I have been rummaging through the power adder threads with (Everyone is using that, so I suppose I ought to as well - though in a different context.)

There are few members that have ten second cars to begin with, and the search function is not the most efficient means to search for these folks. Usually, I am very loath to inquire publicly about items of concern as such because they are, in a way, abnoxiously general. However, seeing as I have done a weeks worth of search with meager results, I am certainly not as anxious about this:

Assuming a suitable and appropriate drivetrain is in course, consisting of a TH-400 or 700r4, and Currie 9 inch rear-end, what is a necessary amount of peak horsepower to in deed make quarter-mile runs of 10.xx. I am assuming the car weighs no more than 2 tons with the driver. This would be done with a 383 and procharger D-1SC.

 

There is a big difference between a car that weighs 3400 pounds running in the 10's and a 4000 pound car running in the 10's. 600-650 horsepower is a good start assuming everything else is up to par.

 

I would assume so. However, things are being built to support more than 650 horsepower, making power changes as simple as a different pulley and retuning. I would assume that keeping it within 7xx horsepower will bring me my goal. Now I am wondering what is too much for street/strip.

 

I didnt think there was a such thing as too much

 

When I can't afford to pay the gas bill for a run it's too much. I wonder how much it costs to get a Top-Fuel car from one end to the other.

 

I'd agree that between 600-650hp is a good start, more if the drivetrain/suspension is not working properly or not matched to the powerband - less if you set the car up to 60ft and 1/8mile really well(ala super stock and stock eliminator cars that run well into the 10's at under 120mph).

HTH,
Steve

 

Basically you need a weight(Lbs)/power(BHP) ratio of 5.86 to run a 10.5, assuming that the car is optimally geared and things are fairly optimized. Figure out your weight and you can get your HP.
