tim, just curious as to the time it took to dev, proto and then get the production units made for the CAS setup?

This is a good one! PF represent! 3XL tee's and stubby coolers for all!

I'm a little smaller than Bigmuz, 7xl.

Another good tech vid guys!

Good wiring porn Tim, welcome to come and wire my shit up anytime.

Thanks Bro, would love to help out if I can.

That was a great episode. They keep getting better.
I think you could have used a better actor to play Tim though.

John Candy would be my pick.

Im a married dude with kids and full time job. Took me ~7 months. Crack did my CAD drawings, JasonB helped with bench testing.

FJ20 and A-Series are next, then moving onto other models of cars i hope.

As a side project, thats very good mate, well done.

Al just gets better and better as a "TV host".

His on camera presence has really come into it’s own. Even from the first skid factory to now it’s always getting a little better. Each vid there seems to be a little more confidence in front of the camera. Big congrats.

Also the last skid factory the guys nailed the sound over/engine noises balance with the 1600 on the dyno. Was a lot better than the 32 dyno vid. Guys are smashing it!

Those carbs were working pretty well really before , other than carbs being shit carbs, the actual WOT power output was quite good relative to efi.

Wonder if they were dyno tuned carbs or just guessed/fluke settings

Well, today I learned.

Look in the video section of PF there is a thread called Street Machine Carnage with over 500 posts about the show.

What size chokes in the Webber's VS the bike carbs?

4xl Marty btw

[takai]

About 80tb, backed up 3 times. Every shot since the day we started. Comes in really handy when we refer to it which is actually not that often. Data wrangling was a big part of my previous jobs in audio so it’s a hard habit to break. I think we’re getting near 500 videos, not sure, not counting

Should have asked what software you guys are using for video editing and synchronisation? Being able to churn out multiple camera edits with good audio sync is really good.

Nice work. Looked like a fair bit of spark scatter in the original dizzy?

Oh, and they're socket head cap screws

Muz, Busa TBs are 44 or 45mm depending on year.
Intersting that rather than re-racking the TBs like bike guys regularly do to sort out the spacing when converting carb'd bikes to efi, it's done in the manifold. Is it a fabricated piece? Or cast?

loved the little easter eggs all through the episode hahaha

It was fabricated. I'm exploring options of having it cast or CNC at the moment. I'd prefer to keep the OEM spacing.

I decided to keep them together as it suits the air filter arrangement and keeps them compact. Also don't have to mod the linkages or fuel rail.

People aren't going to buy my shit unless its simple and cost effective. The more mods you have to make to stuff the more it winds up costing.

The end game is to offer L-series EFI conversion bits. I'd like to offer all the little bits you need to make it work. People can buy it all or just 1 thing.

Manifolds, air filter options, ECU's and wiring, sensors to suit the engines etc.

Makes perfect sense. I guess I'm just so used to seeing it done it was a surprise to see OEM spacing on them. Re: casting, I think it's LSX400 on here who's family run the foundry in Maryborough, might be worth a chat?

Lots of factors to consider with that. Big upfront cost of getting a pattern made and then casting. Then the 2nd processes required to 'clean them up'. Probably a lower unit cost after the first 20 are made. Or my CNC guy I'm using in wang-dong who is turning out awesome stuff. No pattern, no 2nd process. Repeatable costs and designs easily tweaked, probably a slightly higher average cost.

I would only ever go into production if my shit fits a LHD 510 with a brake booster. That's the honeypot of customers for this kind of thing.

3D printed wax investment casts? would need to deck the mating faces and tap a few holes but fettling wouldn't be required.
