ACE new product develop question
For the racing enthusiasts out there, we'd love to hear your thoughts.
It takes a year or two to do good product development on a new style header. Here's a comparison of our prototype "cross-fire" with 63-76mm frontpipe. Torque dips at 3500-4500 but our car rarely drops below this with our gear selection. What about you? Should we develop? (sorry no pics for a while) |

My 2 cents would be - depends on to whom you are going to target it for. While track drivers indeed often keep engine in high-rpm powerband .. there might be more customers that are daily-driving car then ones for which it's track-only, hence higher importance of power output in low & middle rpms and fix/absence of "torque dip" altogether. IIRC Nameless given choice of slightly higher top numbers or better middle "under curve" gone for later choice.
But then again if it's targeted for daily drivers, i'd think of other design choices aswell .. like option of catted header, and stock-looking heat-shield for those countries, where there are stricter smog / aftermarket parts checks .. or maybe even another option, like easy to remove or install back just Cat part, so that customer can have best of both worlds, most power or more legality, without taking whole header off for replacement. EDIT Ouch, missed "For the racing enthusiasts" at beginning of post .. then if it's targeted this way from beginning, max numbers at top rpms might be of higher importance from get go. |
