1st gen Records?

Each dyno will give diferent readings on the same day, same truck. May only be 1 or 2 hp, though. Throw in different atmospheric conditions, and it gets trickier to figure out who REALLY has the highest HP. Dave Dunbar has a mobile dyno that he pulls around to various events, so people from across the continent can have at least one constant variable in comparing hp/tq differneces between KY, CA, and BC.

Stomps truck is nice... for a beat up farm truck.

So what it comes down to is "yeah, that makes a lot of power" and "yeah, that makes a lot of power too".

A dynojet measures acceleration to determine HP using F=MA. A Dyno Dynamics or Mustang are load dynos that measure torque to calculate HP. In my experinece the dynojet reads a bit lower especially in torque than the other 2 styles because it has turbo lag included in the run. The advantage to a dynojet is there are no loading variables to give diffrent results, also it does a better job of showing driveability. Many people complain they can't spool on a dynojet to make power, while that may be true it also means its a lag pig that would get spanked on the street.

i think that a load type dyno has more of a chance of being accurate to street driving if set up correctly but since it is a variable than the results can be very inconsistant. The new heavy wheight dyno jet should be a real good dyno for these trucks with drums at 8000lbs instead of 6000. I've ran a dyno jet alot and I have a application into a shop that has a mustang so hopefully I can figure out a load value that will make the numbers comparable to a 248c.

That makes me feel better. I usually can get just as much boost on Dynojets as I can on the street. I do hear a lot of people complain about that also.
I've been on 2 dynojets a few times and I always get the highest numbers on them; 2 Superflows usually about 10 hp less; Ats's Mustang is not generous what so ever when the correction is off.

What is the highest 12 mm hp

[GLHS]

Sounds like you have or are going to dyno?
I hope you do well no matter what Bill says.
Kta has done 488 uncorrected diesel only. I think he had twins and head work but that was 4.5 years ago when we were all trying to make 300 hp. I think he did 480 with a single.
Jayers has done 501 with a helix 2 cam I believe. Don't know what he had for turbo(s). Someone correct me if I'm wrong.
I have done 472 uncorrected diesel only, single charger, stock long block at 2600' elevation.

[pulltilbroke]

thanks GLHS

But I thought Jayers was on a 14 mm



I'm shootin for 500 on a 12mm then

[GLHS]

I have a feeling your shooting for way more than 500.

You may be right about the 501 run with a 14mm head.

[pulltilbroke]

Yeah I guess I am shootin for well over 500 but I'll try to hit 500 with my current pump

[JAyers]

Yea guys it was a 14mm pump with a 62/71 S300.

[pulltilbroke]

KTA or Rockentech H&R?

I aint no dyno master but wouldnt difference in tire size also be a variable to consider. To be perfectly accurate, tires would be same size, gears would be the same ratio. Just a thought, if you guys are trying to compare apples to apples you got more like red apples and green apples. Same fruit but different in many characteristics.
