video of sled pull.. imptovement opinions?

[L0B6Z]

I know I'm running low rail pressure and gotten 22lbs of boost, but how can I keep my truck from lifting so much? I lowered it and added 1ton springs.

so any input would be great.. I get low rail above 3800rpms, I'm spinning 4200ish down the track at 20k rail.. Didn't do this till I ported my fitting. Stock fitting is going back in. Buy I want a gd setup and to stop blowing my tires off. I'm running 20lbs in front tires and 30lbs in rear. Truck is sideways down the track

Get your hitch as close to the back of the truck as rules will allow. It gives less leverage to the sled to lift the front of your truck. Here is a picture of mine.

hitch is custom and tucked in alot.. 5" past rill pan..

 

[L0B6Z]

yeah mine is just like yours... Love the lol.of it

 

[Micheal Tomac]

you need more rear tire pressure, you're losing hitch height with only 30psi in the rear

you also need adjustable stops in the rear

does it always dog track when you pull?

 

[L0B6Z]

I'll try more air in the rear tires.. When I'm at 45 I smoke the tires. We are not alot bump stops aswell.. My friends 07lmm barely sags and lifts only about a inch..

 

[LbzDMax07]

Can or do you run airbags to help with the drop?

 

[L0B6Z]

no I wish. Not allowed airbags... I might sneak in bump stops and I'll raise my front with a shim of some sort

Obvious question is,is his set up any different hitch ,truck model,etc etc , including brand of tire ?

you want to lower you torsen bars down all the way if you're not hanging weight

and don't cheat, good grief. If it says no bump stops, then don't run them. Pretty simple concept. :thumb:

all stock even tires. Not aggressive. Stock trans tune, no sleeves etc.

I don't have my torsion bolts in right now. Lowered the truck so I didn't have to keep messing with them.

side note- should I crank up the bars any for when I do run wieghts? Will run them next yr where is allowable

well most places don't let you. I ran em once and I hopped bad. I think I'm gonna have them set to 1" of travel and try it. I hopped when it was blocked completley.

I am also going to order the arsenal kit for my cp3 so I can keep fueling past 3600rpm.

working on a set of front end stops to keep my front end sitting where it does while pulling down the track.(bolts all the way out). I heard this helps keep hitch hieght.

also got some wieghts finally. Airing fronts down to 20lbs and rear to 40lbs. Going.to try lockup box also

Nick, don't waste your $ on an arsenal kit...just my 2 cents....

Are you not adding any weight right now? If not, that could be a big part of getting traction also.
