Dyno run with mods

Those are above average I would say.

You should try to cut back on your sig pic though :dontknow:

Are these good numbers for the mods I have? Is my truck running to rich? The VEC3 is my next mod, would that help lean it out, how much HP would I gain?
Even though it says max power 464.9, what is the 480.9 next to it?

Well, those a decent numbers but STD are typically a little higher than SAE.

Yes, the truck is a little on the rich side. A VEC3 would allow you to add a some timing and give you a nice flat A/F ratio wherever you want it. Typically 12.8-13.0 is a good range for HP but safe enough to not worry about running too lean.


That 480 might be the ft lbs at peak HP :dontknow:
 
Whats the diff between STD and SAE? My SAE was 451.2hp and 471.8 touque

Internet is a beautiful thing ;)

SAE -- ...SAE J1349 standard of June 1990. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque. Friction torque can be determined by measurements on special motoring dynamometers (which is only practical in research environments) or can be estimated. When estimates must be used, the SAE standard uses a default Mechanical Efficiency (ME) value of 85%. This is approximately correct at peak torque but not at other engine operating speeds. Some dynamometer systems use the SAE correction factor for atmospheric conditions but do not take mechanical efficiency into consideration at all (i.e. they assume a ME of 100%).

STP -- The STP (also called STD) standard is another power correction standard determined by the SAE. This standard has been stable for a long time and is widely used in the performance industry. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard. Once again, this means the STP corrected power displayed by your ... test system will be more accurate than power numbers obtained using a default Mechanical Efficiency of 100% or 85%.
 
The a/f isnt really all that bad. The VEC will help some but with your current a/f being pretty reasonable you wont get much more.
 
Very much so. I dont know how much nitrous you can run safely on the stock pistons. Others will chime in on that. Who will be doing your tuning? Its all in the tune!!!
 
Ill have to do some shoping around for that, there has to be a good tuner in south floirda some where. Would I be over 500 hp with the VEC? Is it worth the $1100?
 
the newest Vec III version is well worth it , I am thouroly impressed with it.

But no, you will not acheive 500hp with jsut the vec, probably looking at your run around 15hp area plus or minus 10.

Remove your cats is another 20hp.

then hit on about a 100hp shot, and read this next sentence carefully:D

with a tune on the vec III jsut for the NOS.

with the Vec you can have 1 card or 10 cards each with a different tune.

the vec is expensive , but the best easiest way to tune on the dyno.

The 480.9 is your torque at 4500 Rpms. If you look you can also see your AF ratio (11.5) at the bottom too for 4500. Also 411.4 HP for 4500.
