updates?

 

[DaveMush]

By the looks of it, are you driving the supercharger directly by the loop going upwards in the image? Placing the supercharger directly over the lower intake manifold in the valley.

What's your thoughts on the feasibility of driving the s/c placed to the left over the valve cover. Near the TRD placement?

I know there really is only one path to get the belt upwards between the vvt-i line and the engine mount.

 

[DaveMush]

Love the progress.

Do you feel that what you have worked out could also be adapted to placing an aftermarket s/c over the bank1 valve cover?

 

[DaveMush]

My issue is that I'll be using a twin-screw and an integrated ATW IC in the manifold.
So this will likely place the S/c over the bank 1 cylinder head and back near the rear edge of the engine bay.

So as long as getting the belt back in that direction is a possibility, I'd be interested.

I do know that as it stands, you said the belt length you are using is already quite long.

 

[DaveMush]

Sounds good! Looking forward to it all.

 

[DaveMush]

I completely overlooked the difference in the VVt oil feed line.
I shall have to look into that.

 

[DaveMush]

I already updated to the 2010+ solid metal line long ago.

So by the Lotus SB posted, there is not an all metal line for supercharged applications?

 

[DaveMush]

The M62 was pretty much maxed out on the 1MZ.

 

[DaveMush]

Nope, I'm referring to the same line for bank1.
The same line was affected on all 2GR equipped Toyota's. There is an all metal supercession part starting around 2010.
Although, it still follows the original non-supercharged path.
As for the gaskets for the upper bolt and vvti screen filter, I've got plenty.

 

[DaveMush]

Exactly sir!
(I updated the line on my 2007 RAV4 also, so I've bought two)
I just won't feel the incremental cost savings. Since I need to buy both forms. (The all metal line for both supercharged and n/a applications.)

So is there an all metal replacement? Or just an updated rubber hose and clamps?

 

[DaveMush]

Oh if I only had the money. I'd be all over it.

It certainly would save me the time of engineering my own. Although when I succeed, it will be a one of a kind car. That I have built every part of.

I do find it interesting that they packaged the supercharger forward of the intake manifold. Kinda the opposite of what I had figured. And the opposite of what I had planned for myself.

Seems like it would make the overall height taller in the end to do it their way. I wonder what the clearance is between the discharge port of the s/c and the inside of the assembly cover. Since the discharge port is so small compared to the overall width of the assembly, it wouldn't require much clearance height at full width to flow the required volume of air.

That's actually my project.
Whipple Twinscrew with quad-core Laminova ATW IC.

I have a spare engine on its way, and have also contacted 6 different suppliers for wiring terminals to be able to do harnesses. I have A LOT going on all at once at the moment. But I taught myself CAD to be able to design my intake manifold. Now I have the issue of having to teach myself how to get my 3D design into 2D for .DXF export in Fusion 360.
Then I have a Waterjetter lined up for that.

Then I have to design my belt pulley system.

 

[DaveMush]

They can be speedy yes, but there is so much surface area per core with VERY minimal pressure drop.

There are a few OEM's out there that have used them too. GM has used the Laminova cores in the Cobalt SS and some of the Cadillac S/c vehicles. Although they are non-standard core lengths.

The advantage to these things is their compact size, laminar flow with little pressure drop and incredible surface area.

They also make cores for fluid heat exchange. Oil coolers ect.

 

[DaveMush]

My understanding is that Lotus uses a standard Toyota engine loom (and connector), but they use a proprietary connector for their body side connections to the ECU.
If thats the case, an off the shelf adapter harness for the Link Fury standalone would allow the engine harness to plug right in, but some adaptation would be required on the body side.

To anyone still interested in a TRD/Lotus TVS1320, I do have one currently for sale.

Mainly, it’s posted on the FB Marketplace.
S/C with approx 50 miles, factory S/c lower intake manifold, full set of Toyota Blue 500cc injectors, and Marc’s upper idler pulley assy.
