Nice runs! What is your 1/8 mile times?

XTrooper

Excellent times!

Next time at the drag strip, lower the air pressure in your DRs to 16-18 psi. Your 60' times and, consequently, your 1/4 ETs should improve.

RGR Pete

Thanks X-trooper, The last run was at 20psi. I don't know these tires and I did remember from years ago that the big end boogy ain't my kind of dance.

Man, I am digging that!

I hear ya, but as they are radials, you shouldn't experience this like you would with bias-ply tires. I routinely lower the air pressure in my Nitto DRs to 16-17 psi and I get no movement whatsoever even with 114-116 mph trap speeds.

RGR Pete

1/8th- 7.81 @ 89.1
Xtrooper- Don't radials start to cup at lower pressure?

I see you have a tune on the car . Do you happen to know what rwhp you are at ?

XTrooper

I don't know about that. All I can tell you is that I'm cutting consistent low 1.7x 60' times with my Nitto DRs set at 16-18 psi and my light-hitting Yank SY3500/1.63 torque converter. Others are cutting 1.50s and 1.60s with their M/T drag radials, something you'll never manage at 20 psi.

I suggest you try a lower pressure and see what happens!

P.S.- Take a gander at this thread if you haven't already.

Sweet! It looks like I am right on mph wise, I am hitting the 1/4 for the first time with this set up on Saturday. (I ran 7.96 @ 89.21 in bad air)

I ran my old 245-50-16 Nittos @ 16psi, no wobble at the top end.
