460hp with 550hp mods?

[DieselFreak92]

At a dyno event over the weekend my buddy dynoed his 6.0 and we were really disappointed in the numbers. He has Warren 190/100s, Barder Stage 3 turbo, Airdog, studs, intake, FICM tuning, NADP Trans, and custom tunes from Eric and only made 460hp. He is also on an 8 inch lift with 37s in a cclb... What is going on here? Bad tunes? With 175/75s and some industrial injection hybrid turbo he made 475. When we talked to Innovative guys at another dyno event they said he had a 600hp combo..

Fuel pressure?

 

[B.Warning]

I'd at a combination of a ****ty dyno and large tires. My 6.4 was a 650hp +- truck and it only dyno'd 430hp on 3 runs one time. It was a cclb on 36x15.50 w/ 20x12 wheels. I wouldn't get to caught up on a dyno number if the truck is running out good.

Weigh it, then take it to the track and see what it does.

Well my other buddy with his 6.4 dynoed 546hp at this dyno on the same exact setup as he made 540hp on at another dyno. Fuel pressure I have no idea. Towing an empty 20ft enclosed trailer to the event he was running 1300* on the highway in his tow tune. He claims bad tuning but I know there is more to it.

It's a dyno... Some trucks don't dyno well, some dynos lie...

 

[Mdub707]

Exactly, it's a dyno. I wouldn't take it to heart too much. I did 466 rwhp on a dyno with a stock truck and X-race loaded up... See my sig? LOL

Obviously the huge tires aren't helping things. Take it to the track and see what it does. If it puts up similar numbers, then you can start to worry.

what was the weather like?

I dyno'ed 654 at TS last year after going 12.05 @ 113, and 11.99 @ 111. My truck should have been 800+. Dyno's lie track times will tell.

Thats the fastest 650 I've ever seen.

Always on point Danny.

I know the guy in our local group that owns the portable dyno has a hell of a time with 6.0s not stayimg in the right gear to make a pull.

With that combo you should definitely be 550-600hp.

There are way too many factors to be able to just jump on here and guess what is wrong without a little more info. It could have been one of many many many different things. Im sure tires are not helping things but 100hp low is more than just tires.

I personally have great luck with dyno's. But I go to a dyno that I trust, they know how to run the dyno, and no one is trying to cheat the numbers. I can get within 10-15hp every run with the same setup on the same truck. I have even run them months apart after putting on a mod that lost power and then switching back to a previous combo and still got with 10hp. I use the dyno to test difference when developing our products... not so much to prove how much power the truck makes.... with that said every dyno and every dyno operator differ so that could have been your problem... but I would not just jump straight to that conclusion.

Track numbers can also vary depending on temp, elevation, tires, lift, launch etc...


IMO the easiest way to check to see if it is the dyno... or the truck... is if you give us a little more info. With 190/100s and a stage 3 turbo you should be able to check the parameters of your truck to see if any of them are out of whack...

egts?
boost?
Fuel pressure?
ICPv?


How does the truck feel?
Was it locked in OD for the dyno run?
Is it super smokey or super clean on WOT run?

For example... if you are hitting 40+psi boost, 1700egts, 3.9+ ICPv, and 50+ fuel pressure psi... then I would say it was the dyno. But I would not just jump straight to that conclusion right away. It could be weak fuel pump, weak hpop, boost leak, exhaust leak, bad tuning, etc...


Hope that helps

You are probably right... checking your trucks vitals to make sure nothing else is wrong before heading to the track would be crazy LOL

Ignorance is bliss lol I definitely agree on egt, fp and hpo. If all that's good I'd say it's the dyno. Even if it's not I'd still blame it on the dyno

Who was it?

His name is Nick De Lecruzia from southeast PA. He got the turbo through Josh at DirtyDiesels.

His EGTs hit 1800 on the dyno. Smoke wasn't insane, cleaned up pretty good. The rest I am sorry I don't know. He is going to get some new tunes and see if it changes.

Or just take it to the track lol

I think that's our next move. Maybe an open track night soon.

Yup. Even with a bad launch or ET, your trap speed isn't going to vary much at all. Your trap speed and an accurate weight will tell you what's getting to the ground.

Exactly

 

[KCTurbos]

Tracks can be off just like dyno's. There are a lot more variables going on than most guys care to give credit for.

All of these will affect and change Et and/or trap speed (not always both)...

Altitude
Tire height
temperature
humidity
wheel spin
shifting (even with a lazy auto)
track prep
wind gusts
reaction time
60ft
lift kits (aerodynamics)

I have seen people pick up a few mph with changes that had nothing to do with the hp of the vehicle. That can mean a "50hp" difference just with a few mph when in fact the hp did not change at all. I am not bashing on the track... but it seems that some people think that it is an end all win all perfect system... :badidea:


Dyno's and Track can both be used in positive ways... but they can both be misleading
