well i made 5 motor passes today on 28x10.5x15S MT ET Drags. before on street 20" street tires and no weight reduction (about 4900 with me) i ran a best of 14.4@96 with 2.3 60 ft. Today i was pretty consistant, though it was not what i was expecting.i removed my sub/box spare tire and my nitrous bottle, which should be around 200lbs total. my 5 passes were:
14.60@90.1 2.09 60ft
14.58@93.3 2.14 60ft
14.53@93.6 2.14 60ft
14.49@93.7 2.11 60ft
14.52@93.8 2.13 60ft

I'm not sure what gears are in the rear since they are still stock, but i was barely shifting into 3rd at the 1/4 mark crossing at about 4300rpms i'm assuming i have 3.23 or 3.42's. and i cant 60ft for ****. Any suggestions on what gears would be better, without being too much for nitrous as well? Thanks

EDIT: its a GU5 which means i have 3.23's...

Here's a vid of the 14.53 run http://www.youtube.com/watch?v=T3hJqtX3z3I

 

i think u need a tune.. with all those mods. . you should be running low 13's .

 

it is tuned.....

he needs 4.10s to match his stall and tire size.

You have the MPH for mid-high 13s if you get that 60ft down

 

why are you running a 3600 stall?? that seems a little big for anything less than an MS3 IMO.

Also even with 3.23s you should be running quicker than 14s on slicks with nitrous???? something is definitely not right

 

what lift/lsa . . . . is ur cam?

 

I think his 14 second passes were not on spray

 

these runs were all motor. the cam is a 112lsa with 588 lift. the truck bogs a little on the launch even when i stall it up to 2800 rpms. im going to see what it does on n2o tomorrow

 

i would go with 4.56 gears are 4.30 it wuld be a nice set up and you would get some low 1.60 60' are 1.5 60'

 

+ 1 on the 4:56's. You will like them with your set up. You would be deep into third gear at the 1/4 mile and still pulling hard.

 

I have the same mph....no way my truck is mid to high 13s lol
