You need to get rid of the ESP nanny thats keeping you from roasting the tires. Go to www.noesp.com and purchase the by-pass relay switch from them for $50.00. It's easy to install with basic knowledge and makes all the difference in the world. Cold Air Intake is a better bang for the buck than the Cat-Back Exhaust system, although the exhaust system sound will quicken the pulse and put a smile on your face. Superchips Flashpaq Tuner is also a great item if you want to take it to the next level. I put all the above on my Charger R/T plus a Throttle Body Spacer. I'm researching new tires for the car because I can't get the tires to grab. The small amount of peddle required to break-em-loose is almost rediculous.

This message is for drydenrt: I purchased the NOESP-01 and installed as described in installation instruction. I connected the black from noesp to blk w/green stripe, green to green w/white stripe at the ESP switch. Then attached the red to the violet w/light blue stripe going to the front of vehicle, then connected the yellow to the other cut violet w/light blue wire going to the rear of vehicle. then performed the check as described and no click was heard from relay. My question is, does the vehicle have to be in drive for the relay to operate.

This message is for drydenrt : I reviewed your response and purchased and added the NOESP replay and it works wonderfully. I am now interested in three items you installed on your vehicle. 1. Flashpaq Tuner 2. Throttle body spacer and 3. Cat back exhaust system. I would like to know where you purchased your products from and the brand names. I located several different types of cat back exhaust,throttle body spacer and not found Flashpaq Turner. If it would not be to much trouble, will you please help me with this request.

#7 of 16 There's more mods than listed so far, help build a FAQ
Aug 29, 2008 (12:39 pm)
I've found a few more mods than listed here and am trying to build a FAQ in another thread (Performance FAQ Input needed) to help us all. I'm hoping others who have experience with the mods below can help answer the questions that follow:
Custom Fit Ignition Wire Set (15 hp, $150)
MSD Blaster Coils (? hp, $500)
Cold air intake (14 hp, $300)
FLASH Chip/PROGRAMMER (20 hp, $500)
Aft-Cat™ Exhaust (20 hp, $760)
Performance Headers & Exhaust (24 hp, $550)
cat Mid-pipe (n/a, $450)
UnderDrive Pulley Kit (12 hp, $230)
Cam/Spring/Pushrods Kits (60 hp, $525)
Torque Converter (N|A, $400)
Transmission Cooler (N\A, $100)
Suspension upgrade ($1100)
I'm looking for input on:
- Install Order (What has to go first and what gives the biggest HP gain for the buck)
- install hrs (how many hours to install if I take it to a speedshop or mechanic, so I can estimate installation price)
- hp gain
- Fuel efficiency gain
- Approx Cost (Hardware only)
- does it Void the Warrenty?
- Recommendation Best Value
- Recommendation Best performance (regardless of cost)

My 5.7 Hemi was recently rebuilt by the dealer for a knocking noise. Motor completely torndown and all pistons removed. Dealership replaced rod bearings,main bearing,oil pump, but did not replace the piston rings. My engine had 19,975 miles and I made it very clear that the piston rings are to be replaced and the service director told me the rings will be replaced. Now, I have contacted Chrysler Corporation with my concern. I know that I will probably start burning oil,fouling spark plugs,and even blowby. Do you think i am right. What do you think about this repair ?

The knocking has to do with bearings, not pistons, (unless they were hearing piston slap) so I see no harm done in not replacing the rings, based on the accuracy of their original diagnosis I mean.

Engine has 19,975 miles. All pistons were removed during the taredown. Then all pistons were reinstalled without replacing the piston rings.What is the chance that this engine will now have blowby or excessive oil consumption in the future.

No more than if they stayed in there. You can't hurt them by removing them. You might have greater risk by installing new rings. They might not seat, whereas we know the older rings are well seated.
It really all depends on how carefully they measured cylinder bore wear and how carefully they inspected the pistons and rings. I would think they'd be crazy to re-install worn rings or put pistons into an egg-shaped cylinder bore.
Not sure why your engine started knocking---one hopes it was not oil starvation but rather manufacturing defect or cap bolt stress.

I was told the knock was coming from oil pump out of tolerance. I have never heard such a thing. I post this question to two highly recommended machine shop and both said that they have never heard that. Both shops also said unless the pistions were reinstalled exacltly in its original grove,the possibilities are high that blowby will occur. Block should have been honed and new rings installed and that's the only way they can gurantee repair. This is only what I have found during my local search with machine shops and both agree on piston ring replacement.
