One of our GTO forum members caught the run on VIDEO...would've looked alot quicker beating one of the GTOs instead of running a 10 sec GN! lol

 

holy ****, nice run!

 

man i would lose any day to run a 12.98 in a truck that size

good run nice truck

 

Nice run! Not bad for a Yukon!

 

Not bad for any ride!
Damn Colby you'll be passing me real soon!

 

Nice run! What do you do for traction....what tires are you running to hook in 2wd?

 

I was previously running Goodyear Fortera HLs in a 285/50R20 and had really good traction with those. I ran consistent 13.70-80 and 1.93 60s before adding the AFR 225s and meth. I just put on a brand new set of General UHPs in 275/45R20, and with less than 500 miles hooked the 1.91 above. This was the first time getting on it (street or track) and didn't know where I'd lose traction, so I didn't push it as hard as I could've...felt like I could've been heavier on the pedal without spinning.

As for launch style, I've tried both progressive pedal and stabbing...stabbing put me at 2.20-30 with spinning so I stuck with a fast progressive pedal from a 2500 rpm brake stand. Seems to be working well and I'll keep experimenting with that til I find the traction loss.

 

Thanks guys!

Bill, I sincerely doubt that I'll be getting where you are without drag radials. Although, a 50-shot has been suggested by friends...just to give a little more top end. ;^)

 

Were only a few tenths different now, amazing since the last time I saw you run you were mid 13's.
I wouldn't think that heads would make such a HUGE difference in a S/C setup, hmm....How many lbs boost you making?

 

I think its more the AlkyControl allowing more timing with the boost. My boost drops off significantly after 3700 and we're thinking the oem TB is restricting the flow...want to get the WCCH 90mm j-tube (when $$ is there).
