Just came from the Dyno.

Here's what I got:

238.1 rwhp @ 2900
371.4 rwtq @ 3900

The car is a '95 5spd with Under drive pulleys, a 10% overdrive super chareger pulley, MAC intake, 2-1/2 true dual exhust.

I've got to work on the 1/4 mile now!

Nope I think his numbers are right on. My torque numbers were way higher than my HP. But that's a helluva lot of torque. you sure you read the graph correctly? One side is HP th eother is torque.

Yeah YOU all must be right. I saw the #'s read the chart. Are you saying the guy who works the dyno is also reading it inncorrectly? What about the 15-20 other people who attended our dyno event.

What was I thinking YOU all must know more than what I saw.

204, 320 NOT MY CAR pr!ck

what hes saying is that if your dyno looks anything like a normal roots blown 3.8, you have to be getting your RPM backwards in that first post, otherwise instead of looking like this, even with the numbers you have...



it would look like this...



you see,
238 hp @ 2900 = 431 lb-ft @ 2900
371 lb-ft @3900 = 275 hp @ 3900
not to mention, thats not the kind of flat torque curve you would expect out of that motor.

but if instead you simply got the two rpm backwards, like rancherlee suggested, you would have,
238 hp @3900 = 320 lb-ft @ 3900
371 lb-ft @ 2900 = 204 hp @ 2900
which is alot more realistic, especially of a blown 3.8

and likewise, if you did indeed get the numbers you claim, you would not be showing off the 371 lb-ft that you got at 2900, youd be bragging about the 431 you would have gotten at 2900 and instead of showing us the 238 you got at 2900, youd likely be braggin about the 275 you got at 3900.

theres also no need for name calling

EDIT:

looky what i found, right from the horses mouth, so to speak

4. Ryan Harris 1995 Thunderbird SC 3.8L V6 SC - 5 speed 238.1 @ 3200 371.4 @ 3800 Sept 2002
thats a little more like it, but still strange because 238 hp @ 3200 rpm would be 390 lb-ft @3200 and 371 lb-ft @ 3800 would be 268 hp @ 3800. id like to see a scan of that dyno graph. out of that whole list of people that went to the dyno, yours is the only one who he wrote down as having a torque peak at a higher rpm than your horsepower peak. that should raise a red flag and make you and the person who wrote the results take a second look at the chart.

my biggest point is that if you did get those numbers, those numbers wouldnt be your peak numbers and you would be braggin about something like 430 lb-ft and 270 hp. do you see what im saying? im in no way impying that you didnt make 238 hp and 371 lb-ft, im sure those numbers are correct. im just saying the rpm at which they came seems a little off.

Bump for Ryan Harris' Avatar! What ever happened to the days when everyone put their dyno sheets into one thread. Now everybody's special and needs their own Dyno thread. LOL

Anyway, I got back to the Dyno today and although the TC was slipping the car managed a 444.73 rwhp / 436.6 ft lbs of TQ. Next up is a new Circle D converter. Time for the DirtyDog TC to find a new home. I thought it was a tripple disc but Rob says it's only a single. I shot some video that I'll edit and post later. I also took home the "Best in Class" trophy for the "Other than Mustang and not-an-F150 Lightning" class.

Thanks! Yes. I believe so.

I have one of Allen's (DirtyDog) 9.5 Billet - Single Disk converters in the car with over 100 track passes on it. It's time to upgrade to a Triple Disk Circle D converter with a mechanical diode.

I'm looking at this one @ 3,800 to 4K stall: https://www.circledspecialties.com/4r70-pro-series-245mm

I have that converter in mine now, albeit it's the single disk and midrange impeller for a mid-3k stall.

You'll like it. :)
