Just curious what kind of power it would take for a 3700 lb car to run 11s.

By looking it up you will need about 430 to put you in the high 11's.

 

i don't really find that true. i've seen guys laying down 350rwhp and pulling 12.10's and such on ET streets, 3.42's and 2800-3200 stalls. it's all about what you can out of the hole. i've also seen guys run mid 13's trapping 113 with 2.2 60's and spinning through suspension. a full suspension would have you flirting with 11's on anything 350 rwhp +

 

Yeah there's a lot more variables too a good track time than power. You can drop half a second or more sometimes just by getting some tires.

 

Took me 431.6rwhp to get the 11.46

 

The reason I asked this question is because I just recently dynoed my car and only pulled 339 rwhp. I thought this was kind of low for the times my car has run at 3700 lbs.

 

Also depends on the dyno.

Dyno's are great tuning tools and can give an ideal of how the vehicle might run.

But they are no end all of answers because how they actually run might surprise you.

Take my Lightning...now who would think that around 430 rwhp in a 4700 lb. truck with crappy aerodynamics would pull down almost 113 mph in the 1/4?

 

It took me 400, er 362, er eh 385 rwhp to run 11.51s at 118...I don't know what the hell it takes to go 11s...I thought I did...mmmmm...

big dave i sent you a email.

 

I didn't get it.

 

big dave i was wondering what dyno you made 339hp on mustang or dynojet?

 

I dynoed 369 hp and 417 tq on a dynojet and ran the times in the sig and my raceweight is 3400+.

It was a mustang dyno

 

If you have a built up automatic with a stall, with some good tires, you won't need more than 350 rwhp. If you are like me and have a 6-speed and aren't the best at racing on the track, (even with the best suspension money can buy) it took me 425 to get to the 11's. (yeah... need to work on launching at the track.) Sometimes with the right driver and suspension set up on the car it may take much less.

 

i dynoed 319 and went 11.96@112.60 with a 1.67 60ft. tonight. 3540lbs.
