I had uprev installed and had my truck dynoed and tuned today and my numbers were 270/310. Does that seem low to anyone else?? I would have thought my truck would be making more than that. It was hovering right below 90 degrees and humidity was 30%.
270whp 310ft/lb???

yea but if you notice thier is some ppl who think 317 horse power is at the rear wheel and not just the crank. for instance some ppl also think that a intake that says it gives you 15hp think omg my car or truck just went up 15hp and its like NO buddy if by any chance you got 3hp even that to the crank. you know were im going with this...but yea some ppl dont know about how hp or toque works...
I feel the same as u 08 The other thread they were talking about a month ago was mine and dynoed about the same and u can see my mods. I was highly disappionted in my numbers. I'm looking into getting a new muffler setup. but I need to get my to keep from blowing exhuast gasket for now.

Though I understand that, I still don't think I want to see the dyno #s. If you guys with an 07+ and UpRev aren't dynoing 300 rwhp, I don't want to know what I'm putting down with my 06.

It may be possible that some of the guys posting high numbers with light mods are embellishing on their numbers a little. That and the possibility of factory freaks.

Or the dyno operators can change the CF and have any desired numbers they wish..... But the track dont lie :teethmast

On 2 different dyno's at 2 different places Pinoytitan dynoed 321+ WHP with the same mods as me with the same truck....Float Test dynoed around 337 with PGM and Cams and Papa_D dynoed 340+ with cams.....I think it is Twisted Freedom who dynoed 290+ with just an exhaust or just an intake...I think high 260's to maybe a low 270 would be about right for an 04-06....Then again, weather, wheel weight, and the dyno all influence numbers...Most dyno's have a way of supposedly factoring out all those variables, but unless it is a well know performance shop with a great reputation and proven performance cars, I don't trust them.
This is what Wallace racing calculator has my WHP at:
Your HP computed from your 60 Foot Time of 1.92 at Weight of 5000 pounds is 314.55 HP.
Seems pretty close. I would expect I'm at about 320-ish, so that is close
Here's another one LOL...this is kind of fun:
Your HP computed from your vehicle ET is 306.03 rear wheel HP and 340.03 flywheel HP.
Your HP computed from your vehicle MPH is 320.34 rear wheel HP and 355.93 flywheel HP.
Did one that incorporates air temp, humidity, and elevation and it said I had 370+ HP LOL, I think it must mean at the fly wheel

OK, I'll stop, but these calculators are fun

O-Five is correct I dynoed 291Hp/324Tq then 295Hp/330Tq with in 2 weeks of each other on the same dyno same driver. Drop in K&N and FM 50 dual in single out

3rd Gear is not 1:1, but here is why we use it....
I believe our 4th gear is 1:1; or we would have to have a double overdrive transmission, we do not. 3rd gear is not 1:1, but we use it to avoid hitting the Speed Limiter while on a dyno. We can not do 4th on a dyno, unless the truck has been tuned and had the Speed Limiter increased. This simply became the accepted standard for Titans, years ago. OK, maybe 3 or 4 years ago.
OK, here is some info from "bestatchess", way back in 2005 in reference to the Titan and a 2004 F-150:
The rear axle ratio is higher (numerically lower) because the 1st gear of the five speed transmission is lower (numerically higher) than found in the competing 4 speeds.
To get the effective gearing, you have to multiple the transmission ratio x the transfer case ratio x the rear axle ratio.
For 1st gear, low range, for a 4 x 4 Big Tow or Off Road Titan, the calculation would be:
3.827 (1st gear) X 2.596 (low-range transfer case) x 3.357 (rear axle ratio) for a crawl ratio of : 33.35
For a 2004 F-150:
2.84 (1st gear) X 2.48 (low range transfer case) x 4.10 (rear axle ratio) for a crawl ratio of: 28.88
The F150 has a 4 speed:
1st 2.84:1
2nd 1.55:1
3rd 1.00:1
4th 0.70:1
Reverse 2.33:1
The Titan has a 5 speed:
1st 3.827
2nd 2.368
3rd 1.520
4th 1.000
5th 0.834
Reverse 2.613

Since you have read this far, go ahead and read this thread, for an early discussion of the Transmission, Rear, and Dynoing the Titan. Outstanding info:

I stand corrected on the 1:1, forgot about that, been a while since I had my Titan lol. I remember now long time ago the Hemi guys used to complain that the Titan's dyno numbers were higher cause the dyno runs had to be done in third which isn't a 1:1.
Regaurdless, the numbers you get aren't as improtant as a good a/f ratio throughout the rpm range. Dyno numbers very widely from one to the next.
