Competition Street Diesel vs. Modified Diesel

[GOT-Torque]

I've noticed that at some local area pulls they only have two diesel classes, Street or Modified. Can anyone provide some general info on the difference in the two? What are some obvious changes that push you into the modified class?



I know that every place has different rules so your rules may not be the same as these, but I'm just looking for some general info.



For example, does a twin turbo setup automatically push you out of a street diesel class?



Thanks

i think the way it works is that for street class it must be street legal (license, insurance, ect), single charger, street tires, no major suspension modifications, must have at least 1 inch of suspension travel, other than that i can't remember much that makes the 2 classes different, and as you said rules vary as to where you are and how picky they really want to be.

we have 3 classes here in ohio street stock, pro stock and modified. street pretty much the same thing kissfan said. pro stock has the same rules as street but they are allowed to use water injection and they can have as big as single turbo as they want or a small set of twins. modified class your allowed to have a solid supension,cut tires, and as many turbos as you want and as big as you want. the only rule they really have in the modifed class is that you aren't allowed to use nitrous or propane
