My srt has hit 100k,and for the past few months the car can only muster 12.9@108 or a 13.1@107 ,I use to bust low 12s @113-115.I ordered new o2 sensors an intake manifold gaskets as a start also I had 4 degrees of timing pulled for nitrous.G ot to get my fuel trims checked I think the sl55 pump it too much for a code 3 pulley

 

Have you tried a TB reset? Don't even know if the SRT's have a TB reset but I do one on my N/A about every two to three months (except lately as I have an issue with the D/S steering wheel airbag recall). If you haven't done one, and it is possible, try that.

 

What would the procedure be to do the reset?

Thanks in advance.

 

what are your air intake temps looking like?

 

My iat temps are normally 24 to 30 degrees above ambient,I have the system separated I do need a intercooler I have a leak small one,going back with new stock fuel pump,intake manifold gaskets and o2 sensors,plugs are two months old

 

I was looking at supercharger clutch slippage ,but just dont know because on nitrous the car picks up 11-12 mph on both ends with a 150 shot

 

Not positive if it is for an SRT-6 but here it is copied from 180's list of documents.


Throttle Reset




From the original post by danimal on 08-15-2006


1. Get in your car, it doesn't matter if you close the door or not.
2. Turn the key to the on (not start) position.
3. Press the gas pedal to the floor with the key in the "on" position.
4. Hold the pedal to the floor for five seconds, then turn the key back to the "off" position (don't remove the key), then release the gas pedal.
5. Wait 2 minutes for a full alignment.
6. Drive the car as you always do. In short;


Key on, pedal down for 5 sec, key off, pedal up, wait 2 minutes. Keep the key in for the entire thing.

the sl55 fuel pump will not slow you down, it will provide a more consistent fuel pressure which is a good thing. if you have a datalogger on the car please email me a log and i'll take a look.

 

i did the TB reset several times,I lost serious performance 3/4 mph is say like 40hp

 

Probably just send the ecu to you for a retune,it currently has a immotion tune,how much for a retune an I surely dont want to lose my 10 degree fan mod

 

Holy Moses,removed my intake manifolds gaskets in bad shape but the manifolds are gummed up,can you say intercooler leak,I heard they run 1000$,can this leaky bastard be bypassed

 

No, you can't bypass it since it's cooling the intake air. Definitely explains your slower times though. You can get an OEM Garrett IC from Rob or an upgraded core model from Rudy. Either option is over $1,000.

 

got the manifolds superclean and supercharger ports cleaned awaiting new OEM manifold gaskets,going to run windshield washer fluid since my system is separated plus I have a resoirvor that hold 16 ounces.Going to get a new intercooler with the xmas bonus so I think the washer fliud will be ok with a small leak better that coolant coating an gumming stuff up

 

That doesn't sound like a good idea in my opinion. Most washer fluids contain alcohol, which could corrode the system. But it's your car....

 

the blue washer fluid is 30 percent methanol 70 percent water,after replacing the manifold gaskets an cleaning the gummed up manifolds the car appears to have come alive,i will run a few passes thursday nite on street tires no nitrous I should be back around 89-91 mph again in the 1/8 mile
