Send it to MPR and tub it and 4 link it. Put a clutchless 5 speed in it with a 5.4 supercharged motor and go super stock racing. That was an easy question to answer.:D

Fuuny you should say that. I spent approximately 30 minutes on the phone with Mike on Wednesday :D

Old cars were rated differently (gross hp) from the factory with no engine accessories and free-flowing exhaust—new engines are rated with everything in place, including emission controls.

The way Ford did it was there were 3 Horsepower ratings.

A curve was no accessorys (fan, alt, water pump and open exhaust)
B curve was some accessorys (somewhere in between A curve and C curve)
C curve was with Fan, waterpump, alt and exhaust back pressure as installed in vehicle. This was the factory published rating.
all the above were corrected to SAE J 607 which was ans is 29.92 baro, 60 degrees carb air.

Mose Noland could give you more of the details if he remebers

That is true of pre 1972 cars Ralph, but after that they were "net" with everything installed as today. I used mostly mid 70's cars for that reason.

Regardless of how, or who done what, potential is what a class racers is after.
If eng A is rated at 99% of it's potential, who going to try it? Nobody.
If eng B is rated at 50% of it's potential, everybody will consider it....unless it's hidden, then only Billy Nees or Bob Shaw will find/try it! LOL!

So the only real question is then, what is the true potential of the new motors?
Then, can they be factored the way the old motors were?
In other words;
A is 400hp@ 80% = 500hp 100%
B is 400hp@40% = 1000hp 100%

If both engines start out at .58 factor, one will obviously cause a ruckus.(as we have seen with turbo or supercharged engines)
So, do you rate older or N/A engines at .58 to start and pressurised eng 1.1 to start?
What is a fair place to start pressure engines? Maybe starting them at 1.3hp/cu.in IS fair?

Re: 2012 Boss 302 in NHRA Stock Eliminator

This was still going on in the early 1980 as I was involved with a program that they called Stock Engines, Ford would buy cars from GM, Chrysler and other manufactures run Performance, Fuel Econmy, NVH and Emission Tests then pull engines out of vehicles run them on Dynod then send to Engine Build-Up dissamble and measure them. Then puld a report on each vehicle.

The new Boss 302 is about the same as the Cobra Jet 302 except the Cobra Jet has more compression. The Boss is rated at 444 hp from the factory and the Cobra Jet is 325. I just watched a test on Motorweek of the Boss 302 and it went !2.4 seconds in the quarter at 124 with street tires and full exhaust. Evan you can forget the weak BS all these cars are bogus and way under rated.

Re: 2012 Boss 302 in NHRA Stock Eliminator

It's probably because the motor in the mustang has zero drag racing development done to it and ours has over 20 years worth. I guess the reason there is only one other car in the country with our combo is that it's so under rated. We'll be hard pressed to out run it once it's got the right converter and cam and all the other things you have to have to run fast.

It is rated from the factory at 360 and NHRA rates it at 325?

How did you get NHRA to take 35 horsepower off of the factory rating or was it always like that?

Re: 2012 Boss 302 in NHRA Stock Eliminator

It has been 325 for quite some time.
