By that you mean you want more power? Sure - Stage one Computer $500 - 5hp&30ftlb. intake about $160 to $250 7-12hp& 7-12ftlb. MSD Wires $50 - 0-1 Hp just runs better. that is a good start.

Forget the intake. I've never seen more than 2-3 hp gain and a LOSS of torque on the dyno. Seriuos gearheads go with removing the two silencers in the airbox, using a K&N drop in filter and replacing the turbo to airbox hose.

My 2004 PT-Cruiser Turbo with a K&N Typhoon air filter on the dyno made 11hp. 7ft.lbs of torque. Your right tho when you say that they lose out on torque... on a normaly asp. engine. On a turbo they will produce quite a bit of hp if the turbo has an intercooler. Cooler air.. more hp. Quicker boost up... more torque.

Actually, I see it in reverse with the turbo being more affected. Every dyno I've seen with an open intake was a 2-3 hp gain and a bunch of torque lost. Like this:
http://ptenthusiasts.org/...87-dyno-results.html
19 lbs/ft is a lot of torque to lose. It will cost you off of the line. I wish it was that easy to get 11 more hp, but I think you'd better go slap your dyno operator in the head and tell him to do it right. So what was your base dyno numbers and then the numbers with the intake? What are your power mods?

I called up my dyno guy and he had told me that most people when doing a dyno pull, make the pull on the dyno in open air with no fan or anything blowing at the front of the car. Yes the engine compartment will be filled with heat from the engine but with the fan simulating the air entering when your driving cool air enters and gives you more. He tried it. Also i would like to know what they mean my open air filter. Are they just talking about taking out the filter from the box cause that won't do anything. Most people call it a cool air or cold air intake. At the track i was running a 15.8 in the 1/4 not i'm running a 15.6 in the 1/4 and the only mod i have is the intake and wires. For now that is... so if it hurts when you do it.. why am i getting better times at the track. I might be doing something wrong but could he also be doing something wrong... because right now.. it don't make any sence.

I found my chart.... It shows as follows.
Max hp STOCK: 168.5@4975rpm
Max hp w/Wires & Cool Air Intake (typhoon k&n) 178.9hp@4750rpm
Max hp comes in sooner @4750rpm with a 10.4hp gain.
@4200rpm were the rpm's drop when i shift have a 10.9hp gain.
hp@4200rpm= 140.6 stock
hp@4200rpm= 151.5 with wires and cool air
I'm not too sure on the torque because i can't seem to find my torque curve chart. My filing system sucks.. haha.
I was talking to a dyno guy just the other day on the subject and he was telling me that some mods will affect other mods. He gave me an example. One of his customers have two 2008 mustangs. There both identical with options and all the only difference is his is his and her's is her's. What he ended up doing was getting an exhaust for her's and one for his.. both from flowmaster. He wanted to be better so on his without his wife knowing got a hi-flow cat installed on his. After the dyno runs it showed that hers made 4 more horse then his even tho his had a hi-cat installed. The only thing he could think of at the time was that the high flow cats hurt the back pressure making the o2 sensors read different making it run richer and giving it less performance.
The artical that i have read showed that he also has a bunch of other stuff done like the stage one kit, blow of valve, ect. Some mods will hurt others. Also depending on the way you do your runs it may affect it. Doing the first pull cool second hot.. then going back and doing the change and running it again cool could give you a good reading. Many factors can give you different readings too. All in all, what i am trying to say is that stock.. my car had gained from the cold air intake. I also see it at the track. You may be right.. i'm just going from what i have.

My bottom line is you will get better performance with a K&N drop in filter and stock enclosed system with all three silencers removed than with an open intake (open intake not blocked off from hot engine air). The main consensous on the SRT forums is the stock enclosed intake system with a K&N drop infilter is best with the stock turbo. Going big turbo you need a larger open intake for more air flow. One of the good things you did by going with an open intake was to get rid of the three silencers in the PT turbo stock intake system, especially the silencer in the turbo to airbox hose. That silencer narrows down from 3" to 1 1/2". Talk about restricted airflow. Again, I ask this question, why do factory cars come with enclosed intake systems?

To make the car quiet so the moron on his or her cell phone can hear. Not drive like they are supposed to do.
