I need slicks or need to learn to launch.

[Fat Tony]

When I take off and floor it, I go sideways.

When I ease it, then get to full throttle, I spin.

When I take it to 7lbs of boost then let her go, I can spin for blocks.

I've checked most of the junk yards, I'm trying to find a set of wheels (with tires) for Thursday Nights (1/8th mile) and can't find anything cheap.

What is the bolt pattern on my 2006 F250? What is the oldest Ford rims that will fit.

I'm willing to go to 15" wheels is necessary. I can always find a bald set 33's someplace in L.A. If bald 33's aren't the way to go, what is?

I know I can run 9.3s or even less if I can launch at 7lbs of boost and don't spin (4x2).

Any advice? I even got think I can do a 9 flat if I launch it right.

I'm assuming your 2wd...

You need to work on your throttle control. Launch at a lower rpm/boost level. Also, look into putting some weight into the bed. Chain 4-5 cinderblocks together as far back toward the tailgate as you can. Since your 2wd, you'll have to work on your wheel spin. Start from just easing onto the throttle, then build 1-2 psi at a time or try ramping up in 200-300 rpm increments. You have to find the sweet spot.

as for the wheels the 15" will not work on your truck due to the fact the calibers are to big and the bolt pattern is a 8-170mm and ford has been using that botl pattern since 98 on the F-250 and all SRW F-350 and the DRW F-350 have a 8-200mm bolt pattern..another idea for the traction controll is about a 1/2 hour before the event take some bleach and soak your drive tires that will make them softer and glab a little better..hope this helps..

You should think about a Detroit Locker..... It will Bite Harder..
PS: those are 1/8th mile times RIGHT ????

Only the 05 and newer DRW 350's have the 8 on 200 bolt pattern.

FAT TONY. I know exactly what your talking about. I was at my local 1/8th mile track Thursday night and have the same setup as you and I can launch my truck at 1200 RPM and not spin but at 1200 RPM that is not a very good launch, but if I spool up to 1500 RPM I spin till I let off the pedal. I to am in the market for some slicks. The best time I have gotten is a 9.38 @ 76 MPH. I have watched 4 wheel drive trucks take as much as a half a second off their time when launching in 4wd versus 2wd, that would put me donw into a high 8 and I'd be happy with that.

You can do the bleach trick, maybe lower your air pressure a bit, you will have to play with it til you get the result you want.

[SgtStroked7.3]

yeah, i would try to add weight to the back, cinder blocks or sand bags... and if that dont help, Wal-Mart always has cheap tires...lol

[LTJDS]

Detroit Locker in rear diff and if you need it there is a bag they sell that lays in your bed and you fill it with water,,just over 8#'s per gallon times at least 50 gallons ......thats a 400lb minimum. Check my garage and look at my old 2002 F350 7.3L SRW 2x4.........GET A LOCKER 4 POSI Take off
OEM limited slip is a JOKE.....Good Luck

Shur-trac I think is the name of the bag your talking about John. I would have to look it up on our server to be sure. Not sure what price is either, but they are pretty cheap I'm sure.
