The Bullitt will do 150 mph!

Crimecrusher · Jan 25, 2002

I was on an wide open long highway the other night and thought I would open it up a little. I let off at 145mph and it was still climbing...I was coming on to traffic and had to shut it down. I will agree that this was a stupid thing to do but DAMM! this car is fast.

Sounds great, I had my Black #3667 on dyno
last week and they had it to 135mph in 4th gear at 6000 rpm.
It would have gone 150+ with no problem..

I did a 147 on the dyno and the motor was still pulling. I got out of it at about 5500 RPM.

You should be able to go quite a bit faster on the dyno than on the street: zero aerodynamic drag (I suppose you could simulate drag load with the dyno, though). Another thing about aero drag: it's a square law, meaning that drag goes up with velocity squared, which means you need a non-linear increase in HP to get a linear increase in top speed. Probably best to try top speed runs on a closed course, high-banked track (or the salt flats :wink: ).

Oh boy not this again.

WOW????? Makes sinse to me about the cars drag as it accellerates (spelling sucks)costing top end speed. But the dyno I was on does put a drag into the run 12 horses per 50MPH. Does that give real life drag on the car? I don't know, I just fix stuff.

Jimmy Ray,

The load would have to go up non-linearly on the DYNO to simulate aero drag. For example, 12HP for the first 50 MPH, 48HP for the next 50, 150 HP at 150MPH, etc. The only way to know for sure is to stick the Bullitt in a wind tunnel and measure drag load at various speeds. You could then program the dyno to interpolate between sampled readings from wind tunnel data. You could also estimate it using the stated coefficient of drag (CD). Anyone know what the Bullitt's CD is?

The bottom line is as you increase in velocity, your required horsepower to go any faster goes way up due to aerodynamic drag.

I rememeber a few years ago seeing a show about NASCAR that said at 200 MPH, their cars need roughly 10HP for every 1 MPH increase in speed. I guess it was the whole restrictor plate thing. So if the car needed 700 HP to run 200, they would need 800 HP to run 210.

I'm sure this is overly simplistic but illustrates that top-end speed can get very expensive.

Come to think of it, I don't think this has anything to do with this thread....Never mind. :smile:

I think we should all meet at the track there in taladaga Alabama, and see what are bullitts will really do. Somebody pinch me im dreaming again!!!

I live about 45 minutes from Talladega. I have often thought of how I might acquire some track time there. I would love to do a couple of hot laps in the Bullitt. I'm told you don't have to touch the steering wheel, in the turns, at 150 MPH. Don't know if I'd want to test that theory though.

Bullitt4075 · Jan 26, 2002

Your mission CRS2879,if you except it, is to take your Bullitt to the track and settle this once and for all...... as always if caputered during this mission any knowledge of your mission will be denied........ This tape self destruct in 5....4....3....2.....1 :lol:

The CD is around .034. That figure is what the sn95 were so, with our hood scoop it is probably a little higher. Still a good number I think. :smile:

A couple years ago, I had the opportunity to visit and tour the track at Talladega, had business in Birmingham. I was able to stand below the last turn on the infield and observe the banking. They don't use banking at that track, it's a farging wall!! The tour guide pointed out that you really don't get the feel for the banking when you are wathing it on TV. He's quite right! I would love to race my Bullitt around that track if for nothing else, to drive on the wall!! :grin:

Here's a link to a simple top speed calculator: http://home.earthlink.net/~jonaa/TSEX.html.
This is also interesting: http://web2.iadfw.net/nunnally/sts/performancesimulation.htm

Looks like the Bullitt can do right around 150...

Also read where it is relatively easy to get a sports car to 150MPH, but takes *twice* the HP to get to 200MPH... Sounds about right.

The Bullitt will do 150 mph!
