I still think i could have left a little harder on that last run, and the weather was probably somewhere near 60* so the car's still got more in it, and the next time ill be at atco, hopefully improving to a 12.70 or better.

Very nice runs.:thumb:

Nice, escpecially with a vert. You need to work on leaving a little more and you can run 12.50's with 106mph. Do you have the front swaybar on? Also try dropping the pressure on those tires. I find they work good at 15-16psi. Later Clint

let me hear more details on ur setup..like clutch? roller rockers?..how many miles on the motor.. 4:10 10 bolt? what were u shifting at?

We have identical mods pretty much and im shootin for very similar times..
back in June i went 13.4@104 1.9 60' in like 85 degree weather at Atco w/ 141k on the motor..
im goin to Maple Grove nov 4th to shoot for a new best..i wanna leave the line like you but i fear of the 10 bolt on this BFG drag radials

sorry all i was sort of drunk last night when i posted that...full mod list was as follows:

k&n cai w/ no filter
!swaybar, !a/c, !emissions
longtubes to a borla with no cats
b&m ripper shifter
spohn tubular lcas
bmr subframe connectors
ram or zoom clutch(MINOR upgrade from stock)
~50kish miles on the motor(i blew mine up and bought a stocker to throw in there)...motor is bone stock from tb to pan
4.10s in a stock rebuilt 10-bolt with a girdle

u notice big difference with !swaybar thou? 1.8 60's are nice

I dont honostly remember how the car was with the swaybar...its been off for at least a year now

Thats very good! I'm still in the 13.50s with similar mods, but I'm an automatic and the DA was in the lower 2000s. Maybe I can get closer to what you're running in decent weather. Very nice!

very nice runs. you didn't say what you shift at
