Re: sled pulling gear

I pull in 2nd gear 4 low and usually place pretty good (3rd-5th place). I started off in 1st gear once by accident and then shifted to 2nd, but that didn't work out good at all, the engine bogged down and I lost my momentum. I haven't tried bbuntings idea yet, but I think I am doing pretty good in 2nd gear. What ever you do don't run in 1st gear, you definitely don't need that low of gear and you won't get enough speed.

Re: sled pulling gear

Having pulled a sled once or twice, I can tell you that whomever pulls it the fastest pulls the farthest (on a properly set up sled). MPH is everything-you want it to get into 3rd if the track is long enough.

Re: sled pulling gear

bbunting,

I agree with what your saying, speed is definitely a key factor, but in 3rd gear will a stock truck or slightly modded truck have enough power to keep the sled moving? Obviously your truck has more than enough power, but if you can remember when your truck was just slightly modded, did you have enough power? I would think the truck might start down shifting which could hurt your momentuem [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: sled pulling gear

Turn the chip to 120, get it moving, put foot to floor and let it go to 3rd. If you don't lay it all out you will be pissed konwing you could do better.

I don't think a slightly modded truck will pull 3rd gear all that well. Last year my truck was just standard bolt ons (AFE stgII, DP chip, Suncoast, exhaust) for most of the year. I had a pulling tune from Jody that was setup to shift 1st and 2nd and not go into 3rd. I had 35's which probably hurt me because when the pan came up it pulled it down real quick, but they also helped me get a decent MPH. A 33" tall tire in 2nd gear low at 3200 RPM should get you around 20 MPH. That's my 2 cents. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: sled pulling gear

I pulled in drive one time with my mild mods and as soon as the truck went into drive it totally bogged down and then downshifted. It did a ton better just pulling in second. I am sure there are lots of variables that effect this with power and gearing being biggies.

Re: sled pulling gear

Last time I pulled I put it in second and it hit the rev limiter very fast and I ended up pushing it into third but forgot to turn overdrive off. It ran through third then hit od and bogged. But I can keep the rpms right at about 3000 with the converter unlocked in third. second gear just isn't tall enough even with the 35,s and 373 gears with a locked converter it hit the rev limiter really fast.

Re: sled pulling gear

Has anybody ever done a boosted launch on the sled. I mean like giving the truck as much throttle as the brakes can hold back and then just letting off the brakes and matting it.
