His truck is amazing, was very fun watching that build and his results are fantastic. I hope to be able to have similar results even though, as you will see, we are doing a very different build.

I tried that as well, just didn't take a pic of it. I have ran this turbo before and max and I live at very different altitudes. It really sucked running before as far as street driving. Hoping this spool valve helps with that.

Sorry i must have been mistaken for some reason i thought there was a longer tow portion. :bang

What?
The GTX42 is the big thing I'd change right now. Looking at the past competitions, the big hp trucks usually only win the dyno, the lower HP trucks with quick spooling turbos seem to do the best in the rest of the categories where response is crucial and traction is often limited. Hopefully the spool valve works for you as intended, but I'd be leaning towards a smaller secondary.

Put a roll bar in it so you can go faster in the drag racing portion and don't get disqualified.

Brap.
If NHRDA let him run 11.0's I would say that is already taken care of.

^^this. Maybe something that will spool a little quicker.

Finally Todd had the bright idea to modify the spool flange and drill new holes to mate it up to a used Straight T3 Flange Steed Speed manifold he had laying around. After some drilling and port match work, he got the spool flange and GTX4202 to fit!
We ended up with the GTX turbo reverse mounted on the straight flange T3 Steed using a BD spool flange as a T3 to T4 adapter, quite the configuration of parts!
With the GTX turbo mounted in it's final location, Todd started to fabricate the hot pipe and work around other obstacles in the engine bay.
A few extra bends in the hot pipe to get around the stock shock tower. If the motor ends up torquing over too far, we'll have to come up with a flat short shock tower with custom shorter shock or semi-rigid motor mounts. It's amazing how much the motor moves on these motors when they're loaded down all the way in a race.

Nifty!

The GTX4202R has been tested at high altitude by Todd both with and without the spool flange on this very truck, tranny, and motor combination. We're confident that it will work. However, it has not been tested with two S475's down stream in the exhaust. There is roughly 6 months between now and the Diesel Power Challenge, if it needs to be changed for something different, there is plenty of time to test and tune between now and May 2015. All constructive criticism is appreciated and helpful. We don't know it all, and we never will, but some areas of this build have been tested and tuned in prior experiments and that's why this aptly named truck: Frankenstein is going to be one of our latest and greatest creations!!!
Hopefully it behaves similarly in a triple setup as it did in a single turbo setup.

The boost from the atmosphere compressors pushing on the manifold turbo will make it both spool, and come on slower than as a single, but it still should work, I think. It'll be neat to see a mechanical truck take a run at it, it's been a long time coming! Hopefully with a build thread, that'll help you get voted in...
Me, I liked the days where the staff could pick trucks with dictatorial impunity

Correct, this truck will be properly equipped to legally run all-out in the drag racing portion of the competition. Todd and I are both drag racers at heart, if there's one portion of the DPC challenge we want to be extremely competitive, it's the drag racing event.

Just going off of past trucks with big setups. Seemed spoolup hurt them. If your setup will work that would be great. Sounds like a nasty build. I will be following for sure. Good luck!
