I finally got my fuel system installed. I ended up going with one of the new Air Dog 4g units. I know airdog has a HORRIBLE reputation but I have heard that they fixed all the issues with this latest design. I guess we will see. The main reason I ditched the 6.7 pump is because I wanted a very clean professional job and I did not have time to piece everything together the way I wanted it... and I did not want a bunch of hose clamps holding my fuel system together. The Air Dog 4g unit was pretty easy to install, the kit was very well put together, and I could get it quick... I was in a hurry to get ready for a little dyno event. It went together really easy and so far works perfect. It seems to hold full fuel pressure on my all out race tunes so far.
The local Dyno event at rowdy racks was a lot of fun. It was very cool to meet a bunch of the local guys in person. There was an issue with the first truck falling off the dyno LOL. It scared about half the people away but some of us stayed and spent the day talking trucks and running on the dyno.
The disappointing part was the dyno was reading WAY LOW. About 70-100hp low from all we could tell. It was not just a few people disappointed with their trucks. It was EVERY SINGLE TRUCK reading low. Many people had been on a dyno previous and some even had been to the track and everyone agreed the dyno was way off (oh except for the dyno operator LOL). He was also struggling to load up the trucks on the dyno and did not really seem to know how to dyno them. He was not running a fan up front for the first half of the trucks (and then the one he did use was not doing much). He kept mashing the pedal right at the start of the runs and all the trucks kept downshifting, so he would start some of the dyno runs at 2800rpms. :banging:
I am pretty sure he was more of a gasser car guy... not a diesel guy.
Here are some of then numbers we were seeing.
6.4 trucks fully ******d running 300hp tunes were only hitting 450-490hp and 600- 700ft lbs of torque (not one broke 500hp)
6.0 trucks with stock injectors, big tunes and turbos only hitting about 325-370hp and less that 500tq (only my 6.0 truck broke 400hp)
7.3 semi-stock trucks with tunes only hitting 220-250hp
7.3 truck with 238/100s and s366 that only hit 398hp
6.7 psd fully ******d with twin pumps and s366 that only hit 513hp and 540tq
My truck was the highest hp at the event with 547hp
A few other guys had previously ran their trucks at the dyno/track and the numbers seemed about 70-100hp low, so... Cory at Diesels and More threw out the idea that we could check the numbers on our dyno so it motivated us to finally get our Dyno up and running for our first truck (oh ya we bought a dyno). We hooked up a few last minute items and ran my truck on our own dynojet later Saturday night.
:redspotdance:
627hp
1032tq
:toast:
That is more what the truck should be doing... I think with a descent fan to actually help the intercooler and using the load cell we might pick up a few more HP.
Here is the dyno graph
Here is a pic we took right before strapping the truck down
Here is a video. Truck cleans up the 205s to almost nothing once the turbo is fully spooled. I think the 30% nozzles are maxed out. Probably only pushing 190cc

Overall I was very impressed. Now it is time to fix the 4x4 and back the numbers up at the track.
