Ive had a home built flow bench on the very back burner for eons but as it stands right now Im completely out of room to put it. Doubt Mrs myclone would allow it in the spare bed room...

That is a good way to build a cheap flow bench...... but I don't really care for that site seeing as you should not perform professional work yourself. After being around head porting for years, I still find it unbelievable what we get sent to fix from DIY'ers. Although it is quite easy to clean up a set of heads, heavy porting is not for DIY'ers. What's next, Upping displacement with a circle saw? The flow bench is a good idea but one of that magnitude is only good for an idea. If you plan on bumping up your flow a few CFM, its a great site. But DIY'ers need to be overly cautious or they will be paying big money to have their mistakes fixed. Just my .02 cents.

that's why you get a cheap set of heads and research everything before jumping in not knowing what you're doing. if everybody decided not to do their own work, how would anything ever get done?
i agree that just because someone builds a flowbench, doesn't mean they're automatically going to know how to port heads, but you have to start somewhere right?

Re: good diy site
Neat site.
Actually, the one I'm accumulating parts for is an annubar based one.
The sensors for the flow element are Digikey pieces, and a Labjack USB
device to monitor the whole thing.
You can build a really simple one with some clear tubing, a sheet of
aluminum with a hole in it, some 3" PVC and a shop vac. The head adapter is actually the toughest thing to fab.
I need to find a cheap source for pitot tubes... gotta build a swirl meter,
and I need 4 skinny pitot tubes to get it done. I have a really sneaky
suspicion about the amount of swirl on cyls 2+5 vs. the rest of the
ports.
tractorsport.com has some really good info on DIY flowbench stuff, also.
It's disgusting what superflow charges for what is essentially a disc with
different size holes in it, and a big vacuum motor.
Later,

That's our old site and our new one isn't official yet so.....
DIY'ers are pretty bad ass. But majority of people "think" they know but really don't. I have the knowledge and the know how to clean up heads. But when you work side by side with a professoinal porter, you learn how much you really don't know. Head flow is not based by how big you can get the port. When you have seen people research heads for years upon years into flow comparison, port characteristics and so forth you realize why pros are actually pros. DIY'ers are great, the more people who can learn the more the technology can advance. But, heavy caution should always be applied seeing as a tiny mistake can turn into a very big expensive mistake.
