Are you ready for this? Say you wanted to get rid of turbo-lag on your diesel-powered truck. At the same time you'd get a colder, denser air-charge at lower boost pressures, reducing the unburned diesel going out the tail-pipe, and drastically reducing exhaust and engine-damaging underhood temperatures that cause pre-mature wear to many components? And how does getting an easy resulting total 900-1000HP in the process sound? Then you are thinking what Richard "Maddog" Madsen is.... IT WOULD BE GOOD.  We call it the Maddog Supercharger System :-)
Trading your turbo for a Maddog Modified Supercharger System means you can have FREE-FLOWING HEADERS on your diesel truck. Ditch the oil-cooler lines, wastegates, and compound set-up tubing. How cool is that? Really cool. Your diesel truck will sound and look like no other. And that is only part of the fun.

Stay TUNED for more details!

Diesel Power Challenge (DPC in SLC)

And they're off!! With the beautiful snow capped Wasatch Mountains for a backdrop, the Diesel Power Challenge by Diesel Power Mag kicked off with the first of a 5-part test of Steel and Diesel. And various chemicals. The temps hit 80 on this beautiful sunny day and fun was had by all, just see for yourself...


Tractor Pull, DPC style...


Even the Parking Lot was Cool...


Trucks weren't the only beautiful thing...

And diesel isn't the only way to get your motor running. A wink from Christine can make your whole day.


DYNO competition

Richard runs dynoAnd behind him you'll see the mighty F350 and our cute little Excursion with nifty graphics...



Last Dyno run of the day...and what a show they put on! There was a very bad noise on the second (and obviously last) run and then pieces of metal shot up out of the exhaust and rained down on us all. Fortunately, gravity helped them drive off the dyno...but we mourn the loss of their turbo.

We Know Diesel!

But we get all types here. Performance is Richard's middle name; and it don't matter if it's gas, or which decade... so we get to see all kinds of fun stuff here at Maddog. This week, for example...

We can fix that...

It says 427 on the outside, 460 on the inside...

and fun all over!

Diesel World Crude Drags 2008

The Weather Threatened for the Crude Drags in Bakersfield at the Famoso Raceway...we faced cold, rain, and sleet on the way down, but it made for a scenic drive

1262hp when last dyno-ed on pure #2, the F350 is still a daily-driver. A 10gal competition gas tank though means lots of stops on the way. Unfortunatley, the F350 was not fully ready for competition and Maddog MotorSports and Diesel Performance ran the Dyno instead this time...

Heavy overnight rains kept the track from opening until lunch time but there was plenty to see in the parking lot beforehand...


Trucks of all Kinds and Sizes

Banks uncovered...what makes it go fast? I see two turbos, low weight, wiring, and a bunch of funky tanks and fluids...


Orange County Diesel makes a Big Appearance


Fans of all sizes

Big Fans sometimes come in little packages



Banks had a very fast, very loud crowd pleasure, turning in its trademark 8.40 1/4mile at about 167mph...

Also a very fast truck

Fast and Green


A Day at the Dyno

Always a crowd pleaser, dyno runs loud and black!


Fire in the Hole!

Checkin in at the dyno table...check out his kid's fire-breathing truck in the next pic

Yes, that is flammage exhausting out of the to enlarge:
