Dyno?

[tones2SS]

Okay,..........I gotta ask.
Has anyone had their truck dyno'ed before and after modifications?
I hear of people saying that the mods they used had passed the "butt dyno", but that can all be psychological in my opinion. I'm looking for hard facts/numbers before dropping any money into mods, such as FULL exhaust, cai, and others, just to make it sound meaner. I want it to sound mean, but run mean too. Not just throw good money away.
Thanks!

The problem with this is the cost of going on a dyno that many times. Dynos aren't cheap to use...

Tuner > Headers > Torque Converter > Gearing

Move on from there. Intake, full exhaust, PTB. You can switch up anything after the tuner with the 3 above as well. They are all signifigant gains.

Depends on how you do it.
I wouldn't do piece by piece. (I'd do once and done. In my opinion, that's the way to go.) Granted some people don't have that luxury, but, you gotta sacrifice to get what you want sometimes. I am.

So, how much gain did you see? Got any photos of the dyno graph?
Also, list your mods from the company you bought them from. I.E., Stainless Works, Borla, JBA, etc.
Thanks.

I was taking it as the OP wanted to dyno before and after each individual mod, which would be expensive. One time on the dyno just to see wouldn't be too bad but after every new thing it is.

Have no dynos. Dont mod because mods wont help you without dyno proof. Mods are in my sig, pretty obvious.

You must be a troll.

Exactly troll.
You just made my point.

 

[tones2SS]

I'm sure some of the vendors here will post up some links to Youtube or some similar app showing gains in HP and TQ from before and after mods.

I think 0-60 times are an ok indicator of a gain. Not as good as dyno obviously but surely u can see the gain.

I will agree with that.

Why would you call him a troll? He just asked a reasonable question. I haven't modded my truck with any engine enhancements, but if I decided to do so would be great to see some actually evidence what works and what doesn't, be that via dyno numbers or 0 to 60 or 1/4 mile mile times. Being told it feels faster by the "seat of my pants" doesn't provide what the OP was trying to find out.

Thank you sir. I appreciate it.

My point of this thread;
Why would anyone spend money certain mods if they don't actually give you any gains in performance? I wouldn't mind dropping a grand or so for a CAI, full exhaust with tune, and some other little goodies if I know it's going to give me that performance edge.

 

[PostalTwo]

Preformance increases thru upgrades are highly documented u just got to search them out. Intake manufacturer like vararam actually guarantee that u will see the difference in your 1/4 mile times. Tuners like the trinity have 0-60 timers so u can measure the difference.

ARH has posted dyno graphs of their headers w/ gains. A tuner will also increase gains, increase drive-ability, and allow you to tune for future.

Gears and tq converter are no brainer mods that obviously increase how the power is put down and there is nothing really to document.

Vararam has dyno graphs showing their gains.

If you are looking for an average joe driving our truck daily like most of us do to perform dyno results before and after of each mod, good luck. It most likely will not happen. As previously stated, the cost and time involved is more than most want to deal with.

Long tube headers on any v8 engine for the last 60+ years have produced gains over stock manifolds, no matter the application/vehicle. Tuning obviously unlocks much more than is available, hence the reason why anyone looking to increase their performance go with this first. Torque converters allow the powerband to be "shifted" due to a later stall speed. This is pretty much a no brainer to increase off the line performance. Gears will allow you to get the vehicle moving much quicker, and get you into the powerband quicker. Again, a no brainer.

Yes I called you a troll as everything I stated above has already been provided in a dyno by the manufacturers or the common sense is there for it. You seem to be the hard headed type who wants more information than what the manufacturer and common sense has to offer and do not believe it.

If you noticed, I did not state an intake as one of the first 4 major mods as I do not believe there is enough there to warrant the cost and if you are looking for performance, theres much more elsewhere. Just as I did not recommend a PTB over headers like some people like to do. No, I do not have a dyno to back up my claims as headers being a better boost in power but its the truth. So take it however you want.

Yea, I've found myself using other forums due to people's attitudes here. I've watched people get jumped on from a few in-particular around here for asking simple harmless questions. They talk all they want behind a keyboard and know there's no repercussions. Isn't the reason why we come to a forum to gain knowledge that we lack but strive to know? Yet some of the people that do know are bored of talking about it, so they get upset when others ask, or some don't understand what the others are saying and are badgered for asking more questions to try to "get it". It's sad. I fight for my country and come home to this kind of crap and it breaks my heart. I'd like to think that I'm fighting for something a little better than this. I'm sorry, maybe I'm wrong.

Most everything you just wrote here, I pretty much already knew. It's not just putting out power and torque, it's about putting it down as well.
Maybe because I'm on the Mustang and Challenger forums a lot and those cars with mods more times than not, have dyno RWHP and RWTQ numbers. (I have a supercharged Mustang in the garage putting out 565 HP and 505 lbs. TQ. I've thought about a smaller pulley along with a 93 octane tune in the past. )
I would LOVE long tube headers, but in MA, we have STRICT emissions laws, so shorties would be the way to go. I'm not asking about a dyno after every mod, that is just dumb and very expensive as you stated. Never did ask that. Not sure where you got that from? I probably wouldn't swap out gears as I have the 3.92. Although, I know there is a higher gear.
I appreciate your reply and trying to answer my questions. Thanks!

Maybe you should ask if anyone has dynoed their rig after the certain mods you were thinking about. You left it vague. I just added a vararam,87mm PTB, and a trinity tuner yesterday. I know i can feel the power gain but I dont know what it added as far as actual hp and tq

With all due respect, you should reflect within with regard to who is being "hard headed". Yes, manufacturers will make claims as to how well their product does, anyone that has done mods on their vehicles have found certain claims are more hype then true. It's not that they are dishonest, its more like they have optimized their tests to skew in their favor. In business that's called puffery.

A lot of guys here have run their own 0 to 60 times and others actually go to their local track for 1/8 or 1/4 drags. This is the information that is very helpful for people on this forum looking to spend their funds on mods.

I fully agree that expecting the layperson to do dyno tests pre and post mods is not going to happen. Don't be a hater because someone asks a reasonable question.

 

[doz]

A reasonable question is one thing. Being flat ignorant is another. Now the guy is stating that he cannot use long tubes due to emissions. Long tubes are one of THE best mods for our truck that any joe shmoe can do with minimal tools, jack, and jack stands.

I know that manufacturers do not always make accurate claims, but some do. There have been MANY people who have gone through the same thing this guy is asking. The only difference is this guy is asking for before and after dyno runs of each mod.

Im sorry if some of you feel that I am being a **** about the situation, but come on lets be reasonable. Everyone is here to help and offer up their opinions on products as I did in my first post in this thread. The OP then wants unreasonable demands and then makes excuses why he cannot run long tubes. Really? Take a peek under your truck and you will understand in 2 seconds why shorties on the stock system are not much of a gain compared to long tubes. Dont ask for before and after dyno (which BTW, there are before and after dynos floating around of ARH long tubes and ARH claims are pretty accurate of the users dyno numbers) when you are obviously limited to a half-assed solution.
