Quarter mile times vs. engine type and power output?

The question posed was what are your actual times and what are you running to achieve those times. It seems no one wants to post that information.

The following are the numbers you requested for the Gobra with all the details:

My engine is a 427 cubic inch small block (Roush 427 SR #444) with 525 dyno horsepower and 525 foot pounds of torque on a Roush dyno. The transmission is a Tremec T-56 and my rear end is a 9 inch Ford with 3.89 gears. The drag tires are 17 inch Hoosier Drag radials. The car weighs 2720 pounds with me in it.
Here is my best 1/4 ET of the day recorded at the Shelby Nationals in Tulsa in 2011 with an ambient temperature of 104 degrees F and thousands of witnesses.

60 ft. 1.5 sec.
1/8 mi. 6.86 sec.
1/8 mi. 101.8 mph
1/4 mi. 10.56 sec.
1/4 mi. 129.73 mph

Thanks Jody. This is the sort of information that actually means something. It takes some of the subjectivity out of the 'argument'.
If we can elicit enough information from enough owners, maybe we can see if there is a point of diminishing returns in the power/size vs. times.
Incidentally, I'm talking more about regularly driven (or regularly driveable) cars, not cars purpose built for dragging.

If you're talking about my car, it was not purpose built for dragging. It gets about 2000 street miles a year and goes to the track once a year. Take out the engine and you have a car like everyone else's here, I just happened to find the right combination that works well. This can be attested to by the many people that see it at the LCS and Woodward Dream Cruise every year.

That qualifies as "regularly driven"

Jack, the drag strip allows you to run almost 140mph with no cage!?

I have many pictures posted on my FB account....Jody Orsag.....check the following out:

The Gobra has over 28,000 miles on it in 5 years. It has traveled to California from San Francisco to San Diego down Hwy 1, and spent a week in So. Dakota touring the Black Hills and Sturgis areas. We have a trip planned from Salt Lake City, Utah to Santa Fe, New Mexico in the fall of next year. When we are not on road trips, we make the road course circuit, with a trip scheduled to COTA in February next year. The Gobra ran 167 mph on the transponder at Texas World Speedway the first time out in 2008. We have run and finished the 118 mile long Big Bend Open Road Race the past two years (with a a fourth place finish in our class in 2012) and plan to be back next year.

BTW, the valve covers have never been removed from the car.

So....the Gobra is not a drag car. We were at the drag strip on 4 occasions last year. It is well mannered, multi-talented, gets 15 mpg on the highway, runs on pump gas, does not buck and snort at 1,000 rpm in 6th gear, and is regularly driven by my wife.

I go to Norwalk now known as Summit Raceway. On Wednesday they let you run what you brung. That's the only way I can race. On Fridays they have a Test and Tune session, but it's strictly NHRA rules, because they run NHRA program on Saturday and a lot of the racers come on Friday for practice.
