Ok, problem with the extended redline expected of me...it cannot happen.

Here's the best way I can think of to describe the problem:


Now notice, that in a clockwise rotational motion around the tach, once you get past the 8, you're in the spot where, on foreign Sols, the overheated cat warning light is. Our Sols don't have this indicator, but the housing for it remains. If I were to extend the numbering, it would overlap that area, and you would end up with a dark spot...meaning, nothing past the spot where the OEM tach ends will light up.

I can do the 140mph speedometer that some have requested, but this sort of extension on the tach is impossible.

So for those of you with swaps that want accurate tach readings, I'm afraid your only solution will be to find a VTEC cluster with the numbering you need.
