Ok... I am sure that these kind of posts get old, but I am a new LS1 owner(former mustang owner) and I am curious what you guys think my car would run. Here is a list of what is done to the car, it runs very strong and I easily pulled on my buddy who has a brand new 2010 Mustang GT the other night.
Also if anyone has any ideas what I could do next to gain some more power please let me know. I think my next mod will be ls6 intake, if I bolt on ls6 intake will I need a new tune?

Nobody has any input, I did not see the drag racing section until after I posted. Maybe I posted in the wrong section. Sorry if i did

Welcome aboard. Your setup looks pretty darn good. The LS6 intake will help you out for sure. You will need some tuning to since the LS6 intake doesn't have EGR. So you'll have to have that deleted from the computer. Also there might be some additional minor tweaks to the spark and fuel to get most out of the intake swap.

2002 Z28 A4 NBM- Sadly now demodded :(
Slap some Mickey Thompson ET Street Drag Radials on that and it'll turn mid-12's for sure, probably faster. I have less done (no engine mods and not lowered) and turn mid 12's. I have roughly the same TC, tranny mods and gears + MTI lid with QTP SS LT's, no cats, X-pipe with TD's and Magnaflow's dumped at the axle. Best run to date is 12.59/108 with a 1.73 60'.
You should invest in an LS6 intake manifold. The LS1 intake is limiting the upper RPM potential of your cam. Being lowered you may need relocation brackets for the lower control arms. I'd also be thinking about an adjustable torque arm, preferrably a body mount type.
Like I said 12's for sure.

What kind of dyno were those number from? Dynojet or Mustang dyno? Curious about how much power you car really has since both dyno's read different from what I'm told.
Definately get the LS6 intake. For all the mods that car has done the LS6 should have been done along time ago. Get some better tires like a set of drag radials for the back and you should hit mid 12's to low 12's depending on the track conditions. I've seen 11 sec cars run 12's because the none of the cars were hooking up.1998 Trans Am 85k miles.

That cam is not a big one and dyno numbers are just a tuning tool. Different dynos read different numbers, who knows on another dyno it might put down 370-400whp. I would say with the tires you have mid 12s are possible, you get some drag radials and that car dialed in and 11s are in your sights.
2010 stock mustang gt would get rick rolled by this car. It would have lost to you stock most likely.

You can compare against my mods... I run 12.5's consistently, but have some trouble keeping the tires planted.

I would definately go for the LS6 intake and a new tune. I have a pretty aggresive tune on my car, I deleted the dyno tune that I had done since it was running way to rick and we plugged in a portable wideband 02 and started tuning and driving till it was running pretty near max potential for my mods. I could probably add a little more timing but it wouldn't be worth it. My car drives great gets 250 to 325 a tank depending on how hard I'm pushing it.
