T=757lb-ft@1900rpm

P=296hp@2350rpm

387/858

You are looking for a first gen guy, they will have the lowest HP and GOBS of torque.

The last time I dynoed, back in April it was 387/974



My neighbor 2 weeks ago was 335/1042





Later, Rob

At Scheids I dynoed 332hp and 920 ft lbs first day, 2nd day hp numbers were alot higher (what I noticed).

196/572 at Scheid's a few weeks back. Funny how those two figures can be so far apart. They told me this was at rated rpm of 2500. Peaks were 204/606, I have turned up the rpm to ~2650.

years ago

Car and Driver or Road and Track (back when I was into that stuff) did a "road test" on a D9 Dozier.



If I recall correctly it had something like 180hp/2000fp. How's that for outta kilter?

Can anyone share some insight as to why there can be such differences? I know that turning up the RPM's will result in more horsepower, while torque remains the same. But what about the other way around, high torque and low horsepower? I dynoed a while back and turned 203/421. JFitzgerald ran 196/572. How can the numbers be so different for two rigs that are quite similar? My numbers are before intake, exhaust, RPM, timing, and injector modifications. I am hoping that my other mods have really improved torque. I will dyno again at BD this fall or spring. I am too cheap to pay for a dyno run. Any ideas would be appreciated.

Mike, the other guy is adding more fuel early. More fuel and more air will make more torque.

HP= Torque X RPM divided by 5252.

Torque = H. P X 5252 Divided by RPM



Since torque and hp is a mathimatical formula, more torque really means more hp at lower rpms. Think of the power curves and several different ones. Like a narrow powerband with a steep curve, would seem to me to have low torque reading where a wide fat powerband would have more torque for the same hp reading.



-or-



400hp@2600 and 1000 ftlb@1800 = 342. 7 hp @ 1800 rpms

400hp@2600 and 800 ftlb@1800 = 274. 2 hp @ 1800 rpms



Of course this is just an example.

 

[power grizz]

had 215/800 just with the screw turned in, an hx 35 and a big custom intake. no intercooler.

 

[BushWakr - RIP]

225. 2 HP@2200 / 737. 5 Tq@1480



Go figure...



Bob.

 

[DarrellB]

245hp / 849ftlbs of torque



That was on the great dyno they had a Muncie this year.



Those #'s are higher now.



Come to think about it the HP # went up a week later on a different dyno. Those things are an accurate messure of how much power you have too. If someone knows what they're doing they can make a dyno say about anything they want.

I COMPLETLY agree!

 

[Old Smoky]

More fuel early means more torque? Well I'm sure I've got plenty of it now. When I dynoed the first time, smoke was very minimal. Now I can really make the smoke roll (I can also drive it so it won't hardly smoke at all). Hopefully max torque will be at a much lower RPM. I dynoed on a Mustang the first time, and will again the second time. So, the numbers should be comparable. Thanks guys.

Does an electric motor count? Doesnt an electric motor have peak torque at 0 rpm, which would be 0 hp?
