees F
Track Temp - Unknown but estimate about 100
RH - 46%
BP - 30.01
Slight headwind of 10 mph about 20 degrees off nose.
As before, just ran in D with ESP off (tried both on and off, didn't seem to matter).
1st Run - 14.697 @ 96.64 mph
2nd Run - 14.642 @ 96.43 mph (RT .013) brag brag
3rd Run - 14.662 @ 96.28 mph

Seems the Borla took off almost .2.

Next I'll install the Volant and run again.

Russ
