April 11, 2006Ya gotta love butt dyno's. Too bad they are worthless. Do a baseline on a real dyno. Add your mod/mods and go back to the same dyno and same operator and see what you got. That's concrete evidence and not, "I feel a difference."

April 11, 2006wow, all these reply's are good...but for some of them, I feel like Tom Cruise did in days of thunder....he was talking to Robert Duval...."I don't understand a stinking thing you're saying!!!"....(paraphrased)...hehehe... but I'll get it..I have my friend how is a big help to me with this..but this is good stuff too..
April 12, 2006"My wife thinks I'm going through mid-life...maybe I am...I'm 45 this Thursday..and I've not had this mod bug much before...but now I want it....heheheh "
Know whatcha mean. I never bought "doo-dads" for my cars before, but this just seems to call out to me...
Wife tolerates me, but has declared "no flames"...
April 12, 2006MID LIFE? You plan on livin till 90? Too long for me. I figure I just passed midlife last year at 40.
I know about the butt dyno. It's all relative. In my case there were times i really didn't expect to feel a diff, and did, and vice versa.
But so far no one is willing to spend the cash for a real dyno.
And if the donut is bigger on the GT then why bother taking it out, unless it can be made bigger yet. Taking it out (And i'll bet you a case of your favorite beer on this) will only create unwanted turbulance and reduce the power. Factory put it there for a reason. I've talked with an engineer on this very issue (an engineer that deals with air flow on a daily basis)
Either way if your looking for performance, make sure whatever you get keeps the intake air cool. Make sure your not drawing in hot air.
April 12, 2006You are right Tom. the PT will do better drawing in cool air an not hot air,
April 12, 2006Well I don't know if I'll live to be 90...but let's say I've gotten some toys this year....
I got the Mopar cat-back duels from the place today..I got it for $100 less at my father-in-laws price..... I'm hoping we can get them on on Sat...we'll see...
As far as the cold intake...does Phoenix summer provide enough cold air? hehehe...
I'm either going with the blowoff valve or the dual air...my friend also tells me to get the down pipe for more HP from the engine....but all in time I tell him....still gotta pay for the car... I'll try to get some picts of the install (before, during and after)...and post them.... video too....
Anway, take it easy..
April 13, 2006Saw this..
Here's a steal on an intake -
(He's a good guy, too)
April 13, 2006Ok, I just saw the birthday thing...that's kind of cool....Nothing like letting the world know eh?....ahahaha Well I guess the new car and the cat-back exhaust is a good present eh?...
April 13, 2006QuicksilverDon,
I tried to get to that site and it took me to a registration page.... I'm always a bit hesitant to sign up for things...maybe mostly cause it's just another user name and password I have to remember...and at my age, that tough enough.....my brain gets mushy after a while.....hehehe

Obviously, you are not into producing big hp in the PT turbo. Those of us who are serious about it remove all three silencers, the two in the airbox (one of which is the doughnut) and replacing the turbo to airbox hose because the factory hose has the third silencer. Along with a K&N drop in air filter airflow is increased big time. What goes in must go out so you change your exhaust to a 2 1/2 - 3" free flow one. Along with other power mods my '03 GT was running 270+ hp. Others are running over 300+ hp. The three silencers were put there to quiet down the intake and turbo whine. Once the three silencers were removed my GT sounded like a small jet taking off.....Oh yeah, my favorite beer is Heineken.
April 14, 2006I'm talking about just one of the silencers, the doughnut. It is a venturi which will smooth out the flow, without it the sharp edges on the air box will cause a lot of turbulance. If you take that silencer and make it the same size as the tube leaving the air box, then your making a true difference.
Is there any difference other than size that I'm not aware of on the silencer or air box on the turbo VS. the N/A
The only way that it will help for you taking it out altogether is if it is significantly smaller than the hole it goes into.
I'll keep the beer cold in my fridge for you. come on over and pick it up.
But seriously speaking, the only way to prove this issue is on a real dyno, not the butt dyno as you like to put it. Try it with and with and without that doughnut, post the results, and you'll get your case of beer
And while we're on the subject of intakes, I have posed the question to you a few times about which brand of throttle body spacer gave you 3 mpg. I'm still waiting on an answer.
April 14, 2006Like it was said the doughnut in the GT is bigger because the hose is 3". I don't have the GT anymore. A lady in Cali bought it and races it at the track. My SRT-4 does not have a doughnut in the airbox, in fact no silencers at all in the airbox or the airbox to turbo hose. With my K&N drop in filter in the airbox (actually a cone filter, unlike the flat one the PT gets) and no filters I hear the turbo whine very well. DCX put in the three silencers on the GT because of the age group that purchases the GT. Older folks who don't want to hear a lot of noise and who want more power than the n/a PT. The SRT-4 is aimed at a younger age group that wants to hear noise, hence, no silencers. So I feel the doughnut has no relevance to airflow. It just quiets down the woosh sound you will hear without it. The other silencer in the GT airbox also quiets the air woosh. The silencer in the airbox to turbo hose quiets the turbo whine.
The TB spacer was an Airade. Lots of people will say it is worthless but as I stated previously my '01 PT got 3 mpg better with it on. If I hadn't been keeping records of every fill up since I bought the PT new I wouldn't have believed it either. There was absolutely no gain in power.
