What does it take to run 12's?

Sorry if this has been posted numerous times but I have been searching and couldn't find anything on this.

I have an 08 4x4 4 door. Just did the H&S mini, dpf delete, and S&B CAI. What else is needed to run 12's or would I need fuel and turbo upgrades. Not interested in running nitrous. Also what are my current mods good for at the track? Thanks for the help

I ran 12's with just an intake, exhaust, and the Spartan 310 tune. That was on 35's and a leveling kit. I have since gone 12.4 with the Spartan 310 on fuel and with minor upgrades.

1. SunCoast transmission and torque converter (and Spartan TCM)
2. EGR cooler delete and CFM+ intake elbow
3. Elite ported fuel rails
4. Air Dog II DF-165 (not needed)
5. CalTracs traction bars
6. Toyo Proxes
7. Big weight reduction (got my CC/SB down to around 7700-7800 lbs with me in it)

Thanks for the info. So I should have no issues running some 12.9's low 13's in good weather on a 260hp tune correct?

Yep, you should be high 12 to low 13s with a good launch and a decent track.

Let us know how it goes!

I can't speak for others, but I put the truck in 4-hi get the boost to 12 PSI and let her rip. Anything above 12 and I start to overpower the brakes. I am planning on hitting the track with the new 300 tune and see what it can do.

I can launch at 20-22 psi, but the sweet spot for me seems to be 16-18 psi. Anything above 18 and the front starts hopping.

Ok so just to make sure I have this right. Put the truck in 4hi and leave it there throught the run..?? I assume that is right but just wanna make sure.

Also as far as brake boosting goes. With a few of the Lightnings that had turbos on them we would use the e-brake and rig a little wire to the release handle. Worked great to help build boost since they did not make a transbrake for the 4R100.

I put mine in 4 hi and lock the hubs. Once I am through the traps, I turn the electronic 4wd off. I leave the hubs locked the entire time I am at the track.

Not sure on the break boosting. I just hold the break, build boost, and release when the tree drops.
