To Archie, regarding the "Dragon big oval throttle body ported by POSI ":
I read 50/50 good/bad on the Dragon from others on forums like svtperformance. Many do go with the Dragon though.
here's why I picked the Billetflow:
On the Billetflow, I read all good (except the higher cost than say an Accufab), specifically (from what I've read from others on forums like svtperformance, plus the quote below from their site is a reassuring claim. If it isn't true, then it's false advertising):
"We are the ONLY manufacturer to use proper cam geometry on an oval throttle body for proper pedal height and feel. We are the ONLY manufacturer to use proper cruise control button location for trouble free cruise control use. There is no need to worry about blade screws coming loose and going through your supercharger and destroying it as we crimp the retention screws just like OEM... can the others say that?"
To me being the "only" vs. "the best" are different claims. In the realm of monos, I have read by many, that the cruise control not working at all or sticking is a problematic symptom of the mono style TB. If they are the "only" mono TB that resolves this problem, doesn't it make it the "best" by default? But if they just stated what most parts companies state (Something like: "We are the best throttle body on the market" or "We are the best supercharger on the market") that holds no weight in comparison in my mind.
Is my logic correct? I have no idea.
My first cause for concern would be that it (any part for that matter) works right, and secondly, the part(s) helps in someway. Because if it doesn't work right, then why have it; and if it works right but doesn't help in any capacity, then why have it?
