If you follow the 20% increase at the crank that means my truck is 388hp at the crank. Well 388.8 which is down 1.2 hp from the stock advertised horsepower.
Anyone can add my mod list up and see the amount of money I've spent to loose 1.2 hp. If you where just going off Dyno numbers it doesn't make any since, my truck is faster than the day I bought it. But that's just my butt Dyno, no data to prove it. In fact this Dyno shows I've spent a lot of money to make my truck slower.

You made 324.81 rwhp. If you are using a 20% drivetrain loss estimate then that means your making 406.01 at the crank not 388. Dyno's all read different anyway. I wouldn't lose to much sleep over the numbers. Ive dynoed/raced tons of cars, sometimes the dyno results are way high or way low compared to the et at the track.

Here is a video of my old car (sold it) on the dyno.

My buddy has a very successful performance shop and knows his stuff. He has a Mustang dyno and he says everyone wants big numbers but the dyno is a tuning device and too see what addons give you. He says the 1\4mile is the real test. I agree

this is my result, I made it today:
DSC_0009.jpg

I have:
- VR Grabber
- PTB 87 mm
- SW 1.875 long tubes and exhaust complete
- Diablo with HF
There was Diablo 93 octane installed and 93 octane inside the truck. I find the results as very good. It means there are magic 500 on the crank ))
And there was also a problem that the mechanic couldn't catch the real moment of downshift, so in a theory, if we'd try more then 10 times nay be we could gain 400 RWHP
Also I will configure HF and lei it be tuned by HF - so there will be some HP gain too. But generally I'm very satisfied - the truck is pulling from 50 mph as a bullet compare to stock one. I didn't make professional measures but got 6.2 sec to 60 before right tune and do not **cking the tranny.

Damn that's awesome if that's accurate. Do you have a stall converter?
I would like to get my truck dyno'd but I hear it's next to impossible if you have a stall converter.

Bull, all automatics have torque converters, RT's have a higher stall than a stock, but race cars get dyno'd all the time with torque converters.

I remember seeing someone who was having a real hard time getting an accurate run. And the graph was all over the place.
I may be totally wrong haha

What does PS stand for?
Your mods will never make 392 HP at the wheels.

PS is HP in Europe. There may be a variation in how ps is measured compared to our hp...

I agree. I too doubt the accuracy, even with those mods. Plus, if that was accurate, the 0-60 would be much quicker than 6.2 seconds.

I wish it was accurate, that would be awesome! :)

392.6ps is roughly 387hp.

That being said, I'd be shocked to see a hemi with vararam, header/exhaust, tb and 93 tune pull off 387hp when they come from the factory with 390 at the CRANK, which should equate to ~312rwhp assuming only a 20% drivetrain loss. No way those mods managed 75hp.

google search convert ps to hp :winner_second_h4h:


PS is just metric horsepower. So in general it's about a 2-3% difference.
