As many of you know we have already released our Modified 95mm (100mm Effective) TB, while working on it we realized that the 3rd party Adapters we were using were defeating the purpose of modifying the TB to some extent. That is, we are opening and smoothing the flow path on the TB and the Manifold only to find that these 3rd party Adapters were closing down area and posing restrictions downstream of the TB. See figure 1 (straight bore adapter).

Every time the airflow finds an abrupt change of area, it tends to create vortices, these create centers of low pressure where the air recirculates and losses density, exactly what you don't want to happen inside the manifold or at the inlet of your supercharger.

Having seen that, we went with our own Adapter design, and the results were great see figure 2 (Soler Performance Tapered Adapter). But we did not stop there, we also made one for 103mm Manifolds. We can also make them match your own ported Manifold/SC internal diameter size.

The results were great, our screw hole pattern perfectly centers the TB on the Manifold to avoid steps due to bore mismatches. The smooth tapered transition allows the air to accommodate to the contour without causing large pressure drops. The contours of the TB, Adapter, and Manifold coincide edge to edge all around, zero steps.

The same philosophy "one-size-fits-only-one". Once again the once-size-fit-all Adapters don't fit any in reality.

These Adapters are not about gaining power, the point is making them right (TB and Manifold Specific), so you don't lose any of those hard-earned HP's you attempted with your Mods.

I actually commented on this on Camaro6. Lol.

But for those of us with LT4’s that port our snout to accept a 103mm TB, how would you guys address that transition using your 95mm TB?

Mike@SolerEngr

That would likely be the 95-Custom option, let us know the size of the internal diameter of your snout. If it is 103 mm, we can simply modify our standard 95-103 and perhaps remove the bull-noses.

Nice piece you can also re-drill the bottom two holes on the T.B. and dont have to use the spacer at all. I had to do this due to the A/A TI head unit I have on my car. The spacer pushed it out just enough are the plug that has to plug into the T.B. to hit the pulley on the blower. But it works 100%.. Also I have a MSD intake on my car also..Robert

Mike@SolerEngr

Thanks, Robert. That is true, some folks do that. We thought about it, but didn't like the way it looks (thin walls on the mounting legs of the TB), it accomplished the mounting part of the job, no doubt.

Another detail to take into account is that in that case, it will also see a sudden increase in area, see pic below, it also creates recirculation and pressure drops, no as bad as when it sees a sudden decrease. This is why we have the 95mm-103mm adapter, and also because of the MSD manifold has material protruding into the bore at 4x places to allow for screw holes. The seal also runs inwards there. The bull-noses catch the Seal there and allow the flow to smoothly go over those protrusions. The Adapter outlet matches the Manifold inlet edge to edge all around (see pic below).

I have a Lingenfelter adapter plate on my stock 95mm TB and yes, the adapter defeats the purpose of the 95mm tb. My blower is also ported, not sure to what size tho. It would be nice to get me another adapter that eliminates this necked down restriction. When I get my car back from the shop, I'll see if I can take a pic.

Do you have a pic of a 95mm tb with your adapter mated to the back of it, so I can see the smooth transition? Thanks,

Mike@SolerEngr

Thanks, George. Here they are.

Fantastic Mike!!

I am like George, I have your Soler 95TB with the Lingenfelter adapter coupled to my ported blower. You new adapter is just the thing we need.

GeorgeR_Zed06

Wow, thank you for the pics, I need that adapter!!! Is it available for purchase, if so how much for a 95mm one? Thanks,

Mike@SolerEngr

Thanks, George. They are $65. Available here: https://www.solerengineering.com/store

They all start at 95mm on TB side, and end either at 87mm (PN SE9871-95-87) for stock manifold/SC, or at 103mm (PN SE9871-95-103) for MSD manifold. If you have the stock manifold/SC and the snout has been ported, please order PN SE9871-95-87 and tell us the size of your snout internal diameter and we'll customize it it for you.

Hi Mike, do you have an adaptor for a stock LS2/LS7 silver blade 90mm (08 Z06) to transition to the MSD intake manifold? I see there is a LT5 adaptor, but didnt see one for the LS7. Thanks
