Looking at Ivans site....you can get 147bhp with an advancer, ported boots and K&N.....

You need to look at those a bit more closely, bbb.

First graph shows a top end power loss with a 4 deg advancer.  Ivan doesn't recommend them for this motor.

The graphs showing 147bhp were for a motor with Muzzy full header system, not the Full Monty.  The best Full Monty results I've seen were 140bhp.  Your results may vary.

You feel the difference with an ignition advancer as sharper throttle response from idle to around 4k rpm.  It picks up a bit quicker, that's all.  No actual demonstrable gains on a dyno. 

Since most of us don't routinely sit with the revs above 9k rpm, so any loss/extra vibes that high up the rev range aren't a factor.

Not quite sure if your saying its not worth it though....any advance in acceleration sounds good to me....is it something you would recommend and could add to the full monty install
