Dyno, For all you...yeah Options

[snadman]

For all of you people who STILL feel that exhaust, plugs, and intake will add amazing ammounts of horsepower...I'm going to a dyno on the 28th of June. I will make sure to find this thread and post the graphs so you can see my car isn't a supercar with just those mods. I'm just getting kinda sick of people saying their intake's going to add 15HP, because it's not. I'm sick of people saying that exhaust adds 15HP, cuz it doesn't. AND I'm sick of people saying that plugs make so much more of a difference...

-For the intake, I may see a few HP, nothing big though or noticeable.
-Exhaust same as intake...you're actually just freeing up HP you already had with better flow (learned the exact details from Exhaust 101 in Import Tuner)
-Plugs...may add something, but not much. I've seen it where plugs don't do anything, but I've also seen minimal HP increases. I'm guessing it won't be anything and basically upgrading to expensive plugs on an NA Celica isn't going to help much.

**PLEASE don't take my whole plugs rant seriously if you run nitrous or turbo. You guys need good plugs, cold plugs! This is for NA Celica's only!

Haha sorry man Im blind but hey I just found this killer site with a 700hp Turbo BMW M3 which also gives a great explanation of exactly why exhaust and headers reduce back pressure which we know but I never really knew exactly what the back pressure was, its not really just the exhaust being held back like I used to think. I thought someone might be interested. http://www.da-motorsport.com/teknik/makale.../makale3_en.htm
