95mm TB; what Adapter are you using?

Mike@SolerPerformanceLLC · 12-28-2019, 06:40 PM

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.

Excellent work, it's nice to see companies like yours striving for perfection even when it comes to the little details.

Is this something that you will be releasing for the LT4, also? I’ve been considering your 95mm TB for a snout ported to work with a 103mm TB. How would you guys address that transition?

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.

Thanks,

idle quality has greatly improved with this spacer. The old stepped setup must’ve been messing with the throttle trims.

This makes so much sense. I had thought the same thing. If the TB was 95 but the adapter was 87 or whatever smaller, wouldn’t that just defeat the purpose? So doing this with a smooth transition has to be better. Also are you saying that if the snout is opened to 103 then you would just take out the step all together?

USAF, did you mean; LT1/LT4 TB to MSD? That is 87 mm TB to 103 mm Manifold. If so, yes, we could do those too. Is that your current setup?

what is the point of 95-87mm adapter with a 95mm TB tho.... when the IM opening is limited at 87mm, the stock TB would be seamless even

When considering the TB opening AND the blade shaft assembly, the stock 87mm TB isn't really 87mm of free flow because of the shaft and blade taking up space.

So take the 95mm TB into account, it has more airflow than an 87mm TB with the shaft and blade in the middle. So essentially the 95mm TB adapting down to and 87mm opening will utilize all 87mm of airflow while a stock 87mm TB isn't actually flowing what an 87mm opening would flow.

95mm TB to 87mm port isn't going to yield any results as far as I know due to bottle necking. My understanding is the only time this is an exception is with forced induction I believe?

I knew this going in with the ported LT2 to eliminate the bottleneck at the port.
