Default acceleration issue

Hi ive now had my 05 pt gt turbo ho for about 12 months now a have put around 4000 milea on it from 58k to 62k. I love the car it is bone stock besides k&n air filter and mopar bov conversion plate. I dont want to do to many performance mods because I dont plan on racing it as I want to baby the car. I want to keep the motor in good shape so I can drive it as long as possible with not problems. However the acceleration seems to be lacking something it has a 9 sec 0-60 time. Anyone know of any good mods to help improve this I dont mind bolt on mods but cant get into the motor due to this being a daily driver.

I've moved you over to the Turbo Performance section of the forum. It's Sunday morning and a little slow right now but hopefully later you'll be given a couple ideas (like Stage 1 upgrade and the newer composite intake) to help you out. Are you running stick or automatic?

Cool Re: acceleration issue

So, you've had the GT for abut 12 months now.......at 52-68K.
What do you know about the previous service record.....like when where the plugs and wires last replaced??? That the first thing that I did myself when I picked up the 2005 GT vert last fall!
Chrysler put crappy wires in the PT.
Have you pulled the plugs to inspect them?
Have you had the fuel injectors professionally cleaned??
Just some simple thoughts here.

As.....my 2006 GT gives me all the accel and fun I need!

Car was bought wrecked but the previous owner kept it in immaculate shape as far as maintenance and care goes. Since I have owned it oil was changed new map sensor new k&n cold air intake new plugs and wires top of the line performance wires all maintenance was done after being rebuilt and I added the mopar bov conversion. Im the second owner

Boost leak test it. I have a feeling the car has never had a boost leak test done to it, nor has the majority of the users on this site have done a boost leak test on their turbo PT Cruisers. Vehicle will lack power with a boost leak.

Also, how is that intake routed? You call it a "cold air intake" yet it is not a true cold air intake but a short ram intake.

I would bet you $100 flat out cold that the majority of the Turbo owners on here HAVE done a boost leak test and also that they have done about every other diagnostics on their PT that is available.

I have a customer base of 19 PT Cruisers of which 7 are Turbo models not one has ever done a intake integrity or boost leak test. I have at least a dozen or so members on this site alone that I help on a regular basis and NONE of them has ever done a boost leak test on their Turbo model PT Cruisers. Many when they(if) read your response will also respond in like to this.

where did you ever think of saying that many have done diagnostic testing when very few even have a diagnostic scanning tool. Look how many continue to post DTC information from using the "key dance"!

I know on all 3 main PT forums only perhaps a bakers dozen that even know how to properly do spark plug burn evaluations.


Most member do not even have a simple hand held thermal gun to do temperature reading and yet many members still think they have a cooling problem because when they left the hood the engine "feels" hot.

Which members have a battery load tester to check the true condition of thier battery.

Dude I could go on all night with this!

Better idea........
I will send you my Paypal address for the 100

IMHO You should ascertain the mechanical condition of the engine.

Compression check.

Than inspect the Turbo Charger compressor wheel for excessive movement or oil film.

Than move on to the normal stuff i.e. spark plug,ignition wires, etc.

You really need a vacuum/boost gauge to see what you maximum boost level is as well how the low rpm idle vacuum is.

Common sense things before you start increasing the engine output.
