For those that may have been following this, I have added pads suitably sized to machine for injectors.

Due to the size and length of runners, there is only room for 3 injectors.

Several people expressed interest in having this feature, hopefully this satisfies them.

Let me know what you think, i'm keen to continue on with the pattern.😎

There has been a bit going on in the background over the 'break'.

There are some new products coming soon, a couple that have gone live already.

I have also, finally got around to adding my Speedflow Stock to the website.

Casting pattern 3d model for the Holden Grey Weber intake is nearly finalised.

Stay tuned for some updates!

A couple of weeks ago I had this cool little job come to me.

It was a relatively straightforward "can you fix it"?

But it came with a cool story.

An engine builder local to me, helps out with the mechanical side of a 1986 Benetton B186 F1 car.

This is the shift detent spring retainer for the gearbox from it.

The old component was aluminium alloy for weight purposes and the replacement part I have made from 4140. It's a couple of grams heavier but I'm assured that vehicle weight isn't as important as it was in 1986

I dug a little deeper into the history of the car and found out that it is the car that Gerhard Berger raced in Adelaide in 1986 and that Gerhard himself will be in Adelaide for the Adelaide Supercar Grand final and will be driving the car for track demonstrations.

It's a privilege to have played a very small part in helping it hit the tarmac.

Recently I had Jimmy contact me to ask if I would consider making a true 12 port SU intake.

Coincidentally I had been thinking about dusting off the casting pattern that I inherited with the business, but had never cast...

Fast forward a few months, a couple of very minor pattern repairs, a few jigs and fixtures later and Jimmy gets his intake.

I did cast a second set at the time but it looks like they are already sold!

What do you think, should I cast more?

I have a couple of these left on the shelf ready to ship.

Everyone that was waiting has either been notified or purchased already.

Next batch will probably be January or February.

Enjoy your long weekend.

It's like Christmas, but in July, or August, or whatever month we are in now.... anyway the point is, some stuff is back in stock. 😆

Here is the first of our NEW Cam Synchroniser kits.

I'd be interested in sending this out to a customer at a discounted price for testing purposes.

This one is for a Hemi 6, Holden 6 and more versions will follow immediately after testing.

This design utilises the fuel pump eccentric as its reference and has no moving parts.

It has been tested in a simulated situation and performed exactly as expected, but has yet to see time on an engine.

Whoever can offer me feedback from testing in the shortest timeframe gets it cheap.

In the coming months I will be rebuilding the pattern for the Holden Grey intake.

I have started on a rough 3d model of it.

I'd be interested to know if there are any suggestions for changes that could be worthwhile.

Let me know your thoughts.

Enjoy what's left of your weekend.🙂

After a 'productive' long weekend, I have a couple of Crank Trigger Kits back on the shelf, along with a few other bits.

Good evening, followers and customers,
This might end up being a long post, but please stick with me.
You may have noticed that I’ve been almost completely absent from social media lately, and I’d like to explain why.
Due to a combination of some costly business-related mistakes I’ve made (yes, I’m human too) and the ongoing inflationary “cost of living” crisis, the business has found it difficult to continue operating as it was.
This has taken its toll on both myself and my family—mentally and financially—which in turn left me struggling with imposter syndrome and a complete lack of motivation to post on social media.
As a result, I’ve taken on part-time employment to help keep Sonic Injection running.
What this means is:
• I’ll only be available by phone between 9:00 am and 2:00 pm on weekdays.
• I may not respond to all comments, emails, or Messenger chats—but I’ll do my best.
• I will return your call if you leave a voicemail.
• I’ll keep as much stock on the shelf as I can manage.
• I’m still working on developing new parts.
• I’ll try to stay motivated and engaged in posting product updates and the like.
It’s not a huge change for you as a customer, and I truly believe we’re on the rebound and will get through this.
But I can’t do it without you.
All I ask is that you extend a little patience if I fall behind, and continue to support Sonic Injection.
For those of you still reading—thank you, and Happy Easter.
– Luke
