Eurocharge Contact Info
I suppose I need to keep a positive outlook....and buy a scatter shield!! The pulley I'm looking at says it's steel which is a big plus. I'm also reading that it is at minimum a good idea to size up to a 100mm tensioner pulley to pick up any slack although they profess there's no need to and the pulley won't slip with a stock belt.
Bottom line is I'm not on the track although I might make a few runs in the future. Right now here's where I'm at:
1. 62mm SC pulley
2. 100mm tensioner pulley
3. Single NW CAI (Why? Because my tuning shop said he's ran numerous dyno evals and there's no gains with dual CAI that a single can't produce. His words "how much air you think you can stuff into a V6?") Good point. He professes the gains are more with the quality of the tune as opposed to a huge increase single CAI to double CAI.
4. Dyno tune coming shortly after including TCU
Next phase, 125HP wet nitrous set up. I don't race, but having that sleeper will blow some people away. Stock, as is, I had a new Hemi 5.7 Chrysler 300 roll up to a red light next to me shortly after I got the car. Dude was lining up and truth is I got baited into it, and launched on green. He got me off the line but I was three car lengths on him at the end of a local 1/4 mile run and the last look at the speedometer I was moving past 110mph. Backed out there. I got home and the thought came to me "hmmmm....you are a very well known and respected high school teacher of Criminal Justice and Social Studies. How are you going to explain a criminal street racing charge to you school's principal?" So enough street racing. I might run it on the local track now and then in the future, but there's no need for me to go beyond the above.

Do a search and see what others have done. I would forget the 62mm, it's weaker than the 65mm obviously. Do as you please but get your ducks in a row first.
I hear you. Once I get it on a dyno we will see. I think he can tune it in. As far as the 62mm...its been bought just not received! The dyno shop said he can give it a good performance tune with the 62mm but not push it over the top. Reading all of this forum reminds of the motors I built years ago. "Need a 750 Holly and port/polish those heads!" I built a lot of motors albeit carb motors. Stroked them, 202 head debate as opposed to 194, etc. Always something new. I think with the 62mm, cai, and a dyno tune the AFRs can be managed and a solid mixture ratio established. Once I go nitro (down the line) I will go with the tuner's suggestion. I read all of the list of parts guys are putting on but they are racing. I think for daily driving with just a little kick when I want it I will be fine. Thanks Aero!
Alright....I vented about the lack of response but I need to also give credit where it is due now. Eurocharge did get the 62mm pulley to me.
I'm no pulley specialist, but it looks well constructed, is steel, and as Eurocharge said when they finally did call, it is a new production from about six months back. They've sold approximately 70 and there's been no complaints or returns, and no scattering as others said occurred with their earlier model.
I put it on in about an hour, taking my time. There's no serpentine changes needed or pulley saver needed. The tensioner was more than adequate to pick up slack. It went on easy and there doesn't seem to be any slippage.
I'm no human dyno so I'm not going to make bold statements about gains. All I can say is I've built many small block Chevy and mopar motors. The most torque I've ever got was from a small block 400 that pasted you in the seat. Best HP was a 383 Mag I had in a 69 Roadrunner. I would say this car is somewhere in between at this point. There's a noticeable gain in torque, and the power band is noticeably improved. There's no lag off the line, and it is strong across the rpm range, with the biggest gain from 3800 to 6000. It pulls hard. We all know that stock these SRT6's don't jump off the line...this car does now.
I don't have it tuned yet, as I'm waiting on the CAI from Needswings, but at this point the 62mm gets two thumbs up. Once I put the CAI I will have it dyno tuned and see where it is actually at

That is the weak area on all of these pulleys.
Save
This is it installed. I pulled up pictures of the early version that was scattering. The rivets on this are much better. Apparently the firstproduction was separating at the rivets. Eurocharge professes this new production has approximately 70 sold with no failures. We shall see......
In addition to the 100mm tensioner pulley, I added Latemodel 21's slightly larger alternator pulley and is a nice snug fit of the belt.
