DYNO PROVEN (BY US) MODS...The Numbers..

[Vee]

As a Fairly New owner of an essentially stock CTS-V I thought a thread like this might help Verify or Dismiss the claims of added HP from the various "Go-Fast-Parts" manufacturers...

What I'm hoping to get started here is a thread about ACTUAL gains as witnessed personally by YOU so that we can help each other in the Mod descision making process.

Of Course a lot of us are at different stages of "Modding" and a certain part may be more beneficial to one car than to another, so when making mention of your new mod please remember to list other current (pre-existing) mods. (Remember that relying on your "signature" for that list of mods will eventially become misleading since your signature will change as you update your list of mods, but the original coments based on your "set-up" at that time will not)

Posting comments that you "really noticed a seat-of-pants difference" are helpful, but Posting that your car "Dyno'd at 3XX hp before this one mod, and now it Dyno's at 4XX hp" are EXACTLY what I'm hoping for here.

Here Is A FICTICIOS Example...
____________
"Doc Brown's V" posts:

My "V" dynoed at 367 rwhp with a K&N CAI and Magnaflow Cat-Back. After adding a Flux-Capacitor the rwhp increased to 1367. A Flux-Capacitor added 1000 rwhp for me !! Yay !!

I'm sure some of you have well documented numbers.

PS: Be sure to mention what kind of Dyno Machine too, as I hear they measure differently.

Who's Gonna Start?

Yes, But it would be a lot nicer to search one thread knowing the specific information may be inside than to search an entire forum part-by-part, sifting through a plethera (cool...I got to use that word) of threads that are often dead ends.

For example, I just did a search to try and find out the HP gains of the Magnaflow Cat Back. I used 3 different keywords in 3 different searches, looked through a few promising looking threads, but found nothing. In fact, this happens a lot. Think of this as a discussion of "What Mods Will Actually Give Me More HP, and How Much?"

I'm not trying to reformat the forum, I am just looking for some no-nonsense, no BS, facts about HP Gains for various Mods.

Let's face it...We all want HP !

Headers, Heads, Intake, Throttle body, no cats/FF cats, Supercharger, open exhaust, and a PCM tune to match any and all. That's where you will gain more HP. The more you do, the more you gain. Also a lightweight flywheel doesn't hurt. Plus there's always the juice.

I thought that only worked on Hondas

Ok, I'm a little afraid of The Juice, but if I just put a NOS sticker on my car how much HP will that give me? Now we're getting somewhere. What if I do full billboards down each side?

Suggest purchasing the brand of cat-back exhaust that gives the sound you're after, not X frees up 3 more hp than Y.

The brand you're interested in has sound clips and a dyno sheet on their website.
