If you look at my first post.....there are still no answers to the questions. You if want specific answers, we need to hear specific questions. My point of view would most likely envolve lengthy post replys. Let me put it another way. To correctly tune a Holley or a Q-Jet really takes about 80 hours of tuning. Think about how many hours on a keyboard.
Next, A set-up, well tuned Q-Jet will cost very similar to a HP series carb. As for the 'Pro Systems' products, why would I buy one of the priciest Holley Tuner carbs? Most of the mods that the 'Tuners' do is what you find on an out-of-the-box HP Series, with no added expense. All out race car or all out street car.... the carb has the same function. The more tuneable the fuel mixture, the cleaner, the more efficient and of course, the power produced. It doesnt mean that a carb that runs good on race car wont run as well on a street car. In fact, most street cars would greatly benifit from its use. All the money you spend getting it to where it can be and where you start from with a carb of this type, just saved you money right up front. Just think, put a 600/650cfm HP series carb on that 13 second car and tune it, it might just run in the 12's.
I see your point. Cost is a big deal. As the old guys taught me, "Do it right the first time or dont do it at all. If you dont have the money....save it up. Then get on with it. It's better to spend your money once, instead of too many times".
And to think, 68hotrod just wanted us to share our ideas. If he has the budget, allow him to spend his money as he feels fit. A $16 Q-Jet is just that....a $16 Q-Jet. I havent known one person/team that runs a $16 Q-Jet that didnt make more efficient power with that of a Holley.
Onovakind67, maybe if you took off the Q-Jet and learned to Tune a Holley like you have with a Q-Jet, you just might be a convert. I'll even give you a Holley.....
But then again what do I know? Its just a supported opinion.
