here ya are. a little dissapaointed, but that is why i wanna run it, to get it dialed in.

MODS:

E-fan
Apten
4#
JLP intake
Plasma Booster
SBTB
90mm MAF
3.55 Gears

all i can think of this second.

 

It's hard to tell with no numbers displayed, but it looks to be about 375ish on the power and maybe 440ish on the torque. If so, you are really not THAT far off what you should be with those mods. Don't forget, your truck started around 320 rwhp, NOT 350rwhp like the 01-up trucks. So you can't really compare your numbers to all the people with newer trucks that are posting the same mods. But let us know the actual numbers.

 

No chip or reflash

 

C'mon Jim, you no better than that. lol. Yes, chip.


Sal -
Thanks for chiming in. Couple of responses to your comments. With the IC recall and the 90mm intake shouldn't I have made up most of the HP difference in years? And if so, wouldn't it be fair do make cross year comparisons? I realize I am still running 3.55s, but still.

Oh, just remembered that run was on 20s also, so I am sure i am taking a hit for them.

The numbers were:

385.66 HP@4948
454.50 TQ@3841

I mean to send to files to you with my chip and give her another go, unless you just dont think there is anything in there. I honestly do not know where my timing and all that is at Sal. My program name is KB1A that that was run on. If you get a sec could you take a peek and see what my settings are at and let me know your thoughts?

Where should I go from here?

The recall has nothing to do with power. The power difference from 99/00 to 01-up is in the design of the lower intake manifold. The 99/00 is just a huge open chamber right to the heads. The 01-up style has about 3 inches of runner between the ports to increase velocity and straighten the airpath to the intake ports.

Your A/F looks fine to me. If you dynoed on a street tune, then you should have 16 degrees of timing, and I wouldn't want to add more.

 

Thanks for your input Sal.

Anyone have suggestions for the next step? I have some ideas, but I am open to suggestions.

-Kimball

 

Where are you dynoing at? Is there high elevation involved?

 

Kimball,

I didn't know what you were running as of late. You should DEFINITELY be 400/500 with your mods. It's all in the tune baby

Good luck!

 

Dynojet Research
Belgrade, Montana
Elev. 4454 ft

pretty sure that the elevation is considered with the correction, thus the correction factor of 18%. real numbers were down around 310HP.

Jim -

I understand the all in the tune thing, but according to Sal the tune is where it should be based on the AF and whatnot. Although I wasn't expecting much higher numbers on these initial pulls, I did figure that 400/500 would be no problem with some tweaks.

If any different views, or aspects of the run would be helpful to anyone, just let me know as I have the files and the viewer handy.

Also, is there a 'proper' way to run these trucks on the dyno? The engineers at Dynojet and I had different views on that subject. These numbers were from the 5th run i did, but I do feel I gave her good cool down prior. The numbers did keep going up though.

Any pointers on starting and when to stop would be helpful.

Also, any takes on where I go from here will be entertained.

-Kimball

 

I just noticed the temp for the run. Sure didnt feel like 83.42 degrees........

Kimball,
I just dynoed my '00 last saturday too. My numbers are similar to yours. 388rwhp/486rwtq... a little on the rich side on my race tune... The lowest numbers are fron April, different tune on the chip....


here's my mods:

DiabloSport Delta chip
interchangeable 2.77 and 2.84 upper pulley set
JL Ram Air
JL 5# pulley
JL Thunderpipe
FRPP 90mm MAF
Accufab TB
NGK TR6's
Mobil 1 10w/30
Oil separator
Boost by-pass mod
170 deg. thermostat
Flex-a-Lite 270 e-fan
Cobra water pump
Factory Tech valve body
deep trans pan and filter


JR....................

 

Put her in D with OD off and take it up to 68-70 mph (might be different for 3.55 gears) and punch it.

I dynoed at WFC inside an 80+ degree trailer + 100% humidity with no air movement. No cool down time, hood down with an open air (Hot air) kit and hit 417/509 with basically the same mods as you. I figure the less than ideal conditions are good for about 10 more hp. Since the 99/00 trucks dyno a little lower, you should have been just over the 400/500 mark, but definitely should be there. My A/F is a perfect 11.8 btw. There is definitely more in your tune depending on timing and A/F up to 12.0.

What was the correction factor for the dyno? If it was over 1.0 that day, you had crappy conditions. A good weather dyno typically has a correction factor of 0.98-0.99.

Your A/F is also opposite of every other dyno I have seen. They usually start out lean (around 14) then drop quickly and level off at high RPMS. Yours seems to start out really rich then rise? How did they dyno you exactly?

 

I had a correction factor of 1.18, but problem is with my altitude it will always be *****ty.

That particular run was from a 65-70 mph roll with OD off. Let off the pedal around 5200-5300.

It was downshifting on me doing it this way. Not sure if it supposed to or not, but It kept doing it.

-Kimball

 

here is a pic of the FULL run, not just the last gear.



i just looked again and there is a spot after the downshift where it hit 392HP.

-Kimball

 

I am confused looking at my dyno sheet vs yours now. Mine was taken to 70 in D and nailed and did not downshift. My rpm's were at 3,200 at the start of the pull. Yours are higher rpms than mine and you have 3.55's vs. my 3.73's. You should be at a lower rpm than me at the same speed, not higher
