Yeah, if the DA was 6000. My bolt on car making 368 rwhp trapped 113 and ran 12.4.

I am launching around 2800 rpm. I used to drag my cobalt SS quite often so I am familiar with the track. My cobalt would trap speeds of 115 plus and spinning down the track.

DA can't be that bad with a track eleveation of 400 and temps of 75 degrees.

dekan513 · 07-07-2013, 03:24 PM

i didnt know if he knew or not i know some one track says 1900 elevation in his state. but most are around 500 range. but if he is only making 490 at the wheels and da up around 2500 to 3000 just guessing that could account for alot of it. just tryin to help him figure it out. i know my car weighs less thing his and making around the same power now i usally trap around 117 average. n/a

I would say something off i ran 12.50 all day on a bad day back when i only had a little LS hot cam header & 3200stall

2ssx2 · 07-07-2013, 05:35 PM

I agree something is way off. I would say 12.50 should of been a starting point for only running the car 2 times. I would think this car able to run 12.0 pretty easy

I ran the corrected da numbers for the track yesterday and they were within 2 tenths. So basically a perfect day. Wish i could figure this out. I will take to a dyno this week and have it looked at.

Good idea, this way you will know how much power you are putting down. Your dyno will shed some light on a possible issue.

Btw, Terry's bone stock 2013 Auto went 12.7x with no mods.
Your time is off for your mods.

Not sure if he's convenient to you, but Ellis is a long time friend and knows his way around quick LS cars:

Thanks for the info.
I did a fuse pull and some data logging. Still getting some knock retard around shift points and when I first get on it. 4 is the worst I seen but I would rather have none

2010SSRSM6 · 07-11-2013, 05:53 AM

Where you have the E-Brock did you get the upgraded fuel rail? It starves fuel from #7 if you didn't. That could explain the knock.

What tires, pressure etc. we're you using?

Remote tuned? What's the altitude of your track?

Slickcas · 07-23-2013, 01:23 AM

Get to a Dyno. They will hook up a wide band O2 and look at run. I bet you something is off in the tune. That thing will be a tire shredding monster. If you ever add any boost to that E-Force the JRE fuel rail upgrade is a must. I know JRE tuned it and he is VERY good . But even god makes mistakes sometimes he let Ford build the mustang II.
