Racing?

[tmg115]

ok i know this will sound dumb but would it be better to race in tow/haul mode?

[mackin]

My opinion would be No........For the reason of in tow haul it will hang in gear longer......I'd rather it shift to a higher gear ratio ...With the amount of torque I got it runs real good in higher gears......Pulls strong......Even in OD...Once your in the power band only a higher ratio will get you going at a quicker ground speed .For faster ET'S.......
MAC :D :D

Who in hell would ever think of racing a 7500 # truck anyway.... ;) ;)

Mine runs faster in tow haul mode, confirmed it on the race track.
OH, mine only weighs 6200#, 15.46 at 88.7 mph in only 1320 feet from a standing start.
(this is minus driver, he weighs 220)

Buick Gran nationals to keep up with ya !!!

[mackin]

PEANUT,

Are you running propane and Bd at the same time? No limp?How does tow haul give better et's? When it's designed to give EXTENDED shift times.........Please explain.
MAC :D :D

Sorry, been at the race track last 2 days, mine has an Amsoil filter and a Dynomite box or Van something or other with 30 or 80 hp setting and P265 R75 Coopers.

I recall Tow/Haul mode locks the torque converter for gears 2,3,4, and also 5th (IIRC). Of course less gear slipping means better elapsed time. ;)

[PEANUTGRWR]

MACKIN, AZKEVIN SAID IT------ LESS SLIP BETTER ET JUST TRY IT YOURSELF USE A GTECH OR TAKE IT TO THE TRACK. YES IM USING PROPANE WITH VARIOUS OTHER MODS!!!!!!! :cool: NO CODES RACING BUT HAULING IS A DIFFERENT STORY

[ford2chevy]

I agree, in Tow/haul the converter is locked 2nd-5th--has to be quicker.

[madmax7]

Could the better times in tow/haul be a result of improper or different tranny training methods?

[Joe.G]

No, it just shifts harder, I believe it also raises the line pressure to the clutches to get a firmer shift. The tourque converter being locked will increase the harshness of the gear change, in other words you don't get a smooth gear change, it shifts hard!
I almost forgot, T/H mode made about 2 1/2 tenths difference in 1/4 mile ET.
