Thermoquad are very good.the transfer system is very good,better than a Holley.
thats why its smoother and revved quicker.the smaller venturi gets you more vaporization as well,and that is why there is more vaporization at ignition time.possibly.
i say possibly because the droplet size thing is full off pitfalls.It is true that the higher the gas level the less timing is required and normally you would expect more power from more vaporization but the timing needs to be correct for it otherwise it will not.
Ignition strength is critical for flame kernal development.
