Saturday, I participated in a WannaGOFAST half-mile event here in north Georgia. It was an awesome experience and I received ALOT of attention with the truck. The staging lane is a single file half-mile long string of cars that runs right through all the spectators... so it is essentially a rolling car show. Very cool feeling when people come up to me and are excited as I am of my last pass and want to know more about the truck. I even had people walk up and ask to put cameras on my truck... it is just a great feeling to see so many people who appreciate my vehicle almost as much as I do. I was filling up my fuel cell for my trip home about 11:30 at night and some guy stopped by to commend me on my runs that day, so it seems I made quite the impression.

I put up shop with Injected Engineering who had some amazing cars there as well. They have a Hellcat that make 780 or something rwhp, ran 150s IIRC, a procharged SRT8 jeep that ran back to back to back 155mph passes, a roush mustang that ran 165 as of saturday. They probably ran faster on Sunday but I wasn't there to see. Some really great people in that shop and I'm blessed to be friends with them.

I made my first pass on my street tune (19psi, 14deg) and I ran 142mph. It isn't a race-prepped track so hooking up in 1st was not very smooth, but it pulled hard all the way through. I didn't get a video of it, but some may pop up on youtube at some point. Put a bus length on a corvette and then he let out of it about the 1/4 mile marker so not sure where that would have ended up at.

On the second pass I ran 141 mph. Added two more degrees of timing but it lost traction about 4500 rpms in first gear and it short shifted into 2nd way to early. My 1-2 shift is supposed to happen at 6400 rpms so the truck really bogged down at the bottom of second when it happened. Put a few bus lengths on a camaro that probably trapped 130 something.

Even with my proven ice cycling and packing method, I quickly found out that IAT2s can become a pretty significant issue beyond the first 1/4 mile. In addition to the long staging lanes where I was almost constantly idling for 30 mins straight, I simply do not have the fluid capacity to support a run that long. Even with my switch that shuts off the I/C during the staging process, IAT2s reached 180 on the first pass, and went up to 250 on the second pass :shocked003. Needless to say, some improvements can be made in this department. BTW, this was with water/meth spraying through a -10 nozzle as well.

The truck ran perfectly though! For a street driven 10-second quarter mile truck that ran the half-mile with no other modifications, I couldn't be happier. I drove it the two-hour 120 mile trip there and my wife drove it home. Not a single mechanical issue.... except now I need new some new MT drag radials.

I highly recommend that any who has the chance, to participate in a half-mile event. :smt023

The whole reason all of you clicked on this thread... here is the video of my second pass :smt023

What gear do you finish in? I am assuming you still have the 4R100?

How do you go about switching into O/D without blowing things apart?
Do you let out hit the button and get back into boost? Thats what I do when I get retarded (not to often anymore)

Thanks everyone!

Yep, stock trans and 3.73 gears, I was winding out 3rd to 6100 rpm when I passed the 1/2 mile marker.

What kind of ET's were you seeing?
They didn't give us ET, but from the video I could infer about 15-16 seconds

Nice! And what does your truck run in the 1/4 mile?

On 22psi it'l run 10.8 @ 125 and on 17psi it'll run 11.2 @ 121... But I've never run it at 19psi in the quarter, so I assume it is somewhere in the middle of those two.

Sweet, Congrats thats movin for a street truck :) never got to hear 1 from outside at that speed, but been told I could be heard a ways off on spirited trips LOL now I know
could get some good hits if you forward to Speed Society, they are involved with a lot of the 1/2 mile events in the midwest & out west, and are always growing
http://speedsociety.com/ they also have a FB pg

How was traction? That will affect top 1/2 mile speed to some degree.

What plans to mitigate charge temp issues?(I see you shopping 4v heads, so I suspect turbo)

Traction was not great. First pas was okay, but second pass with more timing it broke loose about 4500rpm in first and it short shifted into second. I looked at the datalog again yesterday... When it short shifted into second it bogged down to 2500 rpm. Ran 141 on that pass. I'm sure it would have been 146-148 had it not done that. Looked like they were spraying down VHT in the morning but stopped in the afternoon.

You called it Jim. I love the power level I'm at, but it just isn't sustainable on the street unless it is below 60deg out. Especially if I'm going to participate in more half-mile events or anything under sustained load. The cooling system just doesn't have the capacity to remove all the heat added to it.

I'm going to take my time, piece out all the blower stuff and work with some of the fabricators here at GTRI to build an appropriate kit.
