    Let’s say you get 400rwhp NA. I’m curious, exactly how long, how much time, energy and money has been spent to get to 400? Didn’t you start that in 09? Just supercharge the damn thing and be done with it. You’ll be so much happier. You can buy a freaking Honda that’ll beat that at 400rwhp now.

    Why do you constantly say this? While FordNuts numbers a impressive, his is not the N/A rwhp leader. You want the record you need to be North of 400rwhp. Hope you can do it.

    He’s not. He is simply hitting an NA goal then slapping a blower on.

    superchargers are hard on the engine, perticularly the bearings.

    I dont hate them, but they are expensive for an add on, for a perticular budget high or low I would rather have a high end N/A engine than a mediocre blower setup.

    and personally do not think superchargers sound good. the only one I would pay money for would be a centrifugal type.

    If I decide to go with forced induction I will go with a twin turbo setup.

    I would like a hot 5.4 but I am considering a teksid 4.6 tt build.

    Also while I prefer manual transmissions I have had both auto and manual sports cars.

    they can both be done up well and If the car was already a manual I would give more consideration to a supercharger but given the fact I am just going to get the strongest auto Guts I can stuff in a 4r70w, Not sure if I should do the 4r75w since im going with a different motor all together why not. I still have to look at what is involved.

    that being said the shop that is welding the rear end for me is in greenfield indiana, they are called Rods in Progress and they do fantastic fabrication work, they want to do the manual swap for me go figure. so Atleast if I go that route I have a shop I feel good about. But the more I think about it the main use of the car is bad ass cruising with maybe a road coarse or two a year for *****.

    But auto's by nature work well with turbo setups, given the fact I would go dual 57's or 63's something like that its less of a factor because lag will be at a minimum. I have just started looking at cam profiles. I definitly want some low end grunt with some lope and a balanced powerband.

    It will take me a couple weeks of research do nail down what compression ratio, turbo size, cam and stroke prof I think is in order for really maximizing the the overall charachteristics of this engine, I have always been more of an auto x, road coarse guy than drag so a lot of information I find is from drag guys half of which is useless toward my plans.

    My favorite cams were my 263's in the 2.4 4g64t block with a 20g.

    I had and tuned my own DSM link on my old cars. I am not opposed with going to a stand alone ecu.

    I have been focused on the rear end, suspension and have not even looked at what a lot of ford guys do for piggy backs, or ecu mods yet. but

    its on the radar

    Here is some progress so far,

    They did 3 passes and cleared out the channel in between the axle tube and housing. They did a better job than I could of that is for sure. It will be into sandblast and powder this afternoon.

    here is the true track diff.

    waiting on gears and misc in the mail.

    Did your welder have a glass eye or an eye patch?




    Lol. As long as it's solid, no one will ever see it where its going anyway.

    Wow. He is actually a legit welder? Look at the inconsistency, poor to no penetration, and porosity.

    Take it from someone who has been there....$$$

    If you are building a 4.6...put some form of forced induction on it.
    If you want to stay N/A....ditch the 4.6 and start with a bone stock 460 HP 5.0L Coyote.
    OEM, They are light years ahead of the 4.6 technology and durability.
    The problem is matching up the computer systems.
    BUT... I cant' wait until someone puts a 2018 5.0L Coyote with the new 10 speed auto into a Marauder.
    THAT will be the ultimate N/A mod motor Marauder.

    An easy 400+ RWHP with a stout 10 speed auto and 7,500 rpm shifts!
    Plus better drivability and great MPG.

    they do all sorts of fabrication welding on old hot rods and drag cars that is quite good.

    I just want it reinforced.

    also he said they did three times around, had to tig it because of the two different metals and some other stuff I do not recall.

    I would just as soon get a twin turbo 4.6 set up over a stock coyote.
    are they really that much better? seems hard to believe. the mach 1 03 and the 16 gt i was in felt almost the same, don't know if any mods were done to the mach but It was not under forced induction.

    a built 4.6 turbo seems a no brainer over an oem coyote.

    I remember making my very first stick welds like that in junior high shop class. I was so proud!

    I'm not a welder,
    ( I have taken welding classes at the local VoTech....and I did stay at a Holiday Inn Express!)
    but I must agree with what the other posters have said;
    Those welds look like crap....hopefully he had the steel axle tubes clamped in a fixture while 'welding' them to the cast iron center section.
