Any interest in cams?

[PowerDubs_imp]

That’s not gain from cams, that is the total where I am at now from stock w/ staintune.

At this point cams haven’t done much.

And at this point any gains (other than going be to Guhl for a real tune, fuel AND ign) will get much harder and much more work and expense.

There is more in the engine- but do I give up low end to get there? Probably not for me. Somebody else can chase that. I will continue to fine tune without loosing the character the bike has.

But yea- I’m not done and there is still more in it.

When you say "At this point cams haven’t done much", what do you mean and why haven't they helped? Disregard if it's a stupid question.

They helped, but only a few hp and lb/ft at this point.

An engine is a series of parts that all can limit or influence airflow. At any point in time there can be a bottle neck anywhere in the system.

Move one chess piece and the target moves.

Easy enough to just go crazy and increase the size of everything. But make something too big and you loose power / tq, especially down low. Everything has a balance point, or design objective

I could easily get more peak hp if I wanted to ruin the low end fantastic ride-ability the bike has. My dyno guy was amazed when I told him I could ride around all day at 1800-2k. Many other bikes don’t like to run under 4-5k.

So I am approaching this completely differently than ‘race bike’. And that comes with more difficulty and compromise.

Well that's a nice milestone, i was just thinking rather than putting a hundred dollars in the slot every time you need to check for a result is it possible to have a timed run let say up a hill with wide open throttle and after several times you get an average baseline to compare against future improvements?

nice one Josh!

Problem with that is- I can’t see what rpm changes are effected, can’t account for weather temp, humidity, barometric pressure, etc.

In other words, modern technology allows a much greater level of data acquisition and adjustment that old school ‘street tuning’ would likely do much more harm than good.

I need to throw more fuel at it, and I need to get out to Guhl for a real tune.

But before I do that, I might try to improve airflow a smidge more first.
