    Here are a few pics of the downpipe build





    Here is the modification made to the cold pipe, this compressor housing is much bigger lol

    My buddy thought since this turbo had the MAGNUM ground off the cover he would fix it


    Here are some complete pics



    Here is the new filter

    I built the rest of the exhaust with 4" mandrel bends and a dynomax bullet. Here is an idle video
    https://www.youtube.com/watch?v=QiQt...NTAmWg&index=5

    Here is a 65-120 run on 13.5 psi

    https://www.youtube.com/watch?v=bAGR...H7Q29_E3NTAmWg

    I then had a weird IAT sensor problem but that wound up being just a bad sensor so I swapped it out and the fixed that. Then it was running extremely lean for some reason. Like 13.2 afr at wot @ 14psi haha! So I figured out the problem, clogged shitty summit filter. So I went to the local speed shop to get a replacement element. They didn't have and element but they did have a big ass filter and it was only $47 with tax! Check it out!




    So that fixed my fuel problem, in fact it gained 4psi of pressure at idle lol. So of course I had to retune it to adjust for the abundance of fuel now. My IDC was at 80% now its down to 60-62% so that freed up another 150 hp worth of fuel lol.

    Next thing on the list is some 15x10 wheels for the new slicks my buddy is letting me use. They are 29.5/10.5/15 stiff sidewall mickeys. They are going to be sick! Im sure itll cut consistent 1.5x's with them. Here they are next to my old Hoosiers.





    So that's where Im at now, waiting to get some rims for those slicks and then Ill hit the track. Im expecting some mid 10's on 15psi @ around 130mph. Next mod will be an alky control kit since Im kinda pushing the limits of pump 93 with 15psi. I also want to get an electronic boost controller, either ams500 or boost leash.

    Also had to pull my dad out of wet grass TWICE with the race truck bc his 4wd was acting up. He had to swallow a little pride that day

    It amazes me how your truck is always improving and never breaking! Working on a forged 370 with twins but its gonna be a slow build. Hows that waste gate sound dumping by the door?
