Fuel does match air flow but stock for stock you still will be limited by your requested torque value. The ECU's will adjust whatever parameters to achieve this. Even if changing the TB increases cylinder fill, the engine will purposely run inefficiently to achieve its targets.
The inlet on your intake is still the stock size, so useing that thin single angle 80-72mm adapter instead of a radius will act more like a restrictor plate then a velocity stack. When I get asked to gasket match stock sbc heads( bevel the edge) I roll my eyes. Making a redundant cross section usually reduces velocity and flow. The pinch point is rarely at the larger cross sectional areas within the induction system. "A" is not the problem. Useing some complex engine math it may be determined that 6 cylinders of this size and this VE at x rpm could have some restriction at the TB. You can change to a bigger one but you will still be limited by the next restriction like the intake inlet which is still the same size as stock. There are gains to be had but you have to apply the "full package" TB, CAI, intake inlet needs to be modified and a tune. Soler makes a very high quality product. I have nothing negative to imply there way but to just bolt on the TB and do nothing else may not net the results they imply. Dont dismiss the product as snake oil it just has to be applied properly. If a guy buys a performance 350 sbc with a big cam. I cant tell you how many guys will complain the engine is a bag of shit. Then I find out they have a stock TC and a 2.56 gear ratio which dont complement the engine properly. Sometimes when you change a part you will have to change 3 more to make it work.

72 mm Stock TB effective WOT area = 3350 mm^2 (not a true full circle) 72 mm Stock Manifold area = 4070 mm^2 (true 72 mm circle area) 76 mm Ported Manifold area = 4540 mm^2 (true 76 mm circle area) 84 mm Soler TB effective WOT area = 4550 mm^2 (not a true full circle) So with the stock manifold, you gain 720 mm^2. With a ported manifold you gain 1200 mm^2. There will be nothing worse than a step down (discontinuity) from 80mm TB to 72mm manifold, the straight taper in the Adapter Plate definitely eases the transition, especially when compared to other Adapter plates that are not tapered. We are 100% sure that adding a radius in such a small distance will cause flow separation. Quote:

Notice we do not claim any power increase, we simply claim our TB's will give much more air at low throttle for a better response. At WOT we can only claim larger air handling capacity, the power will come from applying it correctly as you said. Thanks, |

This turned into a great discussion. Thank you for writing Mike. I wish you could do a thicker adapter but I know you can't to keep ease of install.
I only have one question. I was wondering if you could explain "our throttle tb's will give much more air at low throttle for a better response" in a little more detail. I'm curious what "better response" means. What measure did you use to come to this conclusion? I'm interested in how you "measured" better response. I'm not questioning your statement just interested in the details. Thank you for your time Mike. |

It can also be expressed as the time needed for the maniold to go from an initial to a final set pressure. I'm sure there are other ways to quantify it. The inertia of all the moving parts and the vehicle itself should be in the denominator for the full picture, but that is something we cannot change and has been considered a constant.

Solar 84ml TB & JacFab ported intake mani
Got the 84ml TB in from Solar Performance! Thanks Mike! Decided to also get the ported intake manifold from JacFab to pair with it. Figured I'll just wait and do one install. Expect I'll need to have Will do a retune after the install. Hoping they compliment each other for a few more HP.

Unlikely I'll dyno it. Just not wanting to spend $$ that could go to future mods. Once I am FBO I will dyno to see where the car is. Then wait till I can do the Overkill stage 2 setup to dyno again. I saw that video as well so I figure 20 HP is realistic. plus he didn't have it tuned after to get the most HP out of it if i remember right. I'm gonna have it re-tuned after install. |
