[QUOTE="Swiss, post: 389252, member: 26417"] Rich, Since I have been building custom 1-off meg systems for about 12 years now, I can appreciate that you have finally found Megaphones. The typical problem with most of the "production" megs from the So. CA companies in the past is that their tuning was often wrong. A GOOD meg system WILL provide a good general increase in performance in MOST areas of the powerband. A custom pipe/meg can increase power beyond that, and match the engine for tuning. Getting down to the last available hp is pretty hard to do, and would require adjustments for just about everything else that is tunable in the engine system. It CAN be done, but would require mega hours of Dyno/Track time and would stray from the "perfect" system with each additional mod that you made to the engine. IF you want to try it, a good meg system will allow you to use a LOT more carb than a straight system. In truth, most of the Tapered and stepped systems are just mimicking the tuning of a meg, but less effectively. Megs are sometimes difficult to fit correctly within the typical frame design, and doing so becomes a job for a good fabricator. I will be looking forward to your testing results. Besides noise, will you be giving out the full dyno results? Looking forward to seeing your info. Swiss [/QUOTE]
