i was thinking along the same lines... ---- the equal length, just get an equal TIMED manifold, where the pulses reach the turbine inlet at even time intervals..

that vids great, there's like 2 guys working at a time, the rest are just standing around, it's like it is city workers or something! haha :P

Like the reply on honda tech said I bet vtec wasn't engaged on the log manifold. There is a huge difference starting at 4800 rpm and I believe that is where vtec engages, concidence I think not.

or it could just be that the log didn't effectively move the extra exhaust gasses caused when the bigger cam profile hit and the equal length did.

mine isnt really a log manifold, the runners mearge to a collector... and my dyno numbers where probly lower cuz my "filter" was clogged/dirty and that turbo was fucked...
and also my engine is a b18b and yours in a b18a

you guys must be talking about when dustin had the regular ls and not the lsv, right, because the last time I checked the lsv doesn't use an ls head.
