WWG2 Test - Stock F350 Dually

Here are some more test results of testing with the WWG2. The test vehicle is as follows:

2003 F350 CC, Dually 4WD, VDH5 (TNAA7S3), 230K miles, Injectors and HPOP replaced 6 mos. ago. Otherwise, the truck is completely stock.

As usual, testing was with 8000 Lbs load on the dyno. All runs we competed in 3rd gear locked. Speed was held at a steady 1400 RPM until full throttle was applied. Data sampling was taken from 1500 RPM to 3500 RPM. All testing was achieved with engine and transmission at normal operating temperature with 70º ambient air temp. All runs were datalogged to obtain boost and backpressure readings, along with monitoring EOT, ICP, IPR, and other critical data. Unfortunately, this vehicle was not equipped with a pyrometer so we were not able to observe any changes in EGTs. Datalog pressures were verified with a mechanical boost gauge and are considered to be accurate with +/- 0.25 PSI.

Generated results are as follow:

Stock ECM calibration (minus Speed Limiter and Rev Limiter) - Stock wheel vs. WWG2

Boost:

• Stock:
  • 7.8 PSI @ 2000
  • 14.3 PSI @ 2500

• WWG2:
  • 7.5 PSI @ 2000
  • 14.7 PSI @ 2500
  • 19.8 PSI @ 3500

Backpressure:

• Stock:
  • 11.9 PSI @ 2000
  • 23.9 PSI @ 2500
  • 31.1 PSI @ 3500
• WWG2:
  • 10.6 PSI @ 2000
  • 23.3 PSI @ 2500
  • 33.5 PSI @ 3500

We will be testing another S/D vehicle later this week (Friday) and will post up those results as well as they become available.

Impressive results

Wonderin what some hot tunes will bring.
What dyno is this on, almost 300hp /625 tq on a tow tune ?

am i reading a 15-20hp gain in the stock file? just by swapping wheels????

live life full throttle

and a 200ftlb tq jump from stock to tow setting?

live life full throttle

That tow file must be strong......

all dyno's are gonna be different. but regardless, on that dyno the hp diff and the tq diff between stock to a tune with the ww is a big jump. its not like bill changed the parameters of the dyno between runs... should be able to see those gains on any dyno, but prolly not the same numbers.

live life full throttle

Why no big tune ???

Numbers seem higher than what ive normally seen. But the 5th graph....

Stock.........................230/475
40T &WW..................295/625

65 hp / 150tq gain

Thats a big deal with a billet wheel.... Im in for More!

thats an awesome gain.

Given the math, this truck on a hot tune ?.......... Ummmm... 360hp/720tq ???

Where's the evidence supporting that?

Good results! Can't wait for the 6.0 wheel!

Bill tried his hot tune...the truck wouldn't hold ICP.

Thanks for clearing that up

Like Jon said, we tried a 120 tune just to see what we could manage and the ICP completely tanked. Couldn't even make 1800 PSI and IPR was pinned at 94% at the tender speed of 1900 RPM. Even the 40T tune was causing a P1211 to pop up. Given that, imagine what this truck would do if it was actually holding pressure! :drool:

The dyno is Mustang Dyno MD-250 Load Dyno. We keep the dyno calibrated regularly and nobody has ever really had a dispute with our power numbers.

Yep, that's what we saw. I'm pretty astounded by it myself. Now somewhere it was posted that the wheel is something like 20+ grams lighter than the factory cast wheel. That, combined with a bit more pumping efficiency could certainly account for the gains. We're going to try this on Jon's truck This Friday and see if we continue to get similar gains.

I'm also curious as to what the truck would do with a modified W/G controller like a TurboMaster or Banks BHA. I'm sure it would have some penalty on the Backpressure, but wonder how it would affect the boost and power. *SIGH* Things to investigate in the future. imp:

----------------

Anyway, just to clarify... The graphs below show the 40 Tow tune makes exactly what it's supposed to - 40 HP - at least before the stock tune starts to defuel and the power gains jump significantly. Here are the graphs:

This is perfectly in line with what we normally see for a 40 Tow program on an otherwise stock truck.

Take care.

just by swapping wheels makea a 20hp jump... thats sweet.

Bill, how would a stiffer canister actuator or the turbomaster negatively affect the backpressure?

This might be the little something my 7.3 needs.

Because it would hold the wastegate closed longer...
