Front suspension dry build is coming along nicely.

Looks bloody marvellous

And how big is the HTP pump on the previous page?
Nothing there to gauge its size against

First part of the car ready, increased efficiency HTP pump i've been working on is almost complete. Art or engineering????

What does the other side look like?

O/D is roughly 355.60mm

I'm not sure i've seen it asked or answered, but what is the principal control strategy for the AJ133? Is it just being sent a torque demand that is the result of closed loop catalyst chamber HTHP inlet pressure? I assume with 3 parallel rocket motors, some form of orifice plate or valve will also be necessary to balance HTHP flow into each motor?

Only an engineer...



Looks amazing!

That is rather gorgeous so clearly a bit of both... rather like a set of Oakley X-metal sunglasses

not wishing to be impertinent, but why the lower link design like this?

(what I am getting at is with any movement at all on the joints is going to create some steering angle?)

Gives us the correct suspension geometry. I theory we needed longer wishbones, so we have two seperate arms, giving a virtual king pin

I'm no software engineer, I'll get the explanation in lay-mans terms for you. May be tomorrow though as it's x'mas party lunch/evening meals & I', on my second bottle of Katy.

understand that, are you not worried about load affected steering though?

[McWigglebum4th]

Does that mean the two lower arms cause the bottom of the upright to move in a arc.

And the centre of that arc is your virtual kingpin?

We are going to characterize the pump performance, from there we will be able the simply drive the engine to a rev target.

Spent the morning showing monkey boy around the car, he was like a kid in a sweet shop.

Looks like you have both Warren Mitchell and Mark Steele involved...

Somewhere at home is a copy of Guinness Book of Records from 2009'ish with a two page splurge all about the project (as it was then) and how it would be running the following year. Seriously dented my opinion of that publication.

More fodder for the Photoshop thread



Couldn't agree more with what he wrote, it was fantastic to visit.

My first visit to @BLOODHOUND_SSC today. Can't stop walking around with a big grin, shaking my head at the brilliant absurdity of it all.

You have a pretty good estimate of engine flywheel torque sent out over CAN from the Denso EMS, so also knowing the crankspeed, and drive ratio, you can calculate pump power within a few percent i should think. At the least, this will help tell you that the HTHP flow / consumption and catalyst pressures are nominal during the runs / tests!

The two impellers for the car spec HTP pump arrived yesterday. I rather pleased with them.

And I trought that p0rn was not permitted on PH Those are works of art simply put.

[Blib]

Please sir. What are they made of & how are they made?
