He didnt say 500 he said 552. Either way though If their are really 550HP trucks on stock turbos(dodges) show me one runing some good 12's. Dynos lie, the track doesnt.

No actaully you said 515hp wasnt possible and Im saying that it is very possible.

Did you see the either way part of my post by any chance? Like I said show me one of those trucks with a stock turbo runing 550 or 515 horsepower passes at the track.

My truck doesnt have 500hp but if I could get it to hook up in the 1/4mi I would be close to the high 12s.

Well its a 6speed so no 12sec runs, but I dont know what to tell you b/c it was at Commerce Ga for the Hayes Diesel Drags, it was Dunbars dyno (and all Dunbar does is go around the counrty w/ his dyno to dnyo people) and there where quite a few people ****** b/c of their low HP #'s.

I guess I got lucky or something and tricked the dyno or something.

Also I know one other guy in a 05 that made 555 hp on his stock turbo. That was Robert w/ NGM Diesel

Theirs no room for if's in drag racing, if it doesnt it simply doesnt.

In a perfect world track times will equate with horsepower. However not all trucks/cars etc. are setup for drag racing so to equate track times with horsepower is only somewhat of an accurate measure and does not tell the whole story.
It is a reference point and tool but that's about it.

My truck is right at or under 700rwhp on a chassis dynojet. I bet I could not click off a 14 in the quarter mile if my life depended on it. Does this mean the dyno is lying to me as well?

Oh yeah, I remember a 12 valve with a stock tranny and HX35 that squeezed off a 12.9 several years back.

On another note:
I remember the days when several of the prominent diesel guru's in the industry swore up and down that 1000 hp out of 5.9 was not possible and could not happen. Also many of the west coast guys agreed with this and now 1000hp is for a street truck.
The same trucks that were 1000hp back then are now 2000hp+/- on an engine dyno.

A couple things to check on that Superflow. The first and foremost is the calibration of the load sensor (torque cell). The second is the RPM measurement and why he could only show you numbers from 2900 and up. The third is the tire slippage. The fourth is the correction factor used. He actually said he corrected it to Dynojet numbers? Holy smokes that insane. It either reads correctly or not. Model 248 Dynojets use pure inertia so they read consistent, no load sensors. The only way you can make them inconsistent is try to cheat the atmospheric conditions measurement or cut a piece of the steel drums out with a torch, that's it. Put it on a Dynojet and then repost your numbers so we can see what's going on. It seems low to me.

I talked with the machine shop that has the dyno. They said the calibration is good, he said they read the rpm's so it would not down shift???. As far as the correction factors, Superflow programed it so the numbers would be closer to Dynojet numbers rather then Superflow numbers, so that was a Superflow thing not the operators correction. The other correction was the atmospheric conditions that the computer makes using the weather station. He said all the setting have stayed the same since the dyno in April.

SO if the April numbers were correct, what is the problem with my setup?

The point is that just becuase a truck dynos a certain number does not mean that its going to run a certain number on the track.
