It was good to meet you and talk with you for a bit, Will.
 
Hey Will you remember a few years back when we were fighting for 11s? Look at us now haha. Crazy how things have changed. Time for 9s I guess right?

a bigger "small" turbo to get rid of some back pressure,
a slightly bigger "big" turbo and a real p pump ought to hit it home in a hurry.

sure some more weight can come out too!
 
The grimy fingers and the possessed look on his face are the tell tale signs of a true racer, or someone not quite right in the head HAHAHA

I still remember when will rolled out with the "trash can" stack in the back of his truck for the desert diesel nationals a few years back, the crowd was like DA HELL IS THAT LOL LOL LOL
 
I filled the fuel tank to the very top right before the event. Based on previous race weights and the fact that the driver (me) is a bit heavier than last time on the scale, I'd estimate the total race weight right around 5525 lbs. I do have over 100 lbs of steel ballast in the rear of the bed and both bumpers so there are lots of areas that can be reduced to get the truck closer to the 5000 lb weight limit for 2wd in the super street class.


Before when it was running 11.50 @ 121 MPH around 5400 lbs, it calculated to 649 HP average and put down 708 HP peak on the dyno. In my opinion, those numbers jive well when you look at the RPM ranges used at the track and my power curves from the dyno.

Now with it running 126 MPH at 5525 lbs, it calculates to 750 HP average for an average gain of roughly +100 HP!!! For the sake of testing, I will make a run at Las Vegas with the old DDP 024 DV's so I can get some comparison numbers from the motor work alone.
 
Did the slicks cure all the traction problems? Have you thought about moving weight such as the batteries and maybe some kind of fuel tank behind the axle? You are also getting up the roll cage speed also don't you think? Keep up the good work, this has been one of the best write-ups of any I've read.
 
Thats impressive, comp DVs were only worth 6hp over 024s on project triple threat. If thats the case your mods made a bunch of power! It sounds like it could make 800 in the right conditions on the rollers

Yes, it needs a roll cage, 11.49 and quicker is where NHRA requires a roll cage. I have one, birthday present from over a year ago!!!, just need to install it.

As far as traction, my best 60' prior to the last event with the identical suspension setup was 1.73 at Las Vegas during a semi-prepped test n tune event. The track at Famoso was exceptional on most of my passes, especially if i got to make a pass right after those Pro Mods!!!

I still spun every single pass, even on my best 1.65 60'. I never tried launching at less than 18 psi so it might have done better with a slightly softer launch. I tried 30 psi and it spun really bad and ended up with a 1.73 60' on that pass. What's funny is the truck almost ran the same 1/8th mile ET because the higher launch reached full power much faster in the run.

I think with a generous dyno, 800 HP is possible. On the comp cut difference, if triple threat was out of air, comp cuts could potentially reduce power. Another variation is regular comp cuts are narrowed down 181's or 131's with a .076" to .084" wide shoulder. My comp cuts are narrowed down version of my 025" DV's with a .025" wide shoulder. I haven't tested side by side, but all comp cuts are not equal and it's hard to say what specific size of Comp Cut was tested on Jason Sand's triple threat vs. my 025 Comp DV's.

industrials dyno event is in may, probably hit 1000 up there!

Good idea, I need to make sure they use the Custom Auto dyno with a healthy 13-15% correction factor!!!

What size injector did you end up putting in?

I'm still running the same 5x.018" VCO 145* injectors it's been running forever. I have bigger injectors on-hand ready to install, just need more bracing on the high pressure hot-side boots or possibly upgrade to some nice aftermarket boots before I try to add more fuel. I have to admit I was amazed how much more smoke from top-end fueling I picked up from my Comp Cut DV's. If I can pick up another 20-30 cc's with some full cuts, and another 40-50 cc's from some 5x.025" injectors, I might have enough fuel to make 900 HP with this 160 pump.
 
Custom Autos dyno has a big correction factor cause its usually 80-85* with 2% humidity so that makes the DA here about 9000ft elevation, than factoring back down to sea level.

^I'd definitely recommend getting a noncorrected print out if you can and looking up the DA online:
http://airdensityonline.com/results/?trackname=Bandimere%20Speedway

Then do an SAE correction yourself. I know when I was at ATS's dyno, they had a correction factor of 27%... WAY too high.

I don't even consider corrected numbers. I wanna know what the truck makes at our elevation, not sea level. I don't live at sea level. Haha, know what I mean?

Agreed 100%! I only care about what it makes exactly where I'm at. It's a good way to relate it back to people at sea level who have never been to elevation though. Otherwise they are confused why your truck is so slow...
 
Finally found a video of the burnout contest, although it doesn't look too spectacular, I did hit 4600 rpm which calculates to 181 MPH on a set of old dry rotted 285/75/16 BFG All Terrains.

The motor didn't blow, it simply shut off when it lost boost and still had full load from the brakes, overdrive, and lock-up.
