New Best @ Atco Tonight

[DLF]

@ Cecil County Dragway, MD today.

No DA data currently available, but it sure as hell wasn't negative.

The A/F ratio in the tune still isn't right in 1st gear, but the TC now locks right after the 1-2 shift.

Hmmm.. you'll be knocking on the door of 12's here shortly at this rate Doug.

 

[slowmkviii]

Very nice
i like the fast progress.

 

[KStromberg]

That's a hell of a trap speed!

Congrats on a new best, that is definitely a record MPH for a bolt on Mark VIII. What tires are you running, your website says Firestone street tires?

Thanks!

MT 275/40-17 DR's on 17x9 M179 Cobra R's @ 25 psi.

I also forgot to mention that the race today had a 4,000 lb. minimum weight, so I nearly a full tank of fuel, and my race weight was a bloated 4,065 lbs.

So when are you deleting the A/C and doing the Meziere Water Pump? And can you make the Mark as fast as the SC?

The A/C isn't going anywhere. And I'm not going to bother with the electric pump.

I'm not finished with my SC either, so probably not.

Here's a link to a video of the 13.22 pass:

Man that thing looks fast. Are you still powerbraking it to 2k rpms at the tree?

Well, it is!

Yup.

And this should probably put to bed the "Gen 2's are slow" notion.

Time for a short runner intake and some weight reduction...

 

[KStromberg]

I'd rather see him run 12s in full street trim.

I'm probably not going to go to a short runner on this car. Certainly not with the stock intake cams. Maybe after I swap in a T-56, we'll have to see.

With my normal race weight of ~3,980, a few more tweaks to the tune, and some good air, it'll make it into the 12's as it sits.

I believe that the DA today was somewhere around 1,200 ft., although I can't prove it. That would make my corrected ET around 13.05.

I would really love to see some in-car videos of your car Doug at the track or in Mexico.

I thought about deleting the A/C but, not such a great idea in the summer, with a black car, and black leather. Plus, I don't see a point in doing it, as I believe the pulley on the A/C spins freely, then when it turns on, the clutch engages, and that's when parasitic drag happens. I could be wrong, but that's how I feel. :shifty:

I always use airdensityonline.com to keep track of DA.

MOST Gen2s are still slow.

 

[98LSC32V]

MOST Gen2s are still slow.

Gen 1's are slow too. Any car that runs high 14's stock is pretty slow these days.

I only see forecasts on that site, not history. Am I missing something?

Yes unfortunately no history on their site. But it's helpful on race day.

Well, since I've never seen a higher MPH posted by any other stock block N/A Mark VIII, I'm going to go with all of the other N/A Mark VIII's are slow.

 

[driller]

... I'm going to go with all of the other Mark VIII's are slow.

Not all of them get to run downhill...

with a tailwind.

Look here for weather data.

 

[DLF]

Hmmm.

I seem to recall that the #1 car on some list did that very thing.

 

[DLF]

Look here for weather data.

Using data from that site, for the MAT133 station, at 11:15 am the conditions were:

70 degrees
30.17 pressure
44 dew point
3 MPH winds, gusting to 4 MPH from the WNW.

The DA calculates to 971 feet.

My ET/MPH corrects to 13.094 @ 105.927 using the calculator on Drag Times.
