Who In Their Right Mind Would Bolt A Carburetor Onto The Top Of A TPI Intake Manifold?


Who In Their Right Mind Would Bolt A Carburetor Onto The Top Of A TPI Intake Manifold?

The answer is… Richard Holdener, that’s who. Why? Why not is really the better question. Richard is always in search of data and information, and what better way to test whether a large plenum with really long runners works well with a carburetor or not. Will it get enough signal to pull fuel well? I suppose in some ways the TPI intake is like a tunnel ram when you think about it. Long runners, a big plenum, with a carburetor on top. I wonder how well it would do with TWO carburetors on top? Hmmm, that might need to be the next test.

The big question is, will an intake manifold specifically designed to move air, and not air AND fuel, actually work for both? And will the weird running inlet locations at the plenum do weird things with regards to reverberation in the plenum? There are a lot of yes’s to these questions, but also a lot of sortas, if that makes sense. There is no doubt this isn’t conventional, or that it probably won’t change the induction game, but it sure is interesting to see. The good thing is there is a lot of information here, and Richard goes through all of it after each test.

Richard has arguably done more intake testing than anyone in the industry, and he’s got a lot of testing data to pull from. So watch, learn, and suggest some weird combos. Maybe Richard will test out your idea.

    I have actually seen that at a car show once. Also saw a tpi with longer runners that raised the plenum about four inches. Those runners looked to be well built, but I wondered how well it ran.
