Twin Seq. Dry sumping for beginners :D

Three hours to set up and drill two holes that meet in the middle.

Never believed I'd manage to get them to line through!

Post Mon Feb 10, 2020 11:37 pm

Nice piece of work mate

Alot of thought and good prep does pay off.

Had to hone the last two into alignment. Just a fraction out.

Butterflies tomorrow!

Post Sun Feb 16, 2020 6:49 pm

Took a lot of chopping and filing the throttle to get the thermostat to fit

Post Sun Feb 16, 2020 7:05 pm

loving the work so far.

you thinking of selling any afterwards?

Post Wed Feb 19, 2020 6:45 am

Cheers dude!
If there was enough interest in a group buy I could be tempted.
Would sub out most of the manufacturing though, you can see how long it's taking me to make just one set!

i'm sure there would be interest,
as for subbing the work, i can see your point.

Spindle 1 of 3 in progress....after taking forever to make a fixture

Post Sat Feb 22, 2020 4:43 pm

Two spindles done today

Post Sun Feb 23, 2020 1:11 pm

Just loving this

I wonder how many people actually realise how much thought ,time, and above all ...the skill level it takes to even think about doing this ??

Mart.

Post Sun Feb 23, 2020 5:19 pm

Last spindle finished (managed to put one of the holes 1mm away from where it should be!

)

Made the butterfly blanks too.
Tool on the left goes in the lathe so the butterfly diameter can be turned.

Post Mon Feb 24, 2020 6:23 pm

Oops, One bore is not only 0.4mm oversized, but has a random hump right where the butterfly should sit. Will have to re-bore that one to 40.5mm and make the butterfly to suit

Other than that, productive arvo! Used the mill as a lathe. Amazed that it can move in repeatable 0.003mm increments!

Post Tue Feb 25, 2020 1:36 pm

Phew! Bored the wonky bore to 41mm.
Will just be a bit lumpy above idle!

Post Tue Feb 25, 2020 6:19 pm

Next up, going to try my hand at metal spinning.

Idea is to make six half donuts from aluminium, chop out a section and then weld the halves together to make a tight radius bend.

Post Wed Feb 26, 2020 7:28 pm

So managed to make donuts today, which is good as they're the difficult bit!

Failed to make trumpets though, which is frustrating as they should be simple!

Took a few attempts to get the hang of it!

Post Sun Mar 01, 2020 6:09 pm

Safety first!

Made trumpets today from bits of ali pipe.

Next up, welding!

Also bought the charge cooler from an M3/M4. Planning to take the plastic tanks off and fabricate replacements from more all.

Post Sat Mar 07, 2020 9:53 pm

Welding these bends is HARD!

And I'm a terrible welder!

Post Mon Apr 13, 2020 5:09 pm

After the disaster with sheet metal bends being too small and too hard to weld, I've decided that carbon fibre is the answer.

Making some aluminium moulds and will prepreg them

Post Mon Apr 13, 2020 6:25 pm

I really hope thats a tooling hole mate ????

Mart.

Post Mon Apr 13, 2020 8:35 pm

Ha! I spaced those holes to line up with the slots in the bed.

Forgot to check that the toolpath wouldn't cut through a bolt aaaaaand......CRASH!

Solution: remove the bolt

Post Mon Apr 13, 2020 10:10 pm

Really cool work man. I take it the current situation means you're getting more some time to push on?

Yes and no, had some leave booked and the long weekend meant I got some quality garage time:-)

Hope everyone's managing to stay safe!

Half a mould nearly complete

Now that is cool

Very few people can understand the work, effort and mostly the thought that has gone into this, not just of the moment but the numerous steps needed looking forward to produce this right now.

Post Sun May 10, 2020 5:48 pm

Cheers dude!

Took the M3/M4 charge cooler apart today,need to make a mock-up of the tanks then order material. Looks like it should be quite compact.

Also need to shift the cooler core away from the trumpet inlets.

Post Mon May 25, 2020 4:35 pm

Swapped the fuel rail for an M50 one which puts the pressure regulator at the other end.

Started to fab the plenum too.
Mixture of 1.6 and 2.0mm material is much easier to weld than the 0.9mm stuff I tried to make those bends from

Post Tue May 26, 2020 4:34 pm

Lots of hammering and crushing and we have two hems.

Idea is to replicate how BMW secured the tanks to the core.

Post Wed May 27, 2020 4:48 pm

3 hours to fold up one piece of tin

Post Wed May 27, 2020 5:58 pm

you've fat more patience than i could ever have, & the level of work is astounding.

Post Wed May 27, 2020 8:55 pm

And to think I got excited when I cut my first thread on my lathe the other day

Post Thu May 28, 2020 6:52 pm

Thread cutting is a skill in itself!

Other end tank ready to weld on tomorrow

Post Fri May 29, 2020 4:37 pm

WOW,my welding is terrible! :Lol:

Not too far from having this finished though.

Post Fri May 29, 2020 6:58 pm

Please dont knock it mate , you know how I feel about your abilities !!!!!

Mart.

Post Fri May 29, 2020 8:29 pm

Thinking of grinding the welds flush and going over them so they look nice.....er.
