I remember reading about some guy taking a Hummer H2 to the drag strip. R/T was so off because rollout on the big tires.
After a few runs he was able to figure out when to take off and R/T was driving others nuts that they didn't get a red.
Found the article... good read on R/T and rollout.
The Last Amateurs - Hummer H2
It is really weird racing the Raptor with a 35" tire vs. my drag truck with a 28" skinny up front. Roll out is totally different. Really throws me off at NMRA because it's a pro tree, whereas my drag truck I normally race with a normal tree and shallow stage it for the best E/T. So shallow staging on a 28" skinny vs. deep staging on a 35" behemoth, it feels like I'm rolling into the beams foreverrrrr when I try to deep stage the Raptor vs. what I'm used to LOL!
A 2.1 60Ft isn't bad but i was expecting better. For the launch, traction was never a problem. I had the truck on 4A and pressed the brake and accelerator at the same time and brought the revs to about 3RPMs and launched. My GTR would rev to 5k RPM at launch. Maybe a tuner can fix that.
I do see 13's stock regardless with just better Density Altitude. 13.5 on some of the east coast tracks that get negative 2000 Density Altitude.
12's with full bolt ons will be no problem! You will hurt alot of feelings

Yeah he beat me because of my slower reaction time even through i was closer to my dial in

Thanks i always like to get a baseline before modding to see the differences
Next time around try 2wd. Not sure if it was still launching in 4 with it in 4A, or how the auto mode splits the power, but the less losses you can have the better, so if the track is sticky, our trucks are so heavy and now ridiculous power, that 2wd will usually still hook fine, and should be quicker than 4 if you can get 2 to hook. I'd drop mine to 40 PSI and it wouldn't even chirp the tires (which cracks me up because normally I'd run my skinnies at 40psi and my slicks at 19 lol).
Also play around with launch RPM. Even though it's a turbo 6 like the GTR I have a feeling it will like a drastically different launch technique. Especially with how much gobs of torque the truck makes down low, and with the 10 speeds, a lower RPM launch may actually make a decent drop.
With the Gen 2 Lightnings (I know drastically different power plant s/c v8 vs tt v6, but they also made gobs of torque down low), on a stock converter launching them at idle actually yields the best 60' time. Kind of counter intuitive for a lot of folks that think high RPM = hard launch. Sometimes flashing the converter is like kicking the truck in the *** out of the hole. Now turbo will need some RPM to help spool so I don't think idle will be the ticket for the gen 2's, but who knows. All I'm saying is it'd be really interesting to get some data to compare....1k RPM, 1.5k RPM, 2k RPM, 2.5k RPM, etc. and see what takes the cake.
Does anyone know what the old Raptor run?
See my last post, I know it's long but it's detailed in info. Gen 1's were pretty consistent around 15.2-15.4 bone stock. 14.8-15.0 with an intake & tune.
