    BMW V8 T-bucket build #2

    The supercharged BMW V8 T-bucket Build #1 has been on the road for just over 3 years now. I decided to start putting together a 2nd one applying the lessons learned from the first build and getting a few ideas that have been in my head out into reality. The 2nd build will focus on making a street cruiser that won't be as aggressive and harsh to drive on the streets.

    It will be the same modus operandi as the first build. Bare speedway motors T frame s Speedway motors fiberglass T-bucket body. BMW V8 & 6 speed manual trans, Jaguar IRS differential.

    This is a long term project so stay tuned as progress is made.

































































    ... you'll notice some obscurities around the build already. Hanging the jaguar diff off a perch from the rearmost of the frame is an idea I wanted to try along with the transverse leaf spring under the diff for the rear suspension and rear facing calipers. The rear leaf is mounted on a .250" thick steel plate bolted to the Jag control arms. I still need to come up with a graceful way to transfer the loads from the underplate up into the top perch or the frame.

    The fuel tank under the cowl: A more talented fabricator could have made a tank that utilized the space better than the universal round tank I have in there, but it'll work. The location was a decision made simply because I didn't want to have a tank out in the open behind the tub again, I also like the center cowl filler like they did for the original model A's

    The digital gauges: I knew I would have difficulty fitting mechanical gauges with that tank behind the dash. Using a 7" DSI touch screen ,Raspberry Pi 5, full version of the tuning software, Auto-Tune making constant live changes to the running VE table and and endlessly customizable gauge layout I think I'm okay with it. I do wish I didn't run a mechanical fuel level gauge through the cowl, but I've done my best to countersink it as far it'll go and I'll just pay mind to fuel level getting in and out of the car rather then a visible gauge from the drivers seat.

    The grill shell was a suggestion and I'm really happy with the results, it's two top halves of '32 steel grill repops with one flipped upside down.

    The steering gear is from a tri-5 chevy, reversed and modified for mounting. It has a 16:1 ratio compared to the 24:1 of the Ford truck box in build #1.

    The engine sitting in the frame for mock up is a BMW M62B44TUB version of the M60/M62's. I like to use the earlier version of the engine without the variable intake cams. The timing chains and idler gears from the earlier engines are preferred over the plastic U-guide and single row chains used in this version of the engine. The standalone EFI controller does have the ability to control variable cam timing I just don't have experience setting it up. I'm not opposed to using the variable intake cam and it might be interesting to use on this build.

    The ITB's and tall stacks is a recent decision, I am still collecting parts to make it happen (thus the MsPaint rendition of stacks in the photo) But it just feels right for this build and it'll provide the Ying to the Superchargers Yang.


    I'll update the thread as progress is made, thanks for checking out my project!

    SO good to see you back on here - it's been too long!

    I'll be interested to see what you think of the digital gages. I was thinking of going that way on the MGB but was scared off when folks said that they aren't visible in bright sunlight which is when I intend to drive the car. So I'll keep an open mind awaiting your experience.

        Adapting over a set of independent throttles meant for the Toyota 1UZ, they are going to need some work but they'll bolt down eventually. I actually like the short stacks too.

          I’m going to be watching closely, as I need more ideas for the whatever project to plaigerise. I’m not proud, I’ll steal ideas from anyone…

                Picked up the native BMW 6 speed manual transmission to the engine. I'm thankful to have located one, I was nervous about finding this piece of the puzzle.





                Now I can make the motor & transmission mounts.

                    Wow!! I just went back and looked at your first build, very impressive!
                    I love how you're keeping the manual trans. Seems like due to space limitations, T-bucket guys usually go auto. Must be a blast hearing that thing bark a V8 tune while shifting through the gears! (I imagine the vibe has to be similar to the Cobra replicas?)
