In a nutshell it won't fit a truck motor without some minor mods, it will foul both the fuel filter bracket in the front and the accelerator brackets in the back.

But that's not my concern. I'm passing this one along to someone with a greater need who disposed of those brackets long ago.:angel:


Hey Dr Ben, do you want to run some CFD on these?

I have just chopped the top off mine with a mill so I can insert a laminova inside. They have a special filter bracket. Accelerator brackets???

Happy to run some CFD.

Truck motors have an accelerator linkage bracket by the back end of the intake manifold, if you've got one it'll foul the end of these manifolds. If you don't have one it's not a problem.

I can't remember if I emailled the old manifold through or not. Do IGES files work?

Any photo on that one interested in the set up as may otheres be.

We need to convert to STL. If you are able to do it that would be preferable (especially if you can check the file is OK.


Garry - will take some pics when I can get hold of a camera.

STL files are on the way.

Also let me know what flow rates and temps you would like run?

I reckon two runs.

2000rpm max torque.
15psi gauge.
60C air temp (good intercooler).
90% VE would be around 878 cc/cylinder, 58.53 litres/sec.

3000rpm max power.
Same pressure
Same temp
85% VE would be around 829 cc/cylinder, 82.9 litres/sec.

How do you get on with valve duration etc? Is it possible to set the inlet conditions and let the valve duration and cylinder size set the flow or set the flow and mimic a cylinder and valves?

So, my 4BE1 manifold has gone to a better home in Texas.

Mmmmm - red. That will make it go faster than Isuzu black :p
Is that a compound turbo setup Dougal?

Steve

That one goes very fast indeed, the fuel pump is capable of roughly 12 times the stock fuel output (850cc per thousand shots, stock is 70cc/1000). It has had compound turbos fitted, but in the pic that looks like a Holset single turbo. HE351 or something like that I think.

That's Randy, calls himself Carcrafter and he's been on here.
