Competition 1/4 mi. times at various hp.

[RMalone]

What are the ballpark figures?? For instance, what kind of 1/4 mi. times would a 450hp truck get or 500;600;etc?? I realize many other variables exist, driver most notably, but lets hear it.

My truck with 400 ran high 14's with the G-tech pro. I would think that an auto with 450 and enough turbo would be knocking on 13's with 4WD launch and torque converter lock up switch.

HP #s will get you closer to mph #s et's will vary more at the same HP,weight all being the same

I ran a 13. 7 at 104 mph this past fall. i launched at 10 lbs of boost. RWHP is 562 with 1129 ft/lbs. I think with the RASP program i could get a better time with a harsher launch.

I also made a run of 14 flat at 94 mph - i had the OD turned off

I ran 13. 9 @97mph in 2wd this past fall. The truck is STRONGER now. :-laf

I haven't done a quarter mile since the twins were installed, I imagine I should be quite a bit faster. The 14 second run was with comp box on level 3, EGT's were too high with the stock hair dryer.

EGT's were too high with the stock hair dryer.

oh yeah, even with the HTBG I was hitting 1600* on the top end. I will be going bigger just haven't decided HOW big. :-laf

15. 8 with 380HP at the wheels.



Oh ya, the 6 speed is sloooow#@$%!

 

[SRadke]

I'm curious about 6 speed times. I've got fair power but rowing the dual disk has gotta be a hinderance.

On Feb 16th we ran a 13. 7 @99mph w/6spd trans (manual) I believe the truck to be just under 600hp.

 

[DCreed]

are the six speed guys skipping like 2-4-6 shifting or going through all the gears?

 

[KLockliear]

WEIGHT is a big factor.



530rwhp, 6900#, 4-hi launches at 15psi, DTT 93% converter = 8. 5 in the 1/8 at 82mph, 13. 39@104 in the 1/4



Same truck, 740rwhp = 7. 4@86 in the 1/8, 11. 96@111 in the 1/4

I launch in 3rd, and then go through the rest of the gears. I shift into 6th about 60' before the line. Some guys skip 5th just go from 4th to 6th, but I have not tried that yet.
