Intentionally trying for a burnout is one thing, but the post sounded like he could just stomp it and fry the tires thru 3rd.

And you are wise to let out of it before 3rd and esp 4th. Your trans will be in pieces on the pavement;)

It aint mine, so I wasn't going to push it to hard. Just stomping it it would only do the chirping through 1st into 2nd. Still not bad for a mostly stock LLY on big meats.

If you can't fry the tires in 3rd with 500+ HP, you're not trying hard enough. :joker:

Before the build (525 HP / 980 ft-lb at the wheels) I would not only fry my 315/70R17 BFGoodrich's (12.5" x 35") into third, it would light them up from a roll in 3rd. :woott: Makes me worry about driveability once my new motor is together, as I'll be way past 500 HP.

But yeah, it is best not to fry them if you can help it. The problem is, like many on here, I can't go WOT below 50 MPH or so if I actually want to put power to the pavement.

You still have the stock turbo on your LB7? Both my brother and I have replaced our stock chargers, and it is night and day. You won't get the instant boost of a VVT, but the aftermarket chargers light quicker than stock. Though I still think a (mostly) stock LBZ is the ideal engine.

I imagine it is easier to tune the smoke out of a VVT than a fixed turbo. FYI, I've had pretty good luck getting rid of smoke and hitting boost quickly by turning rail pressure up until it starts to clatter, then crank the timing until you get most of the injection event BTDC. If the mild clatter (think 7.3 powerstroke) bothers you, a bit more pilot injection (or a bit less rail pressure) takes care of it.

Still a stock LB7 turbo. No money in the budget right now for a better turbo. Have a 2 year old that saving for has taken priority. And the wife's still mad at me for the carnage from my only time I took it to the track. I only twisted my driveshaft, but she wasn't happy about it. I've been bumping my rail pressure up a little here and and there to try and compensate for the added pulsewidth(basically trying to get teh same pressure as stock for a given PW). It runs pretty clean if I stomp it WOT and let it wind out, only smokes on spool and then it's clean. But on a 90+ day it hazes noticeably at half throttle. If it's 70 out, it barely puffs on spoolup.

Hmm....I could never do a burnout from a stop, not even with the big tune. Was more interested in top end. That logic seemed to work for me.
But in keeping with the theme of the thread, I could blow copious amounts of smoke. :hehe: Thats pretty much why I stopped running that tune on the street.

Oh hell no! :roflmao: A 'smoke tune' in a Northstar means blown head gaskets and a shitload of repair work. I do like my quiet, smooth ride, though. :)

Lope tunes are still cool to ford owners. The last guy that asked me for a smoke tune, when I told " it will smoke but not without power" ended up cracking a piston. So now I just

I don't know if my truck will do a burn out. I still have the planetaries with no teeth sitting and the garage floor to remind me.

Exactly! A lot of guys in here haven't experienced that and run their mouths about it.

And I don't think it has anything to do with a tie-up. All moving objects have inertia, what happens when the entire rotating mass of the driveline comes to an abrupt stop, cause your tires hooked up? All that energy has to go somewhere.

ah those bastards and their mouths.

yes, a tie up can very well occur during a burn out and be a contributing factor ;)

It's not the burning out that's bad. It's that abrupt gain of traction that feels like you got rear ended that messes shit up haha.
