When my car was bone stock it ran a 13.6.13.7 and with free mods high 13.5s.That's in 90 degrees and the humidity was somewhere around 90%. Now when I install LS6 intake,headers with ory and tune will I get to the 12.9s or lower? And how much more rwhp will I gain with these mods?

Its possible, I am running 12.74 on stock internals w/ Bolt-ons. I have a 78 FAST instead of a LS6, but one thing I have done is lighten the car some. Mods are Hooker LTs, into GMMG, 78mm FAST, p/p TB, Nitto DRs, and a good dyno tune by Frost, it gave me 330 to the wheels. I lied some on the internal, I did upgrade my push rods and springs, but that was mainly do to a planned cam swap, but ditched the cam at the last minute and left the springs and rods in due to having 120k on the car, figured it wouldn't hurt and helped strengthen the valve train, but that wouldn't gain any hp. Tranny and stall are stock as is rear, just added a cover for it, again no hp gain. So it is very possible.

Edit: I did also add pan hard bar and lower control arms and relocation brackets. That helps with launch and wheel hop which will factor in how the power shocks the tires and will get your 60ft down.

It sure as hell can, but i would say no. Whats your 60ft and trap speed with the free mods?

With and LS6 intake, Headers, and a tune on drag radials you're saying this guy can't get in the 12's????
With those mods you should be at around 350 rwhp.

That's almost a guarantee that he gets in the 12's if he's and average driver.

Why would you say no? I'm curious.

maybe if he can launch, drive, and run in decent DA

in the heat and 90% humidity...doubtful

My 60ft is 2.17 and my trap speed is 104mph.That's according to the last time I went in the summer time.

You are going to need a lot lower 60ft. Probably at least a 1.8x

It's amazing the difference a few degrees makes. In 40 degree weather my car runs high 12s with a lid and a cutout. Bump that up to 60 degrees and I'll be back running low 13s.

The mods you listed are more than enough to get any LS1 into the 12's. Focus more on lowering that 60' and your there.

I run 12.7xx with lt, lid, 3200 cirlceD convertor, swapped out the 2.73 for some 3.42.

This is what I thought, especially if its an Auto. Push the pedal down with some drag radials and your there.

Our cars make more than enough power to hit 12's as long as the suspensions/traction is dialed in.

Im not saying he cant but im saying he wont. The car has plenty of power and even more so now with the headers intake and tune but it is not getting off the line or something. I dont think an extra 40 horsepower will drop more then 5/10's off his 1/4 mile time being that all else is the same (tires, suspension, driver skill, DA ect...)

jthunderz28

I'm confused...It's an automatic, if he has "plenty" of power and drag radials how hard could it be??? Push the pedal down and go... LMAO!!

You'd be surprised what an extra 40 rwhp with drag radials can do vs. 40 rwhp on street tires.

Do you personally know the OP or are you just giving him a hard time???

Think about it, he ran 13.5 supposedley in 90 degree weather. If the weather right now in winter is more favorable with colder air, why would he not be able to run those times with more power.

It's possible. With those mods and street tires my friend ran 12.8 at 108

read my post again or if you dont understand it dont reply. You obviously dont understand what all else being the same or what DA means.

How do you know he has drag radials? Where are you pulling all this drag radial stuff from?

"Readers need to Read"

jthunderz28

That drag radial stuff is me saying he "WILL" do it with drag radials.
Not he "WON'T".

He never mentioned if he would be using drag radials or street tires. It's just insight man, that's all. You barely know as much as I do.

I do understand what you said, you just came off as a total douche. It seemed as if you felt liberated saying that he "won't". That's all.

Calm your self.

I dont give two ***** what he runs or not, must have just come across brash on the internet but that was not my intent. I was just saying all things being the same i dont think he will. With some more practice and better air maybe better tires i am sure he will.

jthunderz28

Understood. It just came off as very negative. You're right, things can be read the wrong way easily on the internet or just in the media period. Regardless you do have the right to your own opinion.

What tires are you running, OP? I would assume street tires with that 2.1 60'. The mods you listed on street tires are gonna be tough with the DA you're dealing with, but when are you planning on going? You said you went in the summer last time, so I imagine you can get a better DA down there this time of year.

My advice once you get the headers/tune on the car, start saving for tires and a converter. Even in a humid Florida DA, that should be plenty to get you your 12-second pass, although high DAs really are heartbreakers.

Good luck and keep us posted.
