Ummm Deputy, why do you feel this was targetted towards you? Look...I got no ill feelings towards you. We might have had our run ins here and there and disagreements, but it was just that...a disagreement. I wasn't pointing anything towards you. We all know you don't like John Mercedes and thats cool, to each their own, you have your reasons. We all know I do like John, as he's been the best help to me for seven straight years through bad times and such, helping me on the phone and on prices when others didn't. But, as I said, you have your reasons and thats fine.
Have you ever used split sec tuning tools before????? I have used the FTC-1 with another "crap" product called a Kenne Bell blower.Stock 360 motor with 210B cam,stock heads,PPH's,10 psi and made 350/380 to the wheels.The paxt-a-map used on the delphi beloved paxton blowers IS made by splitsec.So you are right Splitsec is total "crap".My comment ws just a joke not directed at anyone but poking fun of my trouble with the JM nutswingers so its all good I was just :stirthepo and making a joke like I always do.I have no problems with you either or anyone else on here(yes even Brad99RT) so its cool dude.
Few corrections -- It's not backpressure per se that you want, it's exhaust velocity. Too big of a pipe kills the low-rpm velocity, and therefore kills your bottom end. Too small of a pipe will choke down your top-end power. As for the spintechs, they're actually based off of the Kenne Bell headers made for late-model Magnum V8 motors. The reason for the port plates isn't because the header wasn't made for our trucks, but because of the bigger primaries(1-3/4" vs. 1-5/8", which was what the Kenne Bell Headers were). There's no room to run the stock bolt pattern without choking down a couple of the tubes for clearance. You can redrill the flange and dimple the tubes needed if you want to run without plates, but why? It's a PITA to do that. The New Spintechs will be running the same port plate design, and again...it's not because they're not for our trucks, or Spintech felt like being goofy, but it's because of the huge primaries compared to just about everyone else running 1-5/8" headers. Marty's LT headers...'scuse me, Hooker's LT Headers, are made for Magnum V8s, just not our generation Dakota. IIRC, the reason for plates with his setup is for clearance issues down below.
Actually, Marty does more than just give you an off-the-shelf header with some spacer plates. They hack 3" off of the collector and reweld it first. Another clearance issue...lol.A correction here... carbureted motors need a certain amount of backpressure maintained unless the carburetor is jetted to compensate for an increase or decrease in the backpressure. A modern fuel injected motor will be able to respond to a change in backpressure by adjusting the injector pulse.
True, but the topic here is the power comparison between the headers and not whether they have a bandaid approach or not. At the time those headers came out there was no vendor willing to sink money into designing a long tube specific to our trucks. The KRC adapter plates were designed to allow the use of an off the shelf header (Hooker SuperComp 5803, to be precise) with our chassis configuration. Personally I don't care for KRC and everyone knows that, but I think the adapter plate was a good short term solution. Typical for KRC, they decided their solution was worth a premium price at $799 (at the time) and they neglected to tell people that it was an off the shelf header with an adapter, instead leading people to believe that this was their special design. A Dakota owner could have gotten the same package by ordering the headers from Summit for about $300 and then taking a gasket to a CNC shop and using it for a template to make their own 1/2 inch plates.
I do too. I think the time for band aid approaches to our trucks is gone. With hundreds of thousands of these things on the road there should be no shortage of proper parts designed just for us.
Right. Unless one of the truck magazines or Mopar Muscle gets into it, it isn't going to happen. Even if it does, there's going to be a tiff over whether the PCM was tuned properly, were all other things equal, etc. Ultimately its still going to come down to the same thing it always was, and thats cliques of people supporting their preferred vendors. As always, the new guys are going to be the ones who have the hardest time, as they have to sift through years of thread arguments trying to figure out what the science is at the bottom of the holy wars.
I'm glad that Spintech is offering these parts, because it means there's more choice out there for the DD drivers. The more new parts, the more interest in our platform, and the more companies will take a serious look at us. As I mentioned before, there are hundreds of thousands of these trucks out there, and most of them are off warranty now, many are paid off, many are on their third or fifth owner. They're ripe for customization, and I think there's eventually going to be a wave of that, driven by new products.
Unless of course the gas prices make us all ride scooters.
Ok, that makes a bit more sense. Fuggit, it's late...I need to be in bed. LOL!
I'm not arguing here... but are you sure about that? The 5803 was designed for the LA motor early Daks with the 46RH transmission (or was it the 44?) so where is the big clearance difference between the two chassis and drivetrain combos that would require shortening the collector? I just spent a few minutes trying to find the pics that were up on the KRC site (what a mess that place is) of the headers installed in a truck that was up on a lift. I don't remember any clearance problems existing aft of the collectors.
Which is my point, indirectly.
Another insomniac typist like myself :wave:
Tanky, I forgot to address this earlier. I'm not arguing against your point here, but I felt it necessary to point out that not only are manufacturer claims not to be trusted wholly, but also customer claims and "independent" claims. Unless you care to exactly duplicate the conditions of the manufacturer's dyno pulls, you're wasting time. Prior to purchase, manufacturer dynos are only useful as guidelines, not gospel. After purchase, I think a baseline dyno is useful, but only for same vehicle comparisons.
Not really insomniac, but my body clock's been fucked up the past couple days...and had just gotten done wrenchin' on the truck for the night...LOL!
so out of curiosity,do you think instead of a stock throttlebody,but say f&b or fastman,do you really feel they would have been more beneficial with the second setup???
The TB on the truck is a 50mm F&B (one of the original ported stockers they once did before he went billet). It's a demo TB that I have when doing comparisons between different combos of TB/cam setups. In previous tests, I gained 12 rwhp between this TB and the 55x52 F&B-- so there's no question that I would have gained more. Variables that I cannot really cover though are --1) truck getting older, higher mileage aka- abuse 2) different Dyno (can't 100% say that these numbers are accurate for true comparison 3) As with any combo-- won't be able to give numbers on 'said combo' until it's tested--- I was most interested in the curve, and where/what rpm it comes on.
