Are there any rules that dictate the year of the vehicles racing? I wonder what class a new Ford F-150 with EcoBoost would run in, and how it would do. EcoBoost is a 365 HP 3.5L V-6 with twin Turbo Chargers. It is basically the SHO or special police package engine.

The classes are broken down by body year,body modifications,engine size ,fuel and blown or unblown. I dont have a rule book in front of me so these details may be a little off but 1900-1948 run vintage class, 1948-1981 run classic and 1981 up run Modern class. Production can have no aero mods that are not factory thru with classes in between all the way up to streamliner. Engine sizes are broken down into ranges and given a letter designation. AA over 501 CID , A class 500 inch and under, B class 373-439 CID, C class 306-372 all the way to K class up to a whopping 30.99 cid. Next is fuel which is either sealed event racing gas or you run fuel class which is Nitro,ethnol, methanol,E-85 or N20, Diesel might even put you in fuel class unless you run specific diesel class. Then you have blown or unblown and that includes turbos So long story short the f-150 if it is factory stock except for safety mods and engine up grades and runs on event gas should run E/GBPP.

E-between 3-4.2 liters

G-gas

B- blown(turbos)

PP Production Pickup (unaltered factory aerodynamics)

The blown production E engine records are above 200mph. An ecoboost truck will not touch that without serious work. The engine probably can't even support the power required to be a serious contender.

Thanks for the information guys.  I know Banks has turbo diesel trucks running 200 MPH. Taurus SHO's can go 140-150 and a lot of new cars have computer limited top speeds.  I think one of the reasons is the speed rating of the tires.  Is there a ball park estimate of how much slower a truck with comparable horse power is than a passenger car?

Thanks,

There’s a 40+mph difference between Tim’s truck and Keith’s car out on the salt.  And while some of that is attributed to the horsepower differences in the engines, flat plate aerodynamics would still account for maybe 25-30 mph.  That’s just a wild guess on my end but maybe Tim can give a better number.

It's a very hard comparison since there are so many coupe and sedans to choose from but when it comes to Production classes the record for D/PP (261-305ci production pickup, my class) is 164.230 mph and the record for D/PRO (261-305ci production coupes and sedans) is 225.336 mph. It's an "apples to oranges" comparison at best but that's how it reads.

I might add that as the engines get bigger the gap gets smaller. A/PP is 202.113 mph and A/PRO is 242.011 mph.
