Mykk's BMW V8 T-bucket, version 1.5:

[Mykk]

Finished the homemade 'Header adapter'. Tested it out on Bucket #1:









Fired it up, cycled through a couple different kinds of mufflers held up to the collector. The one I have been using is still the best sounding option. Started lining things up on the 2nd build.

Lining up the muffler to the frame looks nice and even but it gets real tight against the body and I don't think I can sneak the turnout in there.





I think I'm going to have to angle the muffler mounting V'd out just a bit for clearance.

Headers, Mufflers & Turnouts tacked in place. I'll have someone cleanly TIG them together for me rather myself MIG welding them.

Had an idea for the ignition. Rather than individual coils per cylinder that get fired in waste spark anyways. Use self igniting 4 cyl waste spark coil packs and run cloth covered ignition wires from the coils to under the plastic covers on the valve covers to the cylinders for a 'vintage' look.

These coils receive the logic level 5v triggers from the EFI, no need for external drivers. I'm debating 90 degree boots for low profile or straight terminal and points type boots for the vintage look. I don't think I'd be able to arrange the coils in a way to mimic a distributor cap.



I've mapped out a few ignition lead routing options and I think this layout will appear the cleanest:



The fuel injectors sitting in the throttles are coincidentally from a BMW, they have the extended nozzle that I like, a standardized EV1 connector and a manageable lower flow rate (20lb/hr) that will be easier to dial in for idle and cruise.

Beautiful engine

Adapting aftermarket ITB's from a different application. After some cutting & grinding and making spacers I'll be able to get these manifolds to bolt down to the BMW heads. I even like the short stacks.

Oh yeah the shorter stacks look just right.

Oh yeah the short stacks look perfect. Jaguar superchargers are cool but the throttle bodies make it say VA VA VAAAROOOM. Something about 8 throttle bodies on a BMW V8 makes me &

The idea for the main fuel tank. 8" x 28" aluminum tank under the cowl with the filler through the center. I'm sure a more talented fabricator then I could of come up with a snug fit tank to utilize the space more efficiently.









It won't leave any room for gauges or switches, but I have an idea for those.

I was dreaming of a big flip up Cobra style filler cap, but the cowl shape doesn't lend itself it to that style of cap. So instead I'm thinking a smaller Monza style flip cap. The tank will be supported by the arms used for the steering gear for the cowl steering, however the box will be mounted lower then it currently is in the other Bucket.





The tank hanging down below the dash does look like a space hog, but there is still plenty of foot, pedal, steering gear and bellhousing room.

Curious what will be the MPG of the BMW? A 6 gal tank on a V8 t-bucket reminds me of when I had a 2 gal frisco tank on my panhead chop. Lots of praying there’s a station at the next exit but at least you’ll have a fuel gauge. All tho it was great filling up the bike for under a buck.

As it is.... I put 6-7 gallons in my current 14 gallon tank every 1-1.5 weeks. Granted I'm not doing long road trips, but I do romp around town almost every day. I figure without the supercharger it'll be less thirsty.

Frustrated with the lack of aftermarket windshield posts available on the market I found a set of Model T stanchions and an upper windshield frame with intention to modify for the build. While awaiting for those parts to arrive CCR announced they have windshield posts back, so I have my order in for those.

Frankly I'm relieved, I was feeling guilty about cutting up these almost perfect set of original stanchions for my fiberglass T-bucket build. Even in mock up having an idea of the windshield proportions really brings the build together. The top of the tape is 12" above the cowl, where the windshield height was going to land using the Model T top windshield frame.

The aftermarket windshield frames are 11" or 14", I'm leaning towards the 14" height for this project... although that may look too tall.

Can I just say I'm beyond envious, jealous and amazed by your talent. If I knew a 10th of what you are able to do I would start my build when I get home from work. As it stands, I will probably just lurk here on your thread and dream about getting started in the next decade.

 

[Spanky]

Mykk, mine is 14" and though an 11" or 12" might look cooler, the 14" keeps the bugs outa my face!

 

[Neshkoro]

Some years ago I had a cracked windshield. I had a piece of gray tinted Lexan. I cut it to the width I needed. The height couldn’t have been more than 10 to11” high. It looked cool but was just too short and caused a lot of unwanted crap in my face. I replaced it with a new piece of windshield glass cut to the original height. Not as cool looking but much more practical.

Just make sure that when sitting in the car the op of the WS in not on the horizon. You'll find that you are trying to sink down in the seat or or sit upright all the time.

That is good advice, Thank you

You can’t learn any younger! Start now! When skills get better you can redo if you want. Welcome to the wacky world of t buckets!

What did you pay for the stanchions? I have 3 sets of those (not as good) that I need to price and sell.

$100 for the pair

Got ya, makes perfect sense. Guess that’s the best thing about building a car for yerself
