Thats some pretty sik numbers Jeff, (around 500hp) good effort.
That magical 400kw figure doesn't seem too far away with a decent cam profile.
I noticed you've decreased spring travel to increase the rate & seat pressure, as long as there is no chance of binding & room for more lift I can't see why you wouldn't get even more impressive numbers.
We must hook up as discussed a few weeks ago when I get back from QLD, cheers.
PS: As others have already stated here, it sounds like you'll get a better reception here as opposed to ns.com
