I'll just say that my one experience with one...... A qft-q1050......On a roller cammed, Indy headed 572....... was good.
It made a few more hp than a Mighty Demon 850.


A few like 3 or 30?


It was about 5hp.

.028" in Venturi diameter is only going to get you so much.


Thanks for the reply.
I have a Mighty Demon 850 anuular.
(Throttle Bore 1.75 inch Venturii Size 1.560 inch)
The 337 manifold is ported, no room for a 4500 adapter.
Doesn't seem worth the time or expense to pick up 5 hp.



My test was downleg vs downleg.

And, fwiw...... I've been testing for, and sorting out driveability issues on the dyno for 27 years.

The dyno can be used for a lot more that wot testing.
