No offense. But i think your wasting your time. I no you want more power but you need some suspension work or swap that thing to a auto. I understand you only go once or twice a year but somthing is wrong. What do you have for lower control arms and torque arm?

My buddy had a procharged camaro six speed wi

Stock lowers and torque arm. Car is lowered and I don't have the Relocation brackets. Plan on a 12bolt with BMR torque arm, control arms and relocation brackets this winter. Might have to do more suspension stuff before the next trip to the track. Gonna go ahead and order the head studs and get this build going.

Something is not right. My 98 Dakota with a whopping 230hp @ the crank will get mid 15's in the quarter.

Do you have a shift light?

Could be elevation mine did a 13.8 at 4-5 psi .....granted with horrible tires and slow start to prevent spinning but my mph were higher then that. 5.0s do 14s over here too lol

The only reason im questionin is my buddys car with the same power would go super low 12z high 11s on street tires. Bone stock suspenison.

I was a 12.2 spinning with a bad 60 foot on a cam bolt on car making 393. it was prob high 11's. I am now procharged but have no runs on boost yet.

however..... if that car is on 10lbs....something is up. it should be in the mid to high 11's

Id ditch the zr1's and get a stock 17'' wheel. ditch the nt555r and get either a nt05r or a MT

its also a 6 speed.


it sounds like a mix between the suspension not handling that power and possibly need to make some shifting adjustments.

this guy right here has it down pat.

This is only on 8lbs, and he is at 121mph.

What you should say, is, the hp isn't the only problem.


I don't care what your car made on the dyno, because it's obviously not reflecting in the mph. Did the tuner give you a good dyno# then richen AF and back off timing to keep it safe? Is it pulling timing during the runs? Hard to say without a log, but bwkmaro is right as a time slip would be nice.

get slicks, until you do suspension research that will help you hook on a radial. get a 2 step. leave on bboost. bang gears like a mad man or go auto. 1200hp wouldnt help you at this point.

Well I don't know what the timing is at, I bought the car this way. Stock LS1 with a F1a procharger. I have a video and slip that I will post tomorrow. Hopefully I find out that it's my driving skills. First time I went to the track I was seeing about 6 psi. I ran two 12.70. One at 110 mph and the second at 116. I have a old oil filter i am
going to cut up and see if I find any metal. Thanks for all the suggestions.

Here's what you need to do.

-Used set of LCAs off this site
-Used set of 15x8 Weld or Racestar wheels
-275/60/15 MT DRs
-Remove front sway bar
-Used torque arm off this site

Then.... Have fun with 11's.

Something has to be wrong. At 10psi on a stock LS3, no headers, stock heads, stock cam, I ran 10.5@136mph. My race weight was 3500 pounds, full street trim. I've seen fbodys go just slightly slower at around 130mph with supporting mods. Autos might ET better, but something is wrong.

The numbers from these posts aren't matching. Honestly you're not taking anyone's advice if the only thing you are doing to trace this problem is cutting up your filter. I have no idea why you don't want to listen to ppl trying to help you, but whatever. Good luck.

agreed on it being no problem, or shouldn't be. 487rwhp/440 tq n/a last year got me the numbers in my sig....10.37 @ 128 and a 1.37 short time with a 4l60, 3600 stall & 3.70 gear @ 3400rw. something is wrong and it's more than just your short time. post a vid if you can and maybe that will reveal more of the big picture.
