2001 automatic SS with nitto 555R dr, cai, full exhaust and lt headers, slp lid, new autolite plugs, a custom tune, subframe connectors, and a strut tower brace making 316rwhp and 341 rwtq. went to the track sunday made 5 passes first time with this car at the track. My best time 13.31 at 107 mph 60' was 2.3 does this sound about right

 

your only making 316 rwhp? umm 13 seconds maybe better if you can really drive

 

with those mods i would say like a 12.8, but the 316 horepower makes me think more like 13.2 at best

 

Why do you guys put so much stock in his dyno numbers? I know it's thing we have to go off of, but I have seen dynos be off by 10+- rwhp before due to several factors. Being that he has a drag radial there is no reason he can't run a 12.8 or better. I ran a 12.5 @ 110 mph with less mods.

 

Im sure with practice i can get better my goal was to hit a 13.0x or better yet 12.99 just so i can say i hit 12s but i dont know if i can make it or not and my 60' foot time is slow my best was a 2.3x

 

I tend to agree with JD. The dyno is really a tuning tool. People tend to look at peak power, but it is the average power/torque through the RPM range that makes the car move. Also, a lot depends on the driver, especially the 60' time. Practice and good technique makes a big difference. Also, different dynos give different results, usually Dynojets show more power than Mustang Dynos, and power readings change with atmospheric changes,but it really makes no difference because you don't win races on the dyno.

 

Hey guys I went back to the track today and made like 3 or 4 passes . I improved from last weekend having a best time of 13.31, this was my first time and today was my second. Heres my new times

R/T .596
60' 2.107
330' 5.593
1/8 8.459
MPH 86.11
1000' 10.949
1/4 13.067
MPH 106.59

 

Whaty pressure are you running on the drag radials. I always let a bit of air out of mine at the track. Runs best with them at about 18 - 20 lbs. Why not take 2 lbs out and try it (take it slowly, a small step like this at a time -- reducing pressure changes the handling and you don't want to go too low for your car and tires).

 

ill try letting out a few pounds next week when i race i had 30lbs in it yesterday when i ran

 

You have the mph for a solid 12 second run, just get your 60 foot down. I run about 22-24 pounds in my BFG's, if you are on a 275/40/17 (stock size for your car) be carefull going less than 18 lbs orso, the tire will cup and you will spin more.
