  1. 300C, Magnum RT & Charger RT (5.7L V8)
    I know there must be some differences between the 03-08 5.7 pistons and the 09+ (Eagle) pistons to handle the smaller cylinder head chamber volume in the Eagle motors but I can't find definitive information anywhere. The rods are the same from 03 - current so the pistons must be different. Does...
  2. Want to Buy
    Looking for something to put on my MSRT8. Its a forged 413 with 8.5:1 compression. Whats for sale?
  3. Transmissions Gears & Diffs
    The Circlips that go here. I have no real experience or training on these kinds of axles. What purpose do they serve? Is it the CV joint at the wheel end (or perhaps both?) has a compression range and the circlip makes sure all the movement is in the joint and not in the differential splines?
  4. 3.5L V6 Forum
    2007 3.5 used with 80,000 miles that sat on my engine stand for nearly a year. First installed after new head gaskets, timing belt and waterpump. I do this on all used engines. Ran great after install. Parked it for a couple months waiting on other parts. Went to crank it and made all kinds of...
  5. General LX Discussion (1st Gen - 2005 to 2010)
    I recently bought two Charger R/T's. A 2006 and a 2009. Just a general check I took compression readings. Had one plug out of each cylinder and did nothing but turn the key for three revolutions. The 2006 has 165 +/- and the 2009 has 235 psi almost exact on all 8. Used the same gauge...
  6. Challenger Discussion (2008 to 2014)
    I've developed what seems to be a slight miss at idle and alot of ST knock, 1-5. No misfire codes, but misfire counts on the T2 during start up only. Its e force supercharged so I'm a bit worried I may have an internal or fuel issue. Compression test performed cold, wot, 1 plug pulled from each...
  7. General LX Discussion (1st Gen - 2005 to 2010)
    Ok, long story short, removed heads to install headers. Got everything back and the car cranked but didn't start. Turned over for a few seconds when I stepped on the gas. Battery voltage was 11.68V. Got a new one, same result. For the few seconds it ran P0300 code showed up multiple...
  8. 300C, Magnum RT & Charger RT (5.7L V8)
    I've got a 392 forged Manley stroker, it's listed at 9.6:1 compression ratio with -1.5 flat top pistons. I'm using an Inertia stroker cam 230/241 .556/.560. At the moment I'm running the stock 5.7 heads, so I figure there is alot to be gained with a head upgrade. Running a compression...
  9. Power Adders
    Car is headed to Bfny performance on Friday. Surgeon Erik will installing a procharger(d1sc) kit on my stroker r/t along with an ati od pulley. He is going to do a dyno pull before install. Motor is a 392 stroker built for boost except compression ratio is 10:1. I wasn't sure how long after...

    What compression ratio do eagle heads on a pre-eagle 5.7 give? And for those who have done it what octane fuel do you now use? I have HP Tuners so I can play with the timing to optimize but just curious if anyone out there has run into detonation issues after swapping to eagle heads.
  11. Power Adders
    I have my already built 392 (6.1 stroker) that sports 11 to 1 compression. At the time of build, I never thought I'd want to supercharge it, so I agreed with the builder on this compression. With the Whipple now available, I'd really like to get one. I'd rather not tear into a brand new...
  12. Engine / Intake / Exhaust / Performance
    This little 450 cubic inch high compression HHP/BES stroker with Apache Heads, Harland Sharp Adjustable Rockers, Solid Lifters, Drag Pack Intake and a few other odds and ends is making us proud. Time to start track testing her.
