"Mobile DYNOJET 1800HP Chassis Dynotuning"

Welcome to X&M Hot Rods, Inc., home of the Mobile DynoJet. At X&M Hot Rods, we have the expertise to meet all your high performance needs. Automotive enthusiasts come from all over for  our products and services. Not only do we sell performance products, we install and tune them for "The Horsepower you want, and the reliability you deserve". We feature a 2WD Mobile Dynojet Chassis Dyno & Winpep6 & 7 to help you get the most out of your equipment. Combined with our Diablo onsite chip burning and automotive computer programming we can get you maximum performance for the product you choose. We have been tuning EFI vehicles for 5 years but we still tune carburetors! Please click here to learn more about our tuning services.

We specialize in making power using "power adders" such as supercharging and turbos. Using these technologies, along with modern engine control systems, we can achieve levels of horsepower and performance that were previously the stuff of dreams. But now you can have it all: incredible horsepower along with drivability and reliability. The use of water injection and dual power adders (combining nitrous and supercharging) make a lot of power together. We can get and supply custom camshafts for both street and race use.

What We Do:

Using our two wheel drive Dynojet Chassis Dyno we can instantly graph your horsepower and torque increases while we tune.  We have found that Dynotuning is essential to achieve "the performance you want and the reliability you deserve". Our dyno is the first in our area. We have had nearly every type of car on our dyno - from 4cyl. to big-block V-8 race cars. And we can also test and tune motorcycles on our dyno. Everything from stock bikes, to Harleys, have been on our dyno.     

According to one of our customers "it would have taken all season to achieve the results you obtained in just a few hours on the dyno...thanks for the great work. I'll be back next year!" We have found that it is futile to try to tune for maximum horsepower by the "seat of the pants". Differences as large as 20-30rwhp or more are simply not apparent to most drivers. In addition, testing on the street is dangerous and usually illegal as well. Trap speeds are a better indication of horsepower but both track and street testing aren't safe for your motor. While anytime you push a motor to the max there is a risk of damage, until you get your combination dialed in testing is much safer on a fully instrumented dyno.

Thanks to computer software from Competition Data Systems we are able to simultaneously map the following and plot against rpm, time, and wheel speed:

• FUEL PRESSURE

• INTAKE AIR TEMPERATURE

• BOOST/MANIFOLD PRESSURE

• EXHAUST GAS TEMPERATURE

• AIR FUEL RATIO

• HORSEPOWER AND TORQUE (plotted against speed, rpm, and time)

• COAST DOWN TESTING TO DETERMINE DRIVE TRAIN LOSS
