I'm runing 2.5 60' times with drag radials but my 1/4 mile is 13.8@109. I'm preloading the tranny and going at 4800RPM. anyone have any tips on how to lower my 60' times?

I was cutting 2.3's on shitty *** street tires and only getting 15.5 @ 90. You need to launch lower. I launched at around 2000 rpm and lsipping the clutch.

 

What kind of tire pressure and what brand/size radial?

 

You need to lower the tire pressure most likely, do a good burnout. And If your not spinning launch higher.

for me i would do a second gear burnout.
launch at 7,000 on the 2step
cut 2.0 60'

try lowering the pressure to like 12.. it might help

 

i ran a 14.2 . with 2.0 60 ft.

i was on toyo proxes t1r.

 

dont be scared to drop them down to like 7-8, with a decent burnout, you mph is crazy high for that time,

110mph should be good for at least a mid 12

 

i'm goin gto try that. I'm going to start at 12 and work my way down

 

best advice, learn to drive.

 

trying too

 

try launching at like 3k

and dont give it all the gas sorta ease into it,
there is no excuse for a 2.5, seat time and getting used to the car is what u need

 

im just being the obvious dick. you need to tell us whats happening. we cant just sit there see your 60' time and guess whats going on in the car when you launching it. more info is needed.
when i had DRs all motor id launch at 5.5-6k and just dump the clutch. ran 2.0 60s in my 2500lb coupe with B18c1, ITR cams, 3" short ram, ITR ECU, DC 4-2-1 header and exhuast.
ran 1.9s on those same DRs in my light *** hatch when it was a street car with more done to the motor.

 

yeah im with fmfkid on this one im finally getting some decent launches 2.0 pretty consistant still 2.0 arent really that great i would like to see some 1.8xxx but yeah i usually dump it around 4k or so and ease into the throttle a little bit then when i feel it strat to catch i nail it and ive been getting better almost every time it just takes about 10-15 passes or so to start running consistent good times

 

I launch @5k rev to 5 and dump it and pull 1.9 on DR, works for me
