Thread: I've got a dream: BMW powered RatRod/T-bucket

  1. #1

    Default BMW V8 powered Tbucket

    Hey guys, here's a few pics from my latest project. I started putting this engine together to go into my BMW E34 540i/6. But as I got moving along with it I shifted gears and decided to go an entirely different route. I want to build an old school hot rod based around the '23-'27 T-bucket, I'm picturing a modded drop frame. Drop solid front axle. Jaguar independent rear end. BMW V8 & BMW Getrag 6spd manual trans. Track-T, deluxe or turtle deck T body. 32 or 33 x 17.5 thru 22x15 (or bigger) rear wheels.

    The current project:

    Late 90's BMW 4.4L M62 shortblock with RaceWare head studs:



    Early 90's 4.0L M60B40 from a 7 series to donate it's heads & cams, double roller chain timing set up and other misc hardware:





    Double timing gears, idler & guides on the M62:



    M62 pistons sit +.025" above deck, found roughly 4cc of dish in piston crowns.



    Cylinder heads back from machine shop for rebuild:



    Measured 52cc in chamber volume:









    Belt driven intake manifold, Late 90's Jaguar Eaton M112 supercharger (GenV), also using the jaguar water to air intercoolers and injectors/manifolds:



    Setting up cam timing:









    Found the O.E. cam timing made for an 108 ICL & 108 LSA with 211 Int / 206 Exh durations @ 1mm valve lift. 9.65mm Int lift/ 9.4mm exhaust lift. I've now set cam timings for a more boost friendly 110 ICL & 112 LSA

    In order for the supercharger to sit on the adapters for the BMW heads it needed a few mods:





    Pulled off, flipped and pressed back on pulley:









    My measured specs:
    Engine: 92mm bore x 82.7mm stroke, 143mm rods.
    Pistons: +.025" above deck, 4cc dish
    Heads : 52cc chamber volume
    Head Gasket: MLS 1.74mm compressed thickness
    Static compression: 9.6:1
    Naturally aspirated dynamic compression using modified IVC degree: 7.94:1 (at my living altitude)
    Target boost with Eaton M112: 8-10psi

    Plugging all my info into a dyno sim:

    For engine management I've decided on an opensource DIY system called Speeduino, uses an Arduino Mega2560 controller.



    I've test fitted the EFI system to my running E34 540i with it's original M60B40 4.0L V8.

    Since Speeduino has 4 injector channels and 4 ignition logic out the V8 will be run in waste spark and semi-batch fire by pairing up the two cylinders that are 360 apart.

    On the car I converted the BMW C.O.P over to two 4 cylinder waste spark coils using all MSD products. On the supercharged M62 I think I'll keep the C.O.P's but run two MSD DIS-4s triggered by two Bosch 211 modules to convert 5v logic out to ground to fire MSD's



    Using the engines original VR sensors I loaded up firmwares, loaded the Arduino Sketch, wrote a base tune. Fired it up and since speeduino uses TunerStudioMS I let the system self tune the VE map for me based on wideband input:





    First fire up and first test drive:

    Another experiment I wanted to play with was a digital dash by way of on-board carputer using a RaspberryPi





    Still tinkering with the idea, but with the use of a GPS sensor and wire in Oil pressure sensor and fuel level to Speeduino I could just simply run a dash screen in the hot rod without any gauges.

    well done. thats some excellent fab work and I'm digging the arduino setup. I've built 2 MS cars and working on a 3rd now

    oh man this is rad.

    love the open source ecu and the digital dash running on Raspberry Pi

    whoa, I can't wait to see this thing sitting in a t-bucket, and I can't imagine how gnarly its gonna sound

    Most of the engine build and wiring is way over my head, but I love the fact that it will all be crammed into an old chassis.

    this is great. Love all the arduino stuff. Inspirational. I need to learn some of that.

    Decided to take another turn in the engine build:





    Speeduino will also be releasing nitrous controls in it's next firmware update :-)

    say whaaaatttt??? way cool. how much power are you hoping for with nitrous?

    Are you going to have room for the coil pack harness with the spike valve cover bolts?

    Shown above is a wet shot, I'm currently changing the fuel solenoid over to a 2nd n20 solenoid for a second stage. 1st stage will be 60hp & 2nd will be 150hp. Speeduino just released 2 stage nitrous controls in the software that will increase injector pulsewidth and retard timing while active. I'll need to change out injectors for larger flowing ones. The idea for the nitrous was to cool IAT for short blasts, I'll likely downsize jets to keep it manageable.

    I've run them before on a similar design engine, it's tight but it fits. Plug the coils in first then bolt them down.

    Great work!! Await updates!

    I've got this plan. Turn these forum posts into youtube updates and a series documenting the progress of the build. First one will be of the engine, next one will be fishing the transmission out of the donor car and mating it to the engine. 3rd will be the ordering of the T bucket kit from Speedway. Then unboxing...etc.

    Once the car is together enough to run, it'll be time to start tuning and working the kinks out. Then comes the entire plot of the series; Take my home built hot rod on a road trip. Leaving my little Arizona town and cruising to Los Angeles (where I lived in 2011-2013). Visit some of my old LA hang outs, join the Hwy 1 in Santa Monica and cruise the 1 all the way up north to San Francisco (where I grew up) and beyond, Bodega Bay. Visiting old memories and making new ones. Making video updates from each coastal town and view along the way. Tuning the EFI on the road, fixing things that break on the side of the road. Meeting people along the way. The restaurants and food...

    Does making videos mean anyone will care, nah. But I'm going to do it anyways. My biggest concern is the amount of down time in between progress as funds allow. Working a $30k day job means that things like the $4k kit car will take months of saving up for it. $1200 worth of brakes is a couple months...etc. Still going to do it.

    Started tearing apart the donor car. My used and abused HE53 E34 540i/6. I'll transfer over the Spec lightweight flywheel & clutch over to the M62 after a rear main seal install. Then bolt the Getrag 420g to the back of the M62. I'll try to utilize as many parts from the E34 as I can, part out the rest and recycle the shell.

    Due to a massive oil leak from to a stripped out cam cap stud for the valve cover hold down, and the fact I just removed & sold the differential the car needed a little nudge from my truck to get into the shop.

    great work so far, that engine looks awesome. what is the name of the channel? would love to follow your journey man.
