    72 Dart Swinger 3.6L Pentastar +T5

    A nice added benefit of a modern engine is Variable Valve Timing! You can change the Intake and Exhaust Cam Centerline independently and thus overlap Before we installed the Edelbrock Supercharger, we got our 3.6l swapped 1972 Dart Swinger test rig on the dyno for some Pentastar R&D. First...

    Its the only 3.6l Pentastar supercharger we make. Should be making at least another +100whp https://www.edelbrock.com/e-force-supercharger-for-2012-14-jeep-wrangler-jk-3-6l-1527.html

    We'll have to see how the added power of the supercharger Helps or Hurts my times at the next autocross.

    More install pics Low temp Radiator for the IC fits nicely in front of the LX Radiator The Edelbrock Wrangler TVS 1320 needed its intercooler water lines changed to 90s to clear the firewall. I had to switch back to my 3speed wiper to clear the back of the blower. The Wrangler IC water...

    With all the NA dyno tuning done, its SUPERCHARGER TIME!! I have it currently running well with the cams still where they were NA. She'll break my sticky autocross tires loose in 2nd gear easily enough. The plan is to get back on the Dyno and sweep the cams again to see how adding 7-8psi...

    Been a while since my last update. Finally got her on the Dyno for some tuning. Mostly focused on tuning the VVT and testing different Pentastar Upper and Lower intakes. Overall gains were +25whp and+19ftlbs Full disclosure: imo that dyno is reading a good 25hp too high but the gains from...

    Its plenty strong but in my opinion this is just not worth putting money into. Its beat to hell and needs a new diff, gears and at least 1 axle, which no one seems to make new ones anymore. I have an 8-3/4 & 489 to build or throw in a modded 8.8. The 8.8 has more options for diffs, axels, disk...

    Final Alignment specs. Close as I could get it Right/Left I did a quick bubba test for camber gain at roll. With the wheel at full lock + 2" Roll, the "outside" wheel is around 0 degree camber

    72 Dart Swinger 3.6L Pentastar +T5

    Did an alignment and weighed it. My alignment machine doesnt fit on the 18" so i need to use 15" wheels which are a lot heavier. Take away: Heavier than I thought but not bad for 15" Steel wheels(+100lbs?) & full interior. +6 degree of Caster and Bump Steer kit is awesome 4 Corner weight...

    With 300hp and 4.56 gears, its pretty peppy alright..lol The supercharger and a more sane axle ratio should be a better combo overall. Seems to me that if an A-body doesn't have a small block, it has a G3 Hemi. Seems more popular than a big block for sure.

    I finally found my putty so I checked the hood clearance to the 1740cc with a .77" spacer......Not good A rib on the housing hits the hood. It wouldn't be the end of the world if that rib just disappeared.....BUT it somewhat dashes my hopes of fitting a larger 2300 or 2650 blower without...

    Its less than an 1" from the end of the nipples to the firewall. But the nipples are close to 2" in length. So I'll just knock out the steel nipples and tap it or weld in a 12AN 90degree

    A quick check says it hits a 2speed wiper. A 3speed should fix that.

    But the Edelbrock SC for the Pentastar is small in size compared to others, like Magnuson 1900cc So i wanted to see what else might fit. Only viable option from Edelbrock is a 1740cc used on the Colorado. So I first did a little CAD practice to see where things may wind up. I modeled the...

    It been a while since I posted an update. 4.56 gears suck and my 8-1/4 needs some TLC anyway. So I'm Trying to decide between building the 8-3/4 I have or swap to an 8.8 Picked up another T5 since my 1st and 2nd gears need to be replaced anyway and the cost is about the same. I also picked up...

    I used a 3.6 NAG1 bellhousing to mount my T5 manual. 3.6 came out around 2011-2012 & all used NAG1 before the 8HP 8speed came out around 2014-2015 3.6 Charger/Challenger 2011-2014 3.6 Jeep Wrangler through 2017 maybe a few years of Grand Cherokee 2011-?

    Jeep 4.0 in 69 Barracuda

    regardless of engine 3.6 or 4.0, the Down stream O2 isn't needed, just the Upstream O2 The only Chrysler PCM to actively control fuel pressure is a Hellcat/Demon. So that TJ 4.0 pcm should expect a static 55-58psi at the dead head fuel rail like most Chryslers. The easy way to regulate fuel to...

    Yes but as my initial post stated, the 3.6 had what I wanted. If it only had a less objectionable exhaust tone, it would be a home run

    Except the NAG1 does and is easily swapped. Jeep JK Wrangler guys swap their 3.6 Nag1 Bell for a V8 NAG1 Bell when they swap in a Hemi. I picked up one of these 3.6 throw away, NAG1 bell housings and used it for my Manual trans.

    275hp for the 4bbl and 290hp for the 6bbl were both Gross numbers Big difference between Gross J607 vs Net J1349 that new engines rate at Cold Gross crank J607 Hp of a 3.6L is probably closer to 330-340hp 100% Stock 1970 340 Dyno Sounds pretty close to stock 275hp "The 340 fired on the...

    imo "ticked off" = Cam and headers A stock 72 340 was only 245hp net. The stock 3.6l has over 50hp more net hp. So take a stock 72 340 + Cam and headers to add 50hp and you're at a bone stock 3.6L net Hp My stock 3.6l Dart ran the 1/4 in ~14.3 @99mph(w/ a terrible 2.2 60ft) A Good 1/2...

    That's awesome but this bit is 100% Fake News: "its tight packaging makes this virile V6 ripe for restomods; a 60-degree cylinder arrangement and integral exhaust manifolds shave excess width for plentiful piping and steering clearances" The truth is that Valve cover to Valve cover, the 3.6l...

    3.6 Pentastar oil pressure sender woes.....

    not that much if you look around a bit. Dorman 926-876 $166 at Summit $200 at Oreily's $238 at Advanced But the water/oil Cooler block assembly changed in 2014 so it technically doesn't fit your 2012 without updating to the newer cooler.
