Shift points..

RE: Shift points..
When you shift higher, the rpms are higher when you hit the next gear, giving you a little more speed once you get there. I know it drops off in the higher rpms, but the boost from hitting the next at higher rpm seems to make up for it.

RE: Shift points..
what momentum would it be loosing. the Idea is to have the rpms as high as possible when your entering the next gear. unless your power curve goes down after like 4500. But if your goes up the hole way(like its supposed to), then the higher you shift. the morepower your engine is in the possition to make.
I'm having a really hard time explaining it. sorry.

Here is a dyno chart from a 1.8t w/giac. This is just an example for the k03:
See how it starts to drop around 5k rpms?
Im sure APR and other chips are slightly different, but from all that ive read, with the k03, the power curves all drop around 5k rpms.

RE: Shift points..
well that pretty wild. I would attribute the power drop primarily to the fact that the 1.8 at a given (5000K) rpm. is drawing "X" amount of air through the prosess of the intake stroke. With the increase in engine rpms. the amount of air needed to "satisfy" its needs also goes up. I'm under the impression that the K03 isn't capable on suppling or "satisfying" the 1.8. So inturn the engine becomes less efficent. the boost may still remain the same thou. I observed somthing back in my hotrod days. When I was building blown engines. the simple act of porting the heads would at time drop the boost by as much a five pounds, yet the engine would perfome better. This could take up pages. so I'll stop now. but thanks for the dyno sheet.
ANd given that dyno sheet I would start by tring out shifiing at 5.5 to 6 or so that the rpms would drop to the peek of the torqu band when I upshifted. lots of trial and erar, to find what would work the best though.
