Holy Shat - 1200 PS Shelby

4 liter Whipple on a superflow dyno


A country worth living in is a country worth fighting for.

DAMN!!! Thats impressive, do you know the setup? I just put a 4.0 Whipple in my GT500 so i want to know what it will take to get it there!

Top graph is not hp but torque; nm. 1277.9 nm is 942.6 lbs-ft. And since the 1005.7 is in ps (for pferdestarke), it's 991.92hp. Also, DIN ps is on the crank, rwhp is the graph noted RAD_L (for rad leistung), which means that in this case it puts down 883.9 PS, or 871.9hp to the rear wheels.

Edit: Not trying to be rude. Just trying to clear things up. A 4.0 Whippled GT500 is a spectacular beast indeed.

I was wondering what the measurements were. But if what you say is accurate (and I have no reason to believe it's not) shouldn't the nm line intersect the ps line at 5252 RPM?

 

[Rasmus]

No, you have different units of measure. Convert the values you read off of the graph at 5252 rpm to hp and lbs-ft, and you will get identical numbers.

For instance, I'm reading approx. 955/1275 ps/nm at 5250 rpm. Converted that's about 940 hp/lbs-ft.

Bear in mind that the two DIN graphs are calculated flywheel numbers based on the RAD_L graph.

Why do they not use the same measurements ? No horses in Germany?

Think of PS as the German version of metric hp. Hp over here is usually mechanical hp. That said, most manufacturers use kW these days to avoid confusion between hp and hp.

I AM NOT IMPRESSED IN THE LEAST. TOP FUEL DRAGSTERS MAKE OVER 8000HP.


lol

 

[GallopingFord]

whatevs, my radio flyer has 1000hp

 

[Drex]

Thx Rasmus. I misinterpreted the data when I saw it. Schropps has tuned my car and I follow their FB page. When they posted the graph I thought I would share.

Still, 991 HP is nothing to sneeze at.

Still impressive, I'm surprised those Germans knew what to do with a Mustang.
